GENERAL DESCRIPTION
The SS741MG Remote Siren Amplifier is a premium 200W unit designed for
dual 100W speaker use. It comes standard with a remote control head and a noise-
cancelling microphone for PA use. The amplifier box contains two separate
amplifiers that allow the user to operate two separate and distinct tones at the same
time. This dual tone (Magnum) feature creates a unique sound that is one of the
most attention getting amplifiers on the market today. The Magnum sound allows a
single vehicle to sound like several vehicles traveling at the same time. Each
amplifier operates one 100W RMS speaker and has its own fuse.
The primary operating modes are Phaser, Yelp, Wail, Hands Free, Manual,
Alert, and Radio. A Noise Cancelling PA Override and push-button Horn Override
are available in all modes. A manual push-button is provided for push-on/push-off
tone toggle operation in the Phaser, Yelp, and Wail modes. It also allows manual
siren control in the Manual, Alert or Hands Free modes. The Phaser function can be
optionally replaced by Two -Tone, or disabled entirely, with program jumpers.
