Crown recommends using pre-built or professionally wired bal- anced line (two-conductor plus shield), 22-24 gauge cables and connectors. Unbalanced line may also be used but may result in noise over long cable runs.

The 180MAx has two types of input connectors: Phoenix-type and RCA.

Mic/Line Connectors and Amp Input Connectors: 3-pinPhoenix-type, balanced, one per input channel (Figure 2.3).

Dual RCA Input Connector: For stereo music signals, unbalanced, summed together, two connectors per input for inputs 1, 2 and 3 (Figure 2.4).

Transformer-isolated 600-ohm input: 3-pin Phoenix- type. Summed into Input 1 for paging from a telephone system. See Figure 2.5.

The 180MAx also has an XM antenna connector for use with the supplied XM radio antenna.
