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.
The BLX14/B98 includes BLX4 single-channel receiver, BLX1 bodypack transmitter, BETA 98H/C instrument microphone, power supply, 2 AA batteries, carrying case, and user guide.
The BLX4 Single Channel Receiver features simple setup, intuitive controls, and microprocessor-controlled internal antenna diversity. It includes 1/4" and XLR audio outputs and two-color audio status indicator LED. One-touch QuickScan frequency selection quickly locates the best open frequency in case of interference.
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 BETA 98H/C is a premium cardioid condenser instrument microphone that clamps onto the bell of wind instruments or onto the rim of percussion instruments. The integrated gooseneck and ratcheting swivel joint allows the mic to be easily positioned and secured, and an isolation shock-mount reduces the transmission of instrument 'key noise' and other mechanical noise. A gooseneck angle brace is included to provide better retention of the microphone placement during more active performances.
Note: When purchasing separate wireless components, please match their frequency bands to ensure proper system operation.
