The Shure ULXP24D/BETA 87 Wireless Microphone System includes two ULXP4 Diversity Receivers, and two ULX2 Handheld Transmitters fitted with Beta 87C Mic capsules. The ULX Professional wireless systems offer 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 features 3-segment battery fuel gauge, frequency and power settings, and control lockout. A backlit LCD shows group and channel. Beta 87C Vocal Microphone
The Beta 87C premium vocal microphone delivers studio-grade performance and a smooth, extended high-end frequency response in a cardioid condenser design. The microphone adds warmth to the frequency response and creates an ideal environment for in ear personal monitoring. And its highly consistent cardioid pattern offers excellent rear rejection.
