Active Stage Monitor with Precise Coverage and Low Distortion

The UM-1P is a self-powered stage monitor designed to deliver accurate, coherent mix reproduction in professional live applications. Its 2-way design includes a 12-inch cone driver and a 3-inch compression driver, both powered by bridged class AB amplifiers with a total output of 550 W. A flat phase and amplitude frequency response allows reliable monitoring with minimal susceptibility to feedback.

It features a symmetrical 45° x 45° coverage pattern and a constant-directivity horn, allowing multiple monitors to be installed without cross-interference. The system integrates digital processing with an electronic crossover, correction filters and component protection, along with an interchangeable input module and optional versions with gain and polarity control.

Self-powered monitor

2-way with constant directivity, flat response and high SPL. A self-powered stage monitor designed for accurate reproduction.

The Meyer Sound UM-1P is a self-powered stage monitor designed for professional live sound applications that require high precision and coverage control. It incorporates a two-way system with a 12-inch cone driver and a compression driver with a 3-inch diaphragm, both driven by bridged class AB amplifiers with complementary MOSFET output stages. Total power reaches 550 W, providing a maximum sound pressure level of 133 dB SPL at 1 meter with extremely low distortion.

The internal processing system includes an active crossover, response correction filters and transducer protection. The phase correction applied in the electronics allows a flat response in both frequency and phase, ensuring excellent impulse response. Its constant-Q coverage design, with a symmetrical 45° horizontal and vertical pattern, provides effective control of the sound field and minimizes interaction between adjacent monitors.

The enclosure is made of birch plywood with a black textured finish and features a powder-coated metal grille, internal protective foam and recessed handles. The system includes field-replaceable input modules, with options for polarity reversal, adjustable attenuation and mono signal summing. It is also compatible with Meyer Sound’s RMS remote monitoring system and features the Intelligent AC power system for safe operation worldwide.
