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.
UP-4XP INPUT CONNECTOR
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
