Shure ULXS24/BETA58 Handheld Wireless Microphone System

The Shure ULXS24/BETA 58 is a handheld wireless microphone system that includes the ULX2/87 Handheld Transmitter with Beta 58A Microphone, and the ULXS4 Diversity Receiver.

ULX2 Handheld Transmitter

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

Beta 58A Vocal Microphone

The Shure Beta 58A is a high-output supercardioid dynamic vocal microphone designed for professional sound reinforcement and project studio recording. It has become a leading choice among vocalists and touring professionals worldwide.

The 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 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.

ULXS4 Diversity Receiver

The Shure ULX Standard receiver offers an exceptional value in both performance and price, for both working musicians and sound installers. The feature set of the versatile ULXS4 receiver offers a direct path to full, clear audio signals, unencumbered and unattached.

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 FCC's wireless microphone website at: www.fcc.gov/cgb/wirelessmicrophones.
