The CVL Microphone
Combining durability and quality, the CVL Lavalier Condenser Microphone is ideal for applications where your mic needs to be heard but not seen. This miniature lav comes with a tie clip for easy positioning that frees up your hands, while its low-profile design ensures your audience focuses on your performance, and not your gear. A built-in TA4F (TQG) connector allows this mic to seamlessly integrate into myriad Shure wireless systems. The CVL Centraverse lavalier condenser microphone is built for low visibility and clear vocal reproduction. The mic features a cardioid polar pattern that rejects unwanted noise, Commshield RF Filtering to minimize RF interference from nearby smartphones, and a tailored frequency response optimized for speech intelligibility.
Versatile and expandable
A choice of single-channel, single-channel half-rack, and dual-channel receivers, as well as vocal, guitar, headset, and lavalier options, makes Shure’s BLX wireless systems quite versatile. And the ability to run up to 12 compatible systems per band protects your investment, letting you start out modestly and expand as necessary.
