XLS Series Power Amplifiers

2 Setup

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. You should use 3-pin male XLR cable ends at the amplifier inputs. Unbalanced line may also be used but may result in noise over long cable runs.

Connector Wiring

Figure 2.3 shows connector pin assignments for balanced wiring, and Figure 2.4 shows connector pin assignments for unbalanced wiring.

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

2.5 Choose Output Wire and Connectors

Crown recommends using pre-built or professionally wired, high- quality, two-conductor, heavy gauge speaker wire and connectors. You may use 2-pole or 4-pole Speakon® connectors (Figure 2.5 ) or banana plugs, spade lugs, or bare wire for your output connec- tors (Figure 2.6). 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.
