THE UPQ-D SERIES LOUDSPEAKER

Meyer Sound’s UPQ-D Series loudspeakers evolved from
the UPQ-1P and UPQ-2P product line, optimized using the
advanced amplifier and processing technology that made
the LEO® family an award-wining product line. The series
includes the following loudspeakers:

• UPQ-D1, which has a Constant-Q horn with

-6 dB points at 80° horizontal x 50° vertical
(-10 dB points at 100° horizontal x 60° vertical)

• UPQ-D2, which has a narrow symmetrical coverage and

a Constant-Q horn with -6 dB points at 50° x 50°
(-10 dB points at 60° x 60°)

• UPQ-D3, which has a wide symmetrical coverage and a

Constant-Q horn with -6 dB points at
80° horizontal x 80° vertical
(-10 dB points at 100° horizontal x 100° vertical)

All of the UPQ-D series feature:

• An innovative, highly efficient Class D amplifier with

reduced current draw that reproduces any sound with
linearity over a wide dynamic range

• Optimized frequency and phase response

characteristics

• Lightened cabinet weight

• A redesigned cabinet that retains the original size, grille

frame, and rigging options of previous UPQ products

Each UPQ-D Series loudspeaker offers extremely consistent
polar response and gentle coverage rolloffs that extend
uniformly out to their 10 dB points. The smooth and
consistent performance of all the horns is the result of
advanced computer modeling combined with meticulous
research in Meyer Sound’s anechoic chamber. They also
exhibit remarkably consistent beamwidth in both the
horizontal and vertical planes. The UPQ-D Series horns
deliver uniform attenuation for all frequencies outside the
specified beamwidths.

In addition to the Constant-Q horn, the loudspeakers each
feature one low frequency 15-inch neodymium magnet cone
driver and one 4-inch diaphragm compression driver, both
designed and manufactured at Meyer Sound’s Berkeley,
California headquarters. The UPQ-D1 and UPQ-D3 are
suitable for a range of sound reinforcement applications
including as front-of-house main loudspeakers in small- to
mid-sized venues, or as fill loudspeakers in larger systems.

9

CHAPTER 1: INTRODUCTION

The UPQ-D2 offers a focused beamwidth, which yields
precise coverage and minimal interaction with walls and
neighboring loudspeakers in arrays. This feature makes it an
ideal solution for small to mid-sized venues, houses of
worship, theaters, and nightclubs, as either a stand-alone
loudspeaker or as part of an array.

INTEGRATED AMPLIFIER AND PROCESSING

The proprietary two-channel, class D power amplifier yields
a total power output of 2250 W. Audio input routes through
electronic crossover and correction filters, as well as
through driver-protection circuitry. Phase-corrected
processing ensures a flat acoustical amplitude and phase
response, resulting in an exceptional impulse response and
precise imaging.

Each amplifier channel has sophisticated limiters that are
easily monitored with the limit LEDs on the unit’s rear panel.
The UPQ-D Series modular amplifier and processing
electronics incorporate Meyer Sound’s IntelligentAC™
power supply which adapts to any power voltage worldwide
and provides soft turn on and transient protection. The
UPQ-D Series use XLR 3-pin female input with male loop
output connectors.

The optional RMS™ remote monitoring system module
provides comprehensive monitoring of loudspeaker
parameters from a host computer running Compass
software. An optional XLR 5-pin connector is available to
accommodate both balanced audio and RMS signals.

®

TOTAL SYSTEM APPROACH

The UPQ-D Series loudspeakers integrate seamlessly with
other Meyer Sound products. With compatible acoustical
and performance characteristics and dedicated QuickFly
rigging hardware, the UPQ-D Series loudspeakers and other
Meyer Sound self-powered loudspeakers can provide
everything needed to design and implement systems for
optimum performance in venues of any size or shape.

TIP: Meyer Sound MAPP™ acoustical

prediction software allows for quick
determination of the coverage, frequency response,
impulse response, and maximum linear, undistorted
output of Meyer Sound loudspeakers. It also provides
useful rigging information.

In addition to smooth integration with other Meyer Sound
loudspeakers, the UPQ-D Series loudspeakers can be
supplemented with Meyer Sound subwoofers for extended
low-frequency bandwidth and headroom. UPQ-D Series
systems can be deployed in combination with the 750-LFC
very compact low-frequency control element (Figure 1),
extending the system frequency response down to 35 Hz, or
the 900-LFC compact low-frequency control element
(Figure 2), which supports frequencies down to 30 Hz.

RIG-READY

The UPQ-D1/D2/D3 loudspeakers provide extremely high
power output with low distortion in vented two-way
enclosures. The durable trapezoidal enclosures have a
slightly textured black finish, an integral stand mount
receptacle, and versatile rigging end plates. Made of
heavy-duty, high-strength, corrosion-resistant 6061T6
aluminum, the end plates incorporate threaded M10
attachment points.

QuickFly
array plate and MYA-UPQ mounting yoke. UPQ-D Series
loudspeakers are available in custom color finishes, allowing
them to blend in with any environment. Weather-protected
versions with treated-wood enclosures and a rain hood to
safeguard the rear of the loudspeaker and connectors from
the elements are also available.

The UPQ-D Series loudspeakers combine advanced
loudspeaker technology with equally advanced power
capabilities. Understanding power distribution, voltage and
current requirements, and electrical safety guidelines is critical
for the safe operation of the UPQ-D Series loudspeakers.

AC POWER DISTRIBUTION

All components in an audio system (self-powered
loudspeakers, mixing consoles, and processors) must be
properly connected to an AC power distribution system,
ensuring that AC line polarity is preserved and that all
grounding points are connected to a single node or common
point using the same cable gauge (or larger) as the neutral and
line cables.

CAUTION: Make sure the voltage received by

the UPQ-D Series loudspeakers remain within
their 90–264 V AC operating range. In addition, the
ground line must always be used for safety reasons and
the line-to-ground voltage should never exceed
250 V AC (typically 120 V AC from line to ground).

CAUTION: Before applying AC power to any

Meyer Sound self-powered loudspeaker, make
sure that the voltage potential difference between the
neutral and earth-ground lines is less than 5 V AC when
using single-phase AC wiring.

120 V AC, 3-Phase Wye System (Single Line)

Line-Neutral-Earth/Ground

Figure 3 illustrates a basic 120 V AC, 3-phase Wye distribution
system with the loudspeaker load distributed across all three
phases and with each loudspeaker connected to a single line
and common neutral and earth/ground lines. This system
delivers 120 V AC to each loudspeaker.

Line-Line-Earth/Ground

Figure 4 illustrates a 120 V AC, 3-phase Wye distribution
system with each loudspeaker connected to two lines and a
common earth/ground line. This configuration is possible
because the UPQ-D Series tolerate elevated voltages from the
ground line and does not require a neutral line. This system
delivers 208 V AC to each loudspeaker.

NOTE: Improper grounding of connections

between loudspeakers and the rest of the audio
system may produce noise or hum, or cause serious
damage to the input and output stages of the system’s
electronic components.

Figure 4: 120 V AC, 3-Phase Wye System (Two Lines to Loudspeakers)

TIP: The 120 V AC, 3-phase Wye system with two

lines is recommended because it allows
loudspeakers to draw less current than with single-line
systems, thereby reducing voltage drop due to cable
resistance. It also excludes the potential of varying
ground to neutral voltages producing an audible hum.

Figure 5: 230 V AC, 3-Phase Wye System (Single Line to Loudspeakers)

CAUTION: For 230 V AC, 3-phase Wye

systems, never connect two lines to the AC
input of a UPQ-D Series loudspeaker, as the resulting
voltage would exceed the upper voltage limit
(275 V AC) and will damage the loudspeaker.

grounded outlet. To operate safely and effectively, it is
extremely important that the entire system be properly
grounded.

The AC Input connector also supplies power to any
additional loudspeakers connected to the loudspeaker’s
gray Loop Output connector.

CAUTION: When looping AC power for

loudspeakers, do not exceed the current
capability of the AC Input connector (20 A) or the
included AC power cable (15 A). Consider the total
current draw for all loudspeakers on the circuit,
including the first loudspeaker (Table 1).

AC Loop Output (Gray)

The gray AC Loop Output connector allows multiple
UPQ-D Series loudspeakers to be looped and powered from
a single power source. The 3-conductor powerCON 20 is
rated at 20 A and uses a locking connector that prevents
accidental disconnections. For applications that require
multiple UPQ-D Series loudspeakers, connect the AC Loop
Output of the first loudspeaker to the AC Input of the second
loudspeaker and so forth.

AC CONNECTORS

The UPQ-D Series loudspeaker user panel includes two
powerCON 20 connectors (Figure 6), one for AC Input (blue)
and one for AC Loop Output (gray).

Figure 6: AC Input (Left) and AC Loop Output (Right) Connectors

AC Input (Blue)

The blue AC Input connector supplies power to a
UPQ-D Series loudspeaker. The 3-conductor powerCON 20
is rated at 20 A and uses a locking connector that prevents
accidental disconnections. A 10-foot AC power cable, rated
at 15 A, is included with each loudspeaker. If the included
AC power cable is replaced, make sure to use a cable with
the appropriate power plug (on the other end) for the region
where the unit will be operated. The UPQ-D Series require a

The maximum number of loudspeakers that can be looped
from the AC Loop Output connector is determined by the
voltage of the power source, the current draw of the looped
loudspeakers, the circuit breaker rating, and the rating of the
AC power cable connected to the first UPQ-D Series
loudspeaker (Table 1).

WIRING AC POWER CABLES

UPQ-D Series loudspeakers ship with a gray powerCON 20
cable mount connector, rated at 20 A, for assembling AC
looping cables (Figure 7). The pins on the powerCON 20 cable
mount connector are labeled as follows:

• L (Line)

• N (Neutral)

• PE (Protective Earth or Ground)

Figure 7: powerCON20Cable Mount Connector

How AC power cables are wired is determined by the type of
AC power distribution system used (see “AC Power
Distribution” on page 13). When wiring AC power cables for
single-line systems, use one of the wiring schemes shown in
Figure 8 and described in Table 2:

VOLTAGE REQUIREMENTS

A UPQ-D Series loudspeaker operates as intended when
receiving AC voltage within the following range:

• 90–264 V AC, 50–60 Hz

If the voltage drops below 90 V, the loudspeaker uses stored
power to continue operating temporarily; the loudspeaker
powers off if the voltage does not return to its operating range.

If the voltage rises above 275 V, the power supply could
become damaged.

CAUTION: The power source for a UPQ-D Series

loudspeaker should always operate within the
required operating range, at least a few volts from the
upper and lower limits. This approach ensures that AC
voltage variations from the service entry—or peak
voltage drops due to cable runs—will not cause the
loudspeaker’s amplifier to cycle on and off or cause
damage to the power supply.

CURRENT REQUIREMENTS

Current draw for loudspeakers is dynamic and fluctuates as
operating levels change. Because different cables and circuit
breakers heat up at varying rates, it is important to understand
the following types of current ratings and how they affect
circuit breaker and cable specifications.

CAUTION: When wiring AC power cables and

distribution systems, it is important to preserve
AC line polarity and connect the earth ground at both
ends of the cable. A UPQ-D Series loudspeaker
requires a grounded connection. Always use a
grounded outlet and plug. It is extremely important that
the system be properly grounded to operate safely and
properly. Do not ground-lift the AC cable.

• Idle Current — The maximum rms current during idle

periods.

• Maximum Long-Term Continuous Current — The

maximum rms current during a period of at least
10 seconds. The maximum long-term continuous current is
used to calculate temperature increases for cables and to
ensure that the size and gauge of each cable conforms to
electrical code standards. This current rating is also used
to select appropriately rated, slow-reacting thermal
breakers, which are recommended for loudspeaker power
distribution. In addition, the maximum long-term
continuous current can be used to calculate the AC
looping capability for UPQ-D Series loudspeakers.

• Burst Current — The maximum rms current during a

period of around 1 second. The burst current is used as a
rating for magnetic breakers. It is also used for calculating
the peak voltage drop in long AC cable runs according to
the following formula:

V pk (drop) = I pk x R (cable total)

• Maximum Instantaneous Peak Current — A rating for

fast-reacting magnetic breakers.

CHAPTER 2: POWER REQUIREMENTS

!

Use the information in Appendix C, “UPQ-D Series
Specifications.” to select the appropriate cable gauge and
circuit breaker ratings for the system’s operating voltage.

The minimum electrical service amperage required by a
loudspeaker system is the sum of the maximum long-term
continuous current for all loudspeakers. An additional
30 percent above the combined Maximum Long-Term
Continuous amperages is recommended to prevent peak
voltage drops at the service entry.

NOTE: For best performance, the AC cable

voltage drop should not exceed 10 V
(10 percent at 115 V and 5 percent at 230 V). This
approach ensures that the AC voltage variations from
the service entry—or peak voltage drops due to longer
cable runs—do not cause the amplifier to cycle on and
off.

INTELLIGENT AC POWER SUPPLY

The UPQ-D Series Intelligent AC™ power supply
automatically selects the correct operating voltage (allowing
the loudspeaker to be used internationally without manually
setting voltage switches), eliminates high inrush currents
with soft-start power up, suppresses high-voltage transients
up to several kilovolts, filters common mode and differential
mode radio frequencies (EMI), and sustains operation
temporarily during low-voltage periods.

Powering on UPQ-D Series

When powering on a UPQ-D Series loudspeaker, the
following startup events take place over several seconds.

1. Audio output is muted.

2. Voltage is detected and the power supply mode is auto­matically adjusted as necessary.

3. The power supply ramps up.

4. On the user panel, the Active/Status LED flashes multiple
colors successively.

5. The Active/Status LED turns solid green, indicating the
loudspeaker is unmuted and ready to output audio.

CAUTION: If the Active/Status LED does not

turn solid green, or the UPQ-D Series
loudspeaker does not output audio after 10 seconds,
remove AC power immediately and verify that the
voltage is within the required range. If the problem
persists, contact Meyer Sound Technical Support.

ELECTRICAL SAFETY GUIDELINES

Earth ground

Chassis ground

Make sure to observe the following important electrical and
safety guidelines.

• The powerCON 20 connector should not be engaged or

disengaged when under load or energized. Either
de-energize or disconnect the other end of the cable.

• UPQ-D Series loudspeakers require grounded outlets.

Always use a grounded outlet and plug.

UPQ-D SERIES OPERATING INSTRUCTIONS

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

ground pin.

• Do not exceed the current capability of the 20 A AC Input

connector for the loudspeaker. When looping
loudspeakers, consider the total current draw for all
loudspeakers on the circuit, including the first loudspeaker.

• Make sure the AC power cable for the loudspeaker has the

appropriate power plug (on the other end) for the area in
which the loudspeaker will be operated. In addition, the AC
power cable must be rated for the total current draw of all
loudspeakers looped from the power source.

• Do not operate the unit if the power cable is frayed or

broken.

• Keep all liquids away from UPQ-D Series loudspeakers to

avoid hazards from electrical shock.

CHAPTER 3: AMPLIFICATION AND AUDIO CONNECTORS

The UPQ-D Series drivers are powered by a proprietary
2-channel, open-loop, class D amplifier. The audio signal is
processed with electronic crossover, correction filters for flat
phase and frequency responses, and by driver protection
circuitry. Each channel has peak and rms limiters that prevent
driver over-excursion and regulate voice coil temperatures.

The UPQ-D Series user panel (Figure 9) includes Input and Loop
output connectors for audio, Limit and Active LEDs, and RMS
connectors and controls (see Chapter 6, “RMS Remote
Monitoring System”).

AUDIO CONNECTORS

The UPQ-D Series loudspeakers are available with XLR 3-pin
(Figure 10) or 5-pin connectors (Figure 11) for audio Input and
audio Loop output. XLR 5-pin connectors accommodate both
balanced audio and RMS signals.

Figure 10: XLR 3-Pin Audio Connectors, Input and Loop Output

Figure 9: UPQ-D Series User Panel (3-pin XLR and optional RMS)

Figure 11: XLR 5-Pin Audio Connectors, Input and Loop Output

Audio Input (XLR 3-Pin or 5-Pin Female)

The XLR 3-pin or 5-pin female Input connector accepts
balanced audio signals with an input impedance of 10 k
connector uses the following wiring scheme:

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

• Pin 2 — Signal (+)

• Pin 3 — Signal (–)

• Pin 4 — RMS (polarity insensitive)

• Pin 5 — RMS (polarity insensitive)

• Case — Earth (AC) ground and chassis

NOTE: Pins 4 and 5 (RMS) are included only with

XLR 5-pin connectors.

Ω. The

19

CHAPTER 3: AMPLIFICATION AND AUDIO CONNECTORS

!

Pins 2 and 3 carry the input as a differential signal. Pin 1 is
connected to earth through a 1 kΩ, 1000 pF, 15 V clamped
network. This circuitry provides virtual ground lift for audio
frequencies while allowing unwanted signals to bleed to
ground. Make sure to use balanced XLR audio cables with
pins 1–3 connected on both ends. Telescopic grounding is
not recommended and shorting an input connector pin to the
case may cause a ground loop, resulting in hum.

TIP: If the loudspeaker produces unwanted noise

or hiss, disconnect its input cable. If the noise
stops, there is most likely nothing wrong with the
loudspeaker. To locate the source of the noise, check
the source audio, AC power, and electrical ground.

Audio Loop Output (XLR 3-Pin or 5-Pin Male)

The XLR 3-pin or 5-pin male Loop output connector allows
multiple loudspeakers to be looped from a single audio
source. The Loop output connector uses the same wiring
scheme as the Input connector (see “Audio Input (XLR 3-Pin
or 5-Pin Female)” on page 19). For applications that require
multiple UPQ-D Series loudspeakers, connect the Loop
output of the first loudspeaker to the Input of the second
loudspeaker and so forth.

NOTE: The Loop output connector is wired in

parallel to the Input connector and transmits
the unbuffered source signal even when the
loudspeaker is powered off.

Calculating Load Impedance for Looped Audio Signals

To a v oid d i st o rt i on w h en lo o pin g m ul ti pl e l ou d spe ak e rs ,
make sure the source device can drive the total load
impedance of the looped loudspeakers. In addition, the
source device must be capable of delivering approximately
20 dBV (10 V rms into 600
the operating bandwidth of the loudspeakers.

Ω) to yield the maximum SPL over

NOTE: Most source devices are capable of

driving loads no less than 10 times their output

impedance.

TIP: Audio outputs from Meyer Sound’s Galileo

GALAXY Network Platform have an output
impedance of 50 ohms. Each output can drive up to 20
Meyer Sound (10 k

CAUTION: Make sure that all cables for looped

loudspeakers are wired correctly (Pin 1 to
Pin 1, Pin 2 to Pin 2, and so forth) to prevent the
polarity from being reversed. If one or more
loudspeakers in a system have reversed polarity,
frequency response and coverage will be significantly
degraded.

Ω) loudspeakers without distortion.

TRUPOWER LIMITING

The UPQ-D Series loudspeakers employ Meyer Sound’s

®

advanced TruPower
constant driver impedance and set the limiting threshold by
measuring voltage alone. This method is inaccurate, because
driver impedances change as frequency content in the source
material changes, and as thermal values for the loudspeaker’s
voice coil and magnet vary. Consequently, conventional
limiters often begin limiting prematurely, which reduces
system headroom and dynamic range.

In contrast, TruPower limiting anticipates varying driver
impedances by measuring both current and voltage to
compute the actual power dissipation in the voice coil. This
approach improves performance, both before and during
limiting, by allowing the driver to produce the maximum SPL
across its entire frequency range while also retaining signal
peaks. TruPower limiting also eliminates power compression
at high levels over lengthy periods, which helps regulate voice
coil temperatures, thereby extending the life of the driver.

HF and LF Limit LEDs

The low- and high-frequency drivers for UPQ-D Series
loudspeakers are powered by separate amplifier channels, each
with their own limiter. Limiting activity is indicated with two Limit
LEDs on the user panel. The top Limit LED (Figure 12) indicates
limiting for the high-frequency channel and the bottom Limit
LED indicates limiting for the low-frequency channel.

Figure 12: UPQ-D1/2/3 Limit LEDs

When engaged, the limiters not only protect the drivers but also
prevent signal peaks from causing excessive distortion in the
amplifier channels, thereby preserving headroom and
maintaining smooth frequency response at high levels. When
levels return to normal, below the limiter thresholds, limiting
ceases.

A UPQ-D Series loudspeaker performs within its acoustical
specifications at normal temperatures when the Limit LEDs are
unlit, or when the LEDs are lit for 2 seconds or less and then turn
off for at least 1 second. If the LEDs remain lit for longer than
3 seconds, the loudspeaker enters hard limiting where:

• Increases to the input level have no effect

• Distortion increases due to clipping

If a loudspeaker is overheating (for RMS-equipped
loudspeakers, one can verify this situation in Compass RMS), a
reduction in SPL may be necessary. If after a reduction in SPL
and an appropriate cooling period the Active/Status LED
continues to flash red (does not return to solid green), contact
Meyer Sound Technical Support.

If the Active/Status LED flashes red and the loudspeaker does
not output audio, contact Meyer Sound Technical Support
immediately.

CAUTION: If a UPQ-D Series loudspeaker

system consistently overheats before reaching
the desired SPL, consider adding more units to the
system.

NOTE: During startup, the On/Status LED flashes

multiple colors successively. For more
information about the power on sequence, see
“Intelligent AC Power Supply” on page 16.

TIP: When a UPQ-D Series loudspeaker is

connected to an RMS network, the Compass RMS
software provides additional feedback about the
loudspeaker’s hardware status and operating
temperature. For more information, see Chapter 6, “RMS
Remote Monitoring System.”

AMPLIFIER COOLING SYSTEM

The UPQ-D Series loudspeaker is convection cooled. The
amplifier’s heat sink provides natural convection cooling from
the air flowing near its fins.

• Drivers are subjected to excessive heat and excursion,

thereby compromising their lifespan

CAUTION: The Limit LEDs indicate when a safe,

optimum level is exceeded. If a UPQ-D Series
loudspeaker system begins to limit before reaching the
desired SPL, consider adding more units to the system.

CAUTION:

ON/STATUS LED

During normal operation, when a UPQ-D Series loudspeaker is
powered on, the On/Status LED is solid green. If the
loudspeaker encounters a hardware fault, or the unit begins to
overheat, the LED flashes red. In some instances, the
loudspeaker will continue to output audio while the LED flashes
red, though with a reduction in the limiter threshold and acoustic
output to protect the loudspeaker.

CAUTION: To ke e p a UPQ -D Se ri es l ou dsp ea ke r

from overheating, allow at least 3 inches behind

the loudspeaker for proper ventilation.

TIP: The UPQ-D Series loudspeaker heat sink can

reach temperatures up to 80° C (176° F) during
extreme operation. Wait 15 minutes for the unit to cool
before touching.

CHAPTER 4: ADDING LOW FREQUENCY CONTROL

!

A UPQ-D Series loudspeaker system can be deployed with
Meyer Sound self-powered low frequency control elements
(see Table 3). These subwoofers achieve very low frequency
responses and extend the system response appreciably,
increasing the overall acoustic power of the system in the
lowest frequencies.

The ideal ratio of UPQ-D Series loudspeakers to low
frequency control element depends on the following
variables:

• Subwoofer model

• System configuration

• Frequency content of the source material

• Headroom required for low frequencies

For most applications, the ratios in Table 3 should yield
good results.

Ta bl e 3: Re c o mm e nd e d Meyer Sound Subwoofer

Subwoofer Frequency

Response

USW-210P 32–123 Hz ±4 dB 1:1 for most applications

750-LFC 37–110 Hz ±4 dB 1:1 for most applications

900-LFC 32–115 Hz ±4 dB 2:1 for most applications

1100-LFC 30–85 Hz ±4 dB 4:1 for most applications

Recommended Ratio
(Number of UPQ-D Series per
Subwoofer)

1:2 for applications requiring
more low end

1:1 for applications requiring

ADDING SUBWOOFERS BY DAISY-CHAINING

Full-range signals can be connected directly to
Meyer Sound self-powered loudspeakers, because the
loudspeakers have built-in active crossovers. Subwoofers
can be added to a UPQ-D Series system by simply
daisy-chaining them to the UPQ-D Series loudspeakers.

When UPQ-D Series loudspeakers are coplanar, or they are
very close together (about four to six feet like in the case of
pole mounting), the phase response will work well in the
area of interaction and the result will be a fairly flat
frequency response. However, the response will show an
increase in the 60–200 Hz range where the response of the
loudspeakers overlaps.

NOTE: If the subwoofer’s Limit LEDs begin to

light before reaching the required SPL, con­sider adding more subwoofers to meet the SPL
requirements without exposing the drivers to exces­sive heat and excursion.

USING A PROCESSOR

In larger systems when individual control for the
UPQ-D Series loudspeakers and subwoofers are needed or
desired, if the UPQ-D Series loudspeakers and subwoofer
are more than six feet apart, or if a delay is required between
them, use a measurement system like Meyer Sound’s SIM
to determine appropriate delay and polarity settings.

CAUTION: Make sure the source signal is

sufficient to drive the total load impedance of
the daisy-chained loudspeakers (see “Calculating
Load Impedance for Looped Audio Signals” on
page 20).

TIP: MAPP can be used to accurately predict

the appropriate loudspeaker deployment and
subwoofer integration for loudspeaker systems,
complete with coverage data, system delay and
equalization settings, rigging information, and
detailed design illustrations. For more information,
see “MAPP System Design Tool” on page 33.

1. Connect the source signal to the Input of the first
UPQ-D Series loudspeaker, then connect the Loop
output of the first loudspeaker to the Input of the second
loudspeaker and so forth.

2. Connect the Loop output of the last UPQ-D Series
loudspeaker in the chain to the subwoofer Input.

CHAPTER 5: QUICKFLY RIGGING

The UPQ-D Series loudspeakers are compatible with

®

Meyer Sound’s QuickFly

system, a comprehensive
collection of custom-designed rigging, flying, and mounting
options. Comprising rugged, reliable, and easy-to-configure
components, QuickFly supports deployment of UPQ-D
Series loudspeakers as either individual loudspeakers or as
arrays at precise angles to take full advantage of their
directional components. The top and bottom plates for the
UPQ-D Series cabinet are constructed of heavy-duty,
high-strength, corrosion-resistant 6061-T6 aluminum and
include threaded metric holes (for M10 screws) for easy
connection to QuickFly rigging and third-party mounting
options.

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 method for their application.
Rigging should only be carried out by experienced
professionals.

BASIC EYE BOLT RIGGING

The UPQ-D Series loudspeaker ships with two M10 threaded,
25 mm eye bolts that attach to the top or bottom of the
loudspeakers and can be used to suspend them. A minimum
of two eye bolts is required when suspending a single
loudspeaker. The use of two eye bolts provides the added
flexibility of aiming and tilting the loudspeaker for targeted
coverage.

Figure 13: UPQ-D Series Top Plate with Threaded Holes for Eye Bolts

• 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 and eye bolts are tightened securely.

Meyer Sound recommends using Loctite

®

on eye bolt

threads and safety cables.

• Inspect mounting and rigging hardware regularly.

Immediately replace any worn or damaged components.

Figure 14: UPQ-D Series Loudspeaker with Two Eye Bolts

NOTE: Up to two UPQ-D Series loudspeakers,

oriented vertically, can be suspended with
Meyer Sound eye bolts at a 5:1 safety factor. For this
configuration, the top loudspeaker would have two
eye bolts installed on its top plate and two eye bolts
installed on its bottom plate for connecting to the
second loudspeaker. Additional M10 eye bolts
(PN 40.185.013.01 for a set of 2) are available from
Meyer Sound.

THE MPA-UPQ ARRAY ADAPTER

The MPA-UPQ array adapter provides a solid connection
between UPQ-D Series loudspeakers to form horizontal and
vertical arrays of up to three loudspeakers. The six M10 screw
holes at the front of the adapter plate are used to adjust the
distance between the loudspeakers to achieve the desired
splay angle (from 34° to 50°) and coverage. The adapter plate
has three rows of shackle holes that offer the flexibility of flying
horizontal and vertical arrays, as well as single loudspeakers.

Suspending Single Loudspeakers Vertically with the MPA-UPQ

A single MPA-UPQ array adapter plate can be used to
suspend a single UPQ-D Series loudspeaker vertically. The
adapter plate attaches to the top center of the loudspeaker
with the included M10 knobs. Shackles attach to the adapter
plate’s middle shackle holes (oriented up).

Figure 17: MPA-UPQ Array Adapter Plate

The MPA-UPQ array adapter kit (PN 40.185.054.01) includes
two plates and eight M10 knobs and washers. A single kit can
create an array of two UPQ-D Series loudspeakers; two kits
are required for an array of three loudspeakers.

Arrays are assembled by attaching the array adapter plates to
the top and bottom plates of the UPQ-D Series loudspeakers
and securing them with the included M10 knobs and washers.

CAUTION: The MPA-UPQ array adapter

supports a maximum of three UPQ-D Series

loudspeakers in an array.

NOTE: Optimal acoustical performance for a

UPQ-D Series array is achieved by using the
adequate number of units as well as selecting the
specific angles between cabinets to fill the
requirements of the application. In general, larger
angles can create a hole in the coverage and smaller
angles can create too much interaction.

CHAPTER 6: RMS REMOTE MONITORING SYSTEM

The UPQ-D Series loudspeakers optionally include an RMS
remote monitoring system module, allowing them to be
connected to an RMS network. RMS reports, in real time, the
status and power usage of multiple Meyer Sound
loudspeakers from a Mac
The RMServer

™

communicates with Meyer Sound

®

or Windows®-based computer.

loudspeakers equipped with RMS modules. RMServer is a
compact, Ethernet-based hardware unit with two FT-10 RMS
data ports. RMServer stores system configurations internally,
eliminating most manual data entry. Systems can be
monitored from a computer at front-of-house or backstage, or
from a laptop anywhere within the venue over WiFi.

NOTE: For the latest RMS system requirements,

visit the Meyer Sound website

(http://www.meyersound.com

).

NOTE: RMS does not control AC power.

COMPASS CONTROL SOFTWARE

Compass Control Software provides extensive system status
and performance data for each loudspeaker via the RMServer
tab including amplifier voltage, limiting activity, power output
and driver status, as well as mute and solo capability.
Loudspeakers are added to the RMS network and assigned a
node name during a one-time discovery procedure. After
loudspeakers are identified on the RMS network, they appear
in Compass RMS as icons that can be customized to suit the
needs of the application (Figure 27).

Individual loudspeakers can be physically identified with the
Wink option in RMS which lights the Wink LED on the RMS
module of that particular loudspeaker. Conversely, a
loudspeaker can be identified in Compass by pressing the
Identify button on the loudspeaker’s RMS module.

Loudspeaker icons can be arranged in Compass RMS and
saved as pages to represent how the loudspeakers have been
deployed in the system. Multiple pages can be saved and
recalled for specific performances and venues.

RMS MODULE

The UPQ-D Series RMS user panel (Figure 28) includes an
Identify button, Remote Mute switch, Wink/Activity LED, and
two Network connectors.

Figure 28: UPQ-D Series RMS Module

NOTE: The Identify button and Wink/Activity LED

on the RMS user panel are used exclusively by
RMS and have no effect on the acoustical or electrical
activity of the loudspeaker.

Figure 27: Compass RMS Window

Identify Button

The Identify button serves the following functions:

• If the loudspeaker has not yet been discovered on the RMS

network (Wink/Activity LED not lit), press the Identify
button to discover it.

• To r e mo v e t he lo u dsp ea k er fr o m t he RM S n e two rk , pr es s

and hold the Identify button during startup (see “Resetting
the RMS Module” on page 32).

• To wink a discovered loudspeaker, press the Identify

button. The Wink LED on the loudspeaker icon in Compass
RMS lights up and the Wink/Activity LED on the
loudspeaker’s RMS user panel turns solid green. Press the
Identify button again to unwink the loudspeaker.

31

CHAPTER 6: RMS REMOTE MONITORING SYSTEM

TIP: The loudspeaker can also be winked by

clicking the Wink button on the loudspeaker

icon in Compass RMS.

Wink/Activity LED (Green)

The green Wink/Activity LED indicates the status of the
loudspeaker:

• During startup, the LED flashes green 10 times.

• If the loudspeaker has not yet been discovered on the

RMS network, the LED is not lit after startup.

• If the loudspeaker has been successfully discovered on

the RMS network, the LED flashes green continuously
and flashes more rapidly with increased data activity.

• When the loudspeaker is winked, either by clicking the

Wink button in Compass RMS or by pressing the Identify
button on the RMS user panel, the LED is solid green.
The LED remains solid green until the loudspeaker is
unwinked.

TIP: The Wink function is useful for identifying

the physical loudspeaker corresponding to a

loudspeaker icon in Compass RMS.

Remote Mute Switch

The recessed Remote Mute switch on the UPQ-D Series
RMS module (Figure 29) determines whether Compass RMS
can control muting and soloing of the loudspeaker. The
UPQ-D Series ships from the factory with the switch
enabled.

RMS Network Connectors

The Weidmuller 2-conductor, locking connectors transfer
data to and from the RMS network. Two connectors are
provided to allow for easy connection of multiple
(daisy-chained) loudspeakers on the network. Included with
each RMS-equipped loudspeaker are RMS cable
connectors and mounting blocks for constructing RMS
cables. The mounting blocks allow the Weidmuller
connectors to be securely attached to the RMS module with
screws.

NEURON ID FOR RMS MODULE

Each RMS module has a unique 12-character Neuron ID
(NID) that identifies the loudspeaker on the network. The
NID is automatically detected by RMServer but can also be
entered manually, if necessary, when configuring RMS
systems in Compass RMS without loudspeakers present.
The NID label is located on the RMS user panel near the
orange Network connectors.

RESETTING THE RMS MODULE

The Identify button can be used to reset the UPQ-D Series
RMS module when powering on the loudspeaker. This
action will cause the module to be removed from the RMS
network.

To r e se t t h e R MS m o du l e:

1. Power down the loudspeaker.

2. Press and hold the Identify button.

3. While continuing to hold down the Identify button, power
on the loudspeaker.

Figure 29: Remote Mute Switch

• Disable: When the Remote Mute switch is set to Disable

(to the left), the loudspeaker cannot be muted or soloed
from Compass RMS.

• Enable: When the Remote Mute switch is set to Enable

(to the right), the loudspeaker can be muted and soloed
from Compass RMS.

NOTE: Compass RMS has a preference that

can be set to disable Mute and Solo functions,
eliminating any possibility of accidentally muting
loudspeakers.

4. After the Wink/Status LED flashes on and off, release the
Identify button. The RMS module is reset and the
loudspeaker is removed from the RMS network.

CHAPTER 7: SYSTEM DESIGN AND INTEGRATION TOOLS

This chapter introduces MAPP, Meyer Sound’s patented
system design tool, the Galileo GALAXY Network Platform,
and SIM, a comprehensive system for measurement and
analysis.

MAPP SYSTEM DESIGN TOOL

The MAPP System Design Tool (Figure 30) is a powerful,
cross-platform application for accurately predicting the
coverage pattern, frequency response, phase response,
impulse response, and SPL capability of single or arrayed
Meyer Sound loudspeakers.

Figure 30: MAPP System Design Tool

MAPP client software allows for configuration of
Meyer Sound loudspeaker systems and definition of the
environment in which they operate, including air temperature,
pressure, humidity, and even the location and composition of
surfaces. Importation of CAD (.DXF) files containing detailed
venue information to act as a visual aid is also possible.

MAPP prediction requests are sent by the client software to
Meyer Sound servers, where complex, high-resolution
(magnitude and phase) polar data is processed with
sophisticated acoustical prediction algorithms. The resulting
predictions are then displayed in the MAPP client software.

TIP: Meyer Sound offers seminars and webinars

on using MAPP. For more information, visit

MAPP Capabilities

With MAPP, a user can:

•Simulate different loudspeaker configurations to refine
system designs and determine the best coverage for
intended audience areas

•Model loudspeaker interactions to locate constructive
and destructive interferences, so that loudspeakers can
be re-aimed and repositioned as necessary

Whether planning for fixed installations or for tours with
multiple venues, use MAPP to accurately predict the
appropriate loudspeaker deployment for each job, complete
with coverage data, system delay and equalization settings,
rigging information, and detailed design illustrations. MAPP’s
accurate, high-resolution predictions ensure that systems
will perform as expected, thereby eliminating unexpected
coverage problems and minimizing onsite adjustments.

The key to the accuracy of MAPP’s predictions is
Meyer Sound’s exhaustive database of loudspeaker
measurements. Performance predictions for each
loudspeaker are based on 720 1/48th-octave-band
measurements taken with a SIM audio analyzer (see “SIM
Measurement System” on page 34) in the Meyer Sound
anechoic chamber. The extraordinary consistency between
Meyer Sound loudspeakers guarantees that predictions from
MAPP will closely match their actual performance.

•Place microphones anywhere in the sound field and
predict loudspeaker frequency response, phase

CHAPTER 7: SYSTEM DESIGN AND INTEGRATION TOOLS

GALILEO GALAXY NETWORK PLATFORM

The Galileo GALAXY Network Platform is a sophisticated
loudspeaker management tool for controlling all
Meyer Sound speaker types. The GALAXY loudspeaker
processor extends a high level of audio control in driving
and aligning loudspeaker systems with multiple zones. It
provides a powerful tool set for corrective equalization (EQ)
and creative fine-tuning for a full range of applications from
touring to cinema.

Users can readily program the GALAXY processor using
Compass software running on a host computer or via the
Compass Go application for the iPad. Compass Control
Software includes custom-designed settings for each family
of speakers, as well as to integrate families together. For
example, the Product Integration feature matches the phase
characteristics between Meyer speaker families to ensure
the most coherent summation.

Processing tools for inputs and outputs include delay,
parametric EQ and U-Shaping EQ. Output processing also
includes polarity reversal, Low-Mid Beam control (LMBC),
atmospheric correction, and All Pass filters.

The built-in summing and delay matrices allow a user to
easily assign gain and delay values, respectively, at each
cross point. This capability greatly facilitates using one
loudspeaker to satisfy multiple purposes.

Front panel controls let a user intuitively and quickly operate
a GALAXY processor without a computer during live use.

The rear panel includes SIM bus port(s) for direct connection
to Meyer Sound’s SIM audio analyzer, allowing the GALAXY
processor to function as a line switcher for the analyzer.
With this capability, a user can take measurements from any
selection of GALAXY inputs and outputs without patching
beyond a single connection to the analyzer.

The GALAXY 408, GALAXY 816 and GALAXY 816-AES3
processor versions have the same audio processing
capability with different I/O. See www.meyersound.com to
locate their datasheets for more information.

allows application of precise corrections to balance system
response using frequency and phase domain information.

Source Independent Measurement Technique

The SIM audio analyzer implements Meyer Sound’s source
independent measurement technique. This dual-channel
method makes analysis of statistically unpredictable
excitation signals possible. Any excitation signal, within the
desired frequency range, can be used to obtain highly
accurate measurements for acoustical or electronic systems.

For example, during a performance, both the input signal and
the measured output of the loudspeaker system can be
analyzed by SIM and the results can be used to:

•View measurement data as amplitude versus time
(impulse response) or amplitude and phase versus
frequency (frequency response)

•View single-channel frequency domain data with a
logarithmic frequency axis

•Determine and internally compensate for propagation
delays using the SIM Delay Finder

SIM Applications

SIM’s main applications are testing and aligning loudspeaker
systems, which entails:

•Measuring propagation delays between subsystems to
determine appropriate delay times

•Verifying correct polarity

•Measuring and comparing phase responses of
subsystems

•Measuring variations in frequency response caused by the
acoustical environment and the placement and interaction
of loudspeakers to determine corrective equalization

•Optimizing subwoofer integrations

SIM MEASUREMENT SYSTEM

The SIM audio analyzer is a high-resolution audio
measurement system comprising software, hardware,
microphones, and accessory cables. SIM presents measured
audio frequencies at a resolution of 48 points per octave,
where the 48 points per octave are arranged in even
frequency increments in each octave group, equal to the total
frequencies in that octave divided by 48. This resolution

SIM can also be used in the following applications:

•Microphone calibration and equalization

•Transducer evaluation and correction

•Echo detection and analysis

•Vibration analysis

•Architectural acoustics

APPENDIX A: MEYER SOUND WEATHER PROTECTION

!

UPQ-D SERIES OPERATING INSTRUCTIONS

The Weather Protection option from Meyer Sound is
intended to increase the useful life of Meyer Sound
loudspeakers when they are installed outdoors and exposed
to different and often harsh weather conditions.
Meyer Sound Weather Protection includes a penetrating
treatment to raw wood, use of special primers, and plating
on all steel parts used (or alternatively, the use of stainless
steel hardware). Weather Protection is designed to prevent
malfunctions caused by harsh operating environments and
slows the accelerated wear and tear that occurs in outdoor
environments.

When Is Weather Protection Advisable?

Weather Protection is strongly recommended for all
permanent outdoor installations where loudspeakers are
directly exposed to the elements. This recommendation
includes desert and semi-arid climates, where protection
against dust and sand is important, and where infrequent
rainstorms can contribute to deterioration of loudspeaker
components.

Weather Protection is also recommended when the
loudspeakers are sheltered from direct exposure to
precipitation, but are nevertheless exposed to prolonged
high humidity, fog or mist. Examples would be installations
on covered outdoor terraces or pavilions.

Weather Protection is further advisable for portable or
touring systems when any significant outdoor use is
anticipated. Even though standard procedures may call for
using external protective measures, these are often not
implemented in time to prevent moisture intrusions that
could lead to premature performance degradation of the
loudspeaker.

Climate Variation and Owner Maintenance

The wear and tear on a loudspeaker will vary significantly
with different climatic conditions. For example, a
weather-protected loudspeaker installed in a
sunlight-exposed location on an ocean pier will experience
much harsher conditions than a loudspeaker in a similar
installation that is shaded by trees and exposed only to
rainfall. The constant exposure to direct UV radiation and a
salt air environment will cause a loudspeaker to wear more
quickly than one with partial UV shielding and exposed only
to freshwater moisture.

air environments, the exterior grille can quickly show signs
of oxidation, causing unsightly discoloration.

Apart from selecting suitable weather protection, the
progress of wear and tear on the loudspeaker can be
slowed by a regular schedule of inspection and cleaning.
This maintenance is particularly necessary in harsh
environments. Inspection and cleaning should include
routine removal of any visible oxidation or environmental
particulates, as these can accelerate metal corrosion or
decay of the cabinet. If installed loudspeakers are not in use
for an extended period, exterior protection or temporary
removal and storage of the loudspeakers should be
considered.

Benefits of Weather Protection

There are several benefits to selecting the Meyer Sound
Weather Protection option:

Functionality—Weather Protection prolongs the service life
of the loudspeaker by preventing premature degradation of
internal components.

Safety—Weather Protection lessens the chance of electrical
malfunctions or structural failures.

WARNING: IT IS THE RESPONSIBILITY OF

PURCHASERS/USERS/OPERATORS TO
SELECT WEATHER PROTECTION WHEN
APPROPRIATE FOR THEIR USE AND TO
PERIODICALLY INSPECT THEIR LOUDSPEAKER
INSTALLATIONS FOR ANY DETERIORATION THAT
MAY LEAD TO SAFETY CONCERNS.

Aesthetics—Weather Protection slows wear and tear on the
exterior of the loudspeaker in harsh conditions. Early signs
of wear and tear on the exterior of the loudspeaker indicate
over-exposure to the elements.

Standards Compliance—Weather Protection helps in
meeting IP ratings for loudspeakers. IP ratings are an
internationally recognized standard often used in
installations involving our products. A further explanation of
IP ratings is given in the “IP Ratings” Section on page 37.

Wear can eventually affect the performance of the
loudspeaker. It also affects aesthetics. For example, in salt

35

APPENDIX A: MEYER SOUND WEATHER PROTECTION

WEATHER PROTECTION COMPONENTS

Standard Weather Protection

Meyer Sound designs toward an IP rating of IPX4 (see “IP
Ratings” on page 37) for Standard Weather Protection,
which includes the following components:

•Wood treatment—Prior to cabinet manufacturing, the
raw wood receives a special treatment that penetrates
and stabilizes the wood fibers to withstand a wide range
of temperatures and exposure to extreme humidity.

•Cabinet finishing—The assembled cabinets receive a
highly impervious finish that includes a sealing primer
and a finishing topcoat. The coatings are applied on both
surfaces, with one coat on the interior and two on the
exterior. The final step is a two-part modified acrylic
urethane similar to that used in military applications.

•Driver treatment—All cone drivers are coated with a
water-resistant sealant.

•Exterior protection—Grille frames are coated to resist
corrosion, and all components that mount to the cabinet
use custom gaskets and stainless steel fasteners.

If in doubt about an installation method, contact Meyer
Sound Technical Support for assistance.

Always discuss the environmental conditions of your Meyer
Sound installation with your Sales Manager, and verify the
availability of Weather Protection for your selected
loudspeaker models. The Sales Manager, together with
Te ch n ic a l Su p po r t, wi l l v er i fy th e a pp ro pr i at e l ev e l o f
weather protection for the loudspeakers and related rigging
hardware.

•Removable rain hood—The rain hood is designed to
shield connectors even in wind-driven rain.

INSTALLATION PRACTICES

Meyer Sound assumes normal and accepted installation
practices are used when installing Meyer Sound
Loudspeakers outdoors. Deviation from such practices may
cause weather protection to be ineffective and void the
warranty for the loudspeaker.

Examples of unacceptable and acceptable installation
practices include:

•Loudspeakers installed outdoors should not face
upward.

•Loudspeakers with a rain hood should be installed in
such a way that the rain hood opening is not facing any
direction but down.

•Meyer Sound-supplied rigging components should not
be modified (for example, by drilling additional holes in a
MUB for mounting to a wall). When an installer/integrator
modifies a Meyer Sound supplied rigging component to
support their installation method, it is considered
compromised and out of warranty.

•All loudspeaker cabling must be installed with a
“drip-loop” or equivalent method to ensure that rain or
water is NOT wicked toward the loudspeaker.

UPQ-D SERIES OPERATING INSTRUCTIONS

IP RATINGS

IP stands for “Ingress Protection.” The current format for expressing an IP rating is a 2-digit code. The first digit of an IP
rating represents protection from solid objects. The second digit of an IP rating represents protection from water or
moisture. Table 5 provides a chart of IP ratings and the corresponding definitions of the rating.

NOTE: IP ratings only apply to the “ENCLOSURE.” A loudspeaker is considered an enclosure and as such an

IP rating can be applied to it. Rigging hardware is not an enclosure and therefore IP ratings do not apply. Also,
cable and cable-mount connectors used to connect to the loudspeaker are NOT part of the enclosure and therefore
not part of the IP rating. Only the chassis-mounted part of the connector is considered part of the enclosure.

Weather-protected UPQ-D Series loudspeakers include a rain hood for indoor/outdoor touring and sheltered outdoor
installations. Meyer Sound offers two rain hood models: A fixed rigid rain hood for permanent installations and a foldable hood
for portable applications. Please specify the desired rain hood when placing an order.

RIGID RAIN HOOD

The UPQ-D Series rigid removable rain hood is easily attached and removed with the included four screws (Figure 31).

Figure 31: UPQ-D Series with rigid rain hood in Vertical Orientation (left), Horizontal Orientation (top right) and Interior Cable Routing (bottom right))

To a t ta c h t he U P Q- D S e ri e s ri g id ra i n h oo d :

1. Attach any required cables to the UPQ-D Series loudspeaker.

2. Carefully route the cables, so that they wrap over and down the inner rainhood wall.

3. Attach the rain hood to the user panel, and secure it to the center of the panel with its four 6-32 screws.

4. Make sure to tighten the screws to create a good seal against the user panel. The recommended torque value for the screws
is 10–12 in-lb (1.1–1.4 N·m).

CAUTION: There is only one proper vertical loudspeaker orientation and one proper horizontal loudspeaker orien-

tation once the rainhood is installed. See Figure 31.

CAUTION: The weather-protected UPQ-D Series loudspeaker must be mounted with a 0

slight down-tilt. This angle shields the driver from the elements and does not allow water to accumulate. Do not tilt

the cabinet up, as the drivers and cabinet will accumulate water.

NOTE: Weather-protected units using the rigid rainhood are rated IPX4 for water intrusion.

FOLDABLE RAIN HOOD

The UPQ-D Series foldable rain hood is installed on the unit when shipped. Four screws secure its frame permanently into place
(Figure 32).When using the rainhood, the loudspeaker has only one possible vertical and one possible horizontal position, as all
cables must exit from the lower end of the loudspeaker.

Figure 32: UPQ-D Series with foldable rain hood in vertical (left) and horizontal (right) orientations

To u s e t he UP Q- D S e ri e s f ol d ab l e r ain h o od :

1. Detach the Velcro straps and extend the rain hood.

2. Lift the front flap.

3. Attach any required cables to the UPQ-D Series loudspeaker.
