Mute buttons (see figure49 on page97) — Select to separately silence
and unmute the left and right audio channels. If you mute both channels,
audio is completely silent on that input. When one or both channels are muted, one or
two red indicators in the block turn on.

Output Signal Source drop-down box— Use this control to select
the audio source:
• Original — Audio embedded in the original digital (HDMI or DTP)
input passes through the matrix switcher without being de-embedded
and processed within the DSP. All other controls in the digital volume control
become unavailable for selection, because audio is not processed within this block.
• From DSP — Audio is de-embedded and processed within the DSP.
• No Audio — Audio is muted (but no indication of the muting is shown other than
the selection in this box). All other controls in the digital volume control become
unavailable for selection, because audio is not processed within this block.
TIP: If the Output Signal Source is set to Original, the digital audio
embedded in the digital (HDMI or DTP) signal continues to be routed as part of
the digital signal and is output with the video, even for audio breakaway ties.
For video-only ties, select No Audio to prevent embedded audio from being
routed with the video signal.

Expansion inputs-to-virtual-send-bus mixer block (

)
These four mixer blocks (see figure 50 on page 99) are an array of points where the
switcher output, the mic, the virtual bus, and the expansion bus audio can be further mixed
and routed for additional processing. The block provides a way to unmute and mute the
inputs. The mix-points are muted by default. Unmuting effectively mixes the inputs into the
audio outputs at the level set in the mix controls.
The function and indication of the mix-points and the dialog boxes are identical to as
described for the Mic-to-output mixer block, on page 95.
