Muting and unmuting video and/or audio
Individual outputs can be muted or unmuted as follows:
Mutes are protected when front panel lock mode 2 is selected. You can view
the status of the output (muted or unmuted) in lock mode 2 but not change it
from the front panel.
1 . Press the Esc button to clear any input LEDs, output LEDs, or control LEDs
that are lit.
2 . Press and release the View button.
3 . Select video, audio, or both to mute or unmute by pressing the RGBHV
button and/or the Audio button.
4 . One at a time, press and hold the output button(s) for the desired output(s)
for approximately 2 seconds. The output LED(s) for the selected output(s)
blink to indicate the mute or return to their previous state to indicate the
unmute.
5 . Press and release the View button to return to normal switcher operation.
• You can mute video and audio, video-only, or audio-only outputs.
Pressing and releasing the RGBHV button and the Audio button toggles
each selection on and off.
• When you enter View-only mode, the output LEDs turn on for all
outputs without ties.
• The video mute function mutes the R, G, and B planes only; the H and V

• Mutes are saved to non-volatile memory. When power is removed and
restored, the mute settings are retained.
