Figure 7. US2000A Monaural Master Speaker Station Configuration with 2
Power Supplies. This is a good configuration for large 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 and PS2000L
Combine/Isolate switches are set to the Combine position. With this setting all
intercom stations connected to the SPS2000A are combined on intercom channel 1
and all intercom stations connected to the PS2000L are combined on channel 2.
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 (default
setting) 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. Since the US2000A is not drawing power from the
intercom system, more system power is available for additional belt packs, etc.
Note: For further infor-
mation about the cable
numbers, see page

Note: A BOP-1000 may
be used to rack mount 2
TW-7W splitters.
