Conference System
Insertion no AGC
In the Insertion no AGC mode, audio output 2 and audio input 2 of the central control unit are
both used to add signals from external audio devices. For example, connection of an external
audio mixer between audio output 2 and audio input 2 of the central control unit. The
difference between the Insertion mode is that AGC and the noise gate are disabled. This also
results in a 12dB lower audio level.

Local floor mode, audio output 2 of the central control unit only transmits the floor signal of
the units connected to the DCN-CCU2. In this way audio outputs 2 of the slave CCUs can be
connected to multiple external public address system.
