USW-1P Compact Subwoofer

Features & Benefits •  Classic design configuration with proven heritage • High peak power capability for excellent transient reproduction • Compact cabinet satisfies a broad range of installation requirements • Flat phase response for optimal crossover to mid/high systems

Applications •  Concert halls and night clubs • Theatrical sound reinforcement • Surround sound presentations • Houses of worship • Portable and installed audio-visual systems

The USW-1P is a self-powered subwoofer loudspeaker that provides flat response in the 32 - 180 Hz range. The USW-1P performs well with UPA-P Series self-powered loudspeakers to form full-range reproduction systems, and is also compatible with other Meyer Sound self-powered mid-high loudspeakers.

The USW-1P cabinet houses two 15-inch drivers, each powered by a dedicated channel of the proprietary built-in class AB/bridged amplifier (350 watts per channel) with complementary power MOSFET output stages. Each channel features a protection limiter that prevents driver over-excursion and regulates voice coil temperature, allowing high output levels across the drivers' entire frequency range.

The USW-1P input incorporates a built-in crossover and accepts a full-range signal, allowing for simple daisy-chain signal distribution and eliminating the need for external crossovers. The USW-1P also incorporates an Intelligent AC power supply, which auto-selects the correct operating voltage for international use, suppresses voltage transients, and provides soft-start power-up.

The USW-1P is compatible with Meyer Sound’s RMS remote monitoring system. RMS displays signal and power levels, limiter activity and amplifier temperature for all loudspeakers in the network on a Windows-based PC.

Combining advanced loudspeaker technology with equally advanced power capabilities, the Meyer Sound USW-1P self-powered subwoofer provides flat, low-frequency response from 35 Hz to 180 Hz. The

USW-1P performs seamlessly within a full-range system, in conjunction with UPA-1P, UPA-2P and UPJ-1P loudspeakers. The USW-1P is also fully compatible with other

Meyer Sound self-powered loudspeakers.

The USW-1P cabinet houses two 15-inch drivers, each powered by a dedicated channel of the proprietary built-in class AB/bridged power amplifier (550 watts total peak power) with complementary MOSFET output stages. Each channel incorporates a limiter that prevents driver over-excursion and regulates the voice coil temperature.

A smooth limiting characteristic effectively protects the drivers without the compression effects imposed by typical limiters, allowing high output levels across the drivers’ entire frequency range.

UPA-1P

•  Exceptional fidelity, power capability and extended high-frequency performance • Extraordinarily flat amplitude and phase response for tonal accuracy and precise imaging • Wide, symmetrical pattern covers broad listening areas • Constant-Q horn affords uniform response throughout the coverage area • Predictable array performance ensures system design flexibility • Surprising power capability in a compact package

Applications •  Concert halls, clubs, houses of worship • Theatrical sound reinforcement • Portable and installed audio-visual systems • Cinema surround sound and effects • Compact voice reinforcement systems • Frontfill and under balcony

The UPA-1P loudspeaker provides high power output, low distortion, and consistent polar response in a compact, vented two-way enclosure. The loudspeaker features a 12-inch cone low-frequency driver and a 3-inch-diaphragm compression driver coupled with a 100-degree horizontal by 40-degree vertical constant-Q horn. The versatile UPA-1P has many sound reinforcement applications, as a main front-of-house loudspeaker in small to mid-sized venues, as a fill loudspeaker in larger systems, and more.

The UPA-1P is distinguished by the extraordinarily smooth and predictable behavior of its proprietary high-frequency horn. The result of intensive research in Meyer Sound's anechoic chamber, the patented UPA-1P horn design exhibits constant Q. The beam-width remains consistent within close tolerances, in both the horizontal and vertical planes and across the horn's operating frequency range of 1200 Hz to 18 kHz. The result is uniform attenuation of all frequencies outside the specified beamwidth with minimal side lobing. Uniformly predictable polar behavior takes much of the guesswork out of system design and assures arrays that exhibit minimal destructive interference.

The UPA-1P is biamplfied with a proprietary two-channel, class AB/bridged power amplifier with complementary MOSFET output stages. Total peak power output is 550 watts; audio is processed through an electronic crossover and correction filters for phase and frequency response, as well as driver protection circuitry. Phase-corrected electronics ensure flat acoustical amplitude and phase response, resulting in exceptional impulse response and precise imaging.

The field-replaceable amplifier/processing package incorporates Meyer Sound's Intelligent AC, which auto-selects the correct operating voltage, suppresses high voltage transients, filters EMI and provides soft-start power-up. The high common-mode rejection of the laser-trimmed differential input circuit permits long signal runs through a simple shielded twisted-pair cable. Audio input modules accommodate a range of applications. The standard version offers looping XLR input and output connectors, while an enhanced looping version adds polarity switching (the looping output is not affected) and input attenuation (0 dB to -18 dB). A summing mono version with two inputs is also available.

The durable trapezoidal enclosure is covered with a black textured hard-shell finish. A protective hex-stamped steel grille and charcoal grey foam cover are included. Standard rigging points are four ring and stud pan fittings (two each, top and bottom) with load rating of 420 lbs (190.51 kg) at a 5:1 safety factor. Adjustable yokes and pole mount adaptors are available. Options include weather protection, custom color finishes, and cabinets with no handles for fixed applications requiring specific cosmetics.

The UPA-1P is compatible with the RMS remote monitoring system, which offers comprehensive monitoring of system parameters on a Windows-based network.
