## Description

desertcart.com: B2 Audio Black 4v 10 Channel DSP with Bluetooth iOS/Android App 96 KHz - 32 Bit : Electronics

Review: Great dsp, Great price - Solid dsp. No distortion noticed yet, no popping on start up. Definitely a lot of bang for your buck with this little guy, 6 in 10 out is great. With the app it's simple to configure and pretty straight forward. Hardware wise looks solid but the 12v,S,ground terminal could be a little more solid. "Update: seems cheap due to it being removable, didnt know this at the time" Its nice the bluetooth antenna is removable as I had a extension flat antenna from an old headunit that I ran to the front of my cab, though I probably didn't need to. The app is fine. Works best in landscape but will work in portrait mode, but kinda crams everything together. Only reason I bring it up is my andriod headunit is in portrait mode and that's where I config the app. But worse comes to worse I can use my phone. Toslink in would be a great addition to the next version but rca is fine. A actual manual would be nice The reported voltage is about 1 volt lower than real voltage. Thank you B2, solid DSP you guys have here. Update: Definitely some boom noise randomly when it turns on. Pop. I hate the apps eq setup. Hard to select the frequency with out altering it. Use a s-pen or bring it as all the way down then back up to the level you want. Wish the channel eq could be copied to another channel like the crossover settings. Still happy with the dsp after a few months.
Review: Big Jeff Audio Garbage Treatment and restocking Ripoff - I purchased a B2 DSP box from desertcart and immediately ran into programming issues. I called tech support over a dozen times in one week, and customer service could neither answer basic questions nor reach a technician or installer. This wasted hours of my time. Eventually, a separate A/V professional helped me and discovered one output channel was bad. This was on top of unresolved programming problems—simple things like EQ and crossover settings not saving and constantly resetting—which support never explained how to fix. I returned the unit and was charged a $47 “restocking fee” on a $116 product. They claimed there was a scratch (there wasn’t) and that a small piece of foam was missing. They also stated they found nothing wrong with the unit, which is hard to believe considering they couldn’t even get a tech involved during my week of support calls. There’s no way the bad channel was properly tested upon return. This product and support experience wasted countless hours on my build. I will never use their products again. Way to go, guys. Big Jeff Audio = garbage treatment.

### ⭐ Big Jeff Audio Garbage Treatment and restocking Ripoff

### ⭐⭐⭐⭐⭐ Great easy DSP
*by A***R on November 20, 2025*

This 6 input in and 10 inputs out is amazing and not just for the price. If I upgrade 4 channel amp and add more speakers I’m basically set with this DSP. The app is easy to use but does require for you to enter password every time you connect it. When getting out of the app and returning to the app. It creates white bars on the sides of the app and you can’t see some of the menus on IOS phones. Setting EQ for individual channels, Gain, Delay and crossovers is super easy. Comes with no instructions but just watch some YouTube videos and you’ll see how easy it is. I feel like everyone complaining is just tech challenged, phone challenged or have sausage fingers. There is nothing complicated about this user interface. That there are better options is not the point. Because they also cost a lot more. So for this price point if feels like it’s a steal as long as your not smartphone challenged.
