The 4PS Four Pair manual Stereo Speaker Selector is a self contained passive
selector box. It allows the user to control up to 4 separate pairs of stereo
speakers from one amplifier without an expensive electronic distribution system. It
requires no external power to operate.
The 4PS is used for multiroom stereo sound systems. With the 4PS the user can
selectively turn ON or OFF any one of four zones. The unit has a built-in
impedance compensating network to prevent overload to the amplifier. Unlike others
on the market, no switch is required to activate the protection circuit. The
protection circuit is always On.
Each spring loaded connector can handle up to a 14 gauge wire. There is a Red/
Black connector pair for each speaker, and one set ( Right and Left) for the
amplifier source input. The speakers are arranged in 4 zones. Make sure the
polarity is observed. You can hook-up one, two, three or four pairs of speakers.
Once the 4PS is properly hooked-up operation is straightforward. Select a Zone or
any combination of Zones and press the corresponding button for that Zone. The
button will be indented to indicate ON. Push again and it will release and indicate
OFF. For example press buttons 1 and 3 to listen to music in Zones 1 and 3. The
buttons that are out indicate OFF and no sound will be heard from that Zone.
