Crown recommends using pre-built or profes-
sionally wired, balanced line (two-conductor 
plus shield), 22-24 gauge cables and connec-
tors. Depending upon which amplifier input you 
choose, you should use either 3-pin male XLR 
connectors, TRS phone connectors, or terminal 
forks at the amplifier inputs. 

Unbalanced lines may also be used but may 
result in noise over long cable runs. 

The amplifier input connectors not used for 
audio signal input may be used to daisy-chain 
the audio signal to other components.

Figure 3.3 shows connector pin assignments for 
balanced wiring, and Figure 3.4 shows connec-
tor pin assignments for unbalanced wiring

NOTE: Custom wiring should only be
performed by qualified personnel.
