Megaphone
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.

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. Only available through Kellstrom Aerospace.
