The AKG DGN 99 Gooseneck Microphone is rugged, flexible and features a dynamic capsule that doesn't require phantom power. The DGN 99 features an attached 6' 4" (2m) long unterminated cable, making it easily installed in paging systems. Its cardioid polar pattern eliminates unwanted off-axis noise while providing a generous pickup pattern, and the frequency response is tailored to maximize the intelligibility of speech.
