The Shure ULXD2/B87C is a digital handheld wireless microphone transmitter compatible with ULX-D and QLX-D receivers. It comes equipped with the Beta 87C cardioid condenser capsule designed to deliver an extremely smooth frequency response with extended high end for vocal performers and presenters. The capsule features a cardioid pick-up pattern that reduces rear and off-axis background noise, helping to control feedback.
With a rugged, yet lightweight aluminum housing, the ULXD2/B87C 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 87C cardioid condenser capsule offers a gradual presence rise and controlled proximity effect tailored for clear, intelligible vocals.
The interchangeable capsule design allows you to replace the Beta 87C 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 87A, KSM9 capsules, and more.
