2.4 Choose Input Wire
and Connectors
Figure 2.3 shows connector pin assignments for
balanced wiring, and Figure 2.4 shows connec-
tor pin assignments for unbalanced wiring.
NOTE: Custom wiring should only be per-
formed by qualified personnel.
2.5 Choose Output Wire and
Connectors
Crown recommends using professionally con-
structed, high-
quality, two- or four-conductor, heavy gauge
speaker wire and connectors. You may use ter-
minal forks or bare wire for your output connec-
tors (see Figure 2.5). To prevent the possibility
of short-circuits, wrap or otherwise insulate
exposed loudspeaker cable and connectors.
Using the guidelines below, select the appropri-
ate size of wire based on the distance from
amplifier to speaker.
CAUTION: Never use shielded cable for
output wiring.
Distance Wire Size
up to 25 ft. 16 AWG
26-40 ft. 14 AWG
41-60 ft. 12 AWG
Over 60 ft. 10 AWG
