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 and connec-
tors. Use either 3-pin male XLR connectors or
TRS phone 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
Crown recommends using pre-built or profes-
sionally wired, high-quality, two-conductor,
heavy gauge speaker wire. Use bare wire, a dual
banana plug or spade lugs on the amplifier end
of each speaker cable (Figure 3.5). To prevent
the possibility of short-circuits, wrap or other-
wise insulate exposed loudspeaker cable con-
nectors.
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 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
