Muting and Unmuting Video and Audio Outputs

NOTE: Mutes are protected when front panel Lock mode 2 is selected. You can view

the mute status in Lock mode 2 but you cannot adjust it from the front panel

(see “Setting the Front Panel Locks (Executive Modes)” on page 47).

Individual video and outputs can be muted or unmuted as follows:

1. Press the Esc button to clear any input LEDs, output LEDs, or control LEDs that may be

lit.

2. Press and release the View button.

3. Select video or audio to mute or unmute by pressing the Video button and the Audio

button.

4. One at a time, press and hold the output buttons for the desired outputs for

approximately 2 seconds. The output LEDs 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.
