USB DAC

To use the R2 II as a USB DAC, set "USB Mode" to "Audio" in the system settings and connect the device to your computer using the included USB data cable.

Bluetooth Sound Card

Bluetooth Audio → R2 II → USB Audio. Connecting to your smartphone or other devices via Bluetooth audio turns the R2 II into a high-fidelity digital audio source. It supports coaxial digital output or USB audio output, LDAC 96kHz, and UAT up to 192kHz.

Digital Source (WiFi Input)

You can send music to the R2 II via WiFi using DLNA (e.g., BubbleUPnP app) on Android or AirPlay (integrated into the system's slide-up menu) on iOS. The R2 II then becomes a lossless quality digital audio source. It supports coaxial digital output or USB audio output.
