INSTALLATION NOTE: CONNECTOR
WIRING GUIDELINES
The input connector’s 4 terminals are num-
bered 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 con-
nected 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 speakers 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, sub-
sequent speakers will also be disconnected.
See Figure 10.
INSTALLATION NOTE: SUBWOOFER
POLARITY
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 maxi-
mize the low frequency 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 speak-
er’s terminal block. Then tighten the strain
relief fitting as follows:
