The Shure ULXP24D/BETA58 Dual Handheld Wireless Microphone System includes two ULXP4 Diversity Receivers, and two ULX2 Handheld Transmitters fitted with Beta SM87A Mic capsules. 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. NOTE: Bodypack and Handheld Transmitters cannot be used simultaneously.

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 features 3-segment battery fuel gauge, frequency and power settings, and control lockout. A backlit LCD shows group and channel.

Beta 87A Vocal Microphone

The Shure Beta 57A is a high output supercardioid dynamic microphone designed for professional sound reinforcement and project studio recording. It maintains a true supercardioid pattern throughout its frequency range. This insures high gain-before-feedback, maximum isolation from other sound sources, and minimum off—axis tone coloration.

Excellent for acoustic and electric instruments as well as for vocals, the extremely versatile Beta 57A dynamic microphone provides optimal warmth and presence. Typical applications include drums, guitar amplifiers, brass, woodwinds and vocals.
