Figure 9. US2000A Headset Station Configuration
with 2 Power Supplies. In this configuration, the PS2000L Combine/Isolate
switches are set to the Combine position. With this setting all intercom stations
connected to the one PS2000L are combined on intercom channel 1 and all
intercom stations connected to the other PS2000L are combined on channel 2.
Typically, a headset is connected to the front panel of the US2000A, and the
US2000A dip switches are set to monaural operation (default setting) so that both
intercom channels are heard in the monaural headphones (binaural headphone
operation is not supported). 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.
