Assembling Loudspeaker Cables
Assembling Pheonix-to-Pheonix Loudspeaker Cables
Caution
When wiring loudspeaker cables, it is extremely important that each pin be wired correctly. Make sure the 48 V DC from the external power supply is wired directly (and only) to the 48 V DC pins on the loudspeaker connector, and the polarity is observed (negative to negative, positive to positive) to avoid damage to the loudspeaker and/or power supply. In addition, make sure that audio pins are wired correctly; polarity reversals for audio signals affect system performance.
When connecting loudspeakers and power supplies equipped with Phoenix connectors, a cable terminated with 5-pin female Phoenix connectors at both ends is needed. The following procedure documents how to assemble these cables.
Remove 1 inch [2.5 cm] of the outer jacket and then strip the black, red, blue, and white wires by 0.275 inches [0.7 cm].
Add non-conductive insulation tubing to the shield conductor, cut to length so that 0.275 inches [0.7 cm] of the conductor is left exposed. This prevents unintentional shorting to other conductors.
Insert the five exposed conductors into the five cable holes of a 5-pin female Phoenix cable mount connector. Use the following wiring scheme.

Proper Assembly of 5-Pin Phoenix Female Connector
Secure the conductors by tightening the screws in the Phoenix cable mount connector. Screws should be torqued to 0.5–0.6 N·m [4.4 - 5.3 in-lb]. Tug the conductors to ensure they are sufficiently retained.
Caution
Screws should not be tightened while the connector is mated to a male Phoenix connector. Doing so will damage the contacts. During assembly, the Phoenix connector should only be held in place externally.
Repeat the previous steps and attach the other end of the cable to another 5-pin Phoenix female cable mount connector.
6. Verify the wiring polarity is correct for both cable ends.
