With the MIX function you can manually determine which inputs (USB-L/R, Digital-L/R, BT-L/R) will be used for each output (processing channel) and how much of each input the output will receive. The new Music Player function lets you have full control of all your favorite songs, inside the App. Be sure to connect a proper USB device containing audio files in the supported format (MP2/4, WMA, APE, FLAC, AAC, M4A,WAV, AIF, AIFC).
