Usually arrives in 5-9 business days.
Sound installations and working bands need powerful wireless tools that can be set up quickly and used confidently. Shure's rugged SLX Wireless Systems exceed these demands with innovative setup features such as auto frequency scan with transmitter setup, exceptional wireless clarity, and legendary Shure microphones.
SLX Wireless Systems feature the Shure patented Audio Reference Companding for clear sound beyond the limits of conventional wireless technology.
The SLX Wireless Systems feature a wide variety of industry-standard handheld vocal microphones. SLX Wireless Handheld Transmitters includes timed backlit LCD display, frequency and power lockout, and "Mute" functionality.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 SLX Wireless systems.
The SLX4 receiver brings unprecedented ease of use to wireless with Automatic Frequency Selection and Automatic Transmitter Setup. For use with SLX Wireless. With included rack hardware and detachable antennas, it is ready for immediate installation right out of the box. Model SLX4L is available with logic output for use with software echo cancellation and remote battery life monitoring. Logic-enabled transmitters include MX690 and MX890.
The Shure SM86 is a unidirectional (cardioid) condenser vocal microphone for professional use in live performance. An extremely rugged microphone, the SM86 withstands the rigors of touring while delivering a clear, studio-quality sound.
A cardioid pickup pattern isolates the main sound source while minimizing unwanted background noise. The built-in three-point shock mount minimizes handling noise, and a two-stage pop filter reduces wind and breath "pop" noise.
Note: When purchasing separate wireless components, please match their frequency bands to ensure proper system operation.
