Crown recommends using professionally
con structed, high-quality, two- or four-conductor,
heavy gauge speaker wire and connectors. You
may use terminal forks up to 10 AWG or bare wire
for your output connectors (see Figure 3.5). To
prevent the possibility of short-circuits, wrap or
otherwise insulate exposed loudspeaker cable
connectors. For best results, Crown recom mends
Panduit part #PV10-10LF-L or equivalent
terminal fork. Screw spacing is shown in Figure
3.5.
