ABOUT THE PRODUCT ABOUT THE MANUFACTURER GLOSSARY

UPM-1XP : Ultracompact Wide Coverage Loudspeaker

The UPM‑1XP, with IntelligentDC technology, is a compact, externally-powered, wide-coverage loudspeaker for professional sound reinforcement. It offers the same high sound pressure levels, low distortion, and uniform directional control as the UPM‑1P but with the added flexibility of external DC power—enabling lengthy cable runs without AC conduits. Ideal usage of the UPM‑1XP is for applications requiring wide‑coverage in a small, inconspicuous cabinet where AC cabling is not feasible.
As a standalone loudspeaker, use the UPM‑1XP for vocal reinforcement, frontfill coverage, or delay coverage for under‑balcony applications. For full-range systems, pair the UPM‑1XP with Meyer Sound’s UMS‑1XP ultracompact subwoofer with IntelligentDC technology.
The UPM‑1XP’s high-frequency section includes a 1-inch metal dome tweeter on a constant-directivity, high-frequency horn with a 100° beamwidth. The low/mid-frequency section includes two 5-inch cone transducers that work in parallel at low frequencies— delivering a combined acoustic output—with one of the drivers rolling off above 320 Hz to prevent interference in the crossover region due to comb filtering effects. A three-channel amplifier, which includes active crossover, driver protection, and frequency and phase correction circuitry, powers the proprietary drivers that Meyer Sound manufactures at its factory in Berkeley, California.
With IntelligentDC technology, the UPM‑1XP receives DC power and balanced audio from a single loudspeaker connector, available as Phoenix 5-pin male, sealed SwitchCraft EN3 5-pin male, or sealed ECO‑M 7-pin male. Powering the unit from an external source eliminates the need for wiring conduits while still preserving the advantages of self-powered systems. The UPM‑1XP’s amplifier and signal-processing circuits store DC power and tolerate voltage drops, thereby accommodating light-gauge cables and lengthy cable runs.
The UPM-1XP requires a Meyer Sound IntelligentDC external power supply. For larger installations, the single-space rack-mount MPS‑488HP IntelligentDC power supply unit distributes DC power and balanced audio to up to eight UPJunior‑XP loudspeakers or other Meyer Sound IntelligentDC loudspeakers. For smaller installations, the MPS-482HP IntelligentDC power supply offers two channels of audio and DC power. Composite multiconductor cables, such as Belden 1502 or equivalent, can deliver both DC power and balanced audio to loudspeakers at cable lengths up to 150 feet with just 1 dB of loss in peak SPL using 18 AWG wire. Longer cable runs are possible with heavier gauge wires.
Meyer Sound’s RMS remote monitoring system, which offers comprehensive monitoring of loudspeaker parameters from a Mac or Windows-based computer running Compass control software, is optionally available for the MPS‑488HP.
Meyer Sound coats the UPM‑1XP cabinet with a slightly textured black finish and includes three threaded, recessed nut plates (3/8 in-16 or metric M10). Optional rigging hardware includes the MYA‑UPM mounting yoke, MUB‑UPM U-bracket, and MSA‑UPM stand adapter. Other UPM‑1XP options include weather protection and custom color finishes for fixed installations and installations with 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.

Efficiency Rating: Level of sound output measured at a prescribed distance with a standard input power. Efficiency rating standard is 1 watt (2.83V at 8 ohms) at 1 meter over a specified frequency range and is measured in decibels.

Equalization: Loosely, any type of relative frequency adjustment. Specifically, the process of changing the frequency balance of an electrical signal to alter the acoustical output.

Equalizer: A component designed to alter the frequency balance of an audio signal. Equalizers may be graphic, parametric, or a combination of both.

Fade: A gradual increase in audio, i.e. a fade-up, or a gradual decrease in audio, i.e. a fade-down.

Feedback: The transmission of current or voltage from the output of a device back to the input, where it interacts with the input signal to modify operation of the device. Feedback is positive when it’s in phase with the input and negative when it’s out of phase.

FM: Frequency Modulated.

Frequency: The number of cycles (vibrations) per second. In audio, audible frequencies commonly range from 20 to 20,000 cycles per second (Hz). In video, frequency is used to define the image resolution. Low-frequency video images depict large objects or images. Higher frequencies depict smaller objects (finer details.

Frequency Response: A measure of what frequencies can be reproduced and how accurately they are reproduced. A measurement of 20 to 20,000 Hz, 3dB means those frequencies between 20 and 20,000 Hz can be reproduced no more than 3 dB above or below a reference frequency level.

Full-Range: A speaker designed to reproduce the full range (20 Hz to 20 kHz) of audio frequencies.

Gain: Increase in level or amplitude.

Gooseneck: This refers to a microphone with a flexible neck that is most frequently attached to a podium or lectern. It is designed to allow the speaker to raise or lower the microphone to a suitable height.

Graphic Equalizer: A type of equalizer with sliding controls that creates a pattern representing a graph of the frequency-response changes. Raising sliders boosts the affected frequencies lowering sliders cuts (attenuates) the affected frequencies.

HDCP: High-Bandwidth Digital Content Protection. Created by Intel, HDCP is used with HDTV signals over DVI and HDMI connections and on D-Theater D-VHS recordings to prevent unauthorized duplication of copyright material.

HDR: Hard-Drive Recorder. Device that uses a computer hard drive to store compressed digital audio and video signals.

High Pass: A filter that passes high frequencies, and attenuates low frequencies. Same as low cut.

Hz: Hertz or cycles per second. Something that repeats a cycle once each second moves at a rate of 1 Hz.

Incue/Inq/In-Point: These words all refer to the initial few seconds of audio signifying the beginning of the production.

Integrated Amplifier: A combination preamp and amplifier.

Impedance: A measure of the impediment to the flow of alternating current, measured in ohms at a given frequency. Larger numbers mean higher resistance to current flow.

KHz: Kilohertz or one thousand Hz.

Lavaliere: A small microphone that attaches to clothing, allowing the speaker to have a hands-free presentation.

Line Array: A group of speakers that have been arrayed or "built up" in the vertical or horizontal plane, which allow for a highly consistent sound field. A Line Array is perfect for medium to large audiences.

Line-Level (Low-Level): A level of electrical signals too low to make the average speaker move sufficiently. Amplifiers receive line-level signals and amplify them to speaker level.

lockout: The final words of a segment used to signify the production’s conclusion.

Low Pass: A filter that lets low frequencies go through but doesn’t let high frequencies go through. Same as high cut.

MHz: Megahertz, or 1 million Hz.

Midbass: The middle of the bass part of the frequency range, from approximately 50 to 100 Hz (upper bass would be from 100 to 200 Hz). Also used as a term for loudspeaker drivers designed to reproduce both bass and midrange frequencies.

Midrange: The middle of the audio frequency range. Also used as a term for loudspeaker drivers designed to reproduce this range.

Mixer: This is the unit in which audio signals are directed from. A mixer provides for both mic and line input combinations while allowing you to control one or more outputs.

MLP: Meridian Lossless Packing. Encoding format that is able to completely reconstruct the original signal at the receiving end. No information is lost or discarded, regardless of how trivial it might be. Used to encode six channels of high-resolution audio on DVD-A.

Mono: Monophonic sound. One channel.

MP3: MPEG-1 Audio Layer-3. Compression scheme used to transfer audio files via the Internet and store in portable players and digital audio servers.

Natural Sound (NATS): The nonverbal audio that occurs in a non-studio setting. NATS can be used to help characterize the setting.

Noise: An unwanted portion of a signal such as hiss, hum, whine, static, or buzzing.

Nonlinear Editing: Digital audio systems that allow for clips to be extracted without affecting the master recording.
