4.5.5 Audio Levelling (AGC)
On
Select On to allow automatic adjustments (Automatic Gain Control) of audio
levels. When On, the AGC maintains the audio signal level at a fixed value by
attenuating strong signals and amplifying weak signals. Very weak signals, i.e.
noise alone, will not be amplified.
Off
Audio levelling is not activated.
Note that to ensure correct behaviour of the AGC, it is crucial that the levels on the input
connectors are adjusted correctly using the audio input level settings. The AGC will not
compensate for severe maladjustment of input levels.
When applying a weak signal in the presence of strong background noise, the AGC might
amplify the background noise as well as the signal. Therefore, in noisy environments, it is
advisable to turn the AGC off.
Example:
In most conferences, the participants will speak at different levels, and be at different
distances from the microphones. As a result, some of the participants would be harder to
hear than others. The AGC corrects this problem by automatically increasing the
microphone levels when "quiet" or "distant" people speak, and by decreasing the
microphone levels when "louder" people speak.
4.5.6 Alert Tones and Volume
Video Call Alert Tone and Telephone Alert Tone
To help distinguish between incoming video calls and ordinary telephone calls, it is
recommended to use different ringing tones for video calls and telephone calls.
Alert Volume
You may change the volume level for the selected ringing tone.
Alert Speaker
The system also has an internal, call-alerting speaker.
On
The internal speaker will warn you of an incoming call even though the monitor
may not be switched on.
Off
The internal speaker is switched off.
