Installed this in my car using the 12v power wire and ground. Works well, the software is straight forward and easy to use. I have not purchased the Bluetooth adapter, Only complaint is the noise it produces, a hum is audible as soon as the unit is powered on. I have tried changing power and ground locations but nothing will fix it. After a bit of research online, it seems like these units are hit or miss for the hum. I guess I was unlucky and got a bad one. The hum is not terrible, but can be annoying at low volume.

This dsp took my system to a whole new level of clarity. My head unit has some dsp function but this took it to a whole new level. App functions well with the bt dongle lil slow changing between presets but makes tuning alot easier.

This an amazing product especially at the price-point. I'm using it in a home-stereo application and it is dead silent. Having the flexibility to individually configure highpass/lowpass/bandpass filters, eq curves, and delays for each of the eight output channels may be overkill but allows almost endless experimenting. I'll be receiving a calibrated microphone and will be using that along with REW software to check/correct room response. I've set up filters and delays by ear but I'm very impressed so far. I found the software easy to use and very intuitive.

I took care to avoid ground loops in my car audio installation. I used this with a Dayton DAC and some attenuators for physical volume knobs for USB audio input with a tablet. The Bluetooth streaming also sounds good. My biggest complaint is it takes WAY too long to switch presets (via Bluetooth from Android app) and cuts audio while it does it. The good news is, with 8 channel tuning with an added main and sub volume knob, I hardly ever want to change it from my main setting. For the price point I am plenty satisfied. I will update my review if my opinion changes
