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.

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. 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. Thank you B2, solid DSP you guys have here.

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

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.

I highly recommend this DSP. Huge increase in sound quality, has 100% eliminated all of my engine noise as well. The app is pretty easy to navigate and tune the unit. Worth every penny.

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.
