The ADX2FD/K9N comes equipped with a dual-diaphragm KSM9 condenser capsule that captures sonic nuances with superior detail, delivering precise vocal reproduction for high-end live performance. The KSM9 capsule offers two switchable polar patterns to provide FOH engineers with more choices in dealing with varying environments or the microphone techniques of different performers. The cardioid pattern offers solid gain before feedback, with minimal off-axis coloration, for a warm, full sound. The supercardioid pattern offers increased sound isolation and gain before feedback; an ideal choice for applications where there are high levels of ambient noise, or where multiple instruments or vocalists are close together.
