Muting and Unmuting Outputs
Individual audio or RS-232 outputs can be muted or unmuted as follows:
NOTE: 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) ” ).
1. Press the Esc button to clear any front panel button indications that may be on.
2. Press and release the View button.
3. To select audio, press the Audio button if necessary.
4. One at a time, press and hold the button or buttons for the desired output or outputs
for approximately 2 seconds. The output buttons for the selected outputs 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.
NOTES: • You can mute only audio or RS-232 outputs, not video.
• When you enter View mode, the output buttons light for all outputs
without ties.
• If the audio/RS-232 wire pair of the selected input is defined as RS-232 (see
“ Defining the Audio/RS-232 Wire Pair ”), the serial output is muted.
• Mutes are saved to non-volatile memory. When power is removed and
restored, the mute settings are retained.
