CHAPTER 2: ULTRA XP LOUDSPEAKERS

LOUDSPEAKER INPUT CONNECTOR

Ultra XP loudspeakers receive DC power and balanced audio from a single input connector, available as Phoenix™ 5-pin
male, SwitchCraft ® EN3™ 5-pin male, or ECO-M 7-pin male. The sealed EN3 and ECO-M connectors are ideal for outdoor,
all-weather use. To function properly, Ultra XP loudspeakers require an external MPS-488HP IntelligentDC power supply.
All connectors include two pins for DC power (positive and negative) and three pins for balanced audio (positive, negative, and
shield). Pin outputs are clearly labeled on loudspeaker user panels (pins 3 and 4 for ECO-M connectors are not used by
Ultra XP loudspeakers). Ultra XP loudspeakers ship with an appropriate cable accessory for assembling loudspeaker cables
(see Table 1). For more information, see "Belden 1502 Cable (or Equivalent)" on page 10 and Appendix B, "Assembling Loud-
speaker Cables."

CAUTION: When wiring Ultra XP 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 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.
