Control – Application #2
Control points are pre‑configured in DSP Configurator. These controls can be adjusted from
the DSP Configurator application, and designed into a control system for end‑user control.
Control points are created from group master controls, which provide a single point of
control, with the ability to adjust soft limits.
Program — Master Volume
A master control for the program mix is located at the input pre‑mixer gain point, labeled
"MP Program L/R." This control will adjust the volume level for program content in the room.
Because the master control is located before the routing to the AEC reference, it will also
affect the level going to the AEC reference so that the reference level will track with the room
listening (volume) level for program content.
Program — Master Mute
A master volume control for the program mix is located at the Input 9 and 10 pre‑mixer gain
points, for input channels "MP Program L/R." This control will mute the program content to
both the local room and the far end
Far End — Master Volume
A master control for the far end audio from MediaPort is located at the input pre‑mixer
gain point, labeled "MP Far End." This control will adjust the volume level for far end audio
reinforced in the local room. Because the master control is located before the routing to the
AEC reference, it will also affect the level going to the AEC reference so that the reference
level will track with the room listening (volume) level for far end audio.
Far End — Master Mute
A master mute control for the "MP Far End" feed is located at the Input 11 pre‑mixer gain
points. This control will mute the MediaPort USB Communications "far end" signal to the
local room.
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.
