The UPM-1P is a professional self-powered loudspeaker from Meyer Sound, designed to provide high-fidelity sound reinforcement in applications that require an ultra-compact format. Despite its discreet size, the UPM-1P delivers high sound pressure levels with minimal distortion and uniform directional control, making it a versatile solution for a wide variety of indoor and outdoor environments.

Ideal as a compact PA system or as a fill or delay loudspeaker in larger configurations, its response in the vocal range is accurate and articulate. With the addition of an optional subwoofer, it can become a full-range system, providing complete, balanced reinforcement across the entire frequency spectrum.

The UPM-1P features a 1-inch metal dome tweeter mounted on a symmetrical constant-directivity horn with 100° coverage, ensuring even sound distribution. A sophisticated phase correction circuit in the low frequencies ensures a true point-source response with no off-axis degradation. The exclusive crossover design eliminates phase interference, offering excellent midrange clarity.

The cabinet has a black textured finish and features two PowerCon connectors for easy power daisy-chaining. It includes three threaded inserts for flexible mounting options (3/8”-16 or M10), as well as a range of optional hardware such as U-brackets, yokes and pole adapters.

The UPM-1P can be configured with a standard XLR audio input with loop output, or with a version that includes gain control and a polarity switch. It is also compatible with the optional RMS™ remote monitoring system, which displays key parameters such as signal levels, temperature, transducer status and limiter activity on a Windows® computer.

Also available in weather-protected versions and custom finishes, the UPM-1P adapts perfectly to both portable applications and fixed installations where aesthetics and discretion are priorities.
