Part of the Shure SLX wireless systems family, the SLX24/BETA87A system consists of a SLX2/BETA87A Handheld Wireless Microphone/Transmitter and SLX4 Diversity Receiver.

Sound installations and working bands need powerful wireless tools that can be set up quickly and used confidently. Shure's rugged SLX UHF Wireless Systems exceed these demands with innovative automatic setup features, such as auto frequency scan and transmitter setup, exceptional wireless clarity, and legendary Shure microphones. Supporting 20 compatible systems across multiple UHF frequency bands, SLX smoothly integrates into houses of worship, lecture halls, conference rooms, and mobile gear cases.

The SLX4 receiver brings unprecedented ease of use to wireless with Automatic Frequency Selection and Automatic Transmitter Setup. With included rack hardware and detachable antennas, it is ready for immediate installation right out of the box.

The SLX2 Wireless Transmitter features a wide variety of industry-standard handheld vocal microphones. Options include the Beta 87A or C, Beta 58A, SM86, and the legendary SM58.

The Shure Model Beta 87A is a premium quality supercardioid hand-held electret condenser vocal microphone with exceptionally smooth frequency response and high sound pressure level (SPL) 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.
