5.1.4 External power amplifier
The voice alarm controller has 1 external power amplifier output (line level, 1 V) and 1
external power amplifier input (100 V) to connect an external power amplifier (see
Figure 5.4). The function of the external power amplifier (e.g. a Plena Power Amplifier 360/
240W) depends on the channel mode for which the voice alarm controller is configured (see
section 6.1.4 and section 6.1.5 ).
