2.3 Choose 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 Phoenix-type cable ends at the amplifier inputs. Unbalanced line may also be used but may result in noise over long cable runs.

anced wiring. The RCA input connectors can also be used for

 

 

unbalanced inputs.

2.4 Choose Output Wire and Connectors

For the amplifier output connectors, Crown recommends using pre-built or professionally wired, high-quality, two-conductor, heavy gauge speaker wire and connectors. You may use crimp- on spade lugs for your output connectors (Figure 2.5). To prevent the possibility of short-circuits, wrap or otherwise insulate exposed loudspeaker cable connectors.
