2.4 Choose Input Wire
and Connectors

Crown recommends using pre-built or professionally wired bal-
anced line (two-conductor plus shield), 22-24 gauge cables and
connectors. You should use 3-pin male XLR cable ends at the
amplifier inputs. Unbalanced line may also be used but may
result in noise over long cable runs.

Figure 2.3 shows connector pin assignments for balanced wiring,
and Figure 2.4 shows connector pin assignments for unbalanced
wiring.

NOTE: Custom wiring should only be performed by
qualified personnel.

2.5 Choose Output Wire and Connectors

Crown recommends using pre-built or professionally wired, high-
quality, two- or four-conductor, heavy gauge speaker wire and
connectors. You may use a 4-pole Speakon

connector (Figure

2.5 and Table 1) or banana plugs, spade lugs, or bare wire for
your output connectors (Figure 2.6). To prevent the possibility of
short-circuits, wrap or otherwise insulate exposed loudspeaker
cable connectors.

Note: Binding post outputs on European models come
with safety plugs installed to prevent European power-
cord plugs from being inserted. The top & bottom entry
positions for these connectors should therefore be used
with European models.

Using the guidelines below, select the appropriate size of wire
based on the distance from amplifier to speaker.

Distance Wire Size
up to 25 ft. 16 AWG

26-40 ft. 14 AWG

41-60 ft. 12 AWG

61-100 ft. 10 AWG

101-150 ft. 8 AWG

151-250 ft. 6 AWG

CAUTION: Never use shielded cable for output wiring.
