CHAPTER 2: UP-4XP LOUDSPEAKER

The UP-4XP is powered by an external 48 V DC power sup-

ply, eliminating the need for wiring conduits while still pre-

serving the advantages of self-powered loudspeaker

systems. The unit's onboard amplifier and signal-processing

circuits were designed to store DC power and tolerate volt-

age drops, thereby accommodating light-gauge cables and

lengthy cable runs.

The UP-4XP loudspeaker is available with either a Phoenix

5-pin male or SwitchCraft EN3 5-pin male connector for

receiving DC power and balanced audio. The EN3 connec-

tor is ideal for outdoor, all-weather use. The input connec-

tor’s five pins include two for DC power (negative and

positive) and three for balanced audio (shield, negative, and

positive). These pins are clearly labeled on the UP-4XP rear

panel. To function properly, the UP-4XP requires 48 V of DC

power.

Depending on the loudspeaker’s connector, the UP-4XP

ships with either a single Phoenix cable mount connector or

a 10-foot (3 meter) EN3-to-pigtail cable for constructing

loudspeaker cables. For information on UP-4XP cable

requirements, see “UP-4XP Current Draw and Cable

Requirements” on page 13. For information on cables and

cable accessories available from Meyer Sound, see
