Figure 4. US2000A Monaural Master Speaker Station Configuration with 1
Power Supply. This is a good configuration for smaller intercom systems when you
want to operate the US2000A as a master speaker station, with one speaker to
monitor both intercom channels. In this configuration, the SPS2000A
Combine/Isolate switch is set to the Isolate position. With this setting the 2 intercom
channels are completely separated. The amplified speaker in the SPS2000A is
used as the speaker output for the US2000A, and the US2000A dip switches are
set to monaural operation so that both intercom channels are heard in the speaker.
The PS-L local power supply is optional. When a PS-L is connected, the US2000A
automatically disconnects from system power (supplied by the SPS2000A). When
the US2000A is not drawing power from the intercom system, more system power
is available for additional belt packs, etc.
