2.5 Output Wiring
To drive distributed speaker systems designed to operate at 70V or 100V, connect the
amplifier to a CST-2120 transformer module with the jumper cable that shipped with the
CST-2120 transformer module, see Figure 2.5.1.
JBL recommends using pre-built 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 2.5.2.
Suggested below are guidelines to select the appropriate size of wire based on the dis-
tance from amplifier to speaker. Check with local code as this may vary.

NOTE:
If driving a 70V or 100V distributed speaker system, use the optional CST-2120
transformer module (see Appendix A).
