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.

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

Clean sounding with tons of features
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!!

First dsp it’s great so far!!!
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)
