The UPM-1P is an extraordinarily compact, self-powered professional sound reinforcement loudspeaker system. It is perfect for applications necessitating a small and unobtrusive loudspeaker that can also deliver high sound pressure levels, exceptionally low distortion, and uniform directional control. The UPM-1P loudspeaker provides vocal-range reinforcement as a small PA system, or as a fill or delay loudspeaker in larger indoor or outdoor systems. Adding an optional subwoofer creates a full-range system. The UPM-1P high-frequency section includes a 1-inch metal dome tweeter on a symmetrical constant-directivity high frequency horn with 100-degree beam width. At lower frequencies, phase-correction circuitry ensures true point-source performance without the off-axis cancellation effects that afflict customary dual-woofer designs. Two 5-inch low-frequency cone drivers drive in parallel at low frequencies to benefit from their combined acoustic output. One of the drivers rolls off above 320 Hz to avert damaging interference and comb filtering effects in the mid-band frequencies close to the crossover area. The sturdy cabinet is coated with a textured black finish. Mounting is via three 3/8″-16 or metric M10 threaded recessed nut plates. Optional U-bracket, yoke, and pole-mount hardware is available. The UPM-1P loudspeaker can be supplied with either the standard audio input module incorporating looping XLR connectors, or an alternate that adds attenuation and a polarity switch.
