Shure ULXD2/B58 Digital Handheld Wireless Microphone Transmitter with Beta 58A Capsule (K51)

The Shure ULXD2/B58 is a digital handheld wireless microphone transmitter compatible with ULX-D and QLX-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.
