More about the CVL Microphone

Combining durability and quality, the CVL is ideal when your mic needs to be heard but not seen. A built-in TA4F (TQG) connector allows this mic to seamlessly integrate into myriad Shure wireless systems.

More about the BLX1 Bodypack Transmitter

The lightweight yet rugged build of the BLX1 means you don’t have to worry about damage during everyday use, and it easily clips onto a belt, pocket, or guitar strap for optimal placement.

A TQG connection on this transmitter enables connection with lavalier, headset, earset, and instrument mics, as well as guitar cables.

Turn the transmitter on and off and control your gain with controls on the bodypack itself. Its group and channel selection buttons enable quick frequency matching with the receiver.

More about the BLX4 Wireless Receiver

Typically paired with Shure lavaliers, headsets, or instrumental mics, the BLX4 can expand to up to 12 mic channels, making it a great choice to start and grow your sound system.

Setup is quick and easy with QuickScan frequency selection, which also provides improved linearity and frequency response.

The BLX4’s microprocessor-controlled internal antenna diversity reduces dropouts, while built-in 1/4" and XLR outputs enable connection to PA systems and mixing boards.
