Installation and Wiring

WIRING GUIDELINES

The input connector’s 4 terminals are numbered and marked on the connector. Pins 1 and 2 are positive (+);pins 3 and 4 are negative (–). (Pin 1 is connected to Pin 2 and Pin 3 is connected to Pin 4 inside the speaker.) Pins 1 and 4 are used as daisy-chain connections to other loudspeakers. Two possible layouts for wiring a group of speak- ers are described below.

1.Wiring in parallel. Connect the wire pair of the subsequent speaker to pins 2 and 3.When one input connector is removed, subsequent speakers will remain connected. See Figure 9.

2.Daisy-chaining. Connect the wire pair of the subsequent speaker to pins 1 and 4.When one input connector is removed, subsequent speakers will also be disconnected. See Figure 10.

When adding a subwoofer, be sure to observe the correct polarity.The C10.1 subwoofer has been designed for optimum performance when used with the C4.2. In order to maximize the low fre- quency output when used with the C8.2, C8.2LP or C8.2HC, the polarity of the C10.1 subwoofer should be reversed. See Figures 11 and 12.

When all wiring has been completed to the connector, plug the connector into the socket in the speaker’s terminal cup. See Figure 13.Tighten all screws to eliminate vibration.

Step 4: Secure the Cable to the Speaker (Figure 14)

Fully loosen the horizontal screw shown in Figure 13,then the strain relief screws. Run the wires through the opening in the fitting and plug the input connector into the speaker’s terminal block. Then tighten the strain relief fitting as follows:

1. If plenum cable is used,slide the wiring
