The Modulator II is an electronic siren produced by Federal Signal Corporation. It is the second generation in the Modulator series. It is comprised of cells that contain four compression driver speakers a piece, with a "dummy" cell that is empty to help even out sound distribution.

How it Works

The siren is made up of cells that contain four 100 watt compression driver speakers a piece. The sound is projected downward through an opening underneath each cell, it then bounces off the top of the cell underneath the opening and is projected outward. The bottom cell is a "dummy" cell that does not contain any speakers, it is used to help even out the sound distribution from the last active cell in the stack.

Differences from the Modulator

It differs from the Modulator in that it is a shorter and thinner siren making it more compact.

The MOD6032 and MOD6048 models are replaced the MOD 8032B model which is a smaller more compact model.
