Super powerful
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.

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

Really tuned my system
Oh yes. This is really deal. Sound quality is just awesome. I had used stetsom Bluetooth dsp before this and it sounds terrible. Just alone using this fixes audio quite a bit but remember you have to play with it and your EQ to get it just right. I was having distortion on my sub channel before and this fixes that by letting me cut off certain frequency. And yes you get 4 in 8 out channels 31 bands EQ AND 31 bands parametric EQ per channel. You don’t get 31 parametric EQ in most DSPs at this price range for all 8 channels. Really allow you to dial in. Build quality is also nice . You get shinier front side with clip for left and right channels. Also 8 limiter LEDs that also serve as clip when limiter not used. I’m using this for 4 channel amp and 2 skar evls 12 alongwith pioneer headunit. You also get a sticker with it. Packaging also feels premium. Overall fully satisfied.

Affordable compact DSP
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.
