3.4 Choose Input Wire

and Connectors

Crown recommends using pre-built or profes- sionally wired, balanced line (two-conductor plus shield), 22-24 gauge cables and connec- tors.The factory-installed PIP2-FXQ input mod- ule accepts 3-pin male XLR connectors or TRS phone connectors. Other PIP modules accept XLR, phone or Phoenix connectors, or bare wires.

Regarding the PIP2-FXQ, Figure 3.3 shows con- nector pin assignments for balanced wiring, and Figure 3.4 shows connector pin assignments for unbalanced wiring.

NOTE: Custom wiring should only be per- formed by qualified personnel.

3.5 Choose Output Wire and Con- nectors

Crown recommends using pre-built or profes- sionally wired, high-quality, two-conductor, heavy gauge speaker wire. Use bare wire, a dual banana plug or spade lugs on the amplifier end of each speaker cable (Figure 3.5). To prevent the possibility of short-circuits, wrap or other- wise insulate exposed loudspeaker cable con- nectors.

Using the guidelines below, select the appropri- ate size of wire based on the distance from amplifier to speaker.

Distance

Wire Size

up to 25 ft.

16 gauge

26-40 ft.

14 gauge

41-60 ft.

12 gauge

61-100 ft.

10 gauge

101-150 ft.

8 gauge

151-250 ft.

6 gauge

CAUTION: Never use shielded cable for output wiring.
