Shure BLX188/CVL Dual Wireless Lavalier Microphone System

Shure BLX® Wireless Systems provide 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 or guitar strap, 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 BLX188/CVL wireless dual presenter 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 transmitters. Bodypack transmitters can last for up to 14 hours of continuous use with the batteries provided.

This dual presenter system communicates using analogue wireless transmission between the BLX88 dual channel receiver and the two BLX1 bodypack transmitters. Sound quality will be best when transmitters are at least 6 feet from each other and over 16 feet from the receiver. Gain can be adjusted with a rotating dial directly on the bodypack transmitter.
