B50 Amp

The amplifier must be set to BT RX mode using the remote control. Then the connection runs via BT. For me, the device always runs in ARC mode. Sometimes the device does not switch itself on in ARC mode and then I have to help with the remote control. In ARC mode, BT sometimes loses connection. So you can’t make any sound settings on the AMP. But after a few tries it usually works. Otherwise this amp does exactly what I want it to do. I also find the app very self-explanatory and easy to use.
