2.3.2Choose Input Wire and Connectors

Crown recommends using pre-built or professionally wired, balanced line (two-conductor plus shield), 22-24 gauge cables and connectors. Use 3-pin male XLR connectors.

Unbalanced line may also be used but may result in noise over long cable runs.

Figure 2.5 shows connector pin assignments for balanced analog wiring or AES/EBU digital wiring. The use of standard analog cable with AES/EBU will result in diminished performance. For best results, 110 ohm shielded twisted-pair cable for AES/EBU signals is highly recommended. Figure 2.6 shows connector pin assignments for unbalanced analog wiring.

NOTE: Custom wiring should only be performed by qualifi ed personnel.

2.3.3 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. Use Class 2 output wiring. You may use a 4-pole Speakon® connector (Figure 2.7) or banana plugs, spade lugs, or bare wire for your output connectors (Figure 2.8). To prevent the possibility of short circuits, wrap or otherwise insulate exposed loudspeaker cable connectors.

CAUTION – SHOCK HAZARD: Potentially lethal voltages exist at the output connectors when the amplifier is turned on and is passing a signal.

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