2 Setup
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. At the amplifier inputs, use either:
• 3-pin male XLR cable ends,
• TRS or TS 1/4" phone plugs, or
• Phoenix-style connectors (2-channel models only).
Unbalanced lines may be used, but may result in noise over long
cable runs.
Figure 2.3 shows XLR wiring, Figure 2.4 shows 1/4" phone plug
wiring, and Figure 2.5 shows Phoenix-style connector wiring.
NOTE: Custom wiring should only be performed by qual-
ified 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 can use banana plugs, spade lugs, or bare wire
for your output connectors (Figure 2.6). Also, in the 2-channel
®
models, you can use a 4-pole Speakon connector (Figure 2.7
and Table 1). 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.
