The UPM-1P is a remarkably compact, self-powered professional sound reinforcement loudspeaker system. It is ideally suited to applications requiring a relatively small and inconspicuous loudspeaker that can also provide high sound pressure levels, extremely low distortion, and uniform directional control.
The UPM-1P loudspeaker provides vocalrange reinforcement as a small PA system, or as a fill or delay loudspeaker in larger indoor or outdoor systems. A full-range system can be created with the addition of an optional subwoofer.
The UPM-1P high-frequency section comprises a 1-inch metal dome tweeter on a symmetrical constant-directivity high-frequency horn with 100-degree beamwidth. At lower frequencies, sophisticated phasecorrection circuitry assures true pointsource performance without the off-axis cancellation effects that plague customary dual-woofer designs. Two 5-inch low-frequency cone drivers are driven in parallel at low frequencies to take advantage of their combined acoustic output. To prevent destructive interference and comb filtering effects in the mid-band frequencies close to the crossover area, one of the drivers rolls off above 320 Hz.
Two channels of power amplification are provided (350 watts total), along with an active crossover, driver protection voltage limiters, and frequency- and phaseresponse alignment circuitry. A lasertrimmed differential input stage affords superior common-mode rejection to allow long signal runs through shielded twistedpair cable. The standard UPM-1P is switchable between the 115 V AC and 230 V AC ranges.
