The ACR EM-1A, EM-2BA, and EM-1D Portable Safety Megaphones have been designed to minimize acoustic feedback that results in whistling and other similar sounds. Each megaphone has a 90° sound projection angle so that people in the megaphone’s immediate vicinity, as well as those in the rear sections of an aircraft, can hear the message. Plus, the amplifier frequency band-pass has been selected to produce a crisp, clear reproduction of voice signals. Specific attention has been given to the physical size of the megaphone so that each model can be used effectively in a crowded environment.
