Mix USB Playback Checkbox — When this box is checked (default), USB Playback
audio is routed into the mix sent to the far end via the USB output.
NOTE:
If using a Web-based soft codec, it may be necessary to uncheck this box,
essentially muting USB playback audio to the far end. Web-based codec audio is
sometimes recognized as playback audio instead of communications audio, and
then creates a feedback loop if sent to the far end.

1
USB — The
USB
panel provides attenuation and mute control for all audio being sent
through the USB output, which includes: USB Playback, HDMI, Line In, and Mic/Line
audio. The
USB
panel also contains output filter and limiter DSP which can be accessed
by selecting the
DSP Icon
. Output DSP functions similar to the DSP on the input
channels (see Input DSP Window on page 53).
2
Line — The
Line
panel provides attenuation and mute control for all audio being
sent through the Line output, which includes: USB Playback, HDMI, Line In, and USB
Comm audio (if selected in the
From Far End
panel of the
Mix
tab). The
Line
panel
also contains output filter and limiter DSP which can be accessed by selecting the
DSP
Icon
. Output DSP functions similar to the DSP on the input channels (see Input DSP
Window on page 53).
3
Reference — The
Reference
panel provides attenuation and mute control for far end
communications audio being sent to the AEC Ref output to an external DSP with AEC.
4
Aux — The
Aux
panel provides attenuation and mute control for Mic/Line audio being
sent to the Aux output for local speech reinforcement or to a hardware video codec.
5
Pink Noise Generator — Each output channel contains a checkbox that activates
a Pink Noise generator that outputs pink noise at a level of -12 dBFS. The signal is
generated at the output stage, pre-processing. Only output DSP is applied to the pink
noise signal.
