USB button
When the USB button is off (not lit), the XD-2 operates in Rec/Play mode and acts as a standard
USB audio interface for recording and overdubbing. The analog inputs and S/PDIF input are active,
and the DSP modules can be used on these input signals. You can monitor both the direct and USB
playback by adjusting the front panel MIX knob accordingly.
When the USB button is on (lit), the XD-2 operates in "USB processing" mode. The DSP gets its
input from the host computer via the USB port. The analog and S/PDIF inputs are disabled. You can
listen to the master audio output from Tracktion or your other software application, adjust the DSP
settings and send the output back into your host computer as a stereo mixdown pass. The Monitor
and S/PDIF outputs also carry the same signal coming out of the DSP, so you can listen to the signal
as the DSP parameters are changed (and record externally, if required). See page 62 for more details
about the USB processing mode.
