A/V Muting

The CTR 8 allows A/V muting for a selected input. This feature allows users to press the selected input button to mute and unmute the audio and video as needed during a presentation.

•Press the button once to select an input (Select state)

•Press the same button again to activate A/V mute (De-select state)

•Press the button once more to return to the Select state, which selects the input and unmutes the audio and video.

NOTE: The A/V mute feature is only triggered by contact closure. SIS input selection (for example, entering 1! two times) will not trigger the de-select state.

A/V Mute Modes

There are three A/V mute modes, based on the device:

•Mute mode 1: Mutes switcher input by selecting channel 0

•Mute mode 2: Mutes video and audio individually

•Mute mode 3: Mutes video and sync

Mute mode 0 is the normal (default) single state operation. A/V mute is not activated in this mode.

NOTE: See the next page for a partial list of Extron switchers that are compatible with the different mute modes.
