Shaped frequency response, directionality, and distant sound discrimination contribute to total noise reduction. The microphone operates on the pressure-gradient principle and has 2 sound entry ports spaced a small distance apart.
Modular design greatly facilitates field servicing. The cartridge, switch, and cable can be replaced in a matter of minutes.
