The Shure QLXD2/KSM9HS is a digital handheld wireless microphone transmitter compatible with QLX-D receivers. It comes equipped with a dual-diaphragm KSM9HS condenser capsule that captures sonic nuances with superior detail, delivering precise vocal reproduction for high-end live performance.

The KSM9HS 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 hypercardioid pattern offers excellent off-axis rejection and extended gain before feedback, making it an ideal choice in loud environments. The subcardioid pattern provides a wide coverage angle with subtle off axis-rejection, resulting in a natural sound and minimized proximity effect.

The QLXD2/KSM9HS operates on a 44 MHz UHF tuning range with 1760 selectable frequencies available. It provides up to 9 hours of operation on two AA batteries, with a transmission range up to 330' and a selectable 1/10mW RF power output.

With a rugged, yet lightweight aluminum housing, the QLXD2/KSM9HS transmitter delivers pristine audio quality and RF performance, as well as AES 256-bit encryption for secure transmission and advanced rechargeability options. It is well suited for sound reinforcement applications in medium-sized venues and houses of worship as well as A/V installations in conference, educational, and corporate facilities.
