Introduction

The Integrated Design

The Meyer UM-P Series (UM-100P, UM-1P) self-

powered stage monitors are composed of:

• one 12-inch cone driver and one 3-inch diaphragm

compression driver;

• phase-corrected, optimized control electronics;

• a two-channel amplifier (350 Wrms/ch).

The drivers, control electronics, and amplifier are inte-

grated into a compact enclosure. The UM-P Series is

intended to be used as a stage monitor but can also be

used as a mid-hi and musical instrument speaker.

The UM-1P horn’s narrow beamwidth (45°H x 45°V)

permits precise coverage with minimal interaction be-

tween neighboring monitors. The UM-100P horn’s wide

horizontal beamwidth (100°H x 40°V) addresses a

larger coverage area with fewer speakers.

The UM-P Series, more than a powered version of the

Meyer Ultra-monitor, implements these significant de-

sign improvements:

• The amplifier is optimized for the system, providing

substantial power without endangering the drivers.

• The integrated design simplifies setup and in-

stallation, eliminates amp racks, and extends the

durability and reliability of the loudspeaker.

• The gain structure between the control electronics

and amplifier is perfectly matched.

The UM-P produces flat acoustical phase and amplitude

response, full-range bandwidth, precise imaging, and

exceptional system impulse response.

The UM-P Horns: Constant-Q

In a recent research and development effort, Meyer

Sound solved the most difficult problems associated

with horn design. In order to appreciate the significance

of this work, it is necessary to define an often misunder-

stood term: the beamwidth of a horn is the angle at

which the sound pressure at a given frequency decreases

to half (–6 dB) its on-axis amplitude. Specifying beam-

width using the –6 dB points has been proposed as the

audio industry standard and Meyer Sound adheres to

this definition.

NOTE: Unfortunately, beamwidth is often used to de-

scribe the angle at which the sound pressure decreased

10 dB from its on-axis amplitude because many listeners

perceive this as a decrease to half the SPL. When reading

a beamwidth specification, it is essential to determine

whether it refers to the 6 or 10 dB points because they

indicate very different results: the 10 dB points yield a

wider angle.

Previous technologies produced horns whose beamwidth

varied over the operating frequency range. These horns

also displayed nonuniform frequency response within,

and significant side lobe energy outside their beamwidth.

Both undesirable characteristics, particularly prevalent

for horns with a wide beamwidth, make array design

extremely uproblemactic

The UM-P was developed in Meyer Sound’s anechoic

chamber by measuring coverage patterns using angular

and frequency resolutions of 1° and 1¦36 octave, respec-

tively. The UM-P horns exhibit constant-Q: the beamwidth

remains consistent across the horn’s operating frequency

range in both the vertical and horizontal planes.

Both horns share the following remarkable attributes:

• uniform frequency response within the beamwidth

• rapid and uniform amplitude attenuation for all

frequencies outside the beamwidth

• minimal side lobes

AC Power

The UM-P uses a PowerCon locking 3-pole AC mains

connector that prevents inadvertent disconnection. The

unit must have the correct power cord for the AC power

in the area in which it will be used.

When AC power is applied to the UM-P, an Intelligent

ACtm supply automatically selects the correct operating

voltage, allowing the UM-P to be used internationally

without manually setting voltage switches. The Intelligent

AC supply performs the following protective functions

Engagement

Separation

to compensate for hostile conditions on the AC mains:

• suppresses high voltage transients up to several

kilovolts

• filters EMI (radio frequencies and noise present

on the AC line)

• sustains operation during low-voltage periods,

which minimizes audio discontinuity

• provides soft-start power-up, which eliminates

high inrush current

The UM-P can withstand continuous voltages up to

264V and allows any combination of voltage to GND

(i.e. Neutral-Hot-GND, Hot-Hot-GND). Continuous

voltages higher than 264V may damage the unit.

Voltage Requirements

The UM-P operates safely and without audio disconti-

nuity if the AC voltage stays within the range 88–264V,

47–63 Hz. After applying AC power, the system is muted

while the circuitry charges up and stabilizes. After two

seconds, the On/Temp. LED on the user panel illumi-

nates green, the system unmutes and is ready to pass

audio signals. If the On/Temp. LED does not illuminate

or the system does not respond to audio input after ten

seconds, consult the Troubleshooting section.

The UM-P’s power supply uses stored energy to continue

functioning for about 10 AC cycles if the voltage decreases

below 88V (a condition known as brownout). The precise

length of time the unit functions during brownout

depends on the operating level and how low the voltage

drops. The unit turns off if the voltage does not increase

above 88V before the storage circuits are depleted. If

the UM-P shuts down due to brownout, the power

supply automatically turns on after three seconds if the

voltage returns to the normal operating range. If the

UM-P does not turn back on after ten seconds, consult

the Troubleshooting section.

NOTE: We recommend that the supply be operated at

least a few volts away from the upper and lower bounds

of the operating range to avoid possible shutdown.

Current Requirements

Each UM-P requires approximately 3Arms @115V

(1.5Arms@230V) for proper operation, allowing up to

five UM-Ps to be powered from one 15A circuit. How-

ever, we recommend powering no more than three UM-Ps

per 15A branch to allow a 30% margin for peak voltages.

The UM-P presents a dynamic load to the AC mains

which causes the amount of current to fluctuate be-

tween quiet and loud operating levels. This affects the

number of UM-Ps that can be used for a given breaker

type. Since different types of cables and circuit breakers

heat up and trip at varying rates, it is essential to

understand the types of current ratings and how they

correspond to circuit breaker and cable specifica-

tions.

The maximum continuous RMS current is the maximum

RMS current over a duration of at least 10 seconds. It is

used to calculate the temperature increase in cables,

which is used to select cables that conform to electrical

code standards. It is also used to select the rating for

slow-reacting thermal breakers.

The maximum burst RMS current is the maximum

RMS current over a one second duration. It is used to

select the rating for most magnetic breakers.

The maximum instantaneous peak current during burst

is used to select the rating for fast-reacting magnetic

breakers and to calculate the peak voltage drop in long

AC cables according to the formula

Vpkdrop = Ipk x Rtotal cable

Use the table below as a guide to select cables and circuit

breakers with appropriate ratings for your operating

voltage.

To determine the minimum total service power re-

quired by a system of UM-P, or other Meyer self-pow-

ered speakers, add their maximum continuous RMS

currents together. We recommend allowing an addi-

tional 30% above the minimum amperage to prevent

peak voltage drops at the service entry and nuisance

tripping.

Power Connector Wiring

Use the following AC cable wiring diagram to create

international or special-purpose power connectors:

brown = hot

blue =

neutral

yellow/green =

earth ground

(chassis)

AC cable color code

If the colors referred to in the diagram don't correspond

to the terminals in your plug, use the following guide-

lines:

• Connect the blue wire to the terminal marked

with an N or colored black.

• Connect the brown wire to the terminal marked

with an L or colored red.

• Connect the green and yellow wire to the terminal

marked with an E (or ) or colored green (or

green and yellow).

Safety Issues

Do not use a ground-lifting adapter or cut the AC

cable ground pin.

Keep all liquids away from the UM-P to avoid hazards

from electrical shock.

Do not operate the unit with worn or frayed cables;

replace them immediately.

If the UM-P will be installed outdoors contact Meyer

Sound for information about the rain hood and weather

protection for the drivers and electronics.

While a single UM-P can be hung by its handle bars, do

not hang any additional weight from the cabinet. UM-P

handle bars are not designed to support heavy rigging

loads.

The Modular Rear Panel

The rear panel of the UM-P has two slots for processor

modules. The top slot contains the Audio Input and

Control Module; the bottom slot contains the optional

Remote Monitoring System™ (RMS) Module. A blank

plate covers the bottom slot if RMS is not installed. For

drawings of these modules, see page 13.

Audio Input

There are three, interchangeable Audio Input and Control

Modules with optimized connectors and controls for

different applications. Each module has a 24V Fan

connector to power an optional fan (see page 7).

Each module uses a three-pin, female XLR audio input

connector with a 10 kΩ balanced input impedance wired

with the following convention:

Pin 1 — 220 kΩ to chassis and earth ground (ESD clamped)

Pin 2 — Signal

Pin 3 — Signal

Case — Earth (AC) ground and chassis

Pins 2 and 3 carry the input as a differential signal. Use

standard audio cables with XLR connectors for balanced

signal sources. A single audio source can drive multiple

UM-Ps with a paralleled input loop, creating an unbuf-

fered hardwired loop connection, with negligible loss

in signal level. For example, since the input impedance

of one UM-P is 10 kΩ, looping 20 UM-Ps produces a

balanced input impedance of 500Ω. With a 150Ω audio

source, the 500Ω load results in only a 2.28 dB loss.

Looping Audio Input Module

This standard module uses a balanced, female XLR

connector for audio input and a male XLR loop connector

to interconnect multiple speakers. The audio input

connector is hardwired with pin 2 hot to comply with

audio industry standards. The loop connector, wired in

parallel to the audio input, transmits the input signal if

the UM-P is turned off for any reason.

Summing Audio Input Module

This module has a balanced, female XLR connector for

audio input but has, instead of a loop connector, a

second female XLR connector that functions as a summing

input. Applying a signal to one of the inputs results in a

normal signal level. Utilizing both summing inputs

creates a correctly summed mono signal with each input

6 dB below the level of a single input. This is an effective

method for distributing both sides of a stereo signal to

a single UM-P without requiring external level control.

Differential Inputs

Looping, Polarity, and Attenuating Audio

Input Module

This module has a balanced, female XLR audio input

connector, a male XLR loop connector, an input polarity

switch, and a level attenuator knob. With the input

polarity switch in the up (+) position, pin 2 is hot

relative to pin 3, resulting in a positive pressure wave

when a positive signal is applied to pin 2. With the

switch down (–), pin 3 is hot relative to pin 2, resulting

in a negative pressure wave when a positive signal is

applied to pin 2. The level attenuator knob operates

between 0 dB (no level attenuation) in a fully clock-

wise position to –12 dB in a fully counter-clockwise

position.

Remote Monitoring System

The UM-P can be equipped to operate with the Remote

Monitoring System (RMS) network and software ap-

plication. RMS displays signal and power levels, driver

and cooling fan status, limiter activity, the state of the

polarity switch, attenuator level, and amplifier tem-

perature for all speakers in the network on a Windows-

based PC. RMS is an excellent field-diagnostic tool that

removes the guesswork from troubleshooting during a

performance. All Meyer RMS-compatible speakers use

the same RMS module so they can be easily exchanged

between speakers (depicted on back page). Installing an

RMS module requires only a Phillips screwdriver.

Contact Meyer Sound for more information about RMS.

Amplification, Limiting, and

Cooling System

Amplification and Limiting

Each driver in the UM-P is powered by one channel of a

proprietary Meyer Sound amplifier utilizing comple-

mentary power MOSFET output stages (class AB, bridged,

350 Wrms/ch). Each channel has a limiter that prevents

driver over-excursion and regulates the temperature of

the voice coil. The limiters protect the drivers without

the glaring compression effects imposed by typical

limiters, allowing high SPLs across each driver’s entire

frequency range. Limiter activity for the high and low

channels is indicated by two yellow Limit LEDs on the

rear panel (the high limit is above the low limit LED).

The UM-P performs within its acoustical specifications

and operates at a normal temperature if the limit LEDs

are on for no longer than two seconds, and off for at

least one second. If either LED remains on for longer

than three seconds, that channel incurs these negative

consequences:

• Increasing the input level will not increase the

volume.

• The system distorts due to clipping and nonlinear

driver operation.

While the UM-P limiters fully protect the system under

overload conditions and exhibits smooth sonic charac-

teristics, we recommend that you do not intentionally

drive the UM-P into continuous limiting to attain com-

pression effects.

For applications where large amounts of compression

are required, we recommend using an outboard com-

pressor/limiter for greater control of limit and com-

pressor effects.

Amplifier Natural Convection Cooling System

The UM-P employs a natural convection cooling sys-

tem that depends on air flow from below the cabinet

over the heatsink. Allow for proper ventillation of

fresh air when using the speaker.

If the temperature of the heatsink reaches 85°C (185°F),

the On/Temp. LED on the rear panel turns from green

(On) to red (Temp.) and the limiter threshold is lowered

to a safe level to prevent the amplifiers from overheat-

ing. Under high temperature conditions the limiter

threshold is reduced to 6 dB. When the heatsink tmeperature

decreases to 75°C (167°F), the On/Temp. LED changes

from red to green and the limiter threshold returns to

normal.

! The heatsink gets too hot to touch during normal

operation. Use extreme caution when approaching the

rear of the cabinet.

Fan Assembly Kit

While convection cooling is adequate for most appli-

cations, driving the UM-P into frequent limiting under

severe temperature conditions, or where ventilation is

restricted, an optional fan kit is available to maintain a

safe operating temperature:

The easy-to-install fan, powered by the 24V Fan rear

panel connector, blows air directly onto the heatsink.

The fan speed increases as the heatsink temperature

rises, which maintains a safe operating temperature

with minimal fan noise. Contact Meyer Sound to order

the fan kit.

Power Supply Fan

The power supply is cooled by a single small internal

fan that turns on low when the unit is first powered up.

The fan doubles its speed as the system is driven with

audio. Since the fan draws air in from, and exhausts it

out the side of the cabinet, there must be at least six

inches on the amplifier’s side of the cabinet and ad-

equate air flow.

UM-P Applications

In half-space loading condition, the UM-P will typically

produce a maximum SPL of 135 dB at 1 meter with a

frequency response down to 60Hz, which is perfect for

vocals and most instruments. When using the UM-P in

most applications that require SPL in the sub harmonic

frequencies, such as monitoring drums and bass, the

UM-P should be supplemented with a subwoofer such

as the Meyer USW-1P or 650-P depending on the needs

of the end user. For ideas on integrating the UM-P with

other Meyer Sound products contact Meyer Sound Technical

Support.

The Constant Q design of the horn allows frequencies

outside of the coverage area of the speaker to attenuate

quickly. This is excellent for monitoring where several

different monitors are used in close proximity. When

placing the monitor carefully consider the coverage

pattern of the UM-P and UM-100P.

The UM-1P’s coverage area is:

–6 dB points: 45° H x 45° V

–10 dB points: 65° H x 65° V

The UM-100P’s coverage area is:

–6 dB points: 100° H x 40° V

–10 dB points: 120° H x 60° V

The following drawings illustrate the coverage area of

each horn from three different perspectives in order to

depict the three dimensional coverage pattern.

Verifying Polarity

Incorrect driver polarity impairs system performance

and may damage the drivers. All Meyer Sound loud-

speakers are shipped with the drivers in correct align-

ment.

If the driver or circuit wiring has been removed or

disassembled it is essential to check the polarity between

adjacent monitors and between drivers and between

adjacent loudspeakers.

Polarity in Adjacent Loudspeakers

Use the following test procedure to verify the polarity

between two adjacent loudspeakers of the same type:

1. Position two loudspeakers adjacent to each other.

2. Place a measurement microphone 3ft. from the

speakers and 3 to 4 feet above the UM-1Ps, on the

axis between the speakers.

3. Connect a signal source to one speaker and note

the frequency response and overall level.

4. Apply the same signal to the second speaker with

the first speaker still connected.

The polarity is correct if the frequency response remains

constant with a 5-6 dB SPL increase in amplitude.

Broadband cancellation (decreased overall level) in-

dicates polarity reversal.

Since polarity reversal causes excessive driver ex-

cursion at high source levels, use moderate levels

when conducting these tests.

Driver Polarity in the Same UM-P

Use the following test procedure to verify polarity

between drivers in the same loudspeaker:

1. Place a monitoring microphone 1 meter from the

front of the loudspeaker at the midway point be-

tween the high and low frequency drivers.

2. Connect a full range signal to the loudspeaker and

note the frequency response.

The polarity is correct if the frequency response is smooth

through the crossover region (800Hz to 1.5kHz). Can-

cellation of 6dB or more in this region indicates polarity

reversal.

Troubleshooting

This section suggests several possible solutions to some

common problems encountered by UM-P users and is

not intended to be a thorough troubleshooting guide.

Qualified electronics technicians with access to a test

bench can request the following documents from Meyer

Sound: Troubleshooting Guide, The Low Frequency

Driver Replacement Procedure, and The High Frequency

Driver Replacement Procedure for the UM-1P/100P.

The On/Temp. LED does not illuminate,

there is no audio, and the power supply

fan is off.

1. Make sure the AC power cable is the correct type

for the regional voltage and that it is securely

connected to the AC inlet then unplug and recon-

nect the AC cable.

2. Use an AC voltmeter to verify that the AC voltage

is within the ranges 88–264V, 47–63 Hz.

3. Call Meyer Sound Technical Support.

The On/Temp. LED is illuminated but there

is no sound.

1. Verify that the audio source (mixer, EQ, delay) is

sending a valid signal.

2. Make sure the XLR cable is securely fastened to the

XLR audio input connector.

3. Verify that the XLR cable is functioning by substi-

tuting another cable or by using the cable in ques-

tion in a working system.

4. Send the audio signal to another speaker to insure

signal presence and that the level is within the

proper range. Turn the source level down before

reconnecting the audio input and increase the level

slowly to avoid a sudden blast of sound.

5. If possible, monitor the audio source with headphones.

Hum or noise is produced by the speaker.

1. Disconnect the audio input. If the hum ceases, the

noise originates somwhere earlier in the signal

path. If the noise persists, the problem is within the

UM-P. In this case return the unit to the factory or

nearest authorized service center.

2. Make sure the XLR cable is securely fastened to the

XLR audio input connector.

3. Send the audio signal to another speaker to insure

signal presence and that the level is within the

proper range. Turn the source level down before

reconnecting the audio input and increase the level

slowly to avoid a sudden blast of sound.

5. Hum or noise can be produced by a ground loop.

Since the UM-P is effectively ground-lifted, this

should not occur unless grounds are extremely

different voltages.

The audio produced by the speaker is

distorted or compressed but the limit light

is not illuminated.

1. Make sure the XLR cable is securely fastened to the

XLR audio input connector.

2. Send the audio signal to another speaker to insure

that the level is within the proper range. Turn the

source level down before reconnecting the audio

input and increase the level slowly to avoid a

sudden blast of sound.

3. Monitor the audio source with headphones.

The audio produced by the speaker is

highly compressed and the limit light is

constantly yellow.

1. Turn down the level of the input signal to the

speaker system.

Only the high or low driver seems to pro-

duce sound.

1. Make sure the audio signal is full-range and has

not been filtered in a previous stage of the signal

chain. If possible, monitor the audio source with

high-quality headphones.

2. Send the audio signal to another speaker to insure

that the signal is full-range. Turn the source level

down before reconnecting the audio input and

increase the level slowly to avoid a sudden blast of

sound.

3. Use a sine wave and/or pink noise generator to

send a variety of frequencies to the speaker.

There is some sound but the On/Temp.

LED turns from green to red.

This occurs when the heatsink temperature reaches 85°C

(185°F), indicating that the amplifier is thermally over-

loaded. The limiter threshold has dropped to a safe

level, so the audio level is probably reduced.

1. Make sure there is enough clearance above, below,

and behind the unit.

2. Make sure there is sufficient air flow around the

unit.

3. Avoid exposing the heatsink to direct sunlight if

the ambient temperature is high.

4. If the ambient temperature is greater than 30°C

and this condition occurs frequently, contact Meyer

Sound to order the optional Fan Kit.

See the section Amplification, Limiting, and Cooling

System on page 6 for a complete discussion about the

cooling system.

There is no sound, the On/Temp. LED is

dim or off, and the power supply fan is on

high speed.

This extremely rare event occurs when the power supply

overheats, causing a 1-2 minute interruption in operation.

The unit turns on again when the power supply has

cooled sufficiently.

1. Make sure there is at least six inches clearance

behind the unit.

2. Make sure there is sufficient air flow around the

unit.

3. Avoid exposing the unit to direct sunlight in high

ambient temperature.

See the section Amplification, Limiting, and Cooling

System on page 6 for a more information about the

power supply’s internal fan and cooling system.
