Overview
 
The black Shure ULXD2/K8 is a digital handheld wireless microphone transmitter compatible with ULX-D receivers. It comes equipped with a KSM8 dual-diaphragm dynamic capsule that minimizes proximity effect, delivering a consistent sound, even when the distance between the mic and the sound source varies. The cardioid polar pattern provides a clean, richly detailed signal with reduced feedback, great for speech and vocals in live venues.
 
With a rugged, yet lightweight aluminum housing, the ULXD2/K8 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 KSM8's hardened, dent-resistant grille is lined with hydrophobic woven fabric, which rejects moisture as well as plosives.
The interchangeable capsule design allows you to replace the KSM8 capsule with a Shure capsule that’s ideal for your application and simply screw it onto the transmitter—including KSM9, SM58, SM86, SM87A, Beta 58A, 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.

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.
