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

I'm an old school SQ guy(Ppi art, Sounstream, etc.. (Class A/B amps) I just recently installed another SQ system in my Volvo V60. Ground Zero Class D, Dyn Audio componets & coaxial(tweeters disconnected) Image Dynamic 12" sub sealed, NVX LOC 44 and this DSP! First if you have a SQ/High resolution setup? I was suprised by just installing the DSP no adjustments yet, my system definately picked up some additional air in the sound stage! Suprised❗️This DSP is a must in a high quality system!! Here is the good.. 32/96 processing for this price range, BT with external antenna, absolutely ZERO NOISE not added to my system. Strong output voltage (based on gain settings on my amp) small device = easy install/ hook up! All aluminum housing! The amount of adjustments on this DSP is fabulous & over whelming at times. You could play all day adjusting your system. The app is easy to install. B2, you need to include better directions or at least a veey detailed user video! There is a video on youtube that is great to use from KJ/ATCJ watch before you start trying to program you DSP!!! As you can tell I am amazed how far car audio has come! This DSP for the price is my best purchase and addition to this system for sure❗️You will not be disappointed with this addition to your system. Thanks B2 for a fantastic car audio componet!

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.

I purchased a B2 DSP box from Amazon 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.

First off - this thing does do what it advertises - I'll give it that. I used this to take two channels of output from my factory radio, tri-amp my front stage w/o using the passive crossovers, and feed my subwoofer amp. After figuring out how the app worked - this was simple. I was able to setup my crossovers, channel mixing and time delay without issue. The app though is an exercise in frustration. It constantly disconnects without telling you. It will often freeze after entering the password (which has to be done EVERY time). The app completely ruins the experience here. It worked better with my Pixel 9, but I could not get it to connect ever to a newer Samsung 10" tablet. I don't have iOS devices to test. Noise level - I had zero noise on my bench, but I have an audible hiss at all times from my highs in-car no matter the source. This could be my car, it's a PHEV so may be interference.... It's very minor, and I'm sensitive, so not blaming the DSP, but I do suspect it (previous 5 channel amp with no DSP did not add hiss).... Quality wise - the box feels built well, it's super tiny and lightweight. I do wish the power/gnd/rem connector was "something else". It's a bit wonky for what feels to be an otherwise decent product. I'd love to see an updated firmware/app that will deal with the connectivity issues and this will easily make this a 5 star item. Overall in terms of bang for the buck - it's definitely got that nailed.

I returned the expert px2 and swapped to this one. The expert px2 had a white noise and pop when turning off. This unit is perfect, no issues regarding noise or pop. You will have to plan for some time to familiarize yourself with this dsp. The bluetooth is great as you can also stream music through this. I'd watch some videos, so your ready. I don't think you can beat this dsp for the money. Not sure of any others that also stream music close to this price It takes some tinkering and patience but it's well worth it. I'm very happy with this. I'm using my phone as the head unit for a classic car setup and this dsp has great gain control to get you where you need to be. I'm using the bluetooth and or a usbc to rca with the dac in the cord. Everything works perfect.

​If you’re stepping up to a high-power installation, stop looking at "budget" processors and get the B2 Audio SixTwelve. I’m using this to manage a complex setup—two 4-channel amps for my mids/highs and a mono amp for my dual 15s—and the level of control is professional grade. ​The Power of 12 Channels: The biggest advantage of the 612 is the 12 output channels. In a build like mine, having those extra channels means I can run a fully active front stage (separate control for tweeters and mid-drivers) while still having dedicated lines for my rear speakers and subwoofers. Every single channel can be tuned independently. ​Precision Tuning: The 96kHz / 32-bit resolution is no joke. The sound staging you can achieve with the Time Alignment settings is incredible—it literally makes the music sound like it's centered on your dashboard rather than coming from the floor. The 31-band EQ and selectable crossovers (Linkwitz-Riley, Butterworth, etc.) allow you to protect your speakers and get every ounce of performance out of them. ​Mobile App & Connectivity: Being able to tune the system via Bluetooth on an iPhone or Android is a game-changer. You can sit in the driver's seat and make real-time adjustments while listening to your favorite tracks. No more running back and forth to the trunk with a screwdriver or a laptop. ​Pros: ​High Output Voltage: Delivers a clean 4V signal to your amps, which helps keep floor noise low. ​Insane Versatility: 12 channels mean you will almost never "outgrow" this DSP. ​Compact Footprint: For a 12-channel unit, it's surprisingly small and easy to tuck away. ​Input Flexibility: Handles high-level and RCA inputs, perfect if you're keeping a factory head unit. ​Cons: ​Learning Curve: If this is your first DSP, the app has a lot of settings. Take your time and learn the "Crossover" section first so you don't accidentally send bass to your tweeters. ​Overall: This is the brains of my build. It’s the difference between a system that’s just "loud" and a system that sounds like a live concert. ​Since you have an 8-channel DSP mentioned in your setup plans but are looking at the 12-channel B2 Audio, would you like me to help you map out exactly which output channels should go to your 4-channel amps and your mono amp?

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.

This is my first experience with a DSP so I don't feel I'm really qualified to leave a detailed review but I can say as someone using a DSP for the first time it does look intimidating but this is extremely easy to figure out. The software developed in their app for this is awesome. The way this looks and feels is awesome. The price in comparison to other DSP units with the same or similar features is awesome. And so my inexpensive, uneducated opinion of this is exactly that. Its awesome. Lastly if you've never used one of these i guess you can't miss something you've never had but im telling you know it or not you are missing a lot. If you have a very expensive, feature rich head unit with solid, clean preamps and a built in DSP , don't worry about getting this just use your head unit. But if you're rocking a lower budget brand such as BOSS, SoundStream or power acoustik you really should invest some of your hard earned money on this and the time to learn it because you can do so much with this!
