Connection
The SW-8SPKR uses removable connectors (Fig. A). This allows the
zones to be quickly reconfigured by swapping the plug positions. It
can also make it easier to connect each pair of wires.
Connect the speakers to the speaker selector as shown in the
diagrams. Then connect the amplifier output to the input of the
speaker selector. Use care to maintain proper polarity on all connections.
A loss of fidelity may occur if speakers are wired out of phase.
Strip approximately ¼
"
(6mm) of insulation from each conductor and insert it into the hole in the back of the connector.
Tighten the screw to clamp the wire. (Wiggle the wire and retighten the screw to ensure a strong long-lasting connection.)
