2.5 Output Wiring and Connectors

To drive distributed speaker systems designed to operate at 70V or 100V, connect to
the corresponding output terminals.
JBL recommends using prebuilt or professionally wired, high-quality, two-conductor,
heavy gauge speaker wire. Speakers wires should be twisted cable, if possible. To
prevent the possibility of short-circuits, the wires should be stripped back no greater
than 6 mm (1/4 inch), see Figure 2.5.
Suggested below are guidelines to select the appropriate size of wire based on the
distance from amplifier to speaker. Check with local code as this may vary.
Distance
Up to 25 ft. (7.6m)
26-40 ft. (7.9-12.2m)
