Product Details
Shure ULXP24D/87 Dual Handheld Wireless Microphone System
The Shure ULXP24D/87 Dual Handheld Wireless Microphone System includes two ULXP4 Diversity Receivers, and two ULX2 Handheld Transmitters fitted with 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.
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.
SM87A Vocal Microphone
The Shure SM87A microphone is a professional-quality, handheld condenser microphone for use in sound reinforcement, broadcasting, and studio recording installations. Its supercardioid polar pattern provides greater rejection of unwanted sound sources, making it ideal for miking individual instruments in a multi-microphone setting or for miking single sources in a reverberant or noisy environment. An integral three-stage wind and pop filter protects against wind and breath noise. Its built-in shock mount reduces stand and handling noise.
