Shure QLXD2/B87A — Handheld Wireless Transmitter with Beta 87A Capsule
QLXD2/B87A Overview
The Shure QLXD2/B87A combines the QLXD2 handheld transmitter with the renowned Beta 87A supercardioid condenser capsule, purpose-built for professional wireless vocal applications. Operating in the J50A band (572–616 MHz), it delivers 24-bit digital audio quality with highly efficient RF spectrum usage, making it well-suited for RF-dense environments. IR sync with a compatible QLXD receiver enables fast, reliable channel coordination at the push of a button, and the system maintains clear, uninterrupted signal over a range of 100 m (330 ft.). This system is an ideal choice for audio engineers, system integrators, houses of worship, music venues, and presentation facilities requiring dependable wireless vocal performance.
All-metal construction provides the durability required for touring and installed applications, while compatibility with a wide selection of Shure capsules gives operators flexibility to match the microphone’s sonic character to the application.
