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.

This is my second DSP, this is the one to get. Strong signal, no noise, compact, inexpensive, easy to adjust using your phone, inexpensive, several memory slots that you can share, EQ in/out for every channel, delay, crossovers, etc. I could go on and on, it's a budget GEM. Get it!!

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

The BTX8 from Marts Digital is an affordable compact DSP. I struggled to get the app in the Amazon listing to work on my Android device, but Marts Digital sent me a link to the previous app and it works just fine. The unit is so compact that I installed it under the dash. I am using 4 channels in and 4 channels out. The time delay allowed me to center the sound stage. Each output channel has a 31 band EQ that is very flexible There are 6 memory locations for quick uploads of different tunes and a save file function for programming offline. I am a beginner with using a DSP but the BTX8 was straightforward to setup and I am happy with the results.
