I think thanks to you when I got mine today it came with an English manual and a Portuguese menu! Got it mostly hooked up but no sound,can't wait to set it up right thanks for your video
This is an amazing piece of equipment for the price. I'm doing a new setup in my 2015 grand cherokee and definitely going to use this. I was using the factory deck going into an audiocontrol lc6i, tapped into the factory amp after its been crossed over and frequency limited. I summed the channels on LC6i but it seemed like I still had a major Drop-off at 30 hz still, and my box was a Transmission line tuned to 33 hz so it shouldn't have fallen off so steep after 30 hz IMOP. This time I think I'll use an LC2i tapped straight off the back of the factory deck before it goes into the factory amp and is limited by crossover points to start off with. Then I'll run the LC2i into this badass piece of equipment. Thats should give me a very percise and full range of frequencies to send to my 4 channel and sub amp vs last setup. Thanks for uplaod. I'll be watching again to set mine up when installed
I have a 2017 Grand Cherokee. Instead of tapping into the factory speaker wiring, I use a Bluetooth receiver and send the signal to the DSP on a 3.5 mm to RCA. Then I distribute the DSP out back to my factory AUX jack. Tuned! Then the other DSP out goes to my subwoofer amp. Tuned! No cutting wires. No bass limiter. No LOC.
I have this same model. Love the bluetooth. By far this is the best explanation of this DSP and other dsp and it not in spanish. Before this I set and forget it. Now I understand other functions to tinker with that previous unaware of.
It’s awesome. I have a ported subwoofer so I played around with the delay for my front main speakers. So now my front is delayed 1204 ms from my sub and it sounds amazing. And you can tune it from your driver seat on your phone in real time.
I'm under very heavy assumption that the distance between your ear and the farthest output of your sub/port is venturing up on 140 feet, my guy... In other words, the setting of 1.204 seconds is excessive, unless you're driving a double stretched Suburban. In my own personal experience (of setting up multiple installs), a simple way to get a great value for this setting is by doing a bit of math with a string, some scotch tape, and a tape measure... I'll explain...
Take the string (about a foot in length) and tape it to your vehicle's ceiling centered between your seat and the passenger side a few inches forward from the headrests (where your ears will be located). You can then either tie a knot in the string or draw on it with a marker where the height of your ears is. From there, you take 2 measurements... One from the furthest point your enclosure produces sound from (whether it's the location of the port or the sub itself depending on your orientation/setup) back to the marking on your string. Write that measurement down, in decimal form. Then take the measurement from the string's marking to the center of your front windshield, doubling that length as your "distance", and adding the two numbers together.... Now, I don't have your DSP, but most of them do time correction offsetting based upon the number you just came up with; the spacial distance of your enclosure and it's inherent reverb. The way my HU's DSP works is by entering that distance and it automatically delays the output of the door speakers accordingly (through a calculation) to allow for the subwoofer in the back's sound to travel the distance to my ear enough that when the doors play, all sound from all speakers hits my ear at the same time (which is effectively what you've done in a more barbaric way with your "playing around" and came up with some absurd numbers because of). That all now out of the way and said, while I know my value for this measurement and how my delays are set accordingly, I don't know yours, but I'd be willing to help... If you can get me the measurements said prior, I can get back to you what your values should be closer to, 'cuz they're very likely to be a (much) smaller one than what you've given them. The smaller the vehicle, the smaller those values need to be, so I doubt you're driving a limousine with subs in the trunk to warrant the 1.2 second delay you've presently set up. If you want my help, it's there for you, but it is after all your vehicle and decision to alter as you see fit and you'd know what sounds best to you in it... That, and not all units processing time correction will do it "the same way", so there are variances to be had... As a side note, if you just want a reference to do the math yourself without the use of my HU's calculation, a highly reputable sound company posted these "standard" values as a chart: 5 meters = 292 m/s delay 10 meters = 584 m/s delay 15 meters = 876 m/s delay 20 meters = 1170 m/s delay or 10 feet = 179.3 m/s delay 20 feet = 358 m/s delay 30 feet = 536 m/s delay 40 feet = 714 m/s delay 50 feet = 892 m/s delay (Which, none of these account for reverb, so I'd recommend doubling to self-correct echoing and is more inline with what my HU will typically project.)

I have had this exact dsp for like 6 months now its a great entry to the dsp world I love it and the price is unbeatable. I do want to speak on the phase tho. I honestly use the phase options all the time. When I unplug my door speakers from the amp my polarity gets messed up a lot and instead of physically switching the wires around again I can easily switch the phase. Also, this dsp does have pink noise but you can only access it from the dsp not with the app
Kick ass explanation! Especially letting them know about Q factor! I own both Stetsom DSP dial models (8 channel & 4 channel) love them but they are used in 1 car. 8 channel handles 2 Massive Audio Blade 4 channels in stereo config and the 4 channel Stetsom is set up for 2 matching blade monos, each channel mono 1&2 out to amp1 then 3&4 out to amp2 both are 1000.1's driving a Helix dual 2ohm coil Esprit 12" Carbon Fiber flat! Then I have a Toro Rage 2 bridge to a Eclipse twin drive center channel that mounts on the rear view mirror, so I ask u will that PX2 DSP drive a center channel signal correctly do u 🤔 currently it's installed but not powered because I ran out of channels! This is a badass build in the trunk of my BMW E46 and I was going to try Stetsom little hide away(remote control) DSP you tested but all my equipment is big and it's my business demo that little box is just too small to show honestly 🤣 Head unit is a Excelon CD/USB/Bluetooth with 5 volt outs pumped through a American Bass 9 band 1/2 Din EQ/8 volt line driver(nice EQ if you've never tried it) anyways what do you think of this dilemma for a guy who's been doing this for 30+ years I'm stumped & brain is locked up! By the way I chose those Stetsom DSP's for the lights to match my MASSIVE amps badges, then they discontinued the Blade V1's with blue power LEDs and went to V2 with a green power(don't match) so I ordered a Toro to match the best I could(you can see it lit on my Instagram) system is in the works but Maine is cold so I have to work in little time slots till spring weather 3 heaters in my garage cost a fortune daily! Great videos keep them going, also got some questions for you about Soundstream Nano 5 channels for.my Mazda 3 demo but I'll hit you up on that later! Peace
Thank you so much for watching and the comment! The DSP will output what you input, so if you are providing it a center channel signal it will output that.
Thank you for the walk thru. I bought this unit but the Air 8 version with a 32 band eq. The software in the app is identical. Some points to note: once you program the DSP, it saves it to the unit, and you can then “boot up” the same settings on any phone that you connect to the DSP, so the “memory” is “transferred” to any phone connected to it. Also, the time alignment is one of the most incredible tools as it helped a massive vehicle like mine (Navigator) finally sound right. All in all, this is an incredible dsp and very easy to use. Thank you for reviewing this.
You have Jesus's work! 😅 Thank you so much for doing this simple overview. It was much needed. Thank you HiFi Vector! I bought the 8 channel unit. And plan to buy another since they are just so darn good value! Man. South America is KILLING IT in the audio world right now!
Always double check your settings after changing them. I found that the Bluetooth is wonky. Sometimes the new settings won’t stick. It’s better to play around in the Bluetooth till it sounds like you prefer. Then go to the unit and input your settings with the dial. This will always ensure your settings are applied
It didn't used to do that... Since I took it out of one car and put it in another car it started that crap and it's aggravating, have you found another work around besides physically messing with the dsp?
For guys using amp with clip light a cool feature on the limiter is to play a test tone say 40 hz until amp clips then minus the limiter until the amp stops clip you can do this with no speakers connected then connect your speakers back to amp after
Try disconnecting any other Bluetooth devices. Sometimes the DSP‘s won’t connect if you’re connected to the Bluetooth on your radio so always connect to the DSP first.
Good day bro.this unit has a 6 channel input.so can i use 6 diffirent full bridge amp.im using tarramps.for example channel 1 n 2 for bass-2 amps 3 n 4 for mids-2amps 5 n 6 for high-2 amps. **the other question is,if im using the channel for high,on what frequency should i put on the LPF and HPF?? your answers means a lot.thanks.
I have a question hopefully I get a response. I have a 4 Channel amp and the 4 miss in my soundbar are wired together and I have them bridged on channels 1&2 and I have my tweeters on channels 3&4. My question is what do I set for the bridged speakers on the app?
You would just cross them over and EQ them how you like on your mids. And if they are all bridged then there is no left right correct both left and right are coming out of mids if they are using only one bridged channel. So the on the DSP going out of DSP into amp just output L&R to your bridged 1/2 ch on amp.
Finally a DSP video i understood with ease. ! Im slowly building my system and originally when i bought my car ( 08 mercedes sl 550 ) it had Bose surround sound. I bought car used and radio worked about a month. When the system worked it sounded really good. I am an SQ guy. I have the recoil red 1800.5 ( because of your review ) ty. I have a mid Tier Kenwood radio with tons of adjustment. Kfc 4707s i think. 4 polk 1042 svc subs in a ported clamshell enclosure thats insanely accurate. I am looking into a DSP unit but i would like one with a surround sound decoder. Like Dolby atmos. I see pioneer has one but has a tiny 50x4 amp with it and dont need it plus too weak .can you steer me in the right direction for something a long those lines ? Or maybe none out there , i dont know. Havent bought new components yet but im leaning towards Blam , morel and Alpine R pros..Thanks for the information so far and apologize for the long comment. Almost no one out there wants to help out. Anyone in comments , id love your feedback as well !
I haven’t seen one myself that does Dolby or surround but then again I haven’t purposely searched for one with surround sound either. I would think the deck would also need to have a surround sound decoder as well a ls the DSP.
I just got mine. I assumed it was a 28 band EQ per channel. It’s a 15 band master EQ. Ugh. Its still an awesome DSP and works well. The manufacturer details are misleading. My old DSP has a 31 band EQ that’s user assignable freq. and Q factor for each channel. But it only worked with a 5V input. And my Bluetooth rig only pushes 2V. I love the app though. No more lugging a Windows PC and cables.
@@johnviera3884 i just checked it out. . .that is the analog audio dsp chip interface. . that chip is used in the same razordsp amp i have and the the dayton audio dayton dsp408 . . its a really awesome chip BUT its a ashamed its not used in more places
@@mikeriverajr4447 I had an output level issue with it. I had very low output to my amplifiers. Unusable even with all gains on full power. The Expert PX2 has a better output level.
I have a 2011 Chevy Avalanche with the Bose upgraded system,with a center channel in the front dash and a sub under the cemter console. I need an entry level DSP that takes speaker level inputs. I'm adding a front sound stage amp and a subwoofer amp. What cost efficient DSP do you recommend?
Regarding input gain and output gain, is the input gain like a master gain level for all channels? Then the output gain is to tailor each channel separately?
No, The Bluetooth on this is only to connect the phone to the DSP to use the settings. But this will not bypass your head unit Bluetooth to play music.
Hello, I have two questions. The first one, which app did you download because it looks different from the one I downloaded? Second question, because Bluetooth doesn't want to work for me?
First narrow down if it’s your amps. Disconnect DSP and go straight to amps and see if the noise is still there. If it’s gone then reconnect DSP and check rca cables and see if you move the RCA’s away from any power cables helps. Then try new RCA’s and check your DSP ground location.
Usually yes it’s good to start out with your HU flat but if you need to tweak it is fine. Just depends on how your HU was designed. Flat on one HU could sound to flat, while flat on another HU could sound great.
How do you connect it to your phone though I turned mine on and I don't see anything under Bluetooth devices and when I open the expert app it just shows a loading screen for forever.
When you open the app you hit the signal icon on the top corner and you should see your DSP listed and select it. Make sure you don't have any other bluetooth connected to the phone.
There is no way I would be recommending this product based on the fact that it is so ridiculously hard to find any sort of support on it. Email the company multiple times and don't get a single reply after days of waiting
When you show the individual channel EQ, there is an F1, F2, and F3. I understand what you are saying when adjusting the F1 but what are F2 and F3? Also, is delay the same thing as what is labeled as time alignment on other DSP's?
This DSP has 3 customizable frequency numbers per channel. This the f1, f2 and f3. Those are the 3 custom frequencies. This is in addition to the main eQ on the DSP. Yes the delay would be same as time alignment …it will allow you to adjust speakers to “hit your ear” at the same time if you have any need for it.
@HiFiVector I think I get it now. If you had any problem areas, you could zone in on up to 3 specific hz. Otherwise, you can only target the areas listed on the master input EQ. Does that sound right?
I'm really exhausted messing with this. I've spent hours trying to get this to work and no luck, sounds horrible. I get the concept of crossovers but they all sound bad and the gain options on this I just can't get right. I feel I'm damaging my system. I'm using a oscope. Whats the point of main in and out gain. I'm one step away just unplugging it
The main purpose of the main input gain is to simply set your input RCA gain. The output channels each have their own gain to fine tune the gain to each output channel RCA. If you are confused just set the output channel gains to all the same value ( say 0 )and then just use your main input gain to control all of the output gains together.
Got a question. I had a Rockford Symmetry epx2 witha 24 band card back in the day. So can you put a y cable on channel one and use that for front highs, one on channel two for front mids, another y on channel three for rear highs, etc. Set the unit at the L+R on each channel in center will it not have to stereo sound that way? And sound weird?The Symmetrys eq was too much but the xovers were awesome and just super control on everything
Yes you can configure it that way. And you would just lose your left and right separation most people would say it’s not too big of a deal but on some songs there is separation that you would miss out on. Also there is another expert DSP with more left and right inputs that might be useful in your situation.
Hey bro. Have had a chance to use any of the newer DSPs by expert? I'm curious if any are "better" than this one. I see one called x6 air for instance. But hard to get info on the new ones
So bro. For instance, I wish my subs hit the 50-60 Hz range harder. Could I do a low q factor and EQ for 50 53 55, on one output channel and do 57, 59, 61 on another output channel. Then take one channel and plug it in my Left input on amplifier and the other on my Right. And by doing this boost those frequencies? Also I know one EQ will cancel another out. My head unit EQ I cannot turn off. Should I just set it flat? Like my phone EQ I can't turn off either so I set to flat. Thank you for all your help bro
Yea try and keep your head unit EQ flat then adjust with DSP. An easier way is to use a lower Q setting ( wider effected frequency range) so if you set your EQ to boost 55hz with a low Q it will boost 50 to 60. That is the benefit of changing the Q. You can have it effect more of the surrounding frequencies or only pinpoint that one frequency.
@@HiFiVector I'm sorry to bother you again but the instructions are kind of vague on this thing. My question is each channel output only has one RCA. So does that mean I have to buy a Y cable leaving the DSP? Going into my subwoofer amp I mean because it has left and right input. Or can I use one channel to go into the left and another channel to the right on my sub amp? Which would be the better way if you can do either? thank you. I apologize for bothering you all the time about this but really the instructions are not for a novice
You can do it either way if you’re not using all your outputs you can just used to going to your subwoofer amp. If you wanna use your outputs for something else just use one to the amp with a Y splitter.
I can't get mine to connect threw Bluetooth, it shows the unit as an available device but won't connect to any phone I try. When the app opens it just searchs but won't find the DSP any help would be appreciated
The only thing I can think of is make sure you don’t have any other Bluetooth connected on the phone. That’s the only downfall is on the phone. You can only have one. Bluetooth device activate a time.
@@HiFiVector I've already tried that I even forgot all Bluetooth connections as a shot in the dark.. I'll try the pro version of the app hopefully that does it. Everything works great, except Bluetooth lol main reason I bought it. Thanks for getting back to me ! Subscribed!
well kinda of disapointed, i have a razor dsp amp that as a analog audio dsp chip in , it givies a 12 band full adjustable eq per channel [Q, FREQ, GAIN] per band this really allows you to shape and correct the sound per speaker, what are you supposed to do with a 3 band??????. . . they really have it back wards, , it should be a 12 band per channel , to shape and correct each spaker and then a 3 band as a eq in to shape the over all sound. . . . I just bought this for a customer project and was hoping it would allow me to tune with a 12 band per speaker like the razor dsp sadly disapointed. . all in all its a great item BUT that fully adjustable 12 band per channel is crucial IF your trying to correct issues. .
@@kaja9917 yep you pin point the exaxt frequency where ever you want from 20 hz to 20,000 hz as well as the width of adjustement and 20db plus or minus gain. .. And i was wrong its actually 10 bands sorry but still 10 exactly taored bands to your needs
Yes. In this DSP you pick the center frequency which ‘sweep” is. Then you change the “Q” which is what width is . The width around the selected frequency.So yes it does just called diggers names.
And I'm not using the DSP for my subs currently but it still cuts out on me then takes a few minutes to kick back on and turning radio off and back on does not turn bass back on however amp stays powered up entire time so it's obviously a protection of some sort I just can't figure it out for the life of me Its only my second full bridge amp first ones I had problems with as well . I'm running #1 welding cable to it from a 60ah a123 bank with stock alt but voltage holds 14s full tilt weird I mean I understand wire capacity but I don't understand how some people are only using 2 agm batteries with 0 gauge wire and there's work phenomenal.
Hey bro. I don't understand the crossover. I'm doing my sub channel. At the bottom it has a number on the left and one on right. Both are adjustable with plus minus. One says hpf and the other lpf. Is the hpf a subsonic?
So in the bottom left set that at like 20 hz or whatever you want yes it’s like the subsonic. The lpf on the right set to 80hz or what you want the upper frequency cutoff you want.
@@HiFiVector bro. How long did it take you to tune this DSP to your liking? Jeez. So many adjustments I can't get it to sound good yet! Lol. I just can't get the subs to sound as good as when I was only running through my head units crossover. Its hitting hard as hell but it's missing certain low notes that it was hitting before. And yes I've played with the 3 band and q factor. Going to continue to do so. Just curious if you might have had this issue also. Thank you for all your help
Anybody have any advice on getting connected to the Bluetooth I cannot get it to connect to my phone for the life of me also does anybody have any sort of information on customer support on this item I have tried everything I've emailed every single email address that I can find that is associated with this company and have got not one single reply
Honestly, I believe there are made from the same factory, so it just depends on the features but I think this one still has the most features at the best price
My sound guy says this is a shit dsp and I should buy a audio control instead but that’s like $800 … he doesn’t want to tune my car with this thing on it . I’m running this in my car right now I don’t know how to use it

I do want to speak on the phase tho. I honestly use the phase options all the time. When I unplug my door speakers from the amp my polarity gets messed up a lot and instead of physically switching the wires around again I can easily switch the phase.
Also, this dsp does have pink noise but you can only access it from the dsp not with the app
Kick ass explanation! Especially letting them know about Q factor! I own both Stetsom DSP dial models (8 channel & 4 channel) love them but they are used in 1 car. 8 channel handles 2 Massive Audio Blade 4 channels in stereo config and the 4 channel Stetsom is set up for 2 matching blade monos, each channel mono 1&2 out to amp1 then 3&4 out to amp2 both are 1000.1's driving a Helix dual 2ohm coil Esprit 12" Carbon Fiber flat! Then I have a Toro Rage 2 bridge to a Eclipse twin drive center channel that mounts on the rear view mirror, so I ask u will that PX2 DSP drive a center channel signal correctly do u 🤔 currently it's installed but not powered because I ran out of channels! This is a badass build in the trunk of my BMW E46 and I was going to try Stetsom little hide away(remote control) DSP you tested but all my equipment is big and it's my business demo that little box is just too small to show honestly 🤣 Head unit is a Excelon CD/USB/Bluetooth with 5 volt outs pumped through a American Bass 9 band 1/2 Din EQ/8 volt line driver(nice EQ if you've never tried it) anyways what do you think of this dilemma for a guy who's been doing this for 30+ years I'm stumped & brain is locked up! By the way I chose those Stetsom DSP's for the lights to match my MASSIVE amps badges, then they discontinued the Blade V1's with blue power LEDs and went to V2 with a green power(don't match) so I ordered a Toro to match the best I could(you can see it lit on my Instagram) system is in the works but Maine is cold so I have to work in little time slots till spring weather 3 heaters in my garage cost a fortune daily! Great videos keep them going, also got some questions for you about Soundstream Nano 5 channels for.my Mazda 3 demo but I'll hit you up on that later! Peace
Thank you so much for watching and the comment! The DSP will output what you input, so if you are providing it a center channel signal it will output that.
Thank you for the walk thru. I bought this unit but the Air 8 version with a 32 band eq. The software in the app is identical.
Some points to note: once you program the DSP, it saves it to the unit, and you can then “boot up” the same settings on any phone that you connect to the DSP, so the “memory” is “transferred” to any phone connected to it.
Also, the time alignment is one of the most incredible tools as it helped a massive vehicle like mine (Navigator) finally sound right.
All in all, this is an incredible dsp and very easy to use. Thank you for reviewing this.
Thank you man yea I like the expert and audiopipe clean dsp.
You have Jesus's work! 😅 Thank you so much for doing this simple overview. It was much needed.
Thank you HiFi Vector! I bought the 8 channel unit. And plan to buy another since they are just so darn good value! Man. South America is KILLING IT in the audio world right now!
You are every welcome I am glad the video helped! Thank you for watching!
Always double check your settings after changing them. I found that the Bluetooth is wonky. Sometimes the new settings won’t stick. It’s better to play around in the Bluetooth till it sounds like you prefer. Then go to the unit and input your settings with the dial. This will always ensure your settings are applied
It didn't used to do that... Since I took it out of one car and put it in another car it started that crap and it's aggravating, have you found another work around besides physically messing with the dsp?
@@1hundredallday close the app. Then re-open the app and log in again.
good job on explaining how it works
For guys using amp with clip light a cool feature on the limiter is to play a test tone say 40 hz until amp clips then minus the limiter until the amp stops clip you can do this with no speakers connected then connect your speakers back to amp after
The 40hz is for bass
Ohhhhhhhhhhh Yeah thanks
Great explanation bro. Just subbed!
Thanks so much!
this dsp does have pink noise but you can only access it from the dsp not with the app
Been thinking about getting a dsp so I just purchased the NVX dsp on their site for $129 normally it's $299.99.
Best video ever, thx so much!!
You are very welcome glad it helped!
I’d really like some info on how to deal with the factor setting
Strange. My unit one day only showed a 15 band EQ IN. Today it shows a 28 band EQ again.
How do you change the default password? In the manual it says the default is 0000 but doesn’t say how to change it.
Great demo thanks for the info
Thanks for watching!
Hi what can I do if I don’t see the dap showing on the app , I can’t connect!
Try disconnecting any other Bluetooth devices. Sometimes the DSP‘s won’t connect if you’re connected to the Bluetooth on your radio so always connect to the DSP first.
Does the px2 have fabric custom settings.
Good day bro.this unit has a 6 channel input.so can i use 6 diffirent full bridge amp.im using tarramps.for example channel 1 n 2 for bass-2 amps
3 n 4 for mids-2amps
5 n 6 for high-2 amps.
**the other question is,if im using the channel for high,on what frequency should i put on the LPF and HPF??
your answers means a lot.thanks.
Can the channels be paired to be adjusted at once? Like if ch1 & ch2 are the FL & FR door speakers.
I have a question hopefully I get a response. I have a 4 Channel amp and the 4 miss in my soundbar are wired together and I have them bridged on channels 1&2 and I have my tweeters on channels 3&4. My question is what do I set for the bridged speakers on the app?
You would just cross them over and EQ them how you like on your mids. And if they are all bridged then there is no left right correct both left and right are coming out of mids if they are using only one bridged channel. So the on the DSP going out of DSP into amp just output L&R to your bridged 1/2 ch on amp.
Finally a DSP video i understood with ease. ! Im slowly building my system and originally when i bought my car ( 08 mercedes sl 550 ) it had Bose surround sound. I bought car used and radio worked about a month. When the system worked it sounded really good. I am an SQ guy. I have the recoil red 1800.5 ( because of your review ) ty. I have a mid Tier Kenwood radio with tons of adjustment. Kfc 4707s i think. 4 polk 1042 svc subs in a ported clamshell enclosure thats insanely accurate. I am looking into a DSP unit but i would like one with a surround sound decoder. Like Dolby atmos. I see pioneer has one but has a tiny 50x4 amp with it and dont need it plus too weak .can you steer me in the right direction for something a long those lines ? Or maybe none out there , i dont know. Havent bought new components yet but im leaning towards Blam , morel and Alpine R pros..Thanks for the information so far and apologize for the long comment. Almost no one out there wants to help out. Anyone in comments , id love your feedback as well !
I haven’t seen one myself that does Dolby or surround but then again I haven’t purposely searched for one with surround sound either. I would think the deck would also need to have a surround sound decoder as well a ls the DSP.
@@HiFiVector thanks for the response. Im not sure as well. Im just now looking into that part of car audio
This helped me a lot ty very much💪
Can any of these dsp be used as my Bluetooth connection rather than having to run a head unit?
The Dayton 408 does but you have to purchase the Bluetooth apparatus seperately
I just got mine. I assumed it was a 28 band EQ per channel.
It’s a 15 band master EQ. Ugh. Its still an awesome DSP and works well. The manufacturer details are misleading.
My old DSP has a 31 band EQ that’s user assignable freq. and Q factor for each channel.
But it only worked with a 5V input. And my Bluetooth rig only pushes 2V.
I love the app though. No more lugging a Windows PC and cables.
yeah i agree,, , pretty shitty.. what was your old one???

@@johnviera3884 i just checked it out. . .that is the analog audio dsp chip interface. . that chip is used in the same razordsp amp i have and the the dayton audio dayton dsp408

@@mikeriverajr4447 I had an output level issue with it. I had very low output to my amplifiers. Unusable even with all gains on full power.
The Expert PX2 has a better output level.
I have a 2011 Chevy Avalanche with the Bose upgraded system,with a center channel in the front dash and a sub under the cemter console. I need an entry level DSP that takes speaker level inputs. I'm adding a front sound stage amp and a subwoofer amp. What cost efficient DSP do you recommend?
BT12 is my favorite.
Regarding input gain and output gain, is the input gain like a master gain level for all channels? Then the output gain is to tailor each channel separately?
Correct
Hey .. this dsp don't have presets available
You can save multiple setting yes
The crossover on the dsp expert or they preset or you can adjust
You can adjust
Can I play music through my phone with the Bluetooth?
No, The Bluetooth on this is only to connect the phone to the DSP to use the settings. But this will not bypass your head unit Bluetooth to play music.
Is this a crossover too
Yes it has very nice crossovers built in with a ton of adjustments.
@@HiFiVector thank u very much
How do I adjust the hpf to 2khz?
Hello, I have two questions. The first one, which app did you download because it looks different from the one I downloaded? Second question, because Bluetooth doesn't want to work for me?
Search for expert electronics in App Store. It has the orange. Color EX on picture.
I don’t know if it’s the dsp or my amps but I got crazy noise with my first time using a dsp in my setup any help!
First narrow down if it’s your amps. Disconnect DSP and go straight to amps and see if the noise is still there. If it’s gone then reconnect DSP and check rca cables and see if you move the RCA’s away from any power cables helps. Then try new RCA’s and check your DSP ground location.
using the expert should everything on my radio be flat?
Usually yes it’s good to start out with your HU flat but if you need to tweak it is fine. Just depends on how your HU was designed. Flat on one HU could sound to flat, while flat on another HU could sound great.
I keep getting noice.whats the problem?
How do you connect it to your phone though I turned mine on and I don't see anything under Bluetooth devices and when I open the expert app it just shows a loading screen for forever.
When you open the app you hit the signal icon on the top corner and you should see your DSP listed and select it. Make sure you don't have any other bluetooth connected to the phone.
There is no way I would be recommending this product based on the fact that it is so ridiculously hard to find any sort of support on it. Email the company multiple times and don't get a single reply after days of waiting
Great video!!
Thank you Added to my chop bag Removing PRV This one 10$ more but BT makes way easier to use
does this DSP allow us to save any presets for diff types of music?
Yes you can save multiple presets
@HiFi Vector are the setting transferable between phones?
Not sure on that. I have not tried to pair two phones.
Yes. I installed this app on two phones and the settings are saved in the Expert, that is, you can use ten different phones if you wanted to
I use lr12 for mids and highs and bt for bass
When you show the individual channel EQ, there is an F1, F2, and F3. I understand what you are saying when adjusting the F1 but what are F2 and F3?
Also, is delay the same thing as what is labeled as time alignment on other DSP's?
This DSP has 3 customizable frequency numbers per channel. This the f1, f2 and f3. Those are the 3 custom frequencies. This is in addition to the main eQ on the DSP. Yes the delay would be same as time alignment …it will allow you to adjust speakers to “hit your ear” at the same time if you have any need for it.
@HiFiVector I think I get it now. If you had any problem areas, you could zone in on up to 3 specific hz. Otherwise, you can only target the areas listed on the master input EQ.
Does that sound right?
Correct
Thanks.
I'm really exhausted messing with this. I've spent hours trying to get this to work and no luck, sounds horrible. I get the concept of crossovers but they all sound bad and the gain options on this I just can't get right. I feel I'm damaging my system. I'm using a oscope. Whats the point of main in and out gain. I'm one step away just unplugging it
The main purpose of the main input gain is to simply set your input RCA gain. The output channels each have their own gain to fine tune the gain to each output channel RCA. If you are confused just set the output channel gains to all the same value ( say 0 )and then just use your main input gain to control all of the output gains together.
Got a question. I had a Rockford Symmetry epx2 witha 24 band card back in the day. So can you put a y cable on channel one and use that for front highs, one on channel two for front mids, another y on channel three for rear highs, etc. Set the unit at the L+R on each channel in center will it not have to stereo sound that way? And sound weird?The Symmetrys eq was too much but the xovers were awesome and just super control on everything
Yes you can configure it that way. And you would just lose your left and right separation most people would say it’s not too big of a deal but on some songs there is separation that you would miss out on. Also there is another expert DSP with more left and right inputs that might be useful in your situation.
Hey, I have a 12v 1 amp power supply. Should I step up to a 5 or 6 amp or will the 1 amp be enough?
1 amp will be fine.
I just bought this dsp. With my mids HPF amp set, my HU set to HPF off, do I set my amp HPF to off and tune with the dsp?
You should turn off the crossovers on head unit and use the DSP for that.
Hey bro. Have had a chance to use any of the newer DSPs by expert? I'm curious if any are "better" than this one. I see one called x6 air for instance. But hard to get info on the new ones
I haven’t checked out the AIR ones yet.
I have the prv dsp but. No way to tune remotely. Is this better. Than prv dsp ? Thanks 🙏
Yes, I think this one is better in my opinion
Does it have bluetooth input
No this does not
@@HiFiVector another question... How many volts are the outputs
Watch my other Dsp video explains that more in depth
@@HiFiVector ok thanks
I seen the other video and yes many more answers 👍
Can you use one chanel and split it in two with a y jack. Like feed a 2 channel amp out of one chanel from the dsp? Thanks.
Yes you can do that. You would just set the DSP so that one single output is outputting right and left channel through the one output.
Hi, I'm from Guyana. I have the expert 8way jus need to know which is the best expert app to use
Look in the owners manual. I believe the PX8 uses a different app then the PX2
It's not bad for the money I've got one
Good helpful video.
Glad it was helpful!
So bro. For instance, I wish my subs hit the 50-60 Hz range harder. Could I do a low q factor and EQ for 50 53 55, on one output channel and do 57, 59, 61 on another output channel. Then take one channel and plug it in my Left input on amplifier and the other on my Right. And by doing this boost those frequencies? Also I know one EQ will cancel another out. My head unit EQ I cannot turn off. Should I just set it flat? Like my phone EQ I can't turn off either so I set to flat. Thank you for all your help bro
Yea try and keep your head unit EQ flat then adjust with DSP. An easier way is to use a lower Q setting ( wider effected frequency range) so if you set your EQ to boost 55hz with a low Q it will boost 50 to 60. That is the benefit of changing the Q. You can have it effect more of the surrounding frequencies or only pinpoint that one frequency.
@@HiFiVector thank you!
@@HiFiVector I'm sorry to bother you again but the instructions are kind of vague on this thing. My question is each channel output only has one RCA. So does that mean I have to buy a Y cable leaving the DSP? Going into my subwoofer amp I mean because it has left and right input. Or can I use one channel to go into the left and another channel to the right on my sub amp? Which would be the better way if you can do either? thank you. I apologize for bothering you all the time about this but really the instructions are not for a novice
You can do it either way if you’re not using all your outputs you can just used to going to your subwoofer amp. If you wanna use your outputs for something else just use one to the amp with a Y splitter.
I can't get mine to connect threw Bluetooth, it shows the unit as an available device but won't connect to any phone I try. When the app opens it just searchs but won't find the DSP any help would be appreciated
The only thing I can think of is make sure you don’t have any other Bluetooth connected on the phone. That’s the only downfall is on the phone. You can only have one. Bluetooth device activate a time.
@@HiFiVector I've already tried that I even forgot all Bluetooth connections as a shot in the dark.. I'll try the pro version of the app hopefully that does it. Everything works great, except Bluetooth lol main reason I bought it. Thanks for getting back to me ! Subscribed!
Thanks so much man I appreciate that!
can i use only 1pare rca for the input?
Yea
Can you sent me some pics diagram of how to use the crossover or which one
well kinda of disapointed, i have a razor dsp amp that as a analog audio dsp chip in , it givies a 12 band full adjustable eq per channel [Q, FREQ, GAIN] per band this really allows you to shape and correct the sound per speaker, what are you supposed to do with a 3 band??????. . . they really have it back wards, , it should be a 12 band per channel , to shape and correct each spaker and then a 3 band as a eq in to shape the over all sound. . . . I just bought this for a customer project and was hoping it would allow me to tune with a 12 band per speaker like the razor dsp sadly disapointed. . all in all its a great item BUT that fully adjustable 12 band per channel is crucial IF your trying to correct issues. .
Thats Intresting, so you can control the gain of each frequency separately ?
@@kaja9917 yep you pin point the exaxt frequency where ever you want from 20 hz to 20,000 hz as well as the width of adjustement and 20db plus or minus gain. .. And i was wrong its actually 10 bands sorry but still 10 exactly taored bands to your needs
Does this have wide and sweep adjustments like am epicenter? Thank you
Yes. In this DSP you pick the center frequency which ‘sweep” is. Then you change the “Q” which is what width is . The width around the selected frequency.So yes it does just called diggers names.
@@HiFiVector thank you very much!
Hello fam where can I find the best app to connect my dsp too
Just search “ expert “ in App Store.
Hola para un sonido de 6 medios 4 tuiter y un sudwofer lo recomienda
Yes
So my question is how do I get rid of this horrible whining from my DSP I'm grounded to my lithium battery
Rcas are all new and been replaced 3 times already
Change ground location and try that.
Also can't get this dam smart 3 to stop cutting out on me my voltage is strong too my input voltage is 1.89 volts
And I'm not using the DSP for my subs currently but it still cuts out on me then takes a few minutes to kick back on and turning radio off and back on does not turn bass back on however amp stays powered up entire time so it's obviously a protection of some sort I just can't figure it out for the life of me Its only my second full bridge amp first ones I had problems with as well . I'm running #1 welding cable to it from a 60ah a123 bank with stock alt but voltage holds 14s full tilt weird I mean I understand wire capacity but I don't understand how some people are only using 2 agm batteries with 0 gauge wire and there's work phenomenal.
Can i connect 2 eq to this dsp?
This has built in eQ, so no need to use an equalizer separately.
Hey bro. I don't understand the crossover. I'm doing my sub channel. At the bottom it has a number on the left and one on right. Both are adjustable with plus minus. One says hpf and the other lpf. Is the hpf a subsonic?
So in the bottom left set that at like 20 hz or whatever you want yes it’s like the subsonic. The lpf on the right set to 80hz or what you want the upper frequency cutoff you want.
@@HiFiVector thank you. You're the only help in the English speaking world to get help from on this. Do you run one in your setup?
You’re very welcome. Yes
@@HiFiVector bro. How long did it take you to tune this DSP to your liking? Jeez. So many adjustments I can't get it to sound good yet! Lol. I just can't get the subs to sound as good as when I was only running through my head units crossover. Its hitting hard as hell but it's missing certain low notes that it was hitting before. And yes I've played with the 3 band and q factor. Going to continue to do so. Just curious if you might have had this issue also. Thank you for all your help
It didn’t take too long but I did have to go thru and adjust everything to my liking.
Where do you get the app from?
App Store apple or android
my dsp not showing on the app and advise
Turn off all other Bluetooth connections. Also hit the wireless signal logo at the top corner and select the DSP to connect.
Anybody have any advice on getting connected to the Bluetooth I cannot get it to connect to my phone for the life of me also does anybody have any sort of information on customer support on this item I have tried everything I've emailed every single email address that I can find that is associated with this company and have got not one single reply
This vs taramps or prv ? Which one 🤔
Honestly, I believe there are made from the same factory, so it just depends on the features but I think this one still has the most features at the best price
@HiFi Vector I like the bluetooth part and app 👌
How to download the dsp app ?
App Store , search expert Electronics utility
With the Dayton 4x8 only 30 bucks more... No way jose
My sound guy says this is a shit dsp and I should buy a audio control instead but that’s like $800 … he doesn’t want to tune my car with this thing on it . I’m running this in my car right now I don’t know how to use it
Everyone has their own opinion but I know a lot of people who run this for a long time with no issues. I never had any issues with mine either.
i keep getting noice...
Lots of reasons for noise but check rca cables, ground location. Keep rca away from power cables. These usually don’t have a noise issue.
If taken out everything and reinstall.still keep getting noise.
