2.4Choose Output Wire and Connectors

Amplifier Output Connections: 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. Slip the cable lugs under the output screw terminals and tighten (Figure 2.7). To prevent the possibility of short-circuits, wrap or otherwise insulate exposed loudspeaker cable connectors. Cover the output connections with the supplied non-touch cover.

Using the guidelines below, select the appropriate size of wire based on the distance from amplifier to speaker. The wire sizes apply to the 4-ohm tap.

Distance	Wire Size
up to 25 ft.	16 AWG
26-40 ft.	14 AWG
41-60 ft.	12 AWG
61-100 ft.	10 AWG
101-150 ft.	8 AWG
151-250 ft.	6 AWG

NOTE: Custom wiring should only be performed by qualified personnel. Class 2 wiring is required.

CAUTION: Never use shielded cable for output power wiring.

Use 2-conductor shielded cable and a 3-pin Phoenix-type connector for Preamp Line Output (Figure 2.7), and for MOH 1V or 1W output (Figure 2.8).

Use 1-conductor shielded cable and RCA plugs for the Stereo Line Out connector and the MOH 1V Line Output RCA Connector (Figure 2.9).

Music-On-Hold Connections

You can play music from the XM radio over your phone line while the caller is on hold. Use one of the connectors below to connect the 180MAx to the Music-On-Hold input on your telephone system interface/PBX.

•MOH 1V Line Output Connector: 3-pin Phoenix connector, 600-ohmtransformer-isolated output, provides Music-On-Hold signal of approximately 1 volt. See Figure 2.9.

•MOH 1W Line Output Connector: 3-pin Phoenix connector provides Music-On-Hold signal of approxi- mately 1 watt. See Figure 2.9.

•MOH 1V Line Output RCA Connectors:Two RCA connectors (mono) for 1-voltMusic-On-Hold output (in parallel with 600-ohm connectors, so they are isolated). See Figure 2.10.
