The Shure QLXD2/SM58 is a digital handheld wireless microphone transmitter compatible with QLX-D receivers. It comes equipped with the legendary SM58 dynamic capsule, an industry standard for vocal performers and presenters. The capsule features a cardioid polar pattern that minimizes background noise and feedback, and its brightened midrange and bass roll off gives you that sought-after warm and clear vocal reproduction.

The QLXD2/SM58 operates on a 64 MHz UHF tuning range with 2560 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/SM58 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.

Clear, Accurate Audio with Interchangeable Capsule
The unit delivers clear, reliable 24-bit/48 kHz digital audio.

User-Friendly Features in a Rugged Housing
The unit quickly syncs with a wireless receiver via infrared at the touch of a button.
