Extron electronic MPX 866 A manual Muting and Unmuting Video and Audio Outputs

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.

NOTES: • You can mute video-only or audio-only outputs only in a single operation.

• Video and audio can both can be muted, but in separate operations; one and then the other.

• Pressing and releasing the Video button and the Audio button toggles each selection on and off.

• If you select Video and Audio in View-Only mode and then attempt to mute an output, the mute function will not work.

• 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 or S-video planes.

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