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).
The Microflex MX153 provides outstanding clarity in an extremely comfortable over-the-ear design. This professional subminiature ear set microphone is ideal for applications in which improved gain before feedback over lavalier microphones is desired. Delivering exceptional speech clarity, the MX153 is ideal for corporate presentations, houses of worship, A/V conferencing, and live sound reinforcement.
Note: When purchasing separate wireless components, please match their frequency bands to ensure proper system operation.
