The Shure ULXD2/B87A is a digital handheld wireless microphone transmitter compatible with ULX-D receivers. It comes equipped with the Beta 87A supercardioid condenser capsule designed to withstand extreme sound pressure levels, while still delivering a remarkably smooth frequency response for vocal performers and presenters. The capsule features a supercardioid polar pattern that offers excellent rejection of off-axis background noise, helping to reduce feedback.

With a rugged, yet lightweight aluminum housing, the ULXD2/B87A 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 87A supercardioid condenser capsule handles SPL levels up to 140 dB and offers a smooth frequency response with a gradual presence rise and controlled proximity effect tailored for vocals

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

Cover too loose.
Size: 300A Fuse Holder
Nice looking, decent quality, versatile for different gauges. My only complaint with this holder is the cover doesn’t stay on very well, bought 3, and all 3 pop off easily, you will need to zip tie on.
