• The PS-20 is selectable between RTS 2-channel,

RTS 4-channel and Clear-Com mode.

• There is an audio link connection (¼-inch (6.3 mm)

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 (user stations) are connected to the

rear panel of the PS-20 with 3-pin XLR connectors.

• The impedance select switch on the rear panel allows

each channel to be set for 200Ω or 400Ω operation.

Select 200Ω for each channel operated independently.

Select 400Ω for each channel connected to another

channel.
