Shure BLX14R/W85 Wireless Lavalier Microphone System

Shure BLX® Wireless Systems provides a great option for freeing up your hands and making yourself mobile while speaking. Enjoyed by public speakers, worship leaders and community theater groups, this lavalier system generates big sound with a low-profile presentation. The lavalier microphone’s cardioid design brings focus to your voice while minimizing other sounds. Simply clip the bodypack transmitter onto a belt, clip the lavalier mic to your top, and you can move up to 300 feet away (within line of sight) from the receiver.

The Shure BLX14R/W85 lavalier wireless system provides professional sound quality with simple setup and an intuitive interface, offering legendary audio performance right out of the box. Setup is a breeze with the one-touch QuickScan frequency selection that quickly determines the best frequency for you. LED indicators note the status of different operations such as the strength of incoming audio on the receiver and battery charge level on the transmitter. Bodypack transmitter can last for up to 14 hours of continuous use with the batteries provided.

Analogue wireless transmission communicates between the BLX4R rack mount wireless receiver and the BLX1 bodypack transmitter. Sound quality will be best when the bodypack transmitter is at least 16 feet from the receiver. Gain can be adjusted with a rotating dial directly on the bodypack transmitter.

This wireless receiver has more flexibility to create your ideal sound balance than other receivers in the Shure BLX series. Output level can be adjusted, and an LCD display screen shows detailed RF and audio metering. Rack mount hardware is included for the receiver, which also boasts removable antennas for quick distribution.
