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.
