Adjusting Volume
To adjust the volume in a call, use the 
 button on the remote control. You can also adjust 
the active microphone volume, or the treble and bass levels for audio out by adjusting 
preferences in User Preferences : Audio
Volume preferences for audio inputs appear with a bar graph audio meter next to the slider. 
The audio meter expands below the slider when you select the slider and press OK on the 
remote control. 
The audio meter displays the level of the transmitted voice. The meter is calibrated in 
decibels (dB) RMS below digital full scale (DFS). The meter is accurate to ± 1 dB.
A level of 0 dB is the maximum. 
Levels below –50 dB are not displayed, and indicate a very quiet or inactive input. 
Typical levels during a call peak around –28 to –22 dB DFS. The AEC (Acoustic Echo 
Canceller) and AGC (Automatic Gain Control) In Avaya 1010/1020 attempt to keep the 
RMS transmit level below –20 dB DFS.
To set the level for your audio input, position someone the same distance from the 
microphone as participants would be in the room during a video conference and have them 
speak at a normal volume. Green bars indicate an acceptable setting at normal speaking 
volume. Yellow bars are acceptable if you are shouting or speaking loudly. Avoid settings 
that produce red bars in the audio meter.
Avaya recommends a volume setting of 5 to 8 for most Avaya Video MicPod 1000 
applications. Avaya recommends a volume setting of 5 to 10 for most Avaya Video Camera 
100 applications. Use the meter to visually verify that the transmit level peaks in the desired 
-28 to -22 dB range.
When the user interface is visible during a call, a volume meter for the active microphone 
appears in the near video image next to the dominant speaker icon.
Muting the Active Microphone
Pressing the mute 
 button on the remote control or Avaya Video MicPod 1000 mutes the 
active microphone. When the near side active microphone is muted in a call, the 
 
symbol appears.
