Meyer Sound’s UPQ‑D3 wide coverage loudspeaker evolves from the
UPQ‑1P and UPQ‑2P product line, now optimized using the advanced
amplifier and processing technology that made the LEO® family an award‑
wining product line. UPQ‑D3 features:
• Wider vertical coverage, Constant‑Q horn with ‑6 dB points at 80°
horizontal x 80° vertical (‑10 dB points at 100° horizontal x 100°
vertical)
• An innovative, newly designed, 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
• Redesigned cabinet that retains the original size, grille frame, and
rigging options of previous UPQ products
The UPQ‑D3 offers an extremely consistent polar response and a gentle
coverage rolloff that extends uniformly out to its ‑10 dB points of 100°
by 100°. The horn’s smooth and consistent performance is the result of
meticulous research in Meyer Sound’s anechoic chamber, and it exhibits a
remarkably consistent beamwidth in both the horizontal and vertical planes.
The UPQ‑D3 horn also delivers uniform attenuation for all frequencies
outside the specified beamwidth.
In addition to the Constant‑Q horn, the loudspeaker features a low
frequency 15‑inch neodymium magnet cone driver and 4‑inch diaphragm
compression driver, both designed and manufactured at Meyer Sound’s
Berkeley, California headquarters. Suitable for use in a range of sound
reinforcement applications, the UPQ‑D3 works well as a front‑of‑house
main loudspeaker in small to mid‑sized venues, or as a fill loudspeaker in
larger systems.
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‑D3’s 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‑D3 uses a XLR 3‑pin female
input with male loop output connector.
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.
The UPQ‑D3 provides extremely high power output with low distortion in
a vented two‑way enclosure. The UPQ‑D3’s durable trapezoidal enclosure
has a slightly textured black finish, an integral stand mount receptacle,
and versatile rigging end plates. Made of heavy‑duty, high‑strength,
corrosion‑resistant 6061‑T6 aluminum, the endplates incorporate threaded
M10 attachment points.

QuickFly
rigging options include the MPA‑UPQ pick‑up and array plate
and MYA‑UPQ mounting yoke. Other options include Meyer Sound weather
protection and custom color finishes for specific cosmetic requirements.

ACCESSORIES AND ASSOCIATED PRODUCTS
MPA-UPQ Pick Up and Array Plate: The MPA‑UPQ Pick Up and Array Plate kit allows for one or multiple UPQ loudspeakers to be suspended at a
vertical angle. The kit includes two plates to facilitate installation of two UPQ‑D loudspeakers in both horizontal and vertical clusters at variable angles
between 34 and 50 degrees in 4‑degree increments. A second kit allows clusters up to three units. The kit includes eight M10 bolts and eight M10
knobs. The pick‑up holes accept up to a 0.5‑inch shackle.
MYA-UPQ Mounting Yoke: Cradle‑style mounting yoke that suspends a single UPQ‑D loudspeaker and supports a wide range of horizontal and
vertical adjustment.
Galileo GALAXY Network Platform: The Galileo GALAXY Network Platform provides state‑of‑the‑art audio control technology for loudspeaker
systems with multiple zones. With immaculate sonic performance, it provides a powerful tool set for corrective room equalization and creative fine‑
tuning for a full range of applications.
MDM-832 Distribution Module: MDM‑832 units conveniently power UPQ‑D arrays, routing up to eight channels of AC power, balanced audio and
RMS signals to the loudspeakers.

NOTES
1. Loudspeaker system predictions for coverage and SPL are available in Meyer Sound’s MAPP System Design Tool.
2. Recommended maximum operating frequency range. Response depends on loading conditions and room acoustics.
3. Free‑field, measured with 1/3 octave frequency resolution at 4 m.
4. Linear Peak SPL is measured in free‑field at 4 m referred to 1 m. Loudspeaker SPL compression measured with M‑noise at the onset of limiting,
2‑hour duration, and 50 °C ambient temperature is < 2 dB.
M-noise is a full bandwidth (10 Hz–22.5 kHz) test signal developed by Meyer Sound to better measure the loudspeaker’s music performance.
It has a constant instantaneous peak level in octave bands, a crest factor that increases with frequency, and a full bandwidth Peak to RMS
ratio of 18 dB. The presence of a greater‑than (>) symbol with regard to crest factor indicates it may be higher depending on EQ and boundary
loading.
Pink noise is a full bandwidth test signal with Peak to RMS ratio of 12.5 dB.
B-noise is a Meyer Sound test signal used to ensure measurements reflect system behavior when reproducing the most common input spectrum,
and to verify there is still headroom over pink noise.
5. Peak power based on the maximum unclipped peak voltage the amplifier will produce into the nominal load impedance.
6. AC power cabling must be of sufficient gauge so that under burst current rms conditions, cable transmission losses do not cause the
loudspeaker’s voltage to drop below the specified operating range.
