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.

Perfect budget friendly dsp for car and home use high quality sound easy to use i had no problems connecting to the app or installing almost 0 noise level

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

Why did you pick this product vs others?: For $170 this is a ton of functionality in a very small package. If you’re in the market for a DSP but don’t want to shell out $550 for a helix mini this will get you a ton of features for a fraction of the price. Make sure you use the marts digital app to connect with the device, it allows you to actually use it. Time alignment, 31band eq on each speaker and the main channel, etc etc etc it’s so so powerful. AND CHEAP. And small!
