Toa SM-25M Instruction Manual

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 ¼" 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 innovative design in
portable package with a wide range of applications.
