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.
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 maximize the low fre-
quency output when used with the C8.2,C8.2LP
or C8.2HC,
the polar
ity of the C10.1 subw
oof
er
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
thr
ough 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
