2.3 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 Phoenix-type 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 wir-
ing, and Figure 2.4 shows connector pin assignments for unbal-
anced wiring. The RCA input connectors can also be used for
unbalanced inputs.

2.4 Choose Output Wire and Connectors

For the amplifier output connectors, Crown recommends using
pre-built or professionally wired, high-quality, two-conductor,
heavy gauge speaker wire and connectors. You may use crimp-
on spade lugs for your output connectors (Figure 2.5). To prevent
the possibility of short-circuits, wrap or otherwise insulate
exposed loudspeaker cable connectors. Cover the output con-
nections with the supplied non-touch cover.
Using the guidelines below, select the appropriate size of wire
based on the distance from amplifier to speaker. The wire sizes
apply to the 4-ohm tap.
Distance
up to 25 ft.
26-40 ft.
41-60 ft.
61-100 ft.
101-150 ft.
151-250 ft.
CAUTION: Never use shielded cable for output power
wiring.
NOTE: Custom wiring should only be performed by
qualified personnel. Class 2 wiring is required.
Use 2-conductor shielded cable and 3-pin Phoenix-type connec-
tors for Line Output wiring (Figure 2.6)
