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.
