APPENDIX B: PHOENIX AND EN3 CABLE ASSEMBLY
CAUTION: When wiring cable connections for MPS-488HP Channel Outputs, it is extremely important that each
pin in the connector be wired correctly. Make sure the 48 V DC from the MPS-488HP 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 rever-
sals for audio signals affect system performance.
ASSEMBLING EN3-TO-EN3 LOUDSPEAKER CABLES
When connecting loudspeakers equipped with EN3 connectors to the MPS-488HPe power supply, you need an EN3 5-pin
female to EN3 5-pin male cable. The following procedure documents how to assemble this cable. If you are starting with an
EN3-to-pigtail cable, you can skip step 5 in this procedure.
NOTE: Cable mount connectors cannot connect to other cable mount connectors. Cable mount connectors
can only connect to panel mount connectors (like those on the MPS-488HPe) or inline connectors. To extend
cables with EN3 connectors on both ends you can use an EN3 5-pin female-to-male cable coupler.
To assemble an EN3-to-EN3 loudspeaker cable:
1. Disassemble the EN3 5-pin male connector and feed one end of the cable through the boot, cable clamp housing, and
coupling ring.
