ABOUT THE PRODUCT ABOUT THE MANUFACTURER GLOSSARY

UPQ-D2 : Narrow Coverage Loudspeaker

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 awardwining 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.

Used Meyer Sound Laboratories

Meyer Sound Laboratories is an American company based in Berkeley, California that manufactures self-powered loudspeakers, multichannel audio show control systems, electroacoustic architecture, and audio analysis tools for the professional sound reinforcement, fixed installation, and sound recording industries.
The company’s emphasis on research and measurement has resulted in the issuance of dozens of patents, including for the now-standard trapezoidal loudspeaker cabinet shape. Meyer Sound has pioneered other technologies that have become standard in the audio industry, including: processor-controlled loudspeaker systems, self-powered loudspeakers,curvilinear arraying, cardioid subwoofers, and source independent measurement.
Meyer Sound has consistently involved itself with advanced research beyond that connected to immediate product development, sometimes in conjunction with arms of the University of California, Berkeley. Some of this research has resulted in unusual products such as their parabolic sound beam and sound field synthesis loudspeakers. Other projects, such as the spherical loudspeaker research underway by Meyer Sound and CNMAT (Center for New Music and Audio Technologies) at UC Berkeley are still in the stage of pure research.

Octave: The difference between two frequencies where one is twice the other. For example, 200 Hz is an octave higher than 100 Hz. 400 Hz is one octave higher than 200 Hz.

Optical Digital Cable: Fiber optic cable that transfers digital audio signals as light pulses.

Outcue/Outq/Out-Point: These words all refer to the final few seconds of audio signifying the conclusion of the production.

Package: A completed and fully edited audio piece.

Passive: Not active. A passive crossover uses no external power and results in insertion loss. A passive speaker is one without internal amplification.

Phase: Time relationship between signals it’s all relative.

Power Output: A measure, usually in watts, of how much energy is modulated by a component.

Preamplifier: A control and switching component that may include equalization functions. The preamp comes in the signal chain before the amplifiers.

Pre Outs: Connectors that provide a line-level output of the internal preamp or surround processor.

Pre Outs/Main Ins: Connectors on a receiver that provide an interruptible signal loop between the output of the internal preamp or surround processor portion of the receiver and the input of the amplifier portion of the receiver.

Pre/Pro: A combination preamp and surround processor.

Processors: Anything that processes an incoming signal in some way. Surround processors, for example, can decode a Dolby Digital signal to send to an amp so you can hear it.

Pulse Code Modulation: (PCM) a way to convert sound or analog information to binary information (0s and 1s) by taking samples of the sound and record the resulting number as binary information. Used on all CDs, DVD-Audio, and just about every other digital audio format. It can sometimes be found on DVD-Video.

Q-and-A: Question and answer session.

Receiver: Any component that receives, or tunes, broadcast signals, be it NTSC, HDTV, DBS, or AM/FM radio. Typically refers to the single component that includes a preamp, surround processor, multichannel amplifier, and AM/FM tuner.

Reverberation: The reflections of sound within a closed space.

RF: Radio Frequency. Television signals are modulated onto RF signals and are then demodulated by your television’s tuner. VCRs and DBS receivers often include channel 3 or 4 modulators, allowing the output signal to be tuned by the television on those channels. Also, laser discs used an RF signal for modulating Dolby Digital 5.1 soundtracks on some movies. This requires an RF demodulator (usually referred to as an AC3-RF demodulator) before or in the surround processor to decode the signal.

RMS: Root Mean Square or the square root of the arithmetic mean (average) of the square’s set of values. A reasonably accurate method of describing an amplifier`s power output.

SACD: Super Audio CD. Enhanced audio format with up to six channels of high-resolution audio encoded using DSD. Requires an SACD player. Multichannel also requires a controller with six-channel analog or proprietary digital inputs for full playback.

Sampling Frequency: How often a digital sample is taken of an analog wave. The more samples taken, the more accurate the recording will be. You need to sample at a minimum of twice the highest frequency you want to capture. For example, the 44.1-kilohertz sampling rate of a CD cannot record sounds higher than 22.05 kilohertz.

Scener: A radio report in which the announcer is recorded at the same time and place as the background sound of an event.

Sensitivity: A measurement (in dB) of the sound-pressure level over a specified frequency range created by a speaker driven by 1 watt (2.83V at 8 ohms) of power with a microphone placed 1 meter away.

Signal-to-Noise Ratio: A comparison of the signal level relative to the noise level. Larger numbers are better.

Simultaneous Interpretation: This system allows attendees to hear the meeting in their own language.

Sound Bite: A portion of audio of someone speaking.

Sound field: The total acoustical characteristics of a space, such as ambience number, timing, and relative level of reflections ratio of direct to reflected sound RT-60 time etc.

Soundstage: The area between two speakers that appears to the listener to be occupied by sonic images. Like a real stage, a soundstage should have width, depth, and height.

Speaker: A component that converts electrical energy into acoustical energy.

SPL: Sound-Pressure Level. Measured in dB.

Subwoofer: A speaker designed to reproduce very low bass frequencies, usually those below about 80 Hz.

THX: Certification program for home theater equipment. Uses some proprietary features, but mostly assures a base quality level for a given room size. (See THX select or Ultra.) Is compatible with any and all soundtrack formats. Stands for either Tom Holman’s eXperiment, after the engineer who drafted the original standard, or is named after the company’s founder George Lucas first movie, THX 1138. Nobody agrees on which.

THX select: Certification program for speakers and receivers that assures a base level of quality and performance when played in a room that’s between 2,000 and 3,000 cubic feet.

User-Generated Content (UGC): Text, photos, video or audio supplied by the customers of a company.

Voicer: A radio report without background audio taken from a scene or otherwise.

Wrap: A radio report containing both the reporter and an actuality.
