3.4 Choose Input Wire
and Connectors
Figure 3.3 shows connector pin assignments for
balanced wiring, and Figure 3.4 shows connec-
tor pin assignments for unbalanced wiring.
NOTE: Custom wiring should only be per-
formed by qualified personnel.
3.5 Choose Output Wire and Con-
nectors
A protective cover is installed over the barrier-
strip output. Some models have a cover with two
holes. To remove this type of cover:
1. Loosen screws inside top and bottom holes of
cover (see Figure 3.6).
2. Slide cover to left or right, then pull it off away
from the amplifier.
Crown recommends using professionally con-
structed, high-quality, two- or four-conductor,
heavy gauge speaker wire and connectors. You
may use terminal forks up to 10 AWG or bare
wire for your output connectors (see Figure 3.5).
To prevent the possibility of short-circuits, wrap
or otherwise insulate exposed loudspeaker cable
connectors. For best results, Crown recom-
mends Panduit part #PV10-10LF-L or equivalent
terminal fork. Screw spacing is shown in Figure
3.5.
Using the guidelines below, select the appropri-
ate size of wire based on the distance from
amplifier to speaker (low-impedance loads only).
CAUTION: Never use shielded cable for
output wiring.
Replace output cover after output wiring
is complete.
Distance Wire Size
up to 25 ft. (7.6m) 16 AWG
26-40 ft. (7.9-12.2m) 14 AWG
41-60 ft. (12.5-18.3m) 12 AWG
> 60 ft (18.3m) 10 AWG
