TOA SPEAKER SYSTEM
POWERED MONITOR SPEAKER
SM-25M
GENERAL DESCRIPTION
The TOA SM-25M is a self-powered personal monitor system
designed around our popular SM-25A powered monitor
system. The SM-25M has a built-in 25-watt power amp, a 5-
inch woofer and a 2-inch tweeter. An automatic compression
circuit is provided to ensure maximum headroom and speaker
component protection.
The system features a mic level XLR input on the front panel, as
well as a rotary volume control, a tone control, and headphone
monitoring jack. Add to that a back panel with both a line level
1/4" input jack and a bridging jack for chaining additional
speakers, and the SM-25M becomes a portable PA monitor
system....just plug in a microphone and go. A unique bracket
allows the system to be mounted to mic stands, and even to
walls in permanent installations. The cast aluminum enclosure
is rugged enough to withstand even the roughest handling. The
SM-25M combines high performance, durability, and in-
novative design in portable package with a wide range of
applications.
