Shure BLX14R/W93 Wireless Lavalier Microphone System

Shure BLX® rack-mount presenter system provides a sound solution to free up your hands and make yourself mobile while speaking. Microphone headset connects to the bodypack transmitter, which can operate up to 300 feet away (line of sight) from the receiver. Professional quality and simple setup with an intuitive interface come together to create legendary audio performance right out of the box. These features and more make this wireless system a good choice in theatres, lecture halls, television and movie sets.

The Shure BLX14R/WL93 wireless microphone system communicates between the BLX4R receiver and the BLX1 bodypack transmitter. Rack mount receiver fits neatly into an existing setup or on its own. QuickScan frequency selection finds the best available frequency for the receiver and transmitter with just one touch at setup. In addition to fast frequency selection, this analog receiver delivers improved linearity and frequency response. LED indicators on the receiver display the status of audio levels so gain can be adjusted as needed. The rack mount kit is included, and the antennas are removable for quick antenna distribution.

Paired to the receiver is the BLX1 bodypack transmitter. Worn on a belt, this bodypack transmitter is lightweight and will go unnoticed by audiences and performers alike. With a battery life of up to 14 hours and an LED indicator for low battery level, this wireless system lasts through even long uses. Functions such as group and channel selection and gain adjustment can be done right from the bodypack transmitter. The on/off switch is easily accessible and uses a toggle design, providing tactile indication when the transmitter is on.

Miniature lavalier microphone WL93 provides the full clear sound desired in speaking applications where this system is used. Using an omnidirectional polar pattern, this lav mic is sensitive to sound coming from all directions, offering rounded full sound. In addition to its sound pattern the mic is visually unobtrusive, making it well-suited for theater and broadcast applications. Smooth extended frequency response and controlled low-frequency rolloff minimize unwanted sound, particularly in chest-worn mic operation.
