12.6.3 Equalized PA
In the Equalized PA mode, audio output 2 of the central
control unit transmits a signal that you can connect to
an external public address system (refer to figure 12.2).
The central control unit sets:
• The volume level of the signal
• The levels of the bass of the signal
• The level of the treble signal
In the Equalized PA mode, the signal on audio input 2 of
the central control unit is added to the floor signal.
12.6.4 Insertion
In the Insertion mode, audio output 2 and audio input 2
of the central control unit are used to add signals from
external audio devices (refer to figure 12.3). For
example, you can connect an external audio mixer
between audio output 2 and audio input 2 of the central
control unit.
In the Insertion mode, you must install a device between
audio output 2 and audio input 2 of the central control
unit. When you do not install a device, the audio signals
from contribution devices (floor) leave the system, but
do not enter the system again.
