Audio DefaultVolume

Define the default volume for the speakers. The volume is set to this value when you switch
on or restart the video system. Use the controls on the user interface to change the volume
while it is running. You may also use API commands (xCommand Audio Volume) to change
the volume while the video system is running, and to reset to default value.
Requires user role: ADMIN, INTEGRATOR, USER
Default value: 50
Value space: Integer (0..100)
Range: Select a value between 1 and 100. This corresponds to the dB range from -34.5
dB to 15 dB, in steps of 0.5 dB. If set to 0 the audio is switched off.

Audio Input Microphone [n] EchoControl Mode

n: 2..2
The echo canceller continuously adjusts itself to the audio characteristics of the room, and
compensates for any changes it detects in the audio environment. If the changes in the
audio conditions are significant, the echo canceller may take a second or two to re-adjust.
Requires user role: ADMIN, INTEGRATOR
Default value: On
Value space: Off/On
Off: Turn off the echo control. Recommended if external echo cancellation or playback
equipment is used.
On: Turn on the echo control. Recommended, in general, to prevent the far end from
hearing their own audio. Once selected, echo cancellation is active at all times.
