Professional grade.

The Shure ULXS24/58 is a handheld wireless microphone system that includes the ULX2 Handheld Transmitter fitted with the SM58 Microphone 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 wireless systems offer more advanced features and controls, including lockable settings and a group scan function. Over 1400 selectable, pre-programmed frequencies are available and Automatic Frequency Selection provides a straight shot to a clear channel.

ULX2 Handheld Transmitter

The ULX2 Handheld Transmitter features 3-segment battery fuel gauge, frequency and power settings, and control lockout. Backlit LCD shows group and channel.

SM58 Vocal Microphone

The SM58 unidirectional dynamic vocal microphone is designed for professional vocal use in live performance, sound reinforcement, and studio recording. It has a tailored vocal response tuned to accentuate the warmth and clarity of lead and back-up vocals. A highly effective, built-in spherical filter minimizes wind and breath "pop" noise. The cardioid pickup pattern isolates the main sound source while minimizing unwanted background noise. Rugged construction, a proven shockmount system, and a steel mesh grille ensure that even with rough handling. The SM58 has consistently been the first choice of performers everywhere.

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 FCCs wireless microphone website at:
