2.4Choose 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.

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, 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
