OVERVIEW

Professional grade.

The Shure ULXP 14/51 Wireless Professional Lavalier System features a ULXP4 Diversity Receiver, a ULX1 Bodypack Transmitter, and the WL51B Lavalier Mic. 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 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.

ULX1 Wireless Bodypack Transmitter

The low-profile, highly durable body-pack ULX1 has all the characteristics to meet the demands of high performance. For use with headworn, lavalier and instrument microphones, as well as guitars and basses. Attaches to belt, waistband or guitar strap with clip for hands-free mobility.

WL51B Lavalier Microphone
Shure's WL51B lavalier microphone sets a new standard for miniature microphones. Visually unobtrusive, the WL51B provides uncompromised sound quality and high reliability with minimal visibility in sound reinforcement applications such as television broadcasting and stage performances. Despite its small size, the microphone's condenser element provides full, clear and natural reproduction of speech.
