Shure QLXD24/B58 Digital Wireless Handheld Microphone System with Beta 58A Capsule

The Shure QLXD24/B58-H50 is a digital wireless handheld microphone system that pairs the trusted Beta 58A capsule with Shure’s QLX-D UHF platform. It gives vocalists, presenters, and audio technicians a straightforward way to capture focused speech or singing while keeping the signal secure and free from interference.

The included Beta 58A capsule uses a supercardioid pickup pattern that isolates the voice and helps control feedback in louder environments. Whether a singer is moving across a concert stage or a lecturer is addressing a conference hall, the capsule maintains clarity and presence without requiring constant EQ adjustments.

The system transmits 24-bit 48 kHz audio and maintains a working range of up to 330 feet. AES 256-bit encryption keeps each channel private, an advantage for corporate events, houses of worship, and broadcast applications where confidentiality and signal integrity matter. Digital Predictive Switching Diversity continuously evaluates the RF environment and chooses the best signal path before dropouts can occur, so the audience hears every word without interruption.

The half-rack receiver offers an easy-to-read display with audio and RF meters, plus one-touch IR sync that locks the transmitter to the chosen frequency in seconds. An Ethernet port lets technicians monitor and coordinate up to 60 compatible channels through Shure Wireless Workbench software, streamlining large multi-mic setups in theaters or touring rigs.

Two AA batteries power the handheld transmitter for as long as nine hours, giving performers a full show and encore without a battery swap. Detachable antennas make it simple to place remote antenna kits or integrate the receiver into a rack case when coverage needs to span a wider area.

From intimate clubs to mid-size auditoriums, the QLXD24/B58-H50 fits engineers who want predictable performance, artists who need freedom to walk the stage, and event planners who demand a professional sound without a complicated learning curve.
