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.
