B2 AudioBlack 4v 10 Channel DSP with Bluetooth iOS/Android App 96 KHz - 32 Bit

I use this for my bass and the bass hits very precisely, it's a must to get, giving my bass amp the voltage it needed in the first place. Btw, I'm using it with my bassrestor

I bought this to scratch my "tinker" itch. It does exactly what it says it does. Provides a very clean 4V output, verified with a scope. I almost wish I could use a proper laptop program instead of the janky feeling smartphone app but it does do what it promises. Provides what seems to be very solid crossover options. Very simple to map/sum channels. I haven't even touched the delays or limiter functions but this allowed me to stop chasing unicorns with very expensive DSP amps and instead focus my money on raw, clean power.I'm too happy bumping with the bigger amps this allowed me to fit in my budget to nitpick this thing. It provides a super clean foundation to built the rest of the system from and that makes it worth every penny. I'd buy it again.

Performance wise this is great. However, a few cons:1- no real instructions or help out there. Routing is kinda confusing. Sounds great, just no idea really if they're set properly. This is only my 2nd dsp, upgraded from my prv.2- not thrilled with the bluetooth. Seems to work ok, just a pain having to always login and enter password, every time! Also saving a profile is not great. You actually have to type the profile name each time instead of just clicking on an already saved profile. Yes, eventually your phone will remember after typing the 1st letter or 2, but still, could be simpler.3-dont make the voltage readout on the app your only monitor. Mine seems to be quite inaccurate, reading 14.3 when everywhere else is close to 15.4- the connection block is kinda chintsy. It works, just could and should be better.All that being said, still only took off 1 star. The unit is awesome as is using the app as opposed to the stupid dial on prv. The eq is insane! 31 bands for each channel and awesome to adjust. Really fun, the crossover too. Time alignment is great also. No idea what the noise gate does.Definitely room for improvement, but I'm absolutely keeping it. Only had it installed about a week now. Also the small size is nice, fit in glove compartment. However, does seem to get hot. Fortunately I had a small fan collecting dust I was glad to be able to use.Bottom line, if you're thinking about purchasing a prv or stetsom or nvx, don't. Buy this. For the price you can't go wrong

Build quality is good processing is great the application is ok. The app takes a bit to get used to but once you figure it out it's pretty good. The unit is great, does what it's supposed to and store multiple settings locally. I love being able to change my time with just selecting a different saved tune. When I'm really pushing my system it gets a bit warm but have had no issues so far. For the price I think it would be hard to beat. Highly recommend if you need to tune your aftermarket system or want to upgrade a stock head unit to add anything you want.

Kind of confusing to use but once you get it figured out it’sa nice unit.

It’s OK, too much static hard to function. Too many buttons Bluetooth won’t stay connected unless you connect continuously don’t like that.

Works as described.
