APPENDIX B: ASSEMBLING LOUDSPEAKER CABLES
CAUTION: When wiring loudspeaker cables, it is extremely important that each pin be wired correctly. Make
sure that 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 that the polarity is observed (negative to negative, positive to positive) to avoid damage
to the loudspeaker. In addition, make sure that audio pins are wired correctly; polarity reversals for audio signals
affect system performance.
ASSEMBLING PHOENIX-TO-PHOENIX LOUDSPEAKER CABLES
When connecting loudspeakers and power supplies equipped with Phoenix connectors, you need a Phoenix 5-pin female to
Phoenix 5-pin female cable. The following procedure documents how to assemble this cable.
To assemble a Phoenix-to-Phoenix cable:
1. If the cable has not yet been stripped, strip one end of the cable. Strip the outer shielding by 1 inch and then strip the
black, red, blue, and white wires by 0.275 inch.
2. Insert the five exposed conductors into the five cable holes in a Phoenix 5-pin female cable mount connector. Use the
following wiring scheme.
3. Secure the conductors by tightening the five screws in the Phoenix cable mount connector. Screws should be torqued
to 5–6 Nm (4.4–5.3 In-Lbs).
