UPA-2P : Compact Narrow Coverage Loudspeaker
The UPA-2P 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 45-degree symmetrical high-frequency horn. The versatile UPA-2P has many sound reinforcement applications, as a main front-of-house loudspeaker in smaller venues (as a stand-alone set or in arrays), as a delay or fill loudspeaker in larger systems, and more.
The UPA-2P is distinguished by the extraordinarily smooth and predictable behavior of its proprietary horn. Uniformly predictable polar behavior takes much of the guesswork out of system design, and ensures arrays that exhibit minimal destructive interference.
Each driver is individually powered by a dedicated channel of the proprietary class AB/bridged amplifier with complementary MOSFET output stages. Total power is 550 watts. The incoming audio signal is processed through an electronic crossover and correction filters for flat phase and frequency response as well as for driver protection. Phase-corrected electronics ensure flat acoustical amplitude and phase response, resulting in exceptional impulse response and precise imaging.
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).
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 on top and bottom) with a load rating of 420 lbs (190.51 kg) at a 5:1 safety factor. The optional 30-degree rigging frame, mounting yoke and pole mount adapters allow fast, flexible installation and easy aiming.
