3 Setup
3.4 Choose Input Wire
and
Connectors
Crown recommends using pre-built or profes-
sionally wired, balanced line (two-conductor
plus shield), 22-24 gauge cables with 6 AWG
terminal forks, less than 0.31 inch (7.8 mm)
wide. Unbalanced line may also be used but
may result in noise over long cable runs.
Refer to Figure 3.3 for correct connector pin
assignments.
NOTE: Custom wiring should only be
performed by qualifi ed personnel.
Figure 3.4 Output Connector Wiring
3.5 Choose Output Wire
and
Connectors
Crown recommends using pre-built or pro-
fessionally wired, high-quality, two- or four-
conductor, heavy gauge speaker wire and
connectors. You may use banana plugs, spade
lugs or bare wire for your output connectors
(see Figure 3.4). To prevent the possibility
of short-circuits, wrap or otherwise insulate
exposed loudspeaker cable connectors.
Using the guidelines below, select the appro-
priate size of wire based on the distance from
amplifi er to speaker.
Distance Wire Size
up to 25 ft. 16 gauge
26-40 ft. 14 gauge
41-60 ft. 12 gauge
61-100 ft. 10 gauge
101-150 ft. 8 gauge
151-250 ft. 6 gauge
CAUTION: Never use shielded cable for
output wiring.
