Overview
Meyer Sound’s UPQ‑D2 narrow 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-winning product line. UPQ‑D2 features:
A narrow coverage, Constant‑Q horn with ‑6 dB points at 50° x 50° (‑10 dB points at 60° x 60°)
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‑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. The Constant‑Q horn’s smooth and accurate performance, the result of meticulous research in Meyer Sound’s anechoic chamber, exhibits a remarkably consistent beamwidth in both the horizontal and vertical planes across a wide frequency range of 1–18 kHz. The UPQ‑D2 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.
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‑D2’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‑D2 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‑D2 provides extremely high power output with low distortion in a vented two‑way enclosure. The UPQ‑D2’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 the MYA‑UPQ mounting yoke. Other options include Meyer Sound weather protection and custom color finishes for specific cosmetic requirements.
