WIRING UP-4XP LOUDSPEAKER CABLES
WITH BELDEN 1502 CABLE (OR EQUIVALENT)
WITH BELDEN 1502 CABLE (OR EQUIVALENT)
The most convenient method of wiring UP-4XP loudspeaker
cables is with a multiconductor cable such as Belden 1502,
which has dedicated conductors for DC power and bal-
anced audio in a single jacket. When wiring UP-4XP loud-
speaker cables with Belden 1502, use the conventions in
Table 3. The red and black wires are 18 AWG, thicker than
the other three wires, and should be used for DC power
(cable lengths up to 150 feet are possible with just 1 dB of
peak SPL loss). The blue, white, and shield drain wires are
shielded together and should be used for audio.

CAUTION:
When wiring UP-4XP 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 UP-4XP loudspeaker con-
nector, 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.

Wiring EN3-to-Pigtail Cables
UP-4XP loudspeakers equipped with EN3 connectors are
shipped with one EN3 5-pin female-to-pigtail cable. The
EN3 end of the cable connects directly to the UP-4XP input
connector. The pigtail end of the cable, which connects to
the loudspeaker’s external power supply, can be terminated
with either an EN3 5-pin male connector (included with the
MPS-488HPe) or Phoenix 5-pin female connector (included
shipped with one EN3 5-pin female-to-pigtail cable. The
EN3 end of the cable connects directly to the UP-4XP input
connector. The pigtail end of the cable, which connects to
the loudspeaker’s external power supply, can be terminated
with either an EN3 5-pin male connector (included with the
MPS-488HPe) or Phoenix 5-pin female connector (included
with the MPS-488HPp). The pigtail can also be spliced to a
longer loudspeaker cable or to a junction box. The included
EN3-to-pigtail cable uses Belden 1502 cable (or equivalent),
which can be wired for both DC power and balanced audio.
The EN3-to-pigtail cable is available in plenum or regular
(non-plenum) versions.

LONG CABLE RUNS WITH SEPARATE CABLE
FOR DC POWER AND AUDIO
FOR DC POWER AND AUDIO
For installations where Belden 1502 is not feasible, or for
installations that require cable runs longer than 150 feet, you
can use separate cables for DC power and balanced audio:
a large-gauge cable for DC and a high-quality, balanced
audio cable for audio. The separate cables attach to the
Phoenix connecter at the loudspeaker as shown in the
Figure 4. Cable runs longer than 150 feet for DC power
require cable gauges larger than 18 AWG; for more informa-
tion, see “Cable Lengths and Cable Gauges for UP-4XP
Loudspeakers” on page 13.
