USB UP CHANNEL SETUP
In addition to playback, the m905’s USB interface allows for up to 10 channels to be transmitted back to
the computer. These ‘up channels’ allow the user to use the m905 as a simple I/O computer interface.
Up channel operation is congured in the PC’s USB Audio Driver Control Panel or Apple OSX Audio
MIDI Setup. Two modes are available. The rst option congures the device for 10 input channels and
2 output playback channels. Input channels 1-2 are derived from the last selected digital input and
input channels 3-10 from the ADAT input. For stereo digital sources, PCM sample rates up to 192kHz are
