Good day sir..I have question bout my set up at home..I have a P7000s Yamaha amp and a pair of Yamaha s112 loudspeaker rating 300 RMS and 600 peak 8 ohms..I jst connect an iPhone to test the sound but I'm not getting much loudness sound of it..volume are more than halfway on the amp and the iPhone is almost full..what seems to be lacking wit my connection or set up?..do I need more speakers to add to bang my ears for the loudness I'm looking?..the two Yamaha speakers should be enough to bring much loudness but not getting it..
I have a question for you, sir. Is it possible to connect active speakers to powered audio mixers to amplifiers ( peavy ir2000) and to cross over? Knowing that some mixers have built in the equalization system.
I've seen many of your videos. You don't miss a step. You explain everything as though everyone is a beginner. Every word you use has a purpose. No wasted info. Very knowledgeable. Awesome job!!!
I wanted to thank you. I've just bought a Yamaha MG12 and a Crown power amp. I'm brand new to this side of the gigs and after watching all the videos on both the setups I'm feeling pretty comfortable.
We have been struggling with a corporate installation involving 115 speakers divided into 5 floors. We ran into all sorts of challenges with daisy chains and fire panel patching. The moment I found this video, i sent it out to all the techies, so that they can go back to the very basics. I am so glad that I found this channel - and thank you for the excellent presentation - both technical and verbal. its simply awesome. We will be back for more..... cheers
ZAY Electronics Trading Thanks for getting in touch! Those installation jobs are WAY more complicated in terms of speaker wiring than most of the stuff we do in live sound, especially when you throw in 70/100 volt lines and the fact that so much of your cabling is concealed. I did a little bit of it about 10 years ago and have much respect for companies like yours :)
Mr. Bruno, sir, I have been viewing your videos for some time now. Anything Audio I've ever needed to hook up. I've always referenced your how to videos, your open honest and direct manner the way you present your videos, is spot-on. Thank you for taking the time and sharing your knowledge with others make our lives easier in the realm of audio. Thank you Charles from Mims Florida
Love all of your videos. I've never seen someone so effectively explain concepts like you do. These are life savers for an aspiring sound guy like myself.
Whenever I watch one of your videos a) I stop myself from destroying equipment b) I Come away with a much better understanding of how Hi-fi equipment works. Thank you.
Thank you so much! I deeply appreciate such a professionally made, well-explained video.Had purchased several audio gear sitting around doing nothing for several months, because instructions manuals were, certainly not for laymen reading. Your video made all the difference for me.
Ha ha. Took 25 minutes to get to the information I needed, but when it did, it was EXACTLY what I needed. Very clearly explained. Well done. The rest was good too, but I already understood those parts.
Even after many years I grateful for all the videos you made available for people like us who know nothing about sound, l am learning a lot from your tutorials Sir. God bless you
My first time using a power amplifier. I have used a powered mixer for 20 years and it finally gave out on me. This video was very helpful in how to hook up an "external" amplifier to my passive speakers. Thank you, I have subscribed to your page
Top Tip - I love using 12g cable for the speakers, it is the perfect gauge in my opinion, i will not use 14 or 16 gauge. Also, you need to open up those Neutrik connectors every once in awhile and tighten down the 2 screws that hold the wire, they DO loosen up over time and can drastically effect your speaker output. I was barely getting bass out of a subwoofer one time, and after the gig i opened up the cable and was able to do 3 full turns to tighten them down! Yikes! Great videos, keep em coming! Thank you!
Thank you, Mr Bruno. Your expertise keeps us from making VERY expensive, potential accidents. I eagerly anticipate more of your excellent presentations.
I have been looking for a fair explanation on connecting my passive speakers to a power amp for sometime, and ended up just putting it on hold, until now. I crazy appreciate this video and your thorough explanation of everything. Snap, when you right down things for reference when watching a youtube video, that's a good video =] THANK YOUUUUU
I just have to say you have answered my questions many times you are blessed with a real gift of communication...keep up the good work...GOD bless I am praying for you Pastor Bill
Thanks so much for all your info. I am new to this and the only one now at our church to take on this task. I have learned more from your videos than any thing else or one that I have talked with. Thanks again
This was a great video and just what i needed to make my mind up on a large purchase. It’s been awhile since I’ve had to run down the specs on a system and you answered all of my rusty questions! Thanks a bunch!
Having only dealt with consumer powered speakers, I was mostly just curious what kind of cables passive PA loudspeakers use. Got that information and so much more, yet this video is still very clear and concise!
Thanks God for you Brother, every video that I have seen from you are so well explain that it've been such a great blessing for my church. I will say that besides knowing what you're doing you also have the give of teaching. I'm a musician in my church and it's been over two years we lost our sound guy and we were so bend out of shape for a while until I decided to go on youtube and do some research to try to help our situation. Every video i so were somewhat confusing until I discover you. Thank you so much.
+Carlos Barreto Thank you for the message Carlos, I am very glad that the videos have been a help to your church. We praise God for his gifts and enabling and how one part of the body of Christ can edify another part despite being separated by such a great distance. Please let me know if you have any specific questions I can help you with.
Great video. My amplifier at church keeps going into protect mode when there is too much input from the microphone. So I came here to find some information. I now know that there are few things that I need to check, since I am using passive speakers.
+GLB Productions Hi again! I had a quick question - is it possible to connect my IPod directly to a power amplifier (inuke Behringer 3000) which has 2 XLR 1/4th inch inputs for Ch1 and Ch2. If so, is there a readily available cable for that? Thanks a lot in advance.
+GLB Productions Don't worry about my question Bruno. I think I get the answer: operate the amp in Mono, using TRS feed the signal from IPod to the amplifier input Ch1. The only downside is I wont be getting a Stereo sound - just mono on both speakers. Guess I will need a DAC/preamp or similar device to split the IPod Stero. Thank you so much again!
Rahul Rane I recommend that you do not connect that way as you will be combining a stereo signal into a mono input. See my video on how to connect stereo sources like this to the PA system, it will answer your question: th-cam.com/video/ge4Iynh4rcc/w-d-xo.html
Yes you can. Just to be clear: you are not connecting the amplifiers together, you are connecting the outputs of the crossover to the inputs of the amplifiers. The amplifiers themselves are not connected together!
Bro ..Peavey power amplifier model: CS 3000 ... for parallel mode will press the switch in position from the back panel of the amplifier and if we feed only one input (channel A) will this work both the o/p channel or use patch cable (Y cable) ?

Nice comprehensive presentation as usual. This comment is probably a little out of scope for what you intended but it may interest someone. Q: Can you run 4 speakers per channel? A: No Well not quite right, 4 in parallel No, but 2 parallel sets of 2 in series on each channel, would be a total load of 8 ohm (4 x 8ohm speakers) per channel, so provided the power spec was still satisfied the answer would be Yes, but in this case the power available per speaker would be too low, so still a no in this case. This is how I setup my Amp volume controls. 1st I ensure that a unity VU signal will make it all the way from a single mixer input channel through 1 mixer group, main out & EQ all the way to the main amp. To achieve this (turn amp volumes right down or off) all the mixer controls for that single test channel will be at unity (0 VU) however, the EQ may need some gain switch & fader settings. I use a meter to check there is no loss at the amp input end of the lines. To adjust the amps while saving my ears. I send -20 VU pink noise from 1 mixer channel (I made some noise and tone test files in audacity). I setup a dBC sound meter in a standard location and then turn up that amp channel until the meter reads 70 dBC or 20 dB below whatever maximum sound level is agreed, then repeat for the other channel. So, now I know that when the main desk output meters are at unity, the speakers will be pumping 90 dB (20 above the test) per channel. This means that the system now reliably maxes out at 90 dB or whatever has been decided. This ensures that agreed maximum mean volume is adhered too and will not be exceeded except for the odd headroom spike of course. Those gain switches are wonderful because they minimises the necessary volume control attenuation which is always great from a S/N perspective.
I know a bit of what you're speaking of.. I just love the way you talk.. ultimately I want to connect my home theater system (from 2001-bare wire system) but yet want to connect it to 2 passive monitors..to just make it louder and more punchier!... I really think this helped!... giving credit to the AMP that you showcased, I will look it up and make my decision for purchase. thank you so much for this video!
You're welcome Richard! Remember that power amplifiers are relatively generic - you don't need the specific make and model shown in the video, any quality power amp from a name brand manufacturer will work fine.
Mr Luse, Thank you so much for taking the time to make these videos. They are extremely helpful when i need a refresher course. I like the use of di boxes to decouple your camera's mic from the table!

@@GLBProductions So if I have the Wharfedale Impact Pro 15" speakers (350 to 700 @8 Ohms). I have the American Audio VLP1500, should I have brought the VLP2500 instead?
@@africangodman6145 Speaker manufacturers give a range of acceptable power handling numbers, but in reality it all depends on how loud you need the system to go - even a 1 watt amplifier could be used if you're just listening in your bedroom ;)
Thanks for explaining this, they sort of skimped on this during the Cert3 I was doing. That and the amp systems that we used were always part of the building (installed permanently) so there was no need to set them up with speakers.
Thanks for your lecture, I'm listening to you for the first time, the lectures was very simple, well explained and very clear. Please can you give a video lectures on how to connect audio distribution amplifiers in large systems like in a Church or lecture theaters. I look forward to your response. I'm an audio enthusiast, I have learnt a little bit of audio engineering.......Thanks and God bless you.
That's very informative and helpful. You've solved many of my questions about live setup because of my lack of experience. Thank you, Bruno! Looking to see more of your tutorials!
Chris Jerome That's great to hear Chris, thanks for letting me know! Feel free to get in touch any time you have specific questions, always happy to help if I can.
GLB Productions oh, yes, that's very kind of you, Bruno! I never know how to setup those huge line arrays. How do people determine the frequency ranges that they want to divide for each speaker? What other equipment do we need in the chain and how to connect them correctly? I know it's complex, but hope to hear it from you when you get a chance. Thank you very much!
Chris Jerome Those large line arrays are set up using 3D acoustical simulation computer software, often written specially for each company or even for each array. These programs allow both simulation as well as real-time calculation of the coverage of the system into a given venue - basically what you get is a 3D image of your specific venue showing the sound levels in each sector. It's very advanced and quite impressive to watch! The arrays themselves are controlled by a central system processor that does all of the frequency and power management, including crossover points and time alignment, which is very important for large PA systems. All of this is generally the responsibility of a person called the system technician, which is a separate post from front of house engineer. When I mix on a line array I will always work with a system tech - we will discuss general positioning and coverage of the array but they will do the actual set up, including the angles between each cabinet and the EQ of the array to the room. At that point they will hand over the system to me, and I will do any final EQ tweaks and then mix the show. So as you can see it is really a team effort. Hope that helps, let me know if you have any other questions :)
GLB Productions Wow, thank you so much for your detailed explanation! That's exactly what I'm wondering about. Yes, it's absolutely helpful! Thank you for telling me the right terminologies so that I can do some further research as well. It's a real complex work that requires a lot of team efforts. I see. Many thanks, again, Bruno! Have a great day!
Very informative,, thank you very much... I just acquired two Behringer B1520 800 watt speakers that I plan on using for home audio ,,,buuut to do so I need an amplifier.. I was wondering how you connect speakon cables to regular RCA .. now I realize it goes through the amplifier
You're welcome! You don't connect them directly to each other: you connect the RCA to the input of the amplifier, the output of the amplifier connects to the speakon cables.
Your videos are awesome, I've learned so much !! I saw many of your videos, but I still couldn't figure out something about my setup. I have a Yamaha EMX-5000-20 Powered Mixer, a pair of Passive Full Range Speakers (250-100W, 8 Ohms) and a pair of Active Subwoofers. The Yamaha manual states "Set this as appropriate for the size of the room or the input capacity of the speakers. • 500W + 500W The two internal amps will produce a maximum of 500W + 500W/4W. • 300W + 300W The two internal amps will produce a maximum of 300W + 300W/4W. • 100W + 100W The two internal amps will produce a maximum of 100W + 100W/4W. " I really can't figure out how much power will be delivered to the passive speakers. Maybe 500W/2=250W ?? I want to connect both the two subs and the Full Range speakers to the Yamaha mixer. (I also have an external Power Amp and a crossover, but I don't think they are really necessary) (Sorry for the long question)
God bless you man I been looking all over TH-cam for someone to explaining “OHM” math of passive speakers. Specifically when connecting speakers in Parallel . Like you would when daisy chaining monitors.
Awesome, informative videos. Well spoken, slowly and clearly. I've watched other tutorial videos and found nothing came close to GLB Productions'. Whenever I want info on any audio matter I first consult GLB Production videos if you have them. Thank you, Bruno.

WONDERFUL and complete, simple breakdown. You took me to school today and I thank you good sir!
Thanks Jason, very glad the video was helpful :)
Bro ..Peavey power amplifier model: CS 3000 ... for parallel mode will press the switch in position from the back panel of the amplifier and if we feed only one input (channel A) will this work both the o/p channel or use patch cable (Y cable) ?
Looks correct to me, but consult your owner's manual to be sure. Some amps use only input A in parallel mode, others can use either input.
So many pass over impedance matching and it's necessity, good job on video.
very well explained!

I use a meter to check there is no loss at the amp input end of the lines. To adjust the amps while saving my ears. I send -20 VU pink noise from 1 mixer channel (I made some noise and tone test files in audacity). I setup a dBC sound meter in a standard location and then turn up that amp channel until the meter reads 70 dBC or 20 dB below whatever maximum sound level is agreed, then repeat for the other channel. So, now I know that when the main desk output meters are at unity, the speakers will be pumping 90 dB (20 above the test) per channel. This means that the system now reliably maxes out at 90 dB or whatever has been decided. This ensures that agreed maximum mean volume is adhered too and will not be exceeded except for the odd headroom spike of course.
Those gain switches are wonderful because they minimises the necessary volume control attenuation which is always great from a S/N perspective.
Thanks for the comment Ken, lots of useful information on setting up a sound system to meet a particular loudness target.
I must agree this is one the best instructional videos on this subject!
in a word awesome this guy really knows his stuff and explains it with such clarity very much needed in every aspect thank you
You're welcome Gregg, thanks for supporting the channel.
I know a bit of what you're speaking of.. I just love the way you talk..
ultimately I want to connect my home theater system (from 2001-bare wire system) but yet want to connect it to 2 passive monitors..to just make it louder and more punchier!... I really think this helped!... giving credit to the AMP that you showcased, I will look it up and make my decision for purchase.
thank you so much for this video!
You're welcome Richard! Remember that power amplifiers are relatively generic - you don't need the specific make and model shown in the video, any quality power amp from a name brand manufacturer will work fine.
@@GLBProductions thank you! Thank you for your feedback.. its well appreciated. 😁
Mr Luse, Thank you so much for taking the time to make these videos. They are extremely helpful when i need a refresher course. I like the use of di boxes to decouple your camera's mic from the table!

Literally the best video on setting this shit up man, really appreciate you speaking clearly and nailing everything! Well done!
Thanks Randy, really glad the video was helpful!
@@GLBProductions So if I have the Wharfedale Impact Pro 15" speakers (350 to 700 @8 Ohms). I have the American Audio VLP1500, should I have brought the VLP2500 instead?
@@africangodman6145 Speaker manufacturers give a range of acceptable power handling numbers, but in reality it all depends on how loud you need the system to go - even a 1 watt amplifier could be used if you're just listening in your bedroom ;)
@@GLBProductions Okay, point taken and thanks for your response.
Best tutorial I've run across. Excellent! Thank You
You're welcome Kevin, thanks for watching :)
Very clear, easy to understand, and well done. GLB's videos are always an excellent information source for me.
Thanks for watching Mike!
At 25.10, talking about daisying speakers cabinets, it would be worth mentioning the effect of impedance when doin so. Video was very helpful.
Thanks for watching Joe 😊
Thank you so much, excellent tutorial for me and my audiences. Wonderful teacher you are my kind friend! 🤙
You're welcome Joe, thanks for watching :)
First class instructional video - thank you very much for taking the time to explain this and upload it. Very helpful!!
+qui24able You're welcome, thanks for watching!
Thank You for the time to do this video. It was a great help to me and much appreciated.
You're most welcome, thanks very much for watching and supporting the channel.
Just as elaborate as I want it... Please make a video on how to connect them together with sub woofers in a church setting

THIS. IS. IT.
Thank for your concise and thorough explanation. Subscriber for life!
Welcome to the channel!
I found this to be an excellent demonstration. Thank you so much.
You're welcome Patrick!
This video is great and very helpful. I will be messaging you about my system and to help me correct the hook ups with my PA System, Mixer.
Thank you for your presentation, I learn a lot from your teaching
You're welcome Jaime.
Thanks Bruno . Great lesson on using amplifiers for Live Sound.
You're welcome, thanks for watching!
This guy is the best. Such command on his work.
Thanks Rahul :)
Thanks for explaining this, they sort of skimped on this during the Cert3 I was doing. That and the amp systems that we used were always part of the building (installed permanently) so there was no need to set them up with speakers.
***** You're welcome, glad the knowledge was useful :)
You’re explanation is super effective. Thank you so much!
You're welcome :)
Thanks for your lecture, I'm listening to you for the first time, the lectures was very simple, well explained and very clear. Please can you give a video lectures on how to connect audio distribution amplifiers in large systems like in a Church or lecture theaters. I look forward to your response. I'm an audio enthusiast, I have learnt a little bit of audio engineering.......Thanks and God bless you.
You are great at telling the whole process. Thanks a lot.
You're welcome, thanks for watching :)
Great information very easy to follow and comprehend. I see that others have give you rave reviews and I must say well deserve.
Very glad the video was helpful :)
Very instructional and useful. Thank you so much, from the Philippines.
You're welcome Hector!
Watching this in 2020. Great thorough explanation my friend. Thank you.
Still responding to comments on this in 2020 😎 Thanks for watching Diego, glad the video was helpful 😊
Very informative with a lot of details with patient explanations
Thanks Moses.
That's very informative and helpful. You've solved many of my questions about live setup because of my lack of experience. Thank you, Bruno! Looking to see more of your tutorials!
Chris Jerome That's great to hear Chris, thanks for letting me know! Feel free to get in touch any time you have specific questions, always happy to help if I can.
GLB Productions oh, yes, that's very kind of you, Bruno! I never know how to setup those huge line arrays. How do people determine the frequency ranges that they want to divide for each speaker? What other equipment do we need in the chain and how to connect them correctly? I know it's complex, but hope to hear it from you when you get a chance. Thank you very much!
Chris Jerome Those large line arrays are set up using 3D acoustical simulation computer software, often written specially for each company or even for each array. These programs allow both simulation as well as real-time calculation of the coverage of the system into a given venue - basically what you get is a 3D image of your specific venue showing the sound levels in each sector. It's very advanced and quite impressive to watch! The arrays themselves are controlled by a central system processor that does all of the frequency and power management, including crossover points and time alignment, which is very important for large PA systems. All of this is generally the responsibility of a person called the system technician, which is a separate post from front of house engineer. When I mix on a line array I will always work with a system tech - we will discuss general positioning and coverage of the array but they will do the actual set up, including the angles between each cabinet and the EQ of the array to the room. At that point they will hand over the system to me, and I will do any final EQ tweaks and then mix the show.
So as you can see it is really a team effort. Hope that helps, let me know if you have any other questions :)
GLB Productions Wow, thank you so much for your detailed explanation! That's exactly what I'm wondering about. Yes, it's absolutely helpful! Thank you for telling me the right terminologies so that I can do some further research as well. It's a real complex work that requires a lot of team efforts. I see. Many thanks, again, Bruno! Have a great day!
Chris Jerome You're welcome Chris, you have a great day too :)
Very informative,, thank you very much... I just acquired two Behringer B1520 800 watt speakers that I plan on using for home audio ,,,buuut to do so I need an amplifier.. I was wondering how you connect speakon cables to regular RCA .. now I realize it goes through the amplifier
You're welcome! You don't connect them directly to each other: you connect the RCA to the input of the amplifier, the output of the amplifier connects to the speakon cables.
Your videos are awesome, I've learned so much !!
I saw many of your videos, but I still couldn't figure out something about my setup.
I have a Yamaha EMX-5000-20 Powered Mixer, a pair of Passive Full Range Speakers (250-100W, 8 Ohms) and a pair of Active Subwoofers.
The Yamaha manual states
"Set this as appropriate for the size of the room or
the input capacity of the speakers.
• 500W + 500W
The two internal amps will produce a maximum
of 500W + 500W/4W.
• 300W + 300W
The two internal amps will produce a maximum
of 300W + 300W/4W.
• 100W + 100W
The two internal amps will produce a maximum
of 100W + 100W/4W. "
I really can't figure out how much power will be delivered to the passive speakers. Maybe 500W/2=250W ??
I want to connect both the two subs and the Full Range speakers to the Yamaha mixer. (I also have an external Power Amp and a crossover, but I don't think they are really necessary)
(Sorry for the long question)
Hi there Dom, I had a look through the manual for this product and couldn't find the section you are referring to - could you send me a link?
@@GLBProductions Hi there, I finally figured it out. The amp produces 325W+325W / 8Ω . It is on page 14 and 30 on the manual.
Thanks for your time !!
@@dom331 That's great Dom, all the best with your music!
wow, very practical instruction. thank you for not getting too technical or on tangents
You're welcome Ryan.
Excellent video....you explain things at a good pace & very clearly. Thank you.
Thanks Brian, glad the video was helpful :)
I'm usually pretty good with stuff like home and car audio but this is new to me
Yes, pro audio has something of a learning curve.
God bless you man I been looking all over TH-cam for someone to explaining “OHM” math of passive speakers. Specifically when connecting speakers in Parallel . Like you would when daisy chaining monitors.
You're welcome, thanks for watching!
Awesome, informative videos. Well spoken, slowly and clearly. I've watched other tutorial videos and found nothing came close to GLB Productions'. Whenever I want info on any audio matter I first consult GLB Production videos if you have them. Thank you, Bruno.
