• The microphone amplifier is designed for intercom systems with 5 Ohm impedance
• The frequency range is adjusted for good speech recognition and the earphones have a limited frequency range, to give the best possible speech recognition in the ambient noise of a helicopter
• The spiral polyurethane cable has a moulded NATO-standard connector equivalent to the Nexus TP-120
