MEYER SOUND UPM-1P: ULTRA-COMPACT WIDE COVERAGE LOUDSPEAKER:

The Meyer Sound UPM-1P is a remarkably compact, self-powered professional sound reinforcement loudspeaker system. It is ideally suited to applications requiring a relatively small and inconspicuous loudspeaker that can also provide high sound pressure levels, extremely low distortion, and uniform directional control.

MEYER SOUND UPM-1P FEATURES:

• Exceptional fidelity and power capability in an ultra-compact package
• Wide, symmetrical pattern covers broad listening areas
• Unique crossover design eliminates combing for consistent midrange response
• Metal dome driver delivers exceptionally smooth high-frequency characteristic

MEYER SOUND UPM-1P APPLICATIONS:

• Front and under-balcony fill
• Theatrical sound reinforcement
• Portable and installed audio-visual systems
• Cinema surround sound and effects
• Compact voice reinforcement systems

The Meyer Sound UPM-1P loudspeaker provides vocalrange reinforcement as a small PA system, or as a fill or delay loudspeaker in larger indoor or outdoor systems. A full-range system can be created with the addition of an optional subwoofer.

The Meyer Sound UPM-1P high-frequency section comprises a 1-inch metal dome tweeter on a symmetrical constant-directivity high-frequency horn with 100-degree beamwidth. At lower frequencies, sophisticated phasecorrection circuitry assures true pointsource performance without the off-axis cancellation effects that plague customary dual-woofer designs. Two 5-inch low-frequency cone drivers are driven in parallel at low frequencies to take advantage of their combined acoustic output. To prevent destructive interference and comb filtering effects in the mid-band frequencies close to the crossover area, one of the drivers rolls off above 320 Hz.

Two channels of power amplification are provided (350 watts total), along with an active crossover, driver protection voltage limiters, and frequency- and phaseresponse alignment circuitry. A lasertrimmed differential input stage affords superior common-mode rejection to allow long signal runs through shielded twistedpair cable. The standard UPM-1P is switchable between the 115 V AC and 230 V AC ranges. A 100 V AC version is also available. The UPM-1P’s integral power supply suppresses high-voltage transients, while two PowerCon AC connectors facilitate AC looping.

The rugged cabinet is coated with a textured black finish. Mounting is via three 3/8"-16 or metric M10 threaded recessed nut plates. Optional U-bracket, yoke, and pole-mount hardware is available. The UPM-1P loudspeaker can be supplied with either the standard audio input module incorporating looping XLR connectors, or an alternate that adds attenuation and a polarity switch. The UPM-1P easily integrates with the RMS™ remote monitoring system network and software (optional). RMS displays signal and power levels, driver status, limiter activity, and amplifier temperature on a remote Windows® computer.

Options available for the Meyer Sound UPM-1P cabinet include weather protection and finishes in custom colors for fixed installations and situations requiring specific cosmetics.
