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. Unbalanced line may also be used but may result in	PRIORITY
noise over long cable runs.
The 135MA and 160MA have two types of input connectors:
Phoenix-type and RCA.

•Mic/Line Connector (CH1): 5-pinPhoenix-type, balanced, pins 3, 4 and 5 (Figure 2.3).

•Dual RCA Input Connector (other channels): For stereo music signals, unbalanced, summed together, two connectors per input (Figure 2.4).
