2.4 Choose Input Wire and Connectors
recommends using pre-built or professionally
wired, balanced line (two-conductor plus shield), 22-24
gauge cables and connectors. Depending upon which am-
plifier input you choose, you should use either 3-pin male
XLR connectors, or jack connectors for the amplifier inputs.
Unbalanced line may also be used but may result in noise
over long cable runs.
Note: Amplifier input connectors not used for audio signal
input may be used for daisy-chaining of the audio signal
to other components.
Figure 2.2 shows connector pin assignments for balanced
wiring, and Figure 2.3 shows connector pin assignments
for unbalanced wiring.
NOTE: Custom wiring should only be perf-
ormed by qualified personnel.
2.5 Choose Output Wire and Connectors
recommends using pre-built or professionally
wired, high quality, two- or four-conductor, heavy gauge
speaker wire and connectors. You may use two 4-pole Spe-
akon connectors (Figure2.4 and Table 1) or banana plugs,
To prevent the possibility of short-circuits, wrap or otherwise
insulate exposed loudspeaker cable connectors.
CAUTION: Never use shielded cable for output wiring.
