The Shure QLXD2/B58A is a digital handheld wireless microphone transmitter compatible with QLX-D and ULX-D receivers. It comes equipped with a Beta 58A dynamic capsule designed for close-up vocals, with brightened midrange and bass roll-off to control proximity effect. The capsule features a supercardioid polar pattern that ensures high gain before feedback, maximum isolation from other sound sources, and minimum off-axis tone coloration.

The QLXD2/B58A operates on a 42 MHz 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/B58A 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.
