Description
The US2000A Intercom User Station is designed for stationary use by personnel who
may require selective access to two or more intercom channels. It can be rack
mounted or used as a desktop station. For rack mounting, optional hardware is re-
quired. For desktop use, four rubber feet are supplied.
The US2000A can be used as a simple, multi-channel user station. Typically, in this
application, no program sources or public address output are connected, and some
advanced features can be disabled: the station simply provides talk, listen and call
capability for a single user. Alternatively, the US2000A can function as a master sta-
tion. In this configuration, most or all advanced features are activated. Also, program
inputs and a public address output may be connected. This configuration is ideal for
command and control personnel such as directors, supervisors, etc.
The basic US2000A can communicate with two intercom channels. This number can
be increased by connecting optional ES4000A Expansion Stations. Each ES4000A
adds four additional channels, and up to four of these expansion stations can be con-
nected for a total of eighteen channels.
