Figure 8. US2000A Binaural 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 a separate speaker for each intercom channel. In this configuration,
the SPS2000A Combine/Isolate switches are set to the Combine position. With this
setting all intercom stations connected to the one SPS2000A are combined on
intercom channel 1 and all intercom stations connected to the other SPS2000A are
combined on channel 2. The amplified speaker in each SPS2000A monitors a
single intercom channel, and the US2000A dip switches are set to binaural
operation (see page
). 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.
