CHAPTER 1

Introduction

Description

The PS-20 is a complete and independent power supply, with the added features of 2- and 4-channel operation, monitoring, 2-

channel program input, audio linking and three (3) modes of operation: RTS 2-channel, RTS 4-channel and

Clear-Com

mode.

The PS-20 features two (2) 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, unlike in Clear Com mode,

where the audio and power are on separate lines. Where the PS-15 has power on CH 1 only, power is on both CH 1 and CH 2

on the PS-20.

The PS-20 has a 3-pin XLR (male) connector on the front of the system, where a user can connect to the power supply and

monitor activity on CH 1 or CH 2 (see Figure 1 on page 5). In Clear-Com mode, only channel one (1) is heard. A user station

or beltpack is required to use a headset with this feature.

A single PS-20 Power Supply can power up to 50 user stations (depending on the model and combination - see specifications).

If still more user stations or beltpacks are needed, two PS-20 Power Supplies 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 (2) PS-20 power

supplies through audio linking.

The PGM IN (3-pin XLR female) connector can be used to send Audio to CH 1 and/or CH 2 (for example, a radio station users

can listen to while they work).
