The booster amplifiers have a 100 V slave input that can be connected to an existing 100 V loudspeaker line. In this
way it is easy to connect an additional booster amplifier on a remote location for more output power.
The 100 V input of the LBB1938 (13) is not affected by the control terminals for input 1 priority (15) or input 2
enable (14).
