### 1/5 — It doesn’t let me connect to the DSI-2 on iPhone X

*2019-03-08*

New update for i phone needed ASAP

### 1/5 — App doesn’t work for IOS 12.1.4

*2019-02-20*

I have an iPhone XS Max and I can’t use this app to tune my DSI-2. I tried to connect via an android device and it worked fine. I guess the app needs an update to work with the latest IOS update or something of that sort.

### 3/5 — Help?

*2019-07-15*

Does anyone know if you can use any bluetooth 4.0 usb dongle? instead of buying their overpriced one?

### 5/5 — Great product!!

*2024-10-26*

Has this DSP app on my Harley since it hit the market years ago…Competition level!!! Works very well for me💪

### 5/5 — Five stars amazing product

*2023-08-27*

10 out digitally processed channels with 6 analog input, simple yet very effective. It’s able to  Build a very complex system. Being able to tune all that from your phone, wow. App works great for iPhone 12 and XR. Using this for a portable Bluetooth speaker and to the person asking if you can use some regular Bluetooth adapter, I don’t know but if you use the CORRECT one the unit works great! Overpriced or not, it’s worth it for it to work correctly. Issue with people trying to build a nice sounding system is being cheap. Just my 2 cents.

### 5/5 — DSP tune and Steam music

*2018-08-30*

Awesome app to steam music with Bluetooth 4.0 as well as tuning on the fly via cellphone. Master volume control and more. No head unit needed. Phone, DSI-2, amps to speakers and you are good to go. Easy to learn and use. Huge improvement on audio quality and performance.

### 5/5 — Perfect!

*2018-08-30*

Easy to use, my system sounds awesome now!
