The Modulator was an electronic siren produced by Federal Signal Corporation. Each active cell contains up to four 100W drivers, with the bottom-most cell being a dummy to direct sound from the lowest active cell outward. It is shorter and narrower than the original Modulator, making it more compact.
Models
The model number refers to the number of active cells, minus the bottom dummy cell, and drivers, of which a cell can have up to four. The first digit refers to the number of active cells in the siren and the last two refer to the number of drivers. For instance, the MOD2008 has two active cells with four drivers each, making eight drivers, plus a dummy cell on the bottom.
