Details

A choice of legendary Shure vocal microphones is available for use with the ULX Professional series of handheld wireless transmitters.  Choose from SM and BETA Series microphones to ride the clear channel transmission and flexibility of ULX handheld transmitters.

The transmitter design allows for interchangeable microphone cartridges. Options include the BETA 87A, BETA 87C, BETA 58A, SM86, and the legendary SM58. For use with ULX Professional Wireless systems.

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.
