Central Master Station vs Remote Station
The US2000A can be used in a variety of configurations as a speaker station or as a
headset station. Additionally, it can be used as a central master station or as a remote
station. When used as a central master station, the US2000A is placed in the same lo-
cation as the system power supplies, and if an SPS2000A power supply is used, the
US2000A can take advantage of the SPS2000A built-in speaker for speaker output.
When used as a remote station, the US2000A is not at the same location as the power
supplies, and if it is being used as a speaker station, a separate speaker must be sup-
plied. Figures 4 through 12 , starting on page 15 , illustrate several configurations for
the US2000A when used as a central or remote headset or speaker station.
All Locally Powered Stations
Any US2000A can be locally powered by connecting a PS-L Local Power Supply.
This is shown as an option in Figures 4 through 12 . A special case is an intercom
system where all stations are powered from local power supplies, with no central
power supply. This is illustrated in Figure 13 , page 24 .
External Program Input and PA Output
Connections for external program input and PA output are shown in Figure 14 , page 25 .
