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 reinforce-

ment, frontfill coverage, and delay coverage for under-bal-

cony 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-direc-

tivity, 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 — deliv-

ering 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 propri-

etary 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.

UP-4XP UltraCompact Loudspeaker

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 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

CHAPTER 1: INTRODUCTION

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

Appendix A, “UP-4XP Accessories.” For information on

cable assembly, see Appendix B, “Phoenix and EN3 Cable

Assembly.”

CHAPTER 2: UP-4XP LOUDSPEAKER

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.

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 encoun-

tered 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 loud-

speaker’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-fre-

quency 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 continu-

ous, 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 sys-

tem to achieve the desired SPL without exposing the

loudspeakers to excessive levels and possible over-

heating.

UP-4XP Temperature and Limiting

The UP-4XP LED turns solid yellow when its heat sink tem-

perature reaches 65° C (145° F), indicating the unit is reach-

ing 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 tem-

perature of the heat sink cools to 50°C (122°F), the LED

changes from yellow to green and the limiter threshold

returns to normal.

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 con-

ditions 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 fre-

quency response, cable resistance should be kept to a mini-

mum.

NOTE: For long cable runs, you can use a large

cable gauge for DC power and a separate bal-

anced audio cable for audio. For more information,

see “Long Cable Runs with Separate Cable for DC

Power and Audio” on page 14.

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 pos-

sible with heavier wire gauges (see Table 1 and Table 2).

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).

CHAPTER 2: UP-4XP LOUDSPEAKER

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 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

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 informa-

tion, see “Cable Lengths and Cable Gauges for UP-4XP

Loudspeakers” on page 13.

NOTE: For more information about cable

assembly and pin-outs, see Appendix B,

“Phoenix and EN3 Cable Assembly.”

CHAPTER 3: POWERING UP-4XP LOUDSPEAKERS

CONNECTING UP-4XP LOUDSPEAKERS TO

THE MPS-488HP

EXTERNAL POWER SUPPLY

UP-4XP loudspeakers require a Meyer Sound 48 V DC

external power supply, such the 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 mod-

erate applications that don't drive the loudspeakers to maxi-

mum 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:

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 con-

nectors.

■ 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.

TIP: You can use two separate cables for

UP-4XP loudspeaker connections: a 2-conduc-

tor 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).

EN3 connectors to the MPS-488HPe power supply, use

EN3 5-pin male to EN3 5-pin female cables.

■ To join two EN3 cables, one with an EN3 5-pin male

cable mount connector to one with an EN3 5-pin female

cable mount connector, use an EN3 5-pin female-to-

male cable coupler (PN 28.163.033.01).

CAUTION: Make sure UP-4XP loudspeaker

cables are wired correctly. For details on

assembling loudspeaker cables, see Appendix B,

“Phoenix and EN3 Cable Assembly.”

5. Power on the MPS-488HP and monitor the LEDs on the

front panel to verify connections. For information on the

MPS-488HP LEDs, refer to the MPS-488HP Operating

Instructions.

6. Check the LEDs on the UP-4XP rear panels and verify

they are green (ready to reproduce audio).

7. Enable output from the audio sources (from the mixer or

processor) connected to the MPS-488HP.

UP-4XP OPERATING INSTRUCTIONS

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.

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 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).

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 cradle-

style 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 reli-

ability of any rigging or mounting method for their appli-

cation. 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.

■ 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.

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 adhe-

sive-backed cork washer to the stand (not to the loud-

speaker), and secure the stand to the loudspeaker with the

bolt and washer.

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 manufac-

turer.

CHAPTER 4: QUICKFLY RIGGING

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

The MYA-UP4 mounting yoke suspends a single UP-4XP

loudspeaker and allows a wide range of horizontal and verti-

cal adjustment. The MYA-UP4 is available in two kits: one

with 3/8-16 hardware (PN 40.201.039.01), and one with M10

hardware (PN 40.201.039.02).

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.
