The Meyer Sound USM-1 is a high-powered, wide
coverage loudspeaker for professional stage moni-
toring applications. Specifically designed for tour-
ing reinforcement, the accurate, rugged USM-1 is
a biamplified system consisting of a proprietary 15-
inch low-frequency driver in a vented enclosure,
and a 70-degree high-frequency horn with a 2-inch
(throat diameter) driver.
The USM-1 is designed to be operated as a sys-
tem with the Meyer Sound S-1 Control Electronics
Unit (one S-1 per channel). The S-1 comprises
electronic crossover, Meyer Sound exclusive
SpeakerSense™ driver protection circuitry, and
amplitude and phase response alignment circuitry
optimized for the loudspeaker.
