This insert describes how to use the video and audio mute functions of the CrossPoint, CrossPoint
Plus, MAV series, and Matrix 50 switcher. Video and audio mutes are new features for those matrix
switchers. The front panel operations and SIS commands detailed in this insert are in addition to
the functions described in those products’ manuals.
Depending on your switcher, the video selection button and LED are labeled either RGBHV or Video.
In this insert, they are referred to as Video, but on switchers that have an RGBHV button and LED,
the function is identical.
