Did you just make a video on compression that’s helpful and easy to understand? Judging by most of the other videos it must be close to impossible. Well done and thanks.
I'm a drummer doing DIY recordings using a minimal 3-mic setup and this video helps tons. I have the exact Dbx 166 and it adds a nice analog color to the sound as well as doing compression. Thanks.
Over easy being soft knee I assume, I normally attack more and release a lot slower than you have here because I am singing not talking so I base it on that, its great to see such a helpful video on youtube because things like compressors you really will struggle getting it right if you don't know what your doing, I have struggled for years :), thanks
Awesome video, one of the main things I look for in a video tutorial. That being said, I would love if you could do another video like this with the instrument tracks so you can hear how the compressor affects them
Thanks for the feedback. We do live sound only, and have found it nearly impossible to do videos showing how to use equipment (usually not enough time, and too many things going on in preperation for a show). Though, we do have a live event video (recently posted) that shows some of the equipment in action.
It depends on the routing you selected for the channels. In the video, the signal is routed only through the subgroup (which is rather common); though, if the routing (on the channel) was set to L/R, the signal would be routed to FOH L/R and through the subgroup - which you would then balance the signal (if needed) between them.
+rtt143 Attack/release are very important for drums (anything percussive) and bass. They are not too important for vocals and guitars (and most keys). However, vocalists that are very dynamic in their singing may require dedicated attack/release times (to accommodate their style of singing). Though, most vocalists don't need specific attack/release times. I'm not familiar with the 1046, but it may have something in its circuity that determines the "best" attack/release times based on the input signal... maybe similar to the "auto" setting on a 1066.
i just want to know how to patch both dbx compressor in sub group. what i under stand from the video is with 02 compressor we have 04 in / out so 01 drums / 02 bass guitar / 03 vocal / 04 Percussion.
Respect, can you give me advice about settings up my toms on drums, some gigs i have fidback problems when i tune with some resonance drummheads. Thank you
If you are getting feedback, try this (in the order shown): Any of these solutions could correct the feedback problem. 1. Make sure the tom mics are pointing directly at the center of the toms. 2. Reduce the gain of the channel the tom mics are on. It's very common to have too much gain. 3. Use the channel EQ to notch out the frequency causing the feedback... or the frequency of the "ringing" of the drum head. 4. Use a gate on the channel the tom mic(s) are on.
hello dear I don't know exactly to connecting the compressor. Actually, in my material, I have Mixer, Equalizador, compressor, crossover and amplifier. May you explain how to connect all of them?. This is my connecting step: Mixer + Equalizador + compressor + crossover + amplifier. but i am not sure it courect or not? thank you very much
You have everything connected correctly. Though, sometimes the compressor is placed before the EQ, because an EQ that is placed before the compressor (depending on how much boost you are applying), can cause the compressor to stay on all the time (which is not what you want). If you are doing DJ (disk jockey) type of work, the compressor should ONLY be used as a limiter for the system, it should not be used as compressor. This is because recorded music is already highly compressed, and compressors can actually cause speakers to burn out (thermal) because the overall level of the sound system is being pushed.
Good question - it depends on the type of bass player and the music being played. For some bass players, having the contour de-activated can help with controlling the bass signal; it adds support to the compression. Having contour activated for bass players works well when the bass signal being produced is at a (somewhat) consistant level and the frequencies are mostly in the lower registers. There's a lot of variables involved, I recommend trying it activated and de-activated to see which best works for you.
+Jamie Murphy Jr. The -10db and +4db settings correlate with the the type of equipment you are using/connecting to the compressor. Most all professional gear uses +4db. Most all home "stereo" equipment uses -10db. To make sure levels are "correct" throughout the signal chain, all gear needs to be set the same (either -10 or +4).
Just couple of quick questions1. Do I need to compress the outputs to my amps2. Do I need to eq the output to my ampsor if I compress the signal coming from the mixer is sufficient enough for a large PA system
+Ricardo Miller The main mix going to your amps should not be compressed at the main outputs. Compressing the main mix will alter the entire sound of the system (which most likely you do not want). Compression should take place before the main outputs (i.e. at the channel level or at the sub-group level). It's ok to put an EQ on the main output of the mix, however, the EQ should only be used sparingly and to only correct issues. Any heavy EQ changes should be conducted at the channel level.
Thanks again for your reply I'm starting to feel a lot more confident setting my sound system up with your help and advice. Thanks again for clearing that up for me
Depending on how you want the bass to be compresses, the Contour switch can be on or off. It the switch is "on", it will allow more bass (below 150hz if I recall correctly) to be passed through; basically, the 1066 becomes less sensitive to bass frequencies when compressing. When the switch is "off", the 1066 is more sensitive to bass frequencies and will compress the signal a little more aggressively due to a higher sensitivity. We always enable the Contour setting (i.e. make the 1066 less sensitive to signals) when compressing bass. You can turn it on for bass if needed. Thanks for your comment.
+rtt143 Good question. The channel insert points will affect the input signal, therefore, a compressor used in an insert point will affect the monitors (if the monitors are run from the FOH board). Normally, vocals should not be compressed in the monitors; this allows the vocalist to hear their own dynamics. Assigning a single vocalist to their own subgroup and placing a compressor on that subgroup, will keep the compressor out of the monitors. This is how we do nearly all shows, unless the vocalist requests compression in their monitor. If you have a limited number of compressor channels and sub-groups, your only option may be to place a compressor on a specific channel (i.e. vocalist). In my experience, some vocalists don't care if their vocals are compressed in the monitor, though, others do not want compression.
another question for you this is the system I'm putting together 3 x dual 31 band GEQ dual channel compressor gate limiter crossover subharmonic synthesizer feedback suppressor digital reverb / delay and some QSC GXD amplifiers with build in DSP which will handle the alignment delay, output limiter and 4 band parametric eq per channel I'm Gonna run the crossover in stereo 3 way low mid and high but I also have some tweeters and horns dunno whether they run at different frequency to the highs drivers any help on that would be great. as stated above what order in your professional opinion in what ordwr should I connect my equipment there is too many conflicting ways of doing it is just want your opinion everywhere I look someone has done it differently
+Ricardo Miller Thanks for watching. You have a lot of equipment. Connecting outboard gear (for live sound) is not conducted in a linear manner, which means there's no order the equipment can be connected in. Most all of the equipment you listed should be directly connected to the mixing console. The console should be the hub of all the equipment you have. There's a lot of different variables and ways your system could be setup (far more than there is room to type this reply!) I recommend checking out some sound reinforcement books for a good understanding of how to connect gear. There's a couple of other videos on my channel that may help.
I have compressor and EQ, whats the best method of setting up with powered speakers? Eq will be for monitors . I have a Paevey FX2 24 , i see inserts in channels and in groups , fyi thanks
+rtt143 EQ for monitors is usually placed in line with the monitor sends (I.e. mixer mon.out ---> EQ ---> amplifier/speaker). The EQ should only be used to control feedback (not to improve the monitor sound). Your compressor should be used for FOH only (primarily vocals) and inserted into a sub-group. If you have another compressor channel, it should be used on the drums. If your powered speakers have limiters on them, make sure they are enabled!
+rtt143 It's always best to use an EQ for each monitor mix; it greatly helps with controlling stage/monitor feedback. Though, you are certainly not required to use them! For most of our shows, we use 3 x 2-channel EQ's for monitors (6 monitor mixes).
hey mr stage left audio. I have a question. what should i do in my main out compressor limiter if i use that tune up in my vocal, drum, and guitar. Will i do the same as you do in vocal and drum? will i use a contour and over easy? and will i activate the sc enable?
I'm not sure if I understand your question... but, if you are using a compressor/limiter for your main output, make sure the limiter is the only section utilized. It is not common to place a compressor on the main output; doing so usually results in other problems. But, placing a limiter on the mains output can protect the system, but only if the limiter is set correctly.
stageleftaudio ok thank you so much. im sorry for my english word. im not too much good in english. :) but i understand what you say. i just want to use the compressor limiiter in main output to protect my raw driver unit speakers and amplifier. so i just activate those two. the overeasy and cntour. :) im just planning to build up my pa sound system here in the Philippines. :) you know its a part of our culture here. :)
Would compressors add value to a subgroup of instruments in a live set up? I was thinking of grouping the Keyboard along with the Guitars. If not, what would be normal practice for the instruments? Do they go straight into the main mix (with perhaps some effects or EQ), or through a compressor first? I asked because I saw that your set up has only a limiter between the main outs into the amps and all compressors are as inserts into subgroups. Thank you and more power. Awesome videos. I was hoping to imitate your set up as close as possible.
+Zaldy Chua Thank you for the comments. Many times (and depending on the number of instruments, among the many variables), we group guitars/keys into a subgroup and apply a compressor. However, the compressor is set to only compressor signals that may become "too loud". Compressor threshold is usually set high, ratio is set to around 2:1, many times the attack/release are set to "auto". With these settings, we don't to compress any signals unless it is actually needed. For shows with one or two guitarists and maybe one keyboardist, we run their channels straight to the main mix.
hi, nice vid, 1 question i have, when live mixing, eq, comp and effets to kick,tom, vox, snare hi hats are different, soto have diffrent eq and comp, do i need to have multiple externel eq,comp for each chnnel to kick, tom, snare, hi hats,tom, vox????
It's up to you if you want to have multiple external processors; though, they are certainly not needed. Having a lot of processors would require a lot of work to get them tuned for each instrument, and could require a lot of rack space. If you were recording, then maybe you would need that level of control. But for live sound, it's not needed. However, for some digital consoles, you may have to assign compression/gate/EQ to each channel because some digital consoles do not have subgroups.
DJ Hanson , for the most part, you cannot simply plug a microphone into a compressor. Microphone level is not high enough to be affected by most processors, including interfaces. In most cases, preamps are required to bring the signal up to line level. There is one exception that I know to this rule, though. The LA2A has enough gain that supposedly it can be used as a preamp, so long as you don't need phantom power. Now, I don't know this to be absolutely true, this is just what I've heard.
stageleftaudio a potentially easy solution would be to film you mixing live, then narrate it later and make it instructional. but i'll be looking for that video. thanks!
+Uroy Music It's dependent on what instruments need dynamic control some if not most digital mixers come with a compressor on every channel but my recommendation is that you learn how to use a compressor by listening and trying out software audio compressors like the waves brand CLA-2 and CLA-76 or your DAW's compressors and learn them before ever using them in a live situation. Compression, limiting and dynamics control in general is not an easy thing to master. The player should have the ability to control their own dynamics (how soft or loud they are playing) but when they need more than what they can control then that is when you know you need a compressor or limiter.
+Uroy Music It depends on the instruments. For us, we use mostly 4 compressors (vocals, drums, bass, and instruments). The compressors are used on the boards subgroups.
I'm very new at this "compression" havent bought a unit yet, though ive been mixing sound 20+ years ( small venues) . would i still need it if doing a large event with 3 acoustic guitars and 1 micd standup bass with 3 vocals? and do i need a compression unit each for vocals and instruments?
+rtt143 Not every instrument or vocalist needs compression. However, compressors greatly help with controlling the dynamics of instruments and vocalists. Compressors are tools and if used correctly, they can greatly increase the quality of the mix; however, if used incorrectly, they can destroy a mix. If used correctly, the compression of vocals (and instruments) will be seamless to the guests attending the show. For the instruments and vocals you mentioned, a compressor on the vocals would be highly suggested. The standup bass may need one, but really depends on how well the bass player can play the bass. Compressing the vocal channels individually would be best, however, placing the vocal channels into a sub-group and then compressing the sub-group will work. Compression on an instrument or vocal should only be activated when the level of the signal passes a certain point. It can take a little time to get a compressor configured - don't rush into setting levels without testing them.
+stageleftaudio thanks for your expertise. when you say compressing individually, you mean i need a compression unit for each vocalist?, sorry for the ignorance, very much a newbie. i havent seen the back of one as far as inputs and outputs
+rtt143 Sometimes, a compressor is needed for each vocalist, however, if there is only one lead singer and the other vocalists are backup singers, placing a compressor on just the lead singer would work well. Most compressors are either 2 channel or 4 channel; so if you have a limited number of channels, you'll need to choose wisely what channels get compression. There is no set way of using compressors in a sound system. Each system (or each band... or each event) can dictate how a compressor is used and how many compressor channels are needed. Some events require more channels of compression than others.
+stageleftaudio most of the groups i do sound for sing in unison/harmony , theres no 1 singer that stands out...so say if i had 4-8 singers, how many rack units do i need? or is there one unit that can accommodate all? thanks
+rtt143 If everyone sings harmony, put their channels into a sub-group on the mixer you are using - and then place the compressor (as an insert) in that subgroup (assuming your mixer has sub-groups and an insert for the sub-groups). This way, only one compressor is needed for all the singers. Also, because everyone sings together, the compressor settings (threshold, attack, decay, ratio, etc...) can probably be set low (i.e. only turning on when needed). If you have 4 - 8 singers, you'll need 4 - 8 compressor channels if your mixer doesn't have a subgroups. If your mixer has subgroups, you only need to use one compressor channel. Most compressors have either 2 or 4 channels per rack unit - this will equate to needing anywhere from 2 to 4 rack units.
so being a newbie to compressors, i really need to play with this before actually using it "live". where do i get some audio samples vocals, guitars, etc to test? do you recommend this option?
+rtt143 Yes, you will need to be familiar with how the compressor works before using it "live". There may be some vocal samples here on youtube, however, (if you can) I recommend using your own voice while learning the compressor. Using your own voice will allow you to control and fluctuate your own volume level as needed while learning the controls of the compressor "live". Audio samples can work, but may lack the range of "live" vocal. Samples of guitars and drums should work out enough to get you started. The dynamic range of "live" sound is exponentially greater than what a sample can provide. However, the samples should get you started with learning how to control instruments.
the best way in my opinion, and not just for working with compressors is to get your hands on the actual gear that you're interested in learning (compressors for your case) and run a multitrack recording of an event and mix it. mess around with the EQs and the parameters.
More than likely, no. Microphone "native" levels are usually way too low; you will need some type of pre-amp between the microphone and the compressor input.
A compressor would allow your voice to be louder, but may not be able to "isolate" your voice; also the use of compressors on monitors is not a common practice. Assuming you are using monitor speakers, issues with isolating vocal frequency ranges usually involves an issue with EQ, vocal volume, speaker placement, or sometimes the type of speaker. What is your setup?
Thanks for responding! My system ( for rehearsal generally) is an analog Peavey XR 8600 powered mixer and I use in ears with a small Behringer mixer for the click and my mix. I either use a Sennheiser mic or Shure.
OK. Working out monitor issues can be involved. Make sure your IE are fitted correctly for you. Many times, the position of the IE within the ear can change how the IE sounds. Make sure your vocals (in the monitor send for you vocal input) is turned up enough, and make sure the master monitor volume send is turned up as well. Also, make sure other instruments within your monitor mix are lower in volume than your vocals. Set the monitor EQ flat. While you are talking or singing, gradually start to reduce the 120hz freq. to see if that helps with isolating your vocals... if it does not, put the 120hz back and reduce the 250hz a little at a time. If this does not work, you may have to just increase the volume level of your monitor send louder. Subtractive EQ is usually applied first to correct tone and isolation quality issues.
What settings do you normally use on the limiters when you use it as an inline speaker protection? I had a pop and it destroyed one of my speakers and I don't want that to happen again. At that time I was using a 1066 with the limiter set to around +14.
There's a few variables involved with setting a limiter. A limiter is set differently if the signal it is "limiting" is for a full-range signal, or for bass, or for mids, or for highs, or for mid/highs. Also, it depends on how you are running your speakers (at either continuous power or "program" power). Other factors include the power of the amplifier, and the rating of the speakers. We use the limiters in our 1066 units for controlling the signal level of the subgroups... not for running inline with the signal that is feeding the amplifiers. Using them to "limit" the signal levels of the subgroups, we set them around +9 to +14db for drums and around +6db for vocals. We use them to "hard limit" any transients before the signal ever leaves the board. However, people do use the 1066 units inline with the amplifiers (only as a limiter though). The +14 level is rather high for an inline limiter setting. If you are using a 1066 as a limiter in a full-range system, try a setting of +6 to start with. The +6 setting is allowing 4 times the amount of signal to be passed to the amplifier before it is limited. It's easier to blow a mid-range and high-freq. speaker than it is for a bass speaker. Mid and high freq. speakers need limiting earlier than bass. Limiters should NEVER be used to compress a signal (compressors are used for that). The limiter is only there to protect the speaker(s) of high transient/voltages. If the limiter light is coming on often, it's usually an indication the sound system may not be large enough or powerful enough for how it is being used. It's ok for a limiter light to occasionally come on, but be careful if the light starts turning on more.
+stageleftaudio thanks but your reply was truncated. What setting do you use again when you use it inline? Also, when you use it for subgroups, do you just have the 166 as your inline final limiter? What settings do you use on that? And what do you use for your bass/keys/guitars subgroup as well?
On my previous response, click on the "Read more" link to see the rest of the text. For your question, we use a dbx260 for FOH limiting (lows and highs are limited separately). Unfortunately, it's impossible to give a single limiter setting that will cover everything. There's too many variables involved with setting a limiter. For your question, I recommend looking at the dbx forum (www2.dbxpro.com/forum/viewforum.php?f=27) on setting limiters. They have some great information over there that will help you determine what limiter value you should be using for your system.
+stageleftaudio thanks a lot. I think it was my mobile that truncated the message. So when you use the limiters in subgroups, are you doing that as part of the speaker protection? I'll check out the link, thanks. Also, I saw in one of your set ups that you used a 16 ch Presonus mixer. How do you compare the digital compressors there vs the 1066 and other rackmounts? Am I better off buying something like a Presonus studiolive 16.4.2 than an entire rack of processors for a relatively comparable cost?
The limiters used in our subgroups are not used for speaker protection, but are for signal level protection for the board. Our DBX 260 provides the limiter protection for the speakers. The compressor in the Presonus board in that video is basic. The 1066 compressors provide much more control over compression than the Presonus. However, the larger Presonus boards (24.4.2, 32.4.2) provide much more control over compression than the Presonus board in the video.
+rtt143 If there's a lead vocalist, they get their own individual compressor. If there are backing vocals, they are placed into a submix and compressed. If there are more than one lead vocalist, each lead vocalist will get their own compressor. Lead vocals will usually require different (more aggressive) compression settings than backing vocals.
+stageleftaudio Would You Recommend This Compressor Or The Dbx 160a For Vocals. I Have A Deep Voice & When I Record In My DAW Certain Words Peak ? Which Compressor Is Transparent, Clean No, Color / Warm
+GENERAL KING We do live sound only, no recording. With that stated... choosing a compressor can be a very personal decision. The DBX units are great for live sound, but for recording, other compressors may be a better choice. If you're looking for a compressor that is transparent, clean, warm, etc... there is no one answer. I recommend listening to several compressors and making a selection based on what you hear and what your needs are. Of the 1066 and 106a units, they are both good.
I'm just curious, why so few of audio professionals are able to properly record their own voice? They can have whole lot of pro grade equipment at their hands, worth thousands dollars, but what we hear is indistinct noisy bumbling randomly panned around.
Actually, the fastest attack and release are dialed in toward the left. If you notice the level markings on the knobs, they correlate with how many db/mSec and db/sec that the change will take place for attack and release. The fast attack times for the "attack" knob are dialed in toward the left. For example, the higher the number... the higher the amount of db that is affected every mSec (for attack), and the lower the number, the less amount of db that is affected every mSec. Most all compressors function with the fastest attacks toward the left of the dial, and the slowest part, toward the right side of the dial.
One of the best explanations of ‘attack’ most eloquently explained in the drum section at 06:45. Thank you for this run-through.
Did you just make a video on compression that’s helpful and easy to understand? Judging by most of the other videos it must be close to impossible. Well done and thanks.

Thanks for articulating it so concisely and clearly.
Thanks. I almost had my 1066's right. You really helped! dbx needs to hire you.
Over easy being soft knee I assume, I normally attack more and release a lot slower than you have here because I am singing not talking so I base it on that, its great to see such a helpful video on youtube because things like compressors you really will struggle getting it right if you don't know what your doing, I have struggled for years :), thanks
That was so helpful. Bass player, just acquired a 266xl using on the live drum mix and the bass, handy to have 2 compressors
Thank you! I have a small system with high mids and subs (4 piece band) I sure needed a compressor on the over all output. I understand better now .
Awesome video, one of the main things I look for in a video tutorial. That being said, I would love if you could do another video like this with the instrument tracks so you can hear how the compressor affects them

you made it so easy to understand
how important is the attack and release functions? the dbx 1046 4 channel unit doesnt have it, just the overeasy
+rtt143 Attack/release are very important for drums (anything percussive) and bass. They are not too important for vocals and guitars (and most keys). However, vocalists that are very dynamic in their singing may require dedicated attack/release times (to accommodate their style of singing).

+stageleftaudio thanks chief!! your help is greatly appreciated
+rtt143 You are welcome!
I finally got my compressor ,( 4 channel )... in back of my mixer I see "group inserts" (4) and "group outputs" (4) , which do I use?..
+rtt143 Use "group inserts". You will need special "insert" cables to use the compressor in the group inserts.
+stageleftaudio the TRS with the tip ring split , yes? I got those...btw,on the mixer, what are the group outs used for
+rtt143 Yes, the TRS type. The group-outs are used for sending the sub-group signals to something like a recorder.

how about the setting for guitar condenser mic for guitar?
can i use this in singing live band or maybe in karaoke?
Yes.

can you make a video on how to setup a compressor to the mixing board where I can compress all of the channles
We'll be having other short videos posted in the near future that covers quick topics very similar to what you asking about. Thank you.
Do a more modern one with a digital board?
We may do one covering a digital board. However, the principles covered in this video with using analog gear are the same as with a digital console.
For an overall mix compression. Should I have the -10db button in the back pressed in or out for +4db?? Thanks!!
+Jamie Murphy Jr. The -10db and +4db settings correlate with the the type of equipment you are using/connecting to the compressor. Most all professional gear uses +4db. Most all home "stereo" equipment uses -10db. To make sure levels are "correct" throughout the signal chain, all gear needs to be set the same (either -10 or +4).
Just couple of quick questions1. Do I need to compress the outputs to my amps2. Do I need to eq the output to my ampsor if I compress the signal coming from the mixer is sufficient enough for a large PA system

Thanks again for your reply I'm starting to feel a lot more confident setting my sound system up with your help and advice. Thanks again for clearing that up for me
thank you. this is very informative.
but can we turnon the Contour on the bass guitar?
Depending on how you want the bass to be compresses, the Contour switch can be on or off. It the switch is "on", it will allow more bass (below 150hz if I recall correctly) to be passed through; basically, the 1066 becomes less sensitive to bass frequencies when compressing. When the switch is "off", the 1066 is more sensitive to bass frequencies and will compress the signal a little more aggressively due to a higher sensitivity.
We always enable the Contour setting (i.e. make the 1066 less sensitive to signals) when compressing bass. You can turn it on for bass if needed.
Thanks for your comment.
when using inserts for seperate channel compression, is the monitors affected ? if not, should the monitor mix be compressed?
+rtt143 Good question. The channel insert points will affect the input signal, therefore, a compressor used in an insert point will affect the monitors (if the monitors are run from the FOH board). Normally, vocals should not be compressed in the monitors; this allows the vocalist to hear their own dynamics. Assigning a single vocalist to their own subgroup and placing a compressor on that subgroup, will keep the compressor out of the monitors. This is how we do nearly all shows, unless the vocalist requests compression in their monitor.
If you have a limited number of compressor channels and sub-groups, your only option may be to place a compressor on a specific channel (i.e. vocalist). In my experience, some vocalists don't care if their vocals are compressed in the monitor, though, others do not want compression.
another question for you this is the system I'm putting together
3 x dual 31 band GEQ
dual channel compressor
gate limiter
crossover
subharmonic synthesizer
feedback suppressor
digital reverb / delay
and some QSC GXD amplifiers with build in DSP which will handle the alignment delay, output limiter and 4 band parametric eq per channel
I'm Gonna run the crossover in stereo 3 way low mid and high but I also have some tweeters and horns dunno whether they run at different frequency to the highs drivers any help on that would be great.
as stated above what order in your professional
opinion in what ordwr should I connect my equipment there is too many conflicting ways of doing it is just want your opinion everywhere I look someone has done it differently
+Ricardo Miller Thanks for watching. You have a lot of equipment. Connecting outboard gear (for live sound) is not conducted in a linear manner, which means there's no order the equipment can be connected in. Most all of the equipment you listed should be directly connected to the mixing console. The console should be the hub of all the equipment you have.
There's a lot of different variables and ways your system could be setup (far more than there is room to type this reply!) I recommend checking out some sound reinforcement books for a good understanding of how to connect gear. There's a couple of other videos on my channel that may help.
Can you plug a microphone directly into a compressor and run it independently yourself on stage? thanks
I have compressor and EQ, whats the best method of setting up with powered speakers? Eq will be for monitors . I have a Paevey FX2 24 , i see inserts in channels and in groups , fyi
thanks
+rtt143 EQ for monitors is usually placed in line with the monitor sends (I.e. mixer mon.out ---> EQ ---> amplifier/speaker). The EQ should only be used to control feedback (not to improve the monitor sound). Your compressor should be used for FOH only (primarily vocals) and inserted into a sub-group. If you have another compressor channel, it should be used on the drums.
If your powered speakers have limiters on them, make sure they are enabled!
+stageleftaudio what if i have 3 different monitor mixes? do i need a EQ for each? and I'll be using a stage snake with amps stage side
+rtt143 It's always best to use an EQ for each monitor mix; it greatly helps with controlling stage/monitor feedback. Though, you are certainly not required to use them! For most of our shows, we use 3 x 2-channel EQ's for monitors (6 monitor mixes).
hey mr stage left audio. I have a question. what should i do in my main out compressor limiter if i use that tune up in my vocal, drum, and guitar. Will i do the same as you do in vocal and drum? will i use a contour and over easy? and will i activate the sc enable?
I'm not sure if I understand your question... but, if you are using a compressor/limiter for your main output, make sure the limiter is the only section utilized. It is not common to place a compressor on the main output; doing so usually results in other problems. But, placing a limiter on the mains output can protect the system, but only if the limiter is set correctly.
stageleftaudio ok thank you so much. im sorry for my english word. im not too much good in english. :) but i understand what you say. i just want to use the compressor limiiter in main output to protect my raw driver unit speakers and amplifier. so i just activate those two. the overeasy and cntour. :) im just planning to build up my pa sound system here in the Philippines. :) you know its a part of our culture here. :)
Would compressors add value to a subgroup of instruments in a live set up? I was thinking of grouping the Keyboard along with the Guitars. If not, what would be normal practice for the instruments? Do they go straight into the main mix (with perhaps some effects or EQ), or through a compressor first? I asked because I saw that your set up has only a limiter between the main outs into the amps and all compressors are as inserts into subgroups. Thank you and more power. Awesome videos. I was hoping to imitate your set up as close as possible.
+Zaldy Chua Thank you for the comments. Many times (and depending on the number of instruments, among the many variables), we group guitars/keys into a subgroup and apply a compressor. However, the compressor is set to only compressor signals that may become "too loud". Compressor threshold is usually set high, ratio is set to around 2:1, many times the attack/release are set to "auto". With these settings, we don't to compress any signals unless it is actually needed. For shows with one or two guitarists and maybe one keyboardist, we run their channels straight to the main mix.
hi, nice vid, 1 question i have, when live mixing, eq, comp and effets to kick,tom, vox, snare hi hats are different, soto have diffrent eq and comp, do i need to have multiple externel eq,comp for each chnnel to kick, tom, snare, hi hats,tom, vox????
It's up to you if you want to have multiple external processors; though, they are certainly not needed. Having a lot of processors would require a lot of work to get them tuned for each instrument, and could require a lot of rack space. If you were recording, then maybe you would need that level of control. But for live sound, it's not needed.
However, for some digital consoles, you may have to assign compression/gate/EQ to each channel because some digital consoles do not have subgroups.
Since its coming out of the subgroup, are you balancing the two once you find the sound your looking for or are you just using the subgroup?
DJ Hanson , for the most part, you cannot simply plug a microphone into a compressor. Microphone level is not high enough to be affected by most processors, including interfaces. In most cases, preamps are required to bring the signal up to line level. There is one exception that I know to this rule, though. The LA2A has enough gain that supposedly it can be used as a preamp, so long as you don't need phantom power. Now, I don't know this to be absolutely true, this is just what I've heard.
Whats the best compressors to master music thats seperate from a computer ?
Thank you. Very helpful :-)
do you have any instructional videos for compression on kick drums for live shows?
one where you use actual drums would be a bonus\
thanks
No videos yet; hopefully in the near future we'll have something that covers that exact topic.
stageleftaudio
a potentially easy solution would be to film you mixing live, then narrate it later and make it instructional.
but i'll be looking for that video. thanks!
hey. can i compress the audio player?
You can compress any audio you send to it.
sorry i mean like how many compressor do one need in a stage show
+Uroy Music It's dependent on what instruments need dynamic control some if not most digital mixers come with a compressor on every channel but my recommendation is that you learn how to use a compressor by listening and trying out software audio compressors like the waves brand CLA-2 and CLA-76 or your DAW's compressors and learn them before ever using them in a live situation. Compression, limiting and dynamics control in general is not an easy thing to master. The player should have the ability to control their own dynamics (how soft or loud they are playing) but when they need more than what they can control then that is when you know you need a compressor or limiter.
+Uroy Music It depends on the instruments. For us, we use mostly 4 compressors (vocals, drums, bass, and instruments). The compressors are used on the boards subgroups.
I'm very new at this "compression" havent bought a unit yet, though ive been mixing sound 20+ years ( small venues) . would i still need it if doing a large event with 3 acoustic guitars and 1 micd standup bass with 3 vocals? and do i need a compression unit each for vocals and instruments?
+rtt143 Not every instrument or vocalist needs compression. However, compressors greatly help with controlling the dynamics of instruments and vocalists. Compressors are tools and if used correctly, they can greatly increase the quality of the mix; however, if used incorrectly, they can destroy a mix. If used correctly, the compression of vocals (and instruments) will be seamless to the guests attending the show.
For the instruments and vocals you mentioned, a compressor on the vocals would be highly suggested. The standup bass may need one, but really depends on how well the bass player can play the bass. Compressing the vocal channels individually would be best, however, placing the vocal channels into a sub-group and then compressing the sub-group will work.
Compression on an instrument or vocal should only be activated when the level of the signal passes a certain point. It can take a little time to get a compressor configured - don't rush into setting levels without testing them.
+stageleftaudio thanks for your expertise. when you say compressing individually, you mean i need a compression unit for each vocalist?, sorry for the ignorance, very much a newbie. i havent seen the back of one as far as inputs and outputs
+rtt143 Sometimes, a compressor is needed for each vocalist, however, if there is only one lead singer and the other vocalists are backup singers, placing a compressor on just the lead singer would work well. Most compressors are either 2 channel or 4 channel; so if you have a limited number of channels, you'll need to choose wisely what channels get compression.
There is no set way of using compressors in a sound system. Each system (or each band... or each event) can dictate how a compressor is used and how many compressor channels are needed. Some events require more channels of compression than others.
+stageleftaudio most of the groups i do sound for sing in unison/harmony , theres no 1 singer that stands out...so say if i had 4-8 singers, how many rack units do i need? or is there one unit that can accommodate all? thanks
+rtt143 If everyone sings harmony, put their channels into a sub-group on the mixer you are using - and then place the compressor (as an insert) in that subgroup (assuming your mixer has sub-groups and an insert for the sub-groups). This way, only one compressor is needed for all the singers. Also, because everyone sings together, the compressor settings (threshold, attack, decay, ratio, etc...) can probably be set low (i.e. only turning on when needed).
If you have 4 - 8 singers, you'll need 4 - 8 compressor channels if your mixer doesn't have a subgroups. If your mixer has subgroups, you only need to use one compressor channel. Most compressors have either 2 or 4 channels per rack unit - this will equate to needing anywhere from 2 to 4 rack units.

so being a newbie to compressors, i really need to play with this before actually using it "live". where do i get some audio samples vocals, guitars, etc to test? do you recommend this option?
+rtt143 Yes, you will need to be familiar with how the compressor works before using it "live". There may be some vocal samples here on youtube, however, (if you can) I recommend using your own voice while learning the compressor. Using your own voice will allow you to control and fluctuate your own volume level as needed while learning the controls of the compressor "live". Audio samples can work, but may lack the range of "live" vocal.
Samples of guitars and drums should work out enough to get you started. The dynamic range of "live" sound is exponentially greater than what a sample can provide. However, the samples should get you started with learning how to control instruments.
+stageleftaudio thanks for all your help!!
the best way in my opinion, and not just for working with compressors is to get your hands on the actual gear that you're interested in learning (compressors for your case) and run a multitrack recording of an event and mix it. mess around with the EQs and the parameters.
More than likely, no. Microphone "native" levels are usually way too low; you will need some type of pre-amp between the microphone and the compressor input.
As a singing drummer, I have difficulty isolating my voice from the kit. Would a compressor be useful for this?
A compressor would allow your voice to be louder, but may not be able to "isolate" your voice; also the use of compressors on monitors is not a common practice. Assuming you are using monitor speakers, issues with isolating vocal frequency ranges usually involves an issue with EQ, vocal volume, speaker placement, or sometimes the type of speaker.
What is your setup?
Thanks for responding! My system ( for rehearsal generally) is an analog Peavey XR 8600 powered mixer and I use in ears with a small Behringer mixer for the click and my mix. I either use a Sennheiser mic or Shure.
OK. Working out monitor issues can be involved. Make sure your IE are fitted correctly for you. Many times, the position of the IE within the ear can change how the IE sounds. Make sure your vocals (in the monitor send for you vocal input) is turned up enough, and make sure the master monitor volume send is turned up as well. Also, make sure other instruments within your monitor mix are lower in volume than your vocals. Set the monitor EQ flat. While you are talking or singing, gradually start to reduce the 120hz freq. to see if that helps with isolating your vocals... if it does not, put the 120hz back and reduce the 250hz a little at a time. If this does not work, you may have to just increase the volume level of your monitor send louder. Subtractive EQ is usually applied first to correct tone and isolation quality issues.
That is so helpful!! Thank you!!
What settings do you normally use on the limiters when you use it as an inline speaker protection? I had a pop and it destroyed one of my speakers and I don't want that to happen again. At that time I was using a 1066 with the limiter set to around +14.
There's a few variables involved with setting a limiter. A limiter is set differently if the signal it is "limiting" is for a full-range signal, or for bass, or for mids, or for highs, or for mid/highs. Also, it depends on how you are running your speakers (at either continuous power or "program" power). Other factors include the power of the amplifier, and the rating of the speakers.
We use the limiters in our 1066 units for controlling the signal level of the subgroups... not for running inline with the signal that is feeding the amplifiers. Using them to "limit" the signal levels of the subgroups, we set them around +9 to +14db for drums and around +6db for vocals. We use them to "hard limit" any transients before the signal ever leaves the board. However, people do use the 1066 units inline with the amplifiers (only as a limiter though).
The +14 level is rather high for an inline limiter setting. If you are using a 1066 as a limiter in a full-range system, try a setting of +6 to start with. The +6 setting is allowing 4 times the amount of signal to be passed to the amplifier before it is limited. It's easier to blow a mid-range and high-freq. speaker than it is for a bass speaker. Mid and high freq. speakers need limiting earlier than bass.
Limiters should NEVER be used to compress a signal (compressors are used for that). The limiter is only there to protect the speaker(s) of high transient/voltages. If the limiter light is coming on often, it's usually an indication the sound system may not be large enough or powerful enough for how it is being used. It's ok for a limiter light to occasionally come on, but be careful if the light starts turning on more.
+stageleftaudio thanks but your reply was truncated. What setting do you use again when you use it inline? Also, when you use it for subgroups, do you just have the 166 as your inline final limiter? What settings do you use on that? And what do you use for your bass/keys/guitars subgroup as well?
On my previous response, click on the "Read more" link to see the rest of the text. For your question, we use a dbx260 for FOH limiting (lows and highs are limited separately). Unfortunately, it's impossible to give a single limiter setting that will cover everything. There's too many variables involved with setting a limiter. For your question, I recommend looking at the dbx forum (www2.dbxpro.com/forum/viewforum.php?f=27) on setting limiters. They have some great information over there that will help you determine what limiter value you should be using for your system.
+stageleftaudio thanks a lot. I think it was my mobile that truncated the message. So when you use the limiters in subgroups, are you doing that as part of the speaker protection? I'll check out the link, thanks.
Also, I saw in one of your set ups that you used a 16 ch Presonus mixer. How do you compare the digital compressors there vs the 1066 and other rackmounts? Am I better off buying something like a Presonus studiolive 16.4.2 than an entire rack of processors for a relatively comparable cost?
The limiters used in our subgroups are not used for speaker protection, but are for signal level protection for the board. Our DBX 260 provides the limiter protection for the speakers.
The compressor in the Presonus board in that video is basic. The 1066 compressors provide much more control over compression than the Presonus. However, the larger Presonus boards (24.4.2, 32.4.2) provide much more control over compression than the Presonus board in the video.
The compressor is a dbx 1066
I agree, video on driverack
Whats your preference when compressing vocals?, individual or as submix?
+rtt143 If there's a lead vocalist, they get their own individual compressor. If there are backing vocals, they are placed into a submix and compressed. If there are more than one lead vocalist, each lead vocalist will get their own compressor.
Lead vocals will usually require different (more aggressive) compression settings than backing vocals.
+stageleftaudio Would You Recommend This Compressor Or The Dbx 160a For Vocals. I Have A Deep Voice & When I Record In My DAW Certain Words Peak ? Which Compressor Is Transparent, Clean No, Color / Warm
+GENERAL KING We do live sound only, no recording. With that stated... choosing a compressor can be a very personal decision. The DBX units are great for live sound, but for recording, other compressors may be a better choice. If you're looking for a compressor that is transparent, clean, warm, etc... there is no one answer. I recommend listening to several compressors and making a selection based on what you hear and what your needs are. Of the 1066 and 106a units, they are both good.
Awesome vid thanx
Show this video. I looked at your video and I think you have a DBX DRIVERACK. When der puts a video about it.
I'm just curious, why so few of audio professionals are able to properly record their own voice? They can have whole lot of pro grade equipment at their hands, worth thousands dollars, but what we hear is indistinct noisy bumbling randomly panned around.
I think fast attack and release is when you dial all the way to the right. Not as explained here.
Actually, the fastest attack and release are dialed in toward the left. If you notice the level markings on the knobs, they correlate with how many db/mSec and db/sec that the change will take place for attack and release. The fast attack times for the "attack" knob are dialed in toward the left. For example, the higher the number... the higher the amount of db that is affected every mSec (for attack), and the lower the number, the less amount of db that is affected every mSec.
Most all compressors function with the fastest attacks toward the left of the dial, and the slowest part, toward the right side of the dial.
THANKS
Can't you use real drums when demonstrating compression and gating?
Hopefully during a future event, we'll have time to video a soundcheck setting compressors and gates.
