Portable Safety Megaphone

Model Number: EM-1A; EM-2BA; EM-1D / Part Number 2204; 2206; 2208

The ACR/EM-1A, ACR/EM-2BA, and ACR/EM-1D are battery-operated, solid state megaphones specifically developed for use in enclosed areas.  FAA approved.

More Information

The ACR/EM-1A, ACR/EM-2BA, and ACR/EM-1D have been designed to minimize regenerative acoustic feedback that results in whistling and other oscillations of this nature. They have a 90° sound projection angle to direct the sound to persons in their immediate vicinity, as well as in the rear sections of any aircraft. The amplifier frequency band-pass has been selected to produce a crisp, clear reproduction of voice signals. The operating power level is also sufficient to provide adequate sound under high ambient noise level conditions without being overpowering. Specific attention has been given to the physical size so that they can be used effectively in a crowded environment.
