The Shure QLXD2/KSM8 is a digital handheld wireless microphone transmitter compatible with QLX-D and ULX-D receivers. It comes equipped with a KSM8 dual-diaphragm dynamic capsule that minimizes proximity effect, delivering a consistent sound even when the distance between the mic and the sound source varies. The cardioid polar pattern provides a clean, richly detailed signal with reduced feedback, great for speech and vocals in live venues.
The QLXD2/KSM8 operates on a 42 VHF tuning range with 1680 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/KSM8 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.
