100 V slave input

The power amplifiers have a 100 V slave input (18) that
can be connected to an existing 100 V loudspeaker line.
In this way it is easy to connect an additional power
amplifier on a remote location for more output power.
The 100 V input is not affected by the control terminals
for input 1 priority (20) or input 2 enable (19).
