Shure ULXS14/83

The Shure ULXS14/83 Standard Wireless Microphone System includes WL183 Omnidirectional Lavalier Microphone, ULX1 Bodypack Transmitter, and ULXS4 Diversity Receiver.

WL183 Lavalier Microphone

The WL183 lavalier electret condenser mic was designed for use with a wireless body-pack transmitter. It has a 4 ft. (1.2 meter ) cable terminated with a miniature 4-pin mini connector. Included tie clip can be rotated in 90 degree intervals for placement flexibility. 

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.

Shure ULXS4 Standard Receiver 

The Shure ULXS4 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: www.fcc.gov/cgb/wirelessmicrophones.
