Crown recommends using pre-built or profes- sionally wired, balanced line (two-conductor plus shield), 22-24 gauge cables with 6 AWG terminal forks, less than 0.31 inch (7.8 mm) wide. Unbalanced line may also be used but may result in noise over long cable runs.

Refer to Figure 3.3 for correct 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 3.4). 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.
