USB In parameter
The USB In parameter sets the mix level for the audio signal
arriving from a computer via the USB connector.
USB Out parameter
The USB Out parameter sets the output level of the overall
main mix output going to a computer via USB.
Headphone parameter
The Headphone parameter controls headphone volume.
This level is independent of the Analog Out control.
Analog Out parameter
The Analog Out parameter sets the main output level for the
XLR and TRS Left and Right outputs. If you set the Analog Out
parameter to 0 dB and with the input gain set correctly, the out-
puts will deliver approximately the same level as a microphone.
There is 6 dB of additional gain available from this level control
if required. Please be careful when raising the output level as
feedback can occur.
