The PS-20 is the latest power supply. The PS-20 features 2- and 4-channel operation, RTS monitoring, 2-channel program input, audio
linking and 3-mode operation: RTS 2-channel, RTS 4-channel and Clear-Com mode. It also has double the power output per channel
of previous RTS power supplies, which will substantially increase the number of user stations and beltpacks that can be connected.
The PS-20 features two channels of communication where both channels are “wet,” meaning there is power on each channel (RTS
2-channel mode). In RTS 4-channel mode, the audio signals and DC exist on the same wire. The PS-20 can also be switched into
Clear-Com mode. The PS-20 has a 3-pin XLR (male) connector on the front of the system, where a RTS user station can connect
and monitor activity on either or both channels. A single PS-20 power supply has 1.8 amps per channel, which means the user can
power up more stations. If additional user stations or beltpacks are needed, two PS-20s can be joined together to double the power
capability. A pair of standard stereo plug connectors are available on the back of the power supply to connect two PS-20s through
audio linking as well. The 3-pin XLR female program input connector can be used to send audio to both CH 1 and/or CH 2.

Power supplies are the heart of partyline intercom systems. They supply operating voltage to beltpacks and many
user stations. Unique, short-circuit reset circuitry design and unparalleled mechanical engineering ensures reliable,
trouble-free operation for years to come. With all of the things you have to worry about, power supplies should not
be one of them.
