Portable Safety Megaphone Model Number: EM-1A; EM-1D / Part Number 2204 and 2208 The ACR/EM-1A or ACR/EM-1D is a battery-operated, solid state megaphone specifically developed for use in enclosed areas. FAA approved. The ACR/EM-1A or ACR/EM-1D has been designed to minimize regenerative acoustic feedback that results in whistling and other oscillations of this nature. It has a 90? sound projection angle to direct the sound to persons in its 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 it can be used effectively in a crowded environment.
