The Shure ULXP24/BETA58 Handheld Wireless Microphone System includes the ULX2 Handheld Transmitter fitted with the Beta 58A Microphone capsule, and the ULXS4 Diversity Receiver. Shure ULX Standard UHF systems represent a breakthrough in performance and price for both working musicians and professional sound installers. ULX Professional systems offer more advanced features and controls, including lockable settings and group scan function. Over 1400 selectable, pre-programmed frequencies are available, and Automatic Frequency Selection provides a straight shot to a clear channel.

ULXP4 Professional Diversity Receiver
The ULXP4 is single receiver that includes a PS41US power supply, four 1/2- wave antennas, plus rackmounting and link hardware. The expanded feature set of the ULXP4 wireless receiver offers a direct path to full, clear audio signals. Advanced settings and controls include lockable settings, automatic frequency selection, group scan function, and predictive diversity.
ULX2 Handheld Transmitter

The ULX2 Handheld Transmitter has a 3-segment battery fuel guage, Backlit LCD shows group and channel, Frequency and power settings, and Control lockout.

Beta 58A Vocal Microphone

Designed for professional sound reinforcement and project studio recording, the Shure Beta 58A maintains a true supercardioid pattern throughout its frequency range. This insures high gain before feedback, maximum isolation from other sound sources, and minimum off-axis tone coloration. The high-output Beta 58A has a shaped frequency response that is ideal for close”up vocals. The superb performance of this microphone is not affected by rough handling because of its rugged construction, proven shock mount system, and hardened steel mesh grille. It has become a leading choice among vocalists and touring professionals worldwide.

Consumer Alert:

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. For more information, call the FCC at 1-888-CALL-FCC (TTY: 1-888-TELL-FCC) or visit the FCCs wireless microphone website at:
