• 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.
