The Shure ULXD2 is a handheld wireless transmitter compatible with ULX-D™ Digital Wireless Systems. With a rugged yet lightweight aluminum body and integrated antenna, the ULXD2 delivers uncompromising audio quality and RF performance, AES 256-bit encryption for secure transmission, and advanced rechargeability options for professional sound reinforcement applications.
Most users do not need a license to operate this wireless microphone system. Nevertheless, operating this microphone system without a license is subject to certain restrictions: the system may not cause harmful interference; it must operate at a low power level (not in excess of 50 milliwatts); and it has no protection from interference received from any other device. Purchasers should also be aware that the FCC is currently evaluating use of wireless microphone systems, and these rules are subject to change.

Features:
30 Hz–20 kHz range with flat frequency response (actual response is microphone dependent)
Interchangeable Shure microphone cartridges, including the legendary SM58®
AES 256-bit encryption for applications for which secure transmission is needed
Proprietary Shure Gain Ranging optimizes the system’s dynamic range for any input source, eliminating the need for transmitter gain adjustments
