The Shure ULXP24/SM86 is a professional quality wireless handheld microphone system that features the ULXP4 Diversity Receiver and the ULX2 Handheld Transmitter fitted with the SM86 Handheld Mic. 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 Wireless Diversity Receiver

The expanded feature set of the ULXP4 wireless receiver, with advanced settings and controls including lockable settings and group scan, offers a direct path to full, clear audio signals. The ULXP4 offers an exceptional value in both performance and price, for both working musicians and sound installers.

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.

SM86 Vocal Microphone

The Shure SM86 is a unidirectional (cardioid) condenser vocal microphone for professional use in live performance. An extremely rugged microphone, the SM86 withstands the rigors of touring while delivering studio-quality sound. The tailored frequency response of the SM86 reproduces vocals with clarity. A cardioid pickup pattern isolates the main sound source while minimizing unwanted background noise. The built-in three-point shock mount minimizes handling noise, and a two-stage pop filter reduces wind and breath "pop" noise.

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:
