The Peltor Aviation 8103 helicopter headset has an ambient-noise compensated dynamic differential microphone, specially designed for aviation intercom
systems. The microphone amplifier is designed for intercom systems with 5 Ohm impedance. The frequency range is adjusted for good speech recognition.
The earphones have a limited frequency range, to give the best possible speech recognition in the ambient noise of a helicopter. Peltor’s two-point suspension
of the shells on a broad headband ensures total comfort and consistent noise attenuation. The spiral polyurethane cable has a moulded NATO-standard
connector equivalent to the Nexus TP-120.
