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).
Note
If the 100 V slave input is used, and the 0 V and
100 V are incorrectly connected, no pilot tone is
detected on the power amplifier. Refer to
section 4.1 for information.
