Muting and unmuting video and/or audio outputs
Individual outputs can be muted or unmuted as follows:
N 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 you cannot change
it from the front panel. See “Setting the front panel Locks ( Executive modes)”
on page 3-44.
1 . Press the Esc button to clear any input button indications, output button
indications, or control button indications that may be on.
2 . Select video or audio only to mute or unmute by pressing the Video
button and/or the Audio button.
3 . Press and release the View 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.
N • Video and audio can both can be muted, but in separate operations; one and
then the other.. Press and release the Video button and the Audio button to
select each for muting or unmuting.
• If you select Video and Audio in View-Only mode and then attempt to mute
an output, the mute function will not work.
• Video can be muted or unmuted on outputs 1 through 12. Audio is not
preset on output 7 through 12, so it cannot be muted or unmuted on those
outputs.
• The audio mute is the same mute function that is available via the DSP
Configurator program. See chapter 5, “Switcher Software”.
• When you enter View-Only mode, the output LEDs turn on for all outputs
without ties.
• In the computer video group, the video mute function mutes the R, G, and B
planes only; the sync (H and V planes) are still active. In the low resolution
video group, the video mute function mutes all composite video and/or
S-video planes.
• Mutes are saved to non-volatile memory. When power is removed and
restored, the mute settings are retained.
