The Shure ULXD2/KSM9 is a digital handheld wireless microphone transmitter compatible with ULX-D and QLX-D receivers. It 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 black 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.
With rugged, yet lightweight aluminum housing, the ULXD2/KSM9 transmitter delivers pristine audio quality and RF performance, AES 256-bit encryption for secure transmission, and advanced rechargeability options for professional sound-reinforcement applications.
