Description

Details

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.

The Shure Beta 87A is a premium quality supercardioid hand-held electret condenser vocal microphone with exceptionally smooth frequency response and high sound pressure level capability. Used for professional sound reinforcement, broadcasting, and studio recording applications, the Beta 87A combines superb performance with the ruggedness needed for touring and field production.

The Beta 87A features a controlled low-frequency roll-off that compensates for proximity effect and prevents the “boomy” sound often associated with close pick-up. The characteristic Shure presence rise brightens the upper midrange. The tight supercardioid pattern, with null points at approximately 125 degrees, provides maximum isolation from other vocalists or instruments while offering minimal off-axis coloration. The Beta 87A operates on phantom power.

For use with SLX Wireless Systems only.

Note: When purchasing separate wireless components, please match their frequency bands to ensure proper system operation.
