When the Overview button is selected, the screen displays the following controls for both channels:

input select buttons, HP ﬁ lter indicators, LP ﬁ lter buttons, adjustable frequency settings, input and

output metering, DSP enable and ordering, output level controls, and master linking.

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.
