The module is designed to connect UZ-ELA modules. UZ-ELA = Control sub-center for loudspeaker
system (German derivation "UnterZentrale für Elektronische LautsprecherAnlage").
All interfaces (RS485) are galvanic isolated, protected against overvoltage and overcurrent.
The UZ-ELA-module allows remote PA.
A 2W-amplifier is integrated.
External PA-amplifiers can be connected. The feedback of the loudspeaker cable to the 100V input
enables the monitoring of the loudspeaker line.
The configuration of UZ-ELA modules is done with Separate amplifier in the menu Call stations and
devices.
