Privacy Mute - Master Mute; Group Masters - Extron electronics MediaPort 200 User Manual

Privacy Mute — Master Mute
A master mute control for the microphone mix is located at the Virtual Return A pre‑mixer
gain point, labeled "Privacy Mute." This control mutes the mic mix routed to Output #3,
connected to the MediaPort 200 Mic/Line Input, and ultimately to the far end of a soft codec
conference. This control can be used for privacy during a conference call, to mute the near
end mics going to the far end while still being able to hear the far end.
