- For Presenters and Performers
- Beta 87A Condenser Supercardioid Mic
- Handheld Transmitter
- Switching-Diversity Rackmount Receiver
TheShure QLXD24/B87Arackmount 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/B87A includes the QLXD2 handheld transmitter featuring an interchangeable capsule design and equipped with a Beta 87A condenser capsule. The supercardioid pickup pattern focuses on the voice, helping to reduce feedback on loud stages. 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.
