OVERVIEW Sw4spkr 4 zone impedance Matching speaker selector:
OEM switchers provide nominal 8 Ohm load for amplifier protection against low impedance loads.
Barrier Termination Strip Construction provides positive wire terminations much superior to the “Quick Connect” type. This design is preferred by experienced installation experts over inferior quick connect types.
Individual on/off switches for each pair of speakers.
Heavy Duty metal chassis and cases with high grade circuit boards.
The SW-4SPKR is designed to allow up to 4 pairs of 8 Ohm speakers to be connected to a stereo amplifier or receiver without damaging the amplifier. These devices also function as “Switching Stations” to control all the speakers in a multi-room system from a central location.
The buttons are used to turn the individual pairs of speakers ON & OFF. If you want to maintain individual volume control over each pair of speakers, heavy duty “Autoformer” type volume controls should be used (1 for each pair of speakers). These volume controls must be located, in-line, between the SW-4SPKR and each speaker pair.
Wiring from the amplifier to the SW-4SPKR should be a minimum of 16 gauge (14 gauge recommended) . If wire is to be run through walls, it should be “CL” rated. For runs over 100 feet 14 gauge wire may be used
