Shure ULXP24/58 Handheld Wireless Microphone System
The Shure ULXP24/58 is a wireless professional handheld microphone system that features the ULXP4 Diversity Receiver and the ULX2 Handheld Transmitter fitted with the SM58 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 guage, Backlit LCD shows group and channel, Frequency and power settings, and Control lockout.
SM58 Vocal Microphone
The Shure SM58 unidirectional (cardioid) 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. A cardioid pickup pattern isolates the main sound source while minimizing unwanted background noise. Rugged construction, a proven shock-mount system, and a steel mesh grille ensure that even with rough handling, the SM58 will perform consistently, outdoors or indoors. Consistently the first choice of performers everywhere.
