Shure QLXD24/SM58-G50 QLXD2/SM58 Handheld Transmitter with QLXD4 Wireless Receiver

The Shure QLXD24/SM58 rackmount digital wireless handheld microphone system provides performers, presenters, and broadcasters with professional-quality audio, reliable RF performance, and secure AES 256-bit encryption. Rugged and easy-to-use, it is ideal for sound-reinforcement applications in medium-sized venues and houses of worship as well as A/V installations in conference, educational, and corporate facilities.

The system operates in the UHF band to transmit pristine 24-bit/48 kHz digital audio with clarity, accurate low end, and crisp transient response. It utilizes Digital Predictive Switching Diversity to protect the transmission from interference and deliver solid RF signal stability without audio artifacts. You can run up to 60 mic channels at the same location.

The QLXD24/SM58 includes the QLXD2 handheld transmitter featuring an interchangeable capsule design and equipped with the legendary SM58 cardioid dynamic capsule, an industry standard for vocalists and presenters. The lightweight transmitter provides up to 9 hours of operation on two AA batteries, with selectable 1/10mW RF power and a transmission range up to 330'.

The receiver features audio and RF meters, 60 dB of gain control, and both mic/line XLR and 1/4" instrument outputs. A large LCD screen and intuitive controls let you quickly make adjustments, even in low-light situations. Additional features include automatic frequency scanning, IR sync, and internal limiting to prevent clipping.

The Ethernet port allows multiple receivers to be easily networked together for simplified frequency coordination and deployment via Shure's Wireless Workbench (WWB) software
