3.4 Choose Input Wire

and Connectors

Crown recommends using pre-built or profes- sionally wired, balanced line (two-conductor plus shield), 22-24 gauge cables and connec- tors. Use either 3-pin male XLR connectors or TRS phone connectors.

Figure 3.3 shows connector pin assignments for balanced wiring, and Figure 3.4 shows connec- tor pin assignments for unbalanced wiring.

NOTE: Custom wiring should only be per- formed by qualified personnel.

3.5Choose Output Wire and Con- nectors

Crown recommends using pre-built or profes- sionally wired, high-quality, two-conductor, heavy gauge speaker wire. Use bare wire, a dual banana plug or spade lugs on the amplifier end of each speaker cable (Figure 3.5). To prevent the possibility of short-circuits, wrap or other- wise insulate exposed loudspeaker cable con- nectors.

Using the guidelines below, select the appropri- ate size of wire based on the distance from amplifier 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
