Figure 4. Typical Rack Mount Configuration for a 10-Channel Master Speaker Station with Minimum Power Supply
Configuration. The SPS-2000A provides power for channels 1 and 2, and also provides the listening speaker for all 10 chan-
nels. A microphone must be connected to the US2000A for talk on the 10 channels. Each PS4000 provides power for 4 inter-
com channels and also interfaces an ES4000A to the intercom channels. The XP-USPG interfaces 2 external program inputs to
the US2000A, and also interfaces the US2000A to an external PA system. Each XP-4PGM interfaces 4 external program
sources to an ES4000A. Connections and further details for this configuration are shown in Figure 6
. Note: An additional rack
space is shown between the two PS4000 power supplies. This may be required to prevent power supply overheating when the
ambient air temperature is high.
