Crown recommends using pre-built or profes- sionally wired, balanced line (two-conductor plus shield), 22-24 gauge cables and connec- tors. You should use 3-pin male XLR cable ends at the amplifi er inputs. Unbalanced line may also be used but may result in noise over long cable runs.

Note: Male XLR signal links are also provided on the amplifi er to allow daisy-chaining of the audio signal.

Refer to Figure 3.4 for correct XLR connector pin assignments.

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

Crown recommends using pre-built or pro- fessionally wired, high-quality, two- or four- conductor, heavy gauge speaker wire and connectors. You may use banana plugs, spade lugs or bare wire for your output connectors (see Figure 3.5). To prevent the possibility

of short-circuits, wrap or otherwise insulate exposed loudspeaker cable connectors.

Using the guidelines below, select the appro- priate size of wire based on the distance from amplifi er to speaker.

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

CAUTION: Never use shielded cable for output wiring.
