Marts Digital 8 Channel Output 32Bits 96KHz Bluetooth DSP BTX8-DSP

This DSP performs very well. It has a 32-band graphic equalizer for the main inputs (4) and a 16-band parametric equalizer for each output (8) for each speaker. Think about the amount of control you can have. 1- I matched my voltage for the outputs and inputs correctly. 2- I did the crossover cuts. 3- I flat-eq the system with a little bump in the low frequencies. The results were truly remarkable, with the system delivering an incredible sound. 4- I could tweak every speaker to my liking, and the result was phenomenal. One more thing: It produced almost 5 volts out with no distortion whatsoever, and my amps are running super cool. My sub gain is set at about 11 o'clock, and my front/rear at 9. Even if you are off a budget, I recommend this unit. The Bluetooth connects super fast, the app is very user-friendly, and it has a limiter, master gain, channel gain, time corrections, you name it. This is a super unit. It is 100% recommended.

This is AMAZING, small but mighty. I was able to tune all my amps including the base. Love it.

I'm using this with the AEDIKO "AC to DC Isolated Power Supply Module 110-245V to 12V Power Supply Module 12V 6A 70W Isolation Power Module with Overvoltage Overload Short-Circuit Protection" to DSP my theater subs. I'm feeding the sub outs (2 for now) from my Anthem MRX1140 to this device and then sending it to a Crown XLS2002 amplifier. It's wild that you get 4 ins ( labeled a,b,c,d for some reason) and 8 outputs ( Labeled 1,2,3,4,5,6,7,8) I'll amend my review if this product doesn't last a year but for now I'm stoked. **Note, Had to download the app from the website (qr code in the box) which required turning off auto blocker. Turned it back on once the download was completed.

The app literally does not work. I think the app itself is a fake Chinese one. If you download the official marts digital app it works although it disconnects pretty often. But once u do end up getting actual app to work this thing is pretty good for the price. Changed my sound system for sure

My first dsp and I love it so far!!! Once you get used to the app the tuning is amazing!!! Sound good no noise it’s easy to install and for the Bluetooth part that every one it asking yes it does Bluetooth for tuning and streaming music you just have to put the Bluetooth input in the channel routing on only thing I don’t like is to my knowledge it doesn’t state why Bluetooth it has but the Bluetooth does work and the turning is great!! But the lack on information for the product is what I don’t like I put mine on a cooler build I’ll put some pictures (not done yet)
