The Shure BLX Wireless Systems combine professional-quality sound with simple setup and an intuitive interface for legendary audio performance right out of the box. Precision-built and available in a variety of configurations, it’s the most accessible way to own the stage.
Rack-mountable and featuring rugged metal construction, the BLX4R offers simple setup and intuitive controls. One-touch QuickScan frequency selection quickly locates the best open frequency in case of interference. Removable antennas allow for quick antenna distribution.
The durable BLX1 features a lightweight, ergonomic design and adjustable gain control. It comes equipped with power and battery status LED, 2 AA batteries that provide up to 14 hours of continuous use and has an operating range (line of sight) of 300 ft (91 m). (Note: When purchasing separate wireless components, please match their frequency bands to ensure proper system operation).
WL185 is a lavalier electret condenser mic designed for use with a wireless body-pack transmitter. It has a 4 ft (1.2 m) cable terminated with a miniature 4-pin mini connector. The included tie clip can be rotated in 90 degree intervals for placement flexibility. It features CommShield Technology, which guards against interference from cellular RF devices and digital bodypack transmitters. It is recommended for general purpose sound reinforcement applications requiring good rejection of ambient noise. It has a pickup angle of 130 degrees and use of the windscreen is highly recommended.
