The Shure QLXD2/B58A is a premium digital handheld wireless microphone transmitter, designed for seamless compatibility with QLX-D receivers. Equipped with the Beta 58A dynamic capsule, it is tailored for close-up vocal performance, featuring a brightened midrange and bass roll-off to manage proximity effects. The supercardioid polar pattern ensures exceptional gain before feedback, optimal isolation from ambient sound, and minimal off-axis tone coloration.

Operating within a 64 MHz UHF tuning range, the QLXD2/B58A offers 2560 selectable frequencies, supporting up to 9 hours of continuous use with two AA batteries. It has a transmission range of up to 330 feet and selectable RF power outputs of 1 mW or 10 mW.

Housed in a durable yet lightweight aluminum chassis, the QLXD2/B58A is built for high-quality audio performance and robust RF transmission. It features AES 256-bit encryption for secure communication and advanced rechargeable options, making it ideal for medium-sized venues, houses of worship, and various A/V installations in conference, educational, and corporate settings.

Superior Audio Quality with Interchangeable Capsules

The QLXD2/B58A delivers pristine 24-bit/48 kHz digital audio. The Beta 58A capsule includes a neodymium magnet for high signal-to-noise output. The interchangeable capsule design allows you to replace the Beta 58A with other Shure capsules like the SM58, KSM8, SM87A, SM86, Beta 87A, Beta 87C, KSM9, and more, tailoring the microphone to your specific needs.

User-Friendly and Durable Design

Syncing with a wireless receiver is effortless via infrared with a single button press. The transmitter’s adjustable input sensitivity accommodates a range of vocal volumes, from loud voices to soft speech. Frequency and power lockout functions prevent accidental changes during events. A backlit LCD with an intuitive menu and controls provides quick access to frequency, group, and channel settings, as well as mute and lock status, and RF output. The selectable RF output power of 1 mW or 10 mW allows for either extended range or the operation of more microphones simultaneously.

Flexible Power Management

The QLXD2/B58A runs up to 9 hours on two AA batteries. The optional Shure SB900A lithium-ion rechargeable battery pack offers intelligent power management with over 10 hours of battery life, precise metering in hours and minutes, and no memory effect. External charging contacts facilitate docked charging with the SBC200 dual-docking charger (sold separately). Additionally, the networkable SBC220 charger (sold separately) enables remote power monitoring via Shure’s Wireless Workbench software.

With its blend of superior audio quality, secure transmission, and user-friendly features, the Shure QLXD2/B58A is an exceptional choice for professional sound reinforcement in diverse environments.
