HOW TO USE THIS MANUAL
As you read this manual, you’ll find figures and diagrams
to help you understand and visualize what you’re reading.
You’ll also find icons that flag important information or warn
you against improper or potentially harmful activities. These
icons include:
A NOTE identifies an important or useful
piece of information relating to the topic
under discussion.
A TIP offers a helpful tip relevant to the topic
at hand.
A CAUTION gives notice that an action can
!
have serious consequences and could cause
harm to equipment or personnel, delays, or other
problems.
In standalone under-balcony, front- or side-fill applications,
UPM-1P and UPM-2P loudspeakers can provide vocal
range reinforcement as a small PA system, while a full-range
system can be created with the addition of a separate subwoofer. Other features include:
Extremely low distortion
Uniform directional control on both the horizontal and
vertical axes
Dual 5-inch low-mid transducers
1-inch metal dome high-frequency driver on constant
directivity symmetrical horns
Two-channel power amplifier
Proprietary phase-corrected active processing circuitry
Both the UPM-1P and UPM-2P use a 1-inch metal dome
tweeter on a symmetrical constant-directivity high-frequency horn. With its 45-degree beamwidth, the UPM-2P loudspeaker produces a narrow, symmetrical pattern for precise
coverage control, while the UPM-1P loudspeaker offers a
wider 100-degree symmetrical coverage pattern for broad
listening areas.
INTRODUCING THE UPM-1P AND UPM-2P
LOUDSPEAKERS
Meyer Sound’s UPM-1P ultra-compact wide coverage and
UPM-2P ultra-compact narrow coverage loudspeakers are
self-powered professional sound reinforcement loudspeakers made for applications that require a small, inconspicuous system capable of high sound pressure levels.
Optimized Control Electronics
Like all Meyer Sound self-powered loudspeakers, the
UPM-1P and UPM-2P exhibit superior performance across
virtually all parameters. Because the amplifiers and control electronics are precisely optimized for each driver, the
overall system is able to produce more power with flatter
response and lower distortion. Self-powering also means
simplifying installation by eliminating amplifier racks and
external drive processing — allowing configuration of
extensive distributed systems free from the signal losses
imposed by long loudspeaker cable runs or 70/100-volt
wiring schemes. The UPM-1P and UPM-2P loudspeakers
also include a laser-trimmed differential input stage for high
common mode rejection, and can be equipped with Meyer
Sound’s RMS™ remote monitoring system.

INTRODUCTION
Three-Way System
Unlike similar conventional systems, the UPM-1P and UPM2P loudspeakers are three-way systems. In the pass band
below 320 Hz, where greater power handling and cone area
are needed, the 5-inch drivers are driven together in parallel.
However, above 320 Hz a high-pass filter rolls off the signal
going to one of the drivers, so only one of the two drivers reproduces the critical mid frequencies close to the crossover
frequency. Since power requirements are drastically lower
in this region, there is no loss in response. and a remarkably
uniform response at all frequencies along all axes — horizontal, vertical and diagonal.
NOTE: In conventional two-way designs
both low-mid drivers reproduce the same
information throughout their operating range. At
low frequencies this is not an issue, since the
wavelengths (500 Hz, about two feet) are longer
than the distance between the center points of the
two cones. But at around 1 kHz, problems arise
in the off-axis vertical response of the system.
As the wavelengths of critical mid frequencies
approach the distance between loudspeaker
centers, significant comb filtering effects appear.
These “holes” can be quite severe. In applications
where such a loudspeaker is mounted vertically
and the audience area is contained entirely within
a 50-degree vertical arc, sharp off-axis attenuation
may not be detrimental. However, if you flip the
cabinet on its side to use it as an under-balcony
loudspeaker, you will experience serious difficulties.
The UPM-1P and UPM-2P loudspeakers provide a more
elegant solution, with an active crossover distributing the
signal between the low- and high-frequency sections, and
a simpler 2-way passive crossover that is employed to
implement the single-point midrange solution. In addition, a
sophisticated phase correction circuit in the active electronics compensates for phase shift in the passive network. The
result is a significantly better system impulse response, and
better imaging when UPM-1P and UPM-2P loudspeakers
are used in stereo or multi-channel applications.
APPLICATIONS
The UPM-1P and UPM-2P loudspeakers are designed
to be used in a wide variety of applications in sound
reinforcement, as well as music playback and monitoring.
In theatre sound design, the UPM-1P and UPM-2P
loudspeakers may be used as fill as well as a standalone effects loudspeaker system for surround, onstage
effects and anywhere a compact device is required. For
example, equally spacing UPM-1P loudspeakers across the
downstage edge or under a balcony offers very accurate
audio reproduction for theatre design (Figure i.3).
UP M-1 P
Figure i.3: UPM-1Ps arranged across a downstage edge
The UPM-1P loudspeaker’s wide 100-degree pattern is
designed to keep sound from being too localized, allowing
for more even SPL distribution across seats near to the
stage or any other areas the loudspeaker is intended to
cover. For more focused directional control, the UPM-2P’s
45-degree beamwidth produces a narrow, symmetrical
pattern to accommodate ultra-precise design requirements.
The 123 dB peak SPL of the UPM-1P and UPM-2P
loudspeakers makes them an excellent choice for use as
fill in sports facilities. They can be used in stadiums and
arenas as upper level delay loudspeaker or under upper
level overhangs, as well as in suites and box seats that fall
out of the main system’s direct path.
The UPM-1P and UPM-2P loudpseakers also work
as stand-alone PA systems for accurate spoken word
reproduction and, with the addition of a companion
subwoofer, a small music reinforcement system.
In addition, because of the flatter phase and frequency
response of Meyer Sound UltraSeries loudspeakers, the
UPM-1P and UPM-2P loudspeakers can be ideal for high
definition music monitoring when used with a subwoofer.
The wide-coverage UPM-1P loudspeaker provides better
imaging in stereo and 5.1 playback applications, while
the narrower UPM-2P gives you the flexibility to localize
coverage in the near field.

Available QuickFly® rigging accessories— including a
mounting yoke (MYA-UPM), stand adapter (MSA-UPM) and
U-bracket (MUB-UPM)— attach easily to the UPM-1P and
UPM-2P allowing them to be mounted or flown, either as a
single cabinet or in arrays. The optional RMS remote monitoring system module allows comprehensive monitoring of
all key system parameters on a remote RMS host PC.
NOTE: Read this entire manual carefully be-
fore configuring and deploying a UPM-1P or
UPM-2P system. In particular, pay careful attention
to the sections about safety issues.

CHAPTER 1: POWER REQUIREMENTS
CHAPTER 1
Self-powered and compact, UPM-1P and UPM-2P
loudspeakers combine advanced technology with equally
advanced power capabilities. Understanding power
distribution, voltage and current requirements, as well as
electrical safety issues, is critical to the safe operation of
the loudspeakers.
AC POWER
UPM-1P and UPM-2P loudspeakers use a PowerCon®
three-pole AC mains system with locking connectors
to prevent accidental disconnection. They may also be
daisy-chained by using the grey connector (Figure 1.1)
to loop units together. The blue connector serves as the
power input; to loop additional units, simply attach a cable
from the grey connector of the first loudspeaker system to
the blue connector of the second, and so on. One cablemount loop-out grey connector is shipped with the unit.

Voltage Selection
Two versions of both the UPM-1P and UPM-2P
loudspeakers are available: a switchable 115/230-volt and
a non-switchable 100-volt version. The non-switchable
100-volt version will operate properly when receiving
between 87 and 113 volts; the switchable version requires
you to check the voltage switch and set it to either 115 or
230 volts. When set to 115 volts, the UPM-1P and UPM-2P
will operate properly when the AC remains within the range
of 105 to 130 volts. If set to 230 volts, the unit operates
safely and without audio discontinuity within the range of
210 to 264 volts. Operating outside these ranges or with
the voltage switch set improperly could damage the unit.
CAUTION: To avoid damage to the unit,
check the AC voltage selector switch
(Figure 1.2) on the user panel before plugging in
the unit and applying power. Set the switch to
local AC voltage. Always unplug the power cord
before changing the voltage selector switch.
AC Input 115 / 230V~
Figure 1.1. You can daisy-chain UPM-1P and UPM-2P loudspeakers
using the grey connector.
CAUTION: Do not loop more than four
UPM-1P or UPM-2P loudspeakers from the
loop out connector when driven at 115 volts and
not more than eight when driven at 230 volts.
CAUTION: Ensure that you select the
correct power plug for the AC power in the
area in which you use your loudspeaker.
The power supply suppresses high voltage transients up
to several kilovolts and also filters EMI (radio frequencies
and noise present) on the incoming AC voltage. The UPM1P can withstand continuous voltages up to 264 volts and
allow any combination of voltage to GND (that is neutralline-ground or line-line-ground).
CAUTION: Continuous voltages higher
than 265 volts may damage your UPM-1P
or UPM-2P loudspeaker.

CHAPTER 1
!
If voltage drops below the low boundary of its safe
operating range (brownout), the UPM-1P or UPM-2P
loudspeakers use stored energy to continue functioning
briefly, and shut down only if voltage does not rise above
the low boundary before storage circuits are depleted.
How long the loudspeaker will continue to function during
brownout depends upon the amount of voltage drop and
the audio source level during the drop.
If the voltage increases above the upper boundary of either
range, the power supply may be damaged.
NOTE: It is recommended that the supply
be operated in its rated voltage window at
least a few volts away from the turn on/off points.
This ensures that that AC voltage variations from the
service entry – or peak voltage drops due to cable
runs – do not cause the amplifier to cycle on and off
or cause damage to the power supply.
Current Requirements
The UPM-1P and UPM-2P loudspeakers require
approximately 3 amps rms max at 115 volts AC for proper
operation. This allows up to five loudspeakers to be
powered from one 15-amp breaker.
The UPM-1P and UPM-2P loudspeakers present a dynamic
load to the AC mains, which causes the amount of current
to fluctuate between quiet and loud operating levels. Since
different cables and circuit breakers heat up at varying
rates, it is essential to understand the types of current
ratings and how they correspond to circuit breaker and
cable specifications.
The maximum long-term continuous current is the
maximum rms current during a period of at least ten
seconds. It is used to calculate the temperature increase
in cables, in order to select a cable size and gauge that
conforms to electrical code standards. It is also used to
select the rating for slow-reacting thermal breakers.

Make sure that even with the AC voltage drop the
AC voltage always stays in the operating window.
The minimum electrical service amperage required by
UPM-1P and UPM-2P systems is the sum of each
loudspeaker’s maximum continuous rms current. An
additional 30 percent above the minimum amperage is
recommended to prevent peak voltage drops at the service
entry.

trips, always replace a fuse with the same
Power Connector Wiring
The UPM-1P and UPM-2P loudspeakers require a grounded
outlet. It is very important that the system be properly
grounded in order to operate safely and properly. Use the
AC cable wiring diagram shown in Figure 1.3 to create
international or special-purpose power connectors.
The burst current is the maximum rms current during a
period of approximately one second, used to select the
rating of most magnetic breakers and to calculate the peak
voltage drop in long AC cables according to the formula:
V pk (drop)= I pk x R (cable total)
The ultimate short-term peak current is used to select the
rating of fast reacting magnetic breakers.
Use Table 1.1 below as a guide when selecting cable gauge
size and circuit breaker ratings for your operating voltage.
