The UP-4XP is available with either a Phoenix™ 5-pin male
or sealed SwitchCraft
®
EN3™ male connector for receiving
balanced audio and DC power. Powering the unit from an
external source eliminates the need for wiring conduits while
still preserving the advantages of self-powered systems.
The UP-4XP's amplifier and signal-processing circuits are
designed to store DC power and tolerate voltage drops,
thereby accommodating light-gauge cables and lengthy
cable runs.
UP-4XP loudspeaker systems require a 48 V DC external
power supply, such as Meyer Sound’s MPS-488HP. The sin-
gle-space 19-inch rack unit receives eight channels of bal-
anced audio from its XLR female Channel Inputs and routes
the audio, along with 48 V of DC power, to its eight Channel
Outputs. The Channel Outputs, which are available as either
Phoenix 5-pin male connectors or SwitchCraft EN3 5-pin
female connectors, can deliver DC power to up to eight
UP-4XP loudspeakers.
Cable lengths up to 150 feet for DC power are possible
when using 18-AWG wire, with just 1 dB of loss in peak SPL.
Longer cable runs are possible for moderate applications
that don't drive the loudspeakers to maximum output, or for
installations with heavier wire gauges. The use of composite
multiconductor cables (such as Belden
®
1502 or equivalent)
allows a single cable to carry both DC power and balanced
audio to the UP-4XPs.
TIP: For complete information on using the
MPS-488HP external power supply, refer to the
MPS-488HP Operating Instructions.
NOTE: The MPS-488HP external power supply
replaces the MPS-488 model, which was origi-
nally designed for use with MM-4XP loudspeakers.
The MPS-488 is also compatible with UP-4XP loud-
speakers and can drive up to four units (using every
other Channel Output).
The UP-4XP's durable cabinet is coated with a black tex-
tured finish and includes top and bottom mounting plates
with 3/8-16 or metric M10 threads. QuickFly mounting
options include the MUB–UP4 U-bracket, MYA–UP4 cradle-
style yoke, and 1 3/8-inch (35 mm) diameter pole-mount
adaptor. Other UP-4XP options include weather protection
(with the sealed EN3 connector) and custom color finishes
for installations and applications with specific cosmetic
