Automatic gain control
Use the AGC menu item to enable or disable the AGC of the audio inputs. If necessary, enable
the AGC for the audio inputs that inject external interpretations in the system. The AGC
makes sure that the nominal level of the received interpretations is 9 dBV (XLR), -6 dBV
(cinch). When the nominal input of an external interpretation is high, the audio of the external
interpretations will be too loud compared to the audio of the 'internal' interpretations from
the interpreter desks.
NOTICE!
When channel 00 is assigned to an audio input, the system automatically disables AGC for the
audio input. You cannot manually enable AGC for an audio input to which channel 00 is
attached.
NOTICE!
If two systems are connected by audio connections (Cobranet, AEX, or DEX), set the AGC to
off.
