UP-4XP ULTRACOMPACT LOUDSPEAKER
The UP-4XP ultracompact loudspeaker is ideally suited for
applications requiring a small, inconspicuous cabinet that
also delivers high sound pressure levels, low distortion, and
uniform directional control. The self-powered UP-4XP offers
exceptional audio performance in a compact package with
the advantages of a remote power supply. As a standalone
loudspeaker, the UP-4XP can be used for vocal reinforcement, frontfill coverage, and delay coverage for under-balcony applications. The UP-4XP can also be paired with an
optional subwoofer to create a full-range system.

The UP-4XP boasts a wide operating frequency range of
66 Hz to 18 kHz and a maximum peak SPL of 121 dB, with
very low distortion. The unit's high-frequency section
includes a 1-inch metal dome tweeter on a constant-directivity, high-frequency horn with a 100-degree beamwidth.
The low/mid-frequency section includes two 4-inch cone
transducers that work in parallel at low frequencies — delivering a combined acoustic output — with one of the drivers
rolling off at higher frequencies to prevent interference (due
to comb filtering effects) in the crossover region. The proprietary UP-4XP drivers, which are manufactured at Meyer
Sound's factory in Berkeley, California, are powered by three
channels of onboard power amplification that include an
active crossover, driver protection, and frequency and phase
correction circuitry.

CHAPTER 1: INTRODUCTION
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 single-space 19-inch rack unit receives eight channels of balanced 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 originally designed for use with MM-4XP loudspeakers.
The MPS-488 is also compatible with UP-4XP loudspeakers and can drive up to four units (using every
other Channel Output).
The UP-4XP's durable cabinet is coated with a black textured 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 cradlestyle 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

CHAPTER 2: UP-4XP LOUDSPEAKER
The UP-4XP is powered by an external 48 V DC power supply, eliminating the need for wiring conduits while still preserving the advantages of self-powered loudspeaker
systems. The unit's onboard amplifier and signal-processing
circuits were designed to store DC power and tolerate voltage 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 connector is ideal for outdoor, all-weather use. The input connector’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.

UP-4XP with EN3 5-Pin Male Connector
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

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 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.
UP-4XP LED
The UP-4XP has a three-color LED on its rear panel that
changes color to indicate the loudspeaker’s status.
Powering On (Green)
When powering up the UP-4XP loudspeaker, the following
startup events occur and are indicated by the LED:
1. The LED flashes multiple colors during power-up
sequence.
2. After a pause, the LED turns solid green, indicating the
power-up sequence has completed and the loudspeaker
is ready to reproduce audio.
CAUTION: If after the power-up sequence the
LED does not turn solid green (instead flashes
multiple colors or stays solid red) and the UP-4XP
does not output audio, the loudspeaker has encountered an error and may need to be serviced. Contact
Meyer Sound Technical Support.
CAUTION: If after the power-up sequence (or
during operating) the LED turns solid red and
the loudspeaker continues to output audio, the loudspeaker’s voltage may have dropped below 25 V DC.
When encountering these conditions, operation of
the loudspeaker should cease and its power supply
and cabling should be verified.
Limiting (Yellow)
The UP-4XP LED turns yellow to indicate limiting. When the
LED is solid yellow, limiting is engaged for the high-frequency channel. When the LED flashes yellow (on and off),
limiting is engaged for the low-frequency channels. When
limiting is engaged for a channel, its gain is reduced. When
engaged, the limiter protects the loudspeaker’s drivers and
prevents signal peaks from causing excessive distortion in
the loudspeaker’s amplifier, thereby preserving headroom
and maintaining smooth frequency responses at high levels.
When source levels return to normal, below the limiter’s
threshold, the LED turns green and limiting ceases.
The UP-4XP performs within its acoustical specifications at
normal temperatures when the UP-4XP LED is green, or
when limiting is not continuous. If limiting activity is continuous, the loudspeaker is nearing the limits of its operating
capabilities where:
■ Increases to the input level have no effect.
■ Distortion increases due to clipping and nonlinear driver
operation.
■ The drivers are subjected to excessive heat and excur-
sion, which will compromise their life span and may
eventually lead to damage over time.
CAUTION: The UP-4XP LED turns yellow when
the loudspeaker’s signal rises 2 dB above the
limiting threshold, and indicates a safe, optimum level
has been exceeded. If the UP-4XP loudspeakers in a
system begin to limit before reaching the desired
SPL, consider adding more loudspeakers to the system to achieve the desired SPL without exposing the
loudspeakers to excessive levels and possible overheating.
UP-4XP Temperature and Limiting
The UP-4XP LED turns solid yellow when its heat sink temperature reaches 65° C (145° F), indicating the unit is reaching its maximum heat dissipation and a reduction in SPL is
recommended. While the UP-4XP will continue to operate
while the LED is yellow, the limiter threshold is lowered to a
safe level (causing the output level to be lowered by 3 dB) to
prevent the loudspeaker from overheating. When the temperature of the heat sink cools to 50°C (122°F), the LED
changes from yellow to green and the limiter threshold
returns to normal.
12
UP-4XP OPERATING INSTRUCTIONS
!
Clipping (Red)
The UP-4XP turns red when the loudspeaker’s input stage
clips, causing the amplifier to overload. When the LED is
red, the source level should be reduced.
CAUTION: If the UP-4XP LED turns solid red
and the loudspeaker continues to output audio,
though at reduced levels, the loudspeaker’s voltage
may have dropped below 25 V DC. When these conditions are encountered, operation of the loudspeaker
should cease and its power supply and cabling
should be verified.
UP-4XP CURRENT DRAW AND CABLE REQUIREMENTS
Each UP-4XP loudspeaker draws a maximum current of
4.05 A continuous and 4.50 A peak from its external 48 V
DC power supply. The current draw for the UP-4XP is
dynamic and fluctuates as operating levels change. The
cabling between the UP-4XP and its external power supply
adds resistance and hence causes a voltage drop at the
loudspeaker. Because lower DC voltages compromise
amplifier performance (peak SPL), and in some cases frequency response, cable resistance should be kept to a minimum.
Cable Lengths and Cable Gauges for UP-4XP Loudspeakers
Cable lengths up to 150 feet between the UP-4XP and its
external power supply are supported with only 1 dB of peak
SPL loss using 18 AWG wire. Longer cable lengths are possible with heavier wire gauges (see Table 1 and Table 2).

NOTE: For long cable runs, you can use a large
cable gauge for DC power and a separate balanced audio cable for audio. For more information,
see “Long Cable Runs with Separate Cable for DC
Power and Audio” on page 14.
NOTE: The total cable resistance between the
UP-4XP and its external power supply should
not exceed 2 ohms.
Calculating the Maximum Cable Length
The maximum cable length for a UP-4XP can be calculated
with the following formula:
maximum length = 2 ohms / 2 * cable resistance
For example, the maximum length of an 18 AWG cable with
a resistance of 0.00636 is 157.2 feet (2 / 2 * 0.00636).

WIRING UP-4XP LOUDSPEAKER CABLES 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 balanced audio in a single jacket. When wiring UP-4XP loudspeaker 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.

White Balanced audio, positive (+) 22 AWG
Blue Balanced audio, negative (–) 22 AWG
Shield drain Balanced audio, shield 24 AWG
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.
NOTE: For a complete list of cables and cable
connectors available from Meyer Sound that
can be used with the UP-4XP loudspeaker, see
Appendix A, “UP-4XP Accessories.”
LONG CABLE RUNS WITH SEPARATE CABLE 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 information, see “Cable Lengths and Cable Gauges for UP-4XP
Loudspeakers” on page 13.
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 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.
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

assembly and pin-outs, see Appendix B,
“Phoenix and EN3 Cable Assembly.”
CHAPTER 3: POWERING UP-4XP LOUDSPEAKERS
MPS-488HPp
CONNECTING UP-4XP LOUDSPEAKERS TO
THE MPS-488HP
UP-4XP loudspeakers require a Meyer Sound 48 V DC
external power supply, such the MPS-488HP. The singlespace 19-inch rack unit receives eight channels of balanced
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.
To connect UP-4XP loudspeakers to the MPS-488HP:
EXTERNAL POWER SUPPLY
■ When connecting UP-4XP loudspeakers equipped with
Phoenix connectors to the MPS-488HPp power supply,
use Phoenix 5-pin male to Phoenix 5-pin female cables.
1. Power off the MPS-488HP.
2. Connect audio sources (from a mixer or processor) to the
MPS-488HP Channel Inputs. Use balanced XLR cables.
3. Use the MPS-488HP Link switches to route Channel
Inputs to the desired Channel Outputs. For information
on the MPS-488HP Link switches, refer to the
MPS-488HP Operating Instructions.
4. Connect the UP-4XP loudspeakers to the MPS-488HP
Channel Outputs. Use composite cables (such as
Belden 1502 or equivalent) wired for both DC power and
balanced audio and outfitted with the appropriate connectors.
MPS-488HPp with Eight UP-4XP Loudspeakers
TIP: You can use two separate cables for
UP-4XP loudspeaker connections: a 2-conductor cable for DC power and a 3-conductor cable for
balanced audio, both attached to a single Phoenix
connector on each cable end. This allows you to use
a larger gauge for the DC cable so you can achieve
longer cable runs (see “Cable Lengths and Cable
Gauges for UP-4XP Loudspeakers” on page 13).

CONNECTING UP-4XP LOUDSPEAKERS TO THE MPS-488 EXTERNAL POWER SUPPLY
The original MPS-488 was designed for use with the
MM-4XP miniature loudspeaker. While the MPS-488 can
power up to eight MM-4XP loudspeakers, it can only power
up to four UP-4XP loudspeakers (due to the UP-4XP’s
higher power requirements and current draw).
Because the MPS-488 can power a maximum of four
UP-4XP loudspeakers, the loudspeakers should only be
connected to Channel Outputs 1, 3, 5, and 7. Do not use the
even-numbered channel outputs.
MPS-488P Power Supply
NOTE: These guidelines do not apply to the
MPS-488HP external power supply, which can
drive up to eight UP-4XP loudspeakers.
NOTE: The MPS-488HP external power supply
replaces the MPS-488 model, which was originally designed for use with MM-4XP loudspeakers.
The MPS-488 is also compatible with UP-4XP loudspeakers and can drive up to four units (using every
other Channel Output).

CHAPTER 4: QUICKFLY RIGGING
!
The UP-4XP includes top and bottom mounting plates with
3/8-16 or metric M10 threaded nuts. QuickFly mounting
options include the MUB-UP4 U-bracket, MYA-UP4 cradlestyle yoke, and MSA-UPM pole-mount adaptor.
IMPORTANT SAFETY CONSIDERATIONS
When installing Meyer Sound loudspeakers, the following
precautions should always be observed:
■ All Meyer Sound products must be used in accordance
with local, state, federal, and industry regulations. It is
the owner’s and user’s responsibility to evaluate the reliability of any rigging or mounting method for their application. Rigging should only be carried out by
experienced professionals.
■ Use mounting and rigging hardware that has been rated
to meet or exceed the weight being hung.
■ Make sure to attach mounting hardware to the building's
structural components (studs or joists), and not just to
the wall surface. Verify that the building's structure and
the anchors used for the installation will safely support
the total weight of the mounted loudspeakers.
POLE-MOUNTING UP-4XP LOUDSPEAKERS
You can mount the UP-4XP on a third-party loudspeaker
stand with the optional MSA-UPM stand adapter
(PN 40.086.013.01). The MSA-UPM kit includes both 3/8-16
and M10 hardware. To install the adapter, attach the adhesive-backed cork washer to the stand (not to the loudspeaker), and secure the stand to the loudspeaker with the
bolt and washer.
■ Use mounting hardware appropriate for the surface
where the loudspeaker will be installed.
■ Make sure bolts are tightened securely. Meyer Sound
recommends using Loctite
®
on bolt threads and safety
cables.
■ Inspect mounting and rigging hardware regularly. Imme-
diately replace any worn or damaged components.
UP-4XP with MSA-UPM Stand Adapter (Upside Down)
CAUTION: When mounting the UP-4XP on a
pole, make sure the pole has been rated to
support the full weight of the loudspeaker. Observe
all safety precautions specified by the pole manufacturer.

TIP: Meyer Sound offers two kits for mounting
the UP-4XP on top of the UMS-1P subwoofer.
The MPS-UMS pole mount kit (PN 40.086.014.02)
includes a 43-inch (1090 mm), 3/8-inch (35 mm)
diameter pole assembly. The MPK-UMS pole mount
kit (PN 40.086.014.01) includes the same pole
assembly along with the MSA-UPM stand adapter.
MYA-UP4 Mounting Yoke
To install the yoke, attach it to the loudspeaker’s top and
bottom end plates with the included bolts and washers.
Tighten the bottom bolt first and then the top. A “C” or “G”
hanging clamp and steel safety cable (not included) are
required to suspend the MYA-UP4 mounting yoke.
NOTE: The top bar of MYA-UP4 mounting
yoke accommodates hanging clamps with
standard 1/2-inch or 12 mm bolts.

NOTE: Bulk cables use Belden 1502R (regular) or Belden 1502P (plenum) cable. Belden 1502 is a composite
cable comprised of two 18 AWG wires for DC power, two 22 AWG wires for balanced audio, and one 24 AWG
wire for audio shield. This single cable can deliver both DC power and balanced audio to loudspeakers at cable runs
of up to 150 feet with only 1 dB of loss in peak SPL. Longer cable runs are possible with heavier gauges for DC
power and separate cables for balanced audio. For more information, see “UP-4XP Current Draw and Cable
Requirements” on page 13.

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 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.
ASSEMBLING EN3-TO-EN3 LOUDSPEAKER CABLES
When connecting UP-4XP loudspeakers equipped with EN3 connectors to the MPS-488HPe power supply, you need an
EN3 5-pin female to EN3 5-pin male cable. The following procedure documents how to assemble this cable. If you are starting with an EN3-to-pigtail cable, you can skip step 5 in this procedure.
NOTE: Cable mount connectors cannot connect to other cable mount connectors. Cable mount connectors
can only connect to panel mount connectors (like those on the UP-4XP and MPS-488HPe) or inline connec-
tors. To extend cables with EN3 connectors on both ends you can use an EN3 5-pin female-to-male cable coupler.
Assembled EN3-to-EN3 Cable
To assemble an EN3-to-EN3 loudspeaker cable:
1. Disassemble the EN3 5-pin male connector and feed one end of the cable through the boot, cable clamp housing, and
