The PS-20 is a two-wire intercom power supply. The PS-20 features two- and four-channel operation, RTS® monitoring, two-channel program input, audio linking, and three-mode operation: RTS 2-channel, RTS 4-channel and Clear-Com® mode. It also has double the power output of the PS-31 per channel, which will increase the number of user stations and beltpacks which can be connected substantially.

The PS-20 features two channels of communication where both channels are "wet", meaning there is power on each channel (two-channel mode). In four-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 ampere per channel which means the user can power up more stations. If additional user stations or beltpacks are needed, two PS-20's 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-20's through audio linking as well. The PGM IN (3-pin XLR female Program Input) connector can be used to send audio to both CH 1 and/or CH 2.

Features:

  • Selectable Mode Operation
    The PS-20 is selectable between RTS 2-channel, RTS 4-channel and Clear-Com mode.
  • There is an audio link connection (1/4" (6.3mm) Stereo plug) on the back of the unit.
  • The 3-pin XLR Monitoring output connector on the front of the PS-20 allows the user to connect a RTS user station to monitor a channel or both channels.
  • There is a green status indicator for each channel on the front of the unit. Each of these indicators will remain lit during normal operation, but will turn RED during a channel current overload condition. Output current is automatically reduced during an overload, and normal operation is restored when the overload is removed.
  • There is a Program Input connector on the rear panel. This can be used to connect a device that both channel 1 and channel 2 can listen to at the same time. A Channel Select switch on the front panel assigns the program to either or both channels. A Level control adjusts the program level to the intercom channel.
  • Intercom Channels Connections
    Intercom channels (user stations) are connected to the rear panel of the PS-20 with 3-pin XLR connectors.
  • Selectable Termination Impedance
    The IMPEDANCE SELECT switch on the rear panel allows each channel to be set for 200O or 400O operation. Select 200O for each channel operated independently. Select 400O for each channel connected to another channel.
