Shure ULXD2/B58 Digital Handheld Wireless Microphone Transmitter with Beta 58A Capsule (H50: 534 to 598 MHz)

The Shure ULXD2/B58=-H50 is a digital handheld transmitter that pairs the proven Beta 58A dynamic capsule with Shure’s ULX-D wireless platform. It gives vocalists, presenters, and audio engineers a quick path to clear sound and dependable RF performance while working seamlessly with any ULX-D receiver.

The Beta 58A capsule uses a supercardioid pickup pattern that focuses on the performer’s voice and helps keep stage bleed, background noise, and feedback under control. Because the head is interchangeable, you can swap in other Shure capsules if the show or artist requires a different sonic character.

Audio travels as 24-bit, 48 kHz digital data, so every nuance reaches the mixer without the hiss or companding artifacts that often color analog systems. AES 256-bit encryption is available for events that demand privacy, such as corporate keynotes or worship services that stream live. With a line-of-sight range of up to 100 meters, the transmitter provides consistent coverage in small clubs, large theaters, and convention halls alike.

The H50 band covers 534 to 598 MHz, a portion of the spectrum that remains open in many regions. Selectable RF output levels of 1, 10, or 20 mW let you tailor the signal to crowded urban environments or wide-open outdoor stages. IR sync locks settings to the receiver in seconds, and a backlit LCD keeps frequency, battery status, and gain adjustments in plain view even under low lighting.

Power flexibility makes the unit easy to plan around. Two standard AA batteries deliver up to 11 hours of operation, while the optional SB900A rechargeable battery pushes runtime past 12 hours and enables accurate charge readouts on both the transmitter and compatible chargers.

Whether you are a touring vocalist who needs a dependable workhorse night after night, an event production company that swaps capsules to fit different speakers, or a house-of-worship tech aiming for secure digital transmission, the ULXD2/B58=-H50 is built to slot into your workflow and stay there.
