•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.
