Description This system includes: SLX2 Handheld Transmitter w/SM58 cartridge, SLX4 Diversity Receiver, WL185 Lapel microphone and SLX1 Bodypack transmitter. Either the Handheld transmitter or the Lapel/Bodypack can be used, but not both at the same time . 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. This system includes the SM58 cardioid cartridge. The SLX1 bodypack transmitter is designed to hold up to the most adverse conditions. Whether used with headworn, lavalier, instrument microphones, or with guitars or basses, the SLX1 is the definition of reliability WL185 (Cardioid): Recommended for general purpose sound reinforcement applications requiring good rejection of ambient noise. Use of windscreen highly recommended. Pickup angle is 130 degrees Specifications: Operating Range Under Typical Conditions 100m (300 ft.)
