PROFESSIONAL SOUND SPEAKER SYSTEM

General Description

The SM-25A is a small monitor speaker system with a built-
in power amplifier (with compressor circuit) of 25W, and
incorporates a high efficient, durable 2-way speaker of 12
cm (5-inch) and 5cm (2-inch) diameter. The built-in power
amplifier has a continuously variable SLIDE VOLUME
control and a BRIDGE connector is provided to facilitate
stacking two or more SM-25A. A headphones jack permits
monitoring through headphones, which masks an ambient
noise. An enclosure is made of cast aluminum, so that it is
rugged and can withstand rough use. With an optional
bracket, the SM-25A is mountable on the microphone
stand, microphone stand shaft and wall.
