Shure ULXD2/B58 Digital Handheld Wireless Microphone Transmitter with Beta 58A Capsule (G57: 470 to 608 MHz)

The Shure ULXD2/B58 is a digital handheld wireless microphone transmitter compatible with ULX-D receivers. It comes equipped with a Beta 58A dynamic capsule designed for close-up vocals, with brightened midrange and bass roll-off to control proximity effect. The capsule features a supercardioid polar pattern that ensures high gain before feedback, maximum isolation from other sound sources, and minimum off-axis tone coloration.

With a rugged, yet lightweight aluminum housing, the ULXD2/B58 transmitter delivers pristine audio quality and RF performance, AES 256-bit encryption for secure transmission, and advanced rechargeability options for professional sound-reinforcement applications.

Clear, Accurate Audio with Interchangeable Capsule

The unit delivers clear, reliable 24-bit/48 kHz digital audio over its entire 330' range, great for live performances and presentations in music venues, houses of worship, and conference spaces.

The Beta 58A features a neodymium magnet for high signal-to-noise output

The hardened steel-mesh grille resists wear and abuse

The interchangeable capsule design allows you to replace the Beta 58A capsule with a Shure capsule that’s ideal for your application and simply screw it onto the transmitter—including KSM9, KSM8, SM58, SM86, SM87A, Beta 87A, Beta 87C capsules, and more.

User-Friendly Features in a Rugged Housing

The transmitter offers an ultrawide 138 MHz tuning range from 470 to 608 MHz, allowing you to use it across a wide geographical range with a compatible ULX-D receiver.

The unit quickly syncs with a wireless receiver via infrared at the touch of a button.

Shure Proprietary Gain Ranging automatically adjusts the mic input level, eliminating the need for transmitter gain adjustments.

The power button conveniently doubles as mute switch, while preserving RF lock.

Frequency and power lockout functions prevent accidental or unauthorized changes during events.

A backlit LCD with easy-to-navigate menu and controls lets you quickly access frequency, group, and channel settings, along with mute and lock status, RF output, and remaining battery life.

1/10/20mW selectable RF output power allows you to increase either the transmitter's range or the number of mics operating simultaneously.

Convenient Power Management Options

Operates for up to 11 hours on two AA batteries.

Optional Shure SB900B lithium-ion rechargeable battery pack offers intelligent power management with over 8 hours of battery life, precision metering in hours and minutes, and zero memory effect.

External charging contacts allow for docked battery charging with the SBC200 dual-docking charger (available separately).

The networkable SBC220 charger (available separately) allows for remote power monitoring via Shure’s Wireless Workbench software.
