Product Details

Shure ULXP124/87 Dual Channel Mixed Wireless System

The Shure ULXP124/87 Dual Channel Mixed Wireless System includes two ULXP4 Diversity Receivers, a ULX1 Bodypack Transmitter, and a ULX2 Handheld transmitter fitted with an SM87A microphone capsule. 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.

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.

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.
