External power amplifiers
The voice alarm router has 2 external power amplifier outputs (line level, 1 V) and 1 external
power amplifier input (100 V) to connect two external power amplifiers. The function of the
external power amplifier (e.g. a Plena Power Amplifier) depends on the channel mode for
which the system is configured (see section 1-Channel mode operation, page 77 and section
2-Channel mode operation, page 78).
