Shure BLX14R/W85 Lavalier Wireless System (Discontinued)
Usually arrives in 5-9 business days.
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. (Note: When purchasing separate wireless components, please match their frequency bands to ensure proper system operation).
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).
Model WL93 Microphones are economical omnidirectional, subminiature, lavalier, condenser microphones designed for general speech applications where a visually unobtrusive microphone is desirable. All WL93 models are supplied with a mounting block with attached tie bar, a sew-on mounting bracket, and an acoustic windscreen to minimize wind noise in outdoor applications. They also include a cable terminated with a 4-pin mini connector which connects directly to a Shure wireless body-pack transmitter.
Note: When purchasing separate wireless components, please match their frequency bands to ensure proper system operation.
