coverage loudspeaker for professional stage moni-
toring applications. Specifically designed for tour-
ing reinforcement, the accurate, rugged USM-1 is

and a 70-degree high-frequency horn with a 2-inch

The USM-1 is designed to be operated as a sys-
tem with the Meyer Sound S-1 Control Electronics

electronic crossover, Meyer Sound exclusive
SpeakerSense™ driver protection circuitry, and
amplitude and phase response alignment circuitry
