After a thorough review of dsp on the market i ended up going with this one thanks in large part to your video. I have had it for over a week now and it has totally changed the game of my system. I love bein able to run the dsp app straight from my android headunit and then using the dayton immc-6 mic connected to my phone to rta tune my system.

Got this for my wife's car a week ago, this thing is fucking incredible for the $!! So many options for tuning! I almost got the Dayton Audio one, but I read a lot of people were having noise issues with them, not this thing! Anyway, for $170, unreal!?! Got the Audio tool app and a calibrated mic, just haven't had the time to tune it yet but I did go through the app to have a look at the features and wow! Thanks for the video sir!
Having high RCA voltage is very important if you want to keep the gain down on your amplifiers to avoid a high noise floor. Alot of amps with poor signal to noise (manufacturers LOVE to lie about the s/n numbers) need the gain down low or you will hear noise. 4 or 5v is plenty. I've owned DSPS with 2v all the way up to 8v RMS on a helix DSP ultra and i can say that if you have a solid 4v or higher it is sufficient for the vast majority of applications.
I just got one at Big Jeffs says I'll get it on Saturday it's back in stock . Everywhere else still says out of stock I need to know which microphone to get Dayton it's got three or four of those microphones does it have to be USB or can it just pop into your microphone on your Android@MJIsrael-z3y
The benefit of having high voltage output on car amplifiers for RCA connections primarily revolves around improved noise rejection and reduced stress on the amplifier. High voltage preamp outputs allow for a reduction in the gain required by the amplifier, which in turn reduces the potential for noise in the system. This is because a higher input voltage to the amplifier means that the amplifier does not have to work as hard to amplify the signal to the desired level, leading to less distortion and a clearer sound

@derekgardin1512 good idea. Unfortunately for me, my stock head unit can't be swapped, so I use a LC2i Pro. I could pull the harness plug to the head unit though.
Most head units send a 1 - 3 volt signal whereas an LOC will send a 5 - 7 volt sugnal. This really does allow your amp to run cooler, and last longer plus sound better. Otherwise just get an integrated amp. DSP's are still a good thing if you have enough channels. I like running 3 way systems so yeah that can be a challenge with 12 speakers in the cabin. Though there are some good coaxial speakers as well if you don't have a setup for component speakers in your car.

Yes call Big Jeff immediately they're back in stock I got one on order and supposed to be in Texas Saturday. I don't show anybody else anywhere that got them back in stock except for them
HOLY SHIT BALLS. FINALLY a cheap dsp that’s 4 in 8 out. I’m so sick of these 2 in 8 outs. I’m going to give this a try. I’ve wanted to get the Dayton dsp for the longest time but I’ve just been put off by the years of reviews mentioning noise.
I do know one thing if you're playing music through your Android make sure you turned Atmos equalizer in all settings keep it flat and keep it flat on your head unit.
I too have a 2013 Nissan Armada platinum but I’m curious if you have the big 3 done on your’s, & if so what did you do about the “RVC” “VVCS” on the stock neg battery cable!? Did you by-pass it or was you able to get a 1/0 through there! I’ve searched forums and everything but can’t find a definitive answer! It look like I could only fit a 4 gauge thru it but I plan to get a HO alt later so will have to upgrade a figure it out the 1/0 later anyway! Anything helps thanks bro and keep up the good work!🫡💪🏼💯 Also I just picked up the stetsom bt dsp! I seen your review after I purchased it!
Hello,looks like i am to late to buy this DPS.Big Jeff An Amazon doesn't carry the BTx8 anymore.Can you suggest an equal replacement. I like your channel alot.
I have a Bronco w/non BO system, and I'm thinking of switching from the kicker key 200 dsp to this dsp ..plus upgrading the fronts to a 3 way setup. Do I need anything between this dsp and oem HU like the AC load generator or an Loc? I plan on getting a more powerful amp that has at least 100w x4 @4ohm to power fronts only,.. OR a 6 channel amp to power all speakers instead of the kicker.
Quick Question - In the App while setting the Input Signal Equaliser "EQ IN", does it show the input signal frequency spectrum? How do we know what EQ corrections the input signal requires?
Ok my question is how can you accurately set the time alignment. Since it's in milliseconds and not feet or meters seems like a pia. I'll be running tweet, mid, mid bass up front. Probably gonna split channel 7 for rear fill and use 8 for subs. My tweets and mids are going to be on axis mid bass in the doors.
Good timing. Been looking for a DSP and definitely budget minded. I had been looking at the Dayton Audio DSP408 but it had mixed reviews and is twice as much as this one (after buying the bluetooth adapter that it does not include) in the review. Does this accept speaker level inputs? I hear that a dedicated LOC is best even with the ones that do but its still a nice feature. May have to order one today
Yea I would use a standalone low level converter they are cheap nowadays. Sadly the Dayton was one I tested and when I eventually tested it it was totally dirty on the signal and I could not get it clean…didn’t even get .5 volts out of it clean. Maybe I got a bad one who knows. But this is a good one for sure.
I just ordered one from Big Jeff's they're back in stock. I don't know what it's going to do for me in a new Ford Maverick pickup. I'll only use four channels channels two for front what does a JBL aapex 1502 amp that's 100 watts per Channel that's going to go does 6 1/2 in GTO 629 jbl's in the door also JBL tweeters in the back. For the back will be a Stinger 1000 w @ 1ohm. To a Sundown classic 10-inch in a sealed box with 0.6 cubic foot. So I'm going to run two sets of tweeters and those six and a half JBL coaxials all off of one amp. So I don't know if this is going to do me a whole lot of good
You can’t “see” what’s coming in as far as wavelength or frequency or roll off. You can only see that for the adjustments you make in the DSP for the output.
So if I have a total of 5 speakers 4 coaxial speakers on a 4 channel amplifier and 1 subwoofer on a monoblock amplifier would this work or can I get away with using a 6 channel DSP?
Does it produce any rf noise when it is installed in a 12V system? Bench testing is great and all but Im more interested in what it will do in its natural enviornment.
Been using it for a few days now. It has full balanced input & output (unlike the dayton audio). So, as long as you use quality RCAs you won't have noise.
@@r.d.1056 Thanks. I have a DSR1 but I find that it is unreliable connecting via bluetooth. I was looking at the Dayton until I saw the reviews stating that noise was an issue. Will have to give this a closer look.
@almartinelli5054 the Dsr1 is a better unit than this one. Are you streaming directly to the Dsr1? If not, there's no reason to be constantly connecting to it. Once tuned it should be a set it & forget it type of thing.
@@r.d.1056 Havent had it long so Im still experimenting with it. I was having some issues with rf noise which i found to be the input plug was not plugged in all the way. I dont stream via bluetooth as I can do that from the head unit if I wish, I use the USB input for most of my music. It is a set it and forget it but at times I find, especially with mp3, that everything seems to be recorded at different levels so I find myself adjusting the input eq more often than not. I was just curious as to whether the settings were more or less advanced than the DSR1. Overall its been a good unit so far but always looking for something better.
I just put in my Expert X8 DSP today, everything went awesome until I went to start the car, ALT WHINE UP THE YIN YANG! What gives? RCAs str8 to amp, and i have no noise. Ooooh its annoying as hell, the DSP seems pretty sweet minus the whine.
@@408SPLKINGS I got it narrowed down to my rear left RCA cable coming into the DSP,, just that one wire is whats giving me buzz/whine. Still no buzz when direct to amp. I must also add my RCA connections are coming from a crux GM/Bose system integration unit converting from the speaker outs of my new HU. I suppose ill have to crack back into my dash and see whats going on, maybe some cable mgmt or something like that.
@@408SPLKINGS I think i made a rookie mistake when I mounted the amp against the trucks sheet metal, was slightly bigger than the stock amp. Im gonna correct that and insulate the mount points. Ive also picked up a capacitor for good measure, they've helped filter noise out before for me and I need to make the stock alternator last too, lol
Get some of those cone shaped rubber stoppers from home depot/Lowe's and use those to decouple your amp from sheet metal 👍 they are like 50 cents each @@AllboroLCD

Bought this DSP after watching this video. Yes you can use Bluetooth as the source although it doesn’t sound quite as good as when I play music from the headunit
I'm curious what source unit he used (and it's pre-out voltage). Does this DSP ultimately convert everything to 4.5 volts no matter how strong or weak the input signal is? I already bought one, replacing my Expert Air8.
Would you switch from a Taramps dsp2.4 to this one? I wonder how clean the rca volts are on the Taramps dsp lol. My Taramps highs setup is running off of an Audio Control LC1i wired to a factory dodge 8.4in uconnect.
Yes. I just switched & it sounds better, it has balanced inputs so ZERO noise! The dayton has pitiful input sensitivity, this one can take a full 4+ volts & has much higher output voltage, so you need less gain on the amps. It has a master input gain & input EQ, the dayton does not. I like the time alignment settings better on this one. It has a few quirks. You have to make sure to save any changes because it won't auto save like the dayton. Also, you can't label the channels or presets, or at least I haven't figured it out yet. And you have to connect to it manually each time. So far I like it better & I think it sounds better.
So I got the DSP and I cannot get the application to work it keeps freezing every time you go to the equalizer and or equalizer on each Channel it just shuts off. Android app does not work!
@@HiFiVector I have that one also and it does the exact same thing. They are both version 1.2.7 at this point I have my gains and my crossover set but I cannot get to the eqs. So basically my system is not complete. I had the Expert audio line I purchaded off of your review also and that has been working fine for me. I really want to try this one but you can't adjust the eqs unless I get an iPhone apparently.
Are there instructions for this dsp? I installed one in my suv but it’s not saving my settings when I turn the car off. Also if I switch to a different memory setting, memory 1 no longer has my settings.
If I like a product I’m honest about it and I just really like this DSP that’s why I was kinda pumped on it. I bought it a while ago so I had time to use it and check it out in my truck for a while before the video.
@@jasonerosewrxgo back and read what big Jeff audio says he tells you what you need to do... All you need to do is give your device permission to download the APK it's very easy
Hey HiFi I just ordered this DSP from big jeff audio it's actually my first EVER DSP i have a DD-1 and CC-1 but when I used them with my stock head unit and LOC i couldn't get them to work properly I was told my signal was not strong enough so I ordered this DSP, Head unit and a ton of other stuff im redoing my entire system to get ready for a down 4 sound HD3 single 15 enclosure and a new 15" Incriminator audio TYRANT rated for 5K RMS but I have a brand new Deafbonce AAK 6k and a AAK 180.4 for the doors anyways with all this new equipment i am wondering if you can recommend a decent oscilloscope for a decent price so I can try again with the SMD tools and cross check with the oscilloscope I am trying to get into competitive audio and I don't want anything to mess up from a clipped signal and I already almost blew two subs trying to tune by ear so I want multiple ways to check it just to make sure for next time
@@HiFiVector thank you very very much for responding I need all the help I can get I've been trying to post videos asking for help but I'm still waiting on some stuff to come in but again thank you I'm really trying to get into competitive audio and it's taken me over a year so far and I have so much work to do and anything that makes it easier I'm all for it
@HiFiVector can I use this for jp83 sub amp if so.How to set cross over on amp or is it better for mid and highs amp? Thanks for all the info you give really helps out a lot.I bought 1 and I'm loving it.learning how to use it is very easy. Happy birthday with dsp!!!
Does this thing have a subsonic filter? If so how do you use it? Also is there another name for a subsonic filter because it's hard to find a crossover or DSP with one. Thanks in advance.
Subsonic filter Is just a low frequency cutoff which is same as going into the crossover and let’s say it’s for a subwoofer… so you want to hear from 20hz to 80hz you just set your crossover setting to start at 20hz and end at 80 hz. That will be in the crossover settings on the DSP. It will output all frequencies in between those two numbers. And for tweeters let say 5. Start and 20,000 end etc….
Where do you download the app? Where can I get a manual.pdf? Their website is in serious need of attentiion... don't even see a BTX8 listed as a product or support. I picked up two at that price point, but would like to see the DSP software
Can you run this DSP without A? Headed unit just straight from the DSp or you have to have a head unit to run this DSP ? Trying to put one on my little Mini. Bike
Qre the dsp settings you're adjusting on your phone also stored in the dsp that way i can set it and forget it or do i need to have constant connection between my phone and dsp for that to work?
@tctbs1327 please elaborate. I don't understand what you are saying. I've Ben testing this device extensively. Once the settings are saved, there is no need to connect to it unless you want to make changes. My only gripe so far is that you can't label the channels or presets.
@marquetterichardson6529 from the home screen go to preservation, click on one of the numbered preset buttons, then click save. It will save the settings as you currently have them.
I just ordered the Expert x8air 8 channel dsp . Which looks to be identical except for the outer shell. App is exact , just different colors. Anyway , I'm currently running a Kenwood head unit , soon to be a joying 12 " with insane dsp and Dolby theater 5.1 sound. Being as both have really good sub channel adjustments, do you think running sub channel from the head unit to the amp ( smart 3 bass ) would be fine ? And free up channels on the dsp. Anyone run their system this way.. I'm new to the dsp is why I ask. Thanks in advance
Yea I have both and I like both But I get more clean output voltage on the marts than the expert. Yes I think a sub needs less adjustment than the mids and tweets so if you wanted to save a channel from the DSP and just go directly from the head unit to the sub amp, that would be fine.
They're back in stock this week at Big Jeff's I got one and it's coming on Saturday. I ordered it November 3rd 2024. A few days before I was looking through their site and it said they were out and said if you want to be on their email list when this item gets back in stock to subscribe and I did two days later I got a deal says it's back in stock LOL and nobody else including Amazon has it right now
Except 1 Problem: Using RCA connections on a DSP defeats the purpose. You need a Toslink connection into your amp to continue the digital Signal. DSP - Digital Signal Processor. RCA is analog connections. The problem only 3 amps I know of have Toslink Input: JL Audio, AudioControl, Helix. There may be others but they will certainly be the high end amplifiers. 99.9% of car amps have RCA or speaker level input. What to do? Buy an Integrated amp with DSP included! OR Get either a Kicker or Recoil or AudioControl Line Output Converter (only 3 brands I know that work as advertised). They will clean your signal, and boost the signal to your amp so it sounds better, works less, and runs cooler. Best $25 you can spend on your stereo. Nothing against stand alone DSP's except they seem to defeat the purpose going Analog/Digital/Analog with the signal from the head unit. I think LOC's can provide very good boost to your signal and then just adjust the gain, and high and low pass filters on your amp. With such short wiring lengths you can still get very good SQ with an Analog signal. Especially if you don't skimp on the size of your wire!
You are incorrect. It’s beneficial at times to have a digital input on the DSP, not the amp. The DSP converts digital to analog and the amp produces sound via analog.

I don't show anybody else anywhere that got them back in stock except for them
Thank you.
HOLY SHIT BALLS. FINALLY a cheap dsp that’s 4 in 8 out. I’m so sick of these 2 in 8 outs. I’m going to give this a try. I’ve wanted to get the Dayton dsp for the longest time but I’ve just been put off by the years of reviews mentioning noise.
For factory integration would it be best to run something like a keyloc into this or will a simple LOC be sufficient?
Loc will be fine
I do know one thing if you're playing music through your Android make sure you turned Atmos equalizer in all settings keep it flat and keep it flat on your head unit.
this thing is awesome
Recoil makes a great one and it’s only $20. Amp gain is turned all the way down and bass boost is off. Slamming now
I too have a 2013 Nissan Armada platinum but I’m curious if you have the big 3 done on your’s, & if so what did you do about the “RVC” “VVCS” on the stock neg battery cable!? Did you by-pass it or was you able to get a 1/0 through there! I’ve searched forums and everything but can’t find a definitive answer! It look like I could only fit a 4 gauge thru it but I plan to get a HO alt later so will have to upgrade a figure it out the 1/0 later anyway! Anything helps thanks bro and keep up the good work!🫡💪🏼💯 Also I just picked up the stetsom bt dsp! I seen your review after I purchased it!
Is there a knob for volume and bass?
No
Hello,looks like i am to late to buy this DPS.Big Jeff An Amazon doesn't carry the BTx8 anymore.Can you suggest an equal replacement. I like your channel alot.
So, how does thing compare to the AudioControl DM608 voltage/signal wise?
I have a Bronco w/non BO system, and I'm thinking of switching from the kicker key 200 dsp to this dsp ..plus upgrading the fronts to a 3 way setup. Do I need anything between this dsp and oem HU like the AC load generator or an Loc? I plan on getting a more powerful amp that has at least 100w x4 @4ohm to power fronts only,.. OR a 6 channel amp to power all speakers instead of the kicker.
Is this capable of making adjustments below 20hz? What is the max time delay between channels? Thanks
Quick Question - In the App while setting the Input Signal Equaliser "EQ IN", does it show the input signal frequency spectrum? How do we know what EQ corrections the input signal requires?
@hifivector, how do you like this one vs that new bt audiopipe you just reviewed?
When are these gonna be available again?
I downloaded the app for android and it seems mine limits the HPF at 500hz. Does yours do that?
Is this better that the expert electronic x8 dsp
Is possible renames the inputs or outputs
Ok my question is how can you accurately set the time alignment. Since it's in milliseconds and not feet or meters seems like a pia. I'll be running tweet, mid, mid bass up front. Probably gonna split channel 7 for rear fill and use 8 for subs. My tweets and mids are going to be on axis mid bass in the doors.
Use measuring tape. You input the inches and it’ll do the conversion for you
This is identical to my ds18 dsp4.8bt. love the thing need more info on how to set up the limiters. Help
Looks similar but they are not same I tried that one you mentioned as well and this is a better DSP.
How do you connect to a C7 Corvette with Bose AMP?
Good timing. Been looking for a DSP and definitely budget minded. I had been looking at the Dayton Audio DSP408 but it had mixed reviews and is twice as much as this one (after buying the bluetooth adapter that it does not include) in the review. Does this accept speaker level inputs? I hear that a dedicated LOC is best even with the ones that do but its still a nice feature. May have to order one today
Yea I would use a standalone low level converter they are cheap nowadays. Sadly the Dayton was one I tested and when I eventually tested it it was totally dirty on the signal and I could not get it clean…didn’t even get .5 volts out of it clean. Maybe I got a bad one who knows. But this is a good one for sure.
@@HiFiVectorcould you put Amazon affiliate link i see they sell it also. I wouldn't give big Jeff audio 1c of my money.
Holy cow 4.6v unclipped. I just ordered one to replace my Dayton with the bluetooth and remote. Thank you. Now just need a LOC. :)
What did Jeff do to make you feel that way?
@PeterFeltersnatch852 big Jeff has exclusivity on all online sales of Marts Digital products in the US
I just ordered one from Big Jeff's they're back in stock.
I don't know what it's going to do for me in a new Ford Maverick pickup. I'll only use four channels channels two for front what does a JBL aapex 1502 amp that's 100 watts per Channel that's going to go does 6 1/2 in GTO 629 jbl's in the door also JBL tweeters in the back.
For the back will be a Stinger 1000 w @ 1ohm. To a Sundown classic 10-inch in a sealed box with 0.6 cubic foot. So I'm going to run two sets of tweeters and those six and a half JBL coaxials all off of one amp. So I don't know if this is going to do me a whole lot of good
Can you see in the app the signal coming in so that you know what to adjust? Can you see for example if there’s bass rolloff or not?
You can’t “see” what’s coming in as far as wavelength or frequency or roll off. You can only see that for the adjustments you make in the DSP for the output.
@@HiFiVector Thank you
Great review, is airplus8 still available, can't find it.
Yes its called “Airplus” in the app store
I have 6 amps in my truck. 5 for mids and tweeters and 1 for subs. Can i feed all 6 with this dsp?
Just depends how yo program it. A lot of options.
Can the zen a2b interface be ran to this marts DSP
So if I have a total of 5 speakers 4 coaxial speakers on a 4 channel amplifier and 1 subwoofer on a monoblock amplifier would this work or can I get away with using a 6 channel DSP?
Yes this will work
Does it produce any rf noise when it is installed in a 12V system? Bench testing is great and all but Im more interested in what it will do in its natural enviornment.
No noise I had this installed for. Few weeks to test prior to the video as I bought it last November so I had messed with it a lot beforehand.
Been using it for a few days now. It has full balanced input & output (unlike the dayton audio). So, as long as you use quality RCAs you won't have noise.
@@r.d.1056 Thanks. I have a DSR1 but I find that it is unreliable connecting via bluetooth. I was looking at the Dayton until I saw the reviews stating that noise was an issue. Will have to give this a closer look.
@almartinelli5054 the Dsr1 is a better unit than this one. Are you streaming directly to the Dsr1? If not, there's no reason to be constantly connecting to it. Once tuned it should be a set it & forget it type of thing.
@@r.d.1056 Havent had it long so Im still experimenting with it. I was having some issues with rf noise which i found to be the input plug was not plugged in all the way. I dont stream via bluetooth as I can do that from the head unit if I wish, I use the USB input for most of my music. It is a set it and forget it but at times I find, especially with mp3, that everything seems to be recorded at different levels so I find myself adjusting the input eq more often than not. I was just curious as to whether the settings were more or less advanced than the DSR1. Overall its been a good unit so far but always looking for something better.
I just put in my Expert X8 DSP today, everything went awesome until I went to start the car, ALT WHINE UP THE YIN YANG! What gives? RCAs str8 to amp, and i have no noise. Ooooh its annoying as hell, the DSP seems pretty sweet minus the whine.
99% it's a bad piss poor ground
do NOT trust or rely on oem factory grounds....
@@408SPLKINGS I got it narrowed down to my rear left RCA cable coming into the DSP,, just that one wire is whats giving me buzz/whine. Still no buzz when direct to amp. I must also add my RCA connections are coming from a crux GM/Bose system integration unit converting from the speaker outs of my new HU. I suppose ill have to crack back into my dash and see whats going on, maybe some cable mgmt or something like that.
@@408SPLKINGS I think i made a rookie mistake when I mounted the amp against the trucks sheet metal, was slightly bigger than the stock amp. Im gonna correct that and insulate the mount points. Ive also picked up a capacitor for good measure, they've helped filter noise out before for me and I need to make the stock alternator last too, lol
Get some of those cone shaped rubber stoppers from home depot/Lowe's and use those to decouple your amp from sheet metal 👍 they are like 50 cents each @@AllboroLCD
Any idea why the android download don't work I got android so this is worthless if I can't use my galaxy fold 3 to tune the dsp

can you use the bluetooth as the music source so i do not need a head unit?
Bought this DSP after watching this video. Yes you can use Bluetooth as the source although it doesn’t sound quite as good as when I play music from the headunit
I'm curious what source unit he used (and it's pre-out voltage). Does this DSP ultimately convert everything to 4.5 volts no matter how strong or weak the input signal is? I already bought one, replacing my Expert Air8.
Was there a difference between the expert air 8 and this one. They look the same except this on is out of stock and expert is in stock.
Hey vector can you do the same output check on the TIMPANO DSP
Sorry man I don’t have that timpano here to test.
do i have to connect via bluetooth every time i'm in my car or just when i want to change the settings?
Just when you want to change settings.
It's available, but they clearly raised the price to $160, makes it less attractive. Still worth it? Provided expert x8air is around $110.
Does this have more clean voltage than the Dayton 8channel dsp?
From the Dayton I tested yes this Mary’s has more output voltage. Maybe I got a bad Dayton but I could not get a good signal out of the one I tested.
Do Martz make a DSP with high level inputs? If not what's a good budget line converter?
I don’t think they do but here are a couple good low cost high to low converters

@@HiFiVector thanks! Do you have any issues with the recoils 10v RCA output? Seems like a lot of voltage for some amps to handle?
Would you switch from a Taramps dsp2.4 to this one? I wonder how clean the rca volts are on the Taramps dsp lol. My Taramps highs setup is running off of an Audio Control LC1i wired to a factory dodge 8.4in uconnect.
Actual have not tried the taramps yet.
Is it better than the Dayton 4x8 for sound quality?
Good question. I'd like to know too
I have the dayton and this is looking like its replacement …hope it does sound as good
Yes. I just switched & it sounds better, it has balanced inputs so ZERO noise! The dayton has pitiful input sensitivity, this one can take a full 4+ volts & has much higher output voltage, so you need less gain on the amps. It has a master input gain & input EQ, the dayton does not. I like the time alignment settings better on this one.
It has a few quirks. You have to make sure to save any changes because it won't auto save like the dayton. Also, you can't label the channels or presets, or at least I haven't figured it out yet. And you have to connect to it manually each time. So far I like it better & I think it sounds better.
How do you save on this dsp? I thought it auto saved but I keep losing my settings.
@@bigr659 it does not auto save. Save manually and double ckeck.
So I got the DSP and I cannot get the application to work it keeps freezing every time you go to the equalizer and or equalizer on each Channel it just shuts off. Android app does not work!
I found another app that works it’s the same app just different s color. Search for “GS X8 DSP” app.
@@HiFiVector I have that one also and it does the exact same thing. They are both version 1.2.7 at this point I have my gains and my crossover set but I cannot get to the eqs. So basically my system is not complete. I had the Expert audio line I purchaded off of your review also and that has been working fine for me. I really want to try this one but you can't adjust the eqs unless I get an iPhone apparently.
i got it working with an old android 12 phone. smh. I like it though everything louder more powerful.

@@cnitty76 it works I had to try another phone.
Just bought
Any clue what chip this uses?
Can you use speaker level directly into this DSP?
No you need a high to low level converter
Are there instructions for this dsp? I installed one in my suv but it’s not saving my settings when I turn the car off. Also if I switch to a different memory setting, memory 1 no longer has my settings.
Me too if you figure it out can you please let me know been tring to get it to save for 3 days
You can sell tf out of a good product! 👍
He def can... But if the product is good it will sell itself!!
If I like a product I’m honest about it and I just really like this DSP that’s why I was kinda pumped on it. I bought it a while ago so I had time to use it and check it out in my truck for a while before the video.

Does the settings on the dsp overrun the filters on the amp or do i set the amp to full and use the DSP crossover?
As far as crossovers go yes set crossovers to full on amp and use DSP to control crossovers settings.
@HiFiVector can I use this for jp83 sub amp if so.How to set cross over on amp or is it better for mid and highs amp? Thanks for all the info you give really helps out a lot.I bought 1 and I'm loving it.learning how to use it is very easy. Happy birthday with dsp!!!
does anyone know what the max charging voltage is on it?cant find it anywhere online.
Charging voltage?
Does this thing have a subsonic filter? If so how do you use it? Also is there another name for a subsonic filter because it's hard to find a crossover or DSP with one. Thanks in advance.
Subsonic filter Is just a low frequency cutoff which is same as going into the crossover and let’s say it’s for a subwoofer… so you want to hear from 20hz to 80hz you just set your crossover setting to start at 20hz and end at 80 hz. That will be in the crossover settings on the DSP. It will output all frequencies in between those two numbers. And for tweeters let say 5. Start and 20,000 end etc….

Yes that’s usual where you start at flat on head unit then EQ with DSP.

@@HiFiVectorfollow to the question, how do i set my amplifier settings if the dsp has all of the eq and crossovers already set?
Qre the dsp settings you're adjusting on your phone also stored in the dsp that way i can set it and forget it or do i need to have constant connection between my phone and dsp for that to work?
I’d like to know the answer too.
Once you save the settings, they're stored in the device.
@tctbs1327 please elaborate. I don't understand what you are saying. I've Ben testing this device extensively. Once the settings are saved, there is no need to connect to it unless you want to make changes. My only gripe so far is that you can't label the channels or presets.

no Hi level inputs?
I use an audio control active LOC for that.
I just ordered the Expert x8air 8 channel dsp . Which looks to be identical except for the outer shell. App is exact , just different colors. Anyway , I'm currently running a Kenwood head unit , soon to be a joying 12 " with insane dsp and Dolby theater 5.1 sound. Being as both have really good sub channel adjustments, do you think running sub channel from the head unit to the amp ( smart 3 bass ) would be fine ? And free up channels on the dsp. Anyone run their system this way.. I'm new to the dsp is why I ask. Thanks in advance
Yea I have both and I like both
But I get more clean output voltage on the marts than the expert. Yes I think a sub needs less adjustment than the mids and tweets so if you wanted to save a channel from the DSP and just go directly from the head unit to the sub amp, that would be fine.
@HiFiVector I looked for the Marts but no one had one and few that did was wayy to much. Hopefully the x8air is still pretty clean .

Wish it was 6 channel
Except 1 Problem: Using RCA connections on a DSP defeats the purpose. You need a Toslink connection into your amp to continue the digital Signal. DSP - Digital Signal Processor. RCA is analog connections. The problem only 3 amps I know of have Toslink Input: JL Audio, AudioControl, Helix. There may be others but they will certainly be the high end amplifiers. 99.9% of car amps have RCA or speaker level input. What to do? Buy an Integrated amp with DSP included! OR Get either a Kicker or Recoil or AudioControl Line Output Converter (only 3 brands I know that work as advertised). They will clean your signal, and boost the signal to your amp so it sounds better, works less, and runs cooler. Best $25 you can spend on your stereo. Nothing against stand alone DSP's except they seem to defeat the purpose going Analog/Digital/Analog with the signal from the head unit. I think LOC's can provide very good boost to your signal and then just adjust the gain, and high and low pass filters on your amp. With such short wiring lengths you can still get very good SQ with an Analog signal. Especially if you don't skimp on the size of your wire!
You are incorrect. It’s beneficial at times to have a digital input on the DSP, not the amp. The DSP converts digital to analog and the amp produces sound via analog.
