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.
