The Meyer Sound UPJ-1P is a compact, self-powered loudspeaker renowned for its precise pattern control and versatile application in both fixed installations and portable sound systems. As part of the VariO™ series, its defining characteristic is a mechanically rotatable horn, allowing the user to orient the loudspeaker in either a vertical or horizontal configuration without altering its acoustic performance. This unique feature enables the same loudspeaker model to serve as a main system element, a front fill, a delay speaker, or an effects channel simply by changing its physical orientation, which correspondingly changes the coverage pattern to best suit the application. The integrated power amplifier and dedicated processing ensure the transducer operates within its optimal parameters, delivering consistent, predictable sound quality directly aligned with Meyer Sound's rigorous performance standards.

This loudspeaker utilizes a two-way design, combining a high-power low-frequency driver with a high-frequency compression driver coupled to the rotatable horn. The integrated electronics include meticulously tuned crossover filtering, equalization, and sophisticated protection limiting, all derived from the comprehensive library of presets within Meyer Sound's system controllers. This integration guarantees that the loudspeaker performs exactly as engineered, with transparent sonic character, high intelligibility, and the ability to produce significant acoustic output from a relatively small enclosure. Its focused coverage pattern minimizes unwanted reflections from walls and ceilings, providing greater control over the sound field and improving clarity, especially in acoustically challenging spaces.

Housed in a rugged, trapezoidal enclosure constructed from durable plywood with a textured urethane finish, the UPJ-1P is built for longevity in demanding environments. Multiple integrated rigging points offer flexible mounting options for permanent installation using compatible brackets or for temporary deployment on tripod stands. The loudspeaker's combination of self-powered convenience, exceptional pattern control via the rotatable horn, and proven reliability has made it a preferred choice for a wide range of professional applications, including theaters, houses of worship, conference facilities, broadcast studios, and touring shows where consistent, high-fidelity reproduction and deployment flexibility are critical requirements.
