Central Master Station vs. Remote Station

The US-2002 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 US-2002 is placed in the same 
location as the system power supplies, and if an SPS2001 power supply is used, the US-2002 can take advantage of the 
SPS2001 built-in speaker for speaker output. When used as a remote station, a separate speaker must be supplied. Figures 4 
through 12, starting on page 15, illustrate several configurations for the US-2002 when used as a central or remote headset or 
speaker station.

All Locally Powered Stations

Any US-2002 can be locally powered by connecting a PS-KP 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 on page 24.

External Program Input and PA Output

Connections for external program input and PA output are show in Figure 14 on page 25.
