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 IntelligentAC™
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.
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
®
rigging options include the MPA-UPQ pickup and
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.
NOTE: Complete acoustical, electrical and
physical specifications are covered in
Appendix C on page 41.
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.
