Line Settings
• A separate Automatic Gain Control (AGC) can be switched on for both
channels.
Please select the desired line with your mouse and press the button Edit,
which opens the configuration window. To switch off the AGC select Off.
To switch it on select On.
FIG. 16 CONFIGURATION AGC AND ECHO CANCELLER
Via the button Set AGC on/off for all lines you can switch on respectively
switch off the AGC for all lines.
ATTENTION An Automatic Gain Control is reasonable if you do not have the possibility
for Pre Talk during which the level can be adjusted.
But: An AGC is no wizard. Extremely low callers cannot be boosted bound-
lessly. Extremely loud callers cannot be toned down boundlessly.
