Description

Edit description

For performers who crave freedom of movement without sacrificing sound quality, the Crown CM311 Headworn Condenser Mic is a perfect companion. This headworn microphone gives you hands-free clarity, allowing you to focus on your performance rather than mic handling. It's not just about convenience, though; it's designed for high-quality sound reproduction, rivaling the best handheld microphones.

The CM311 shines when it comes to combating feedback and ambient noise. Its Differoid technology - differential cardioid pickup pattern - effectively cancels out unwanted sounds from floor monitors, crowds, and other sources. This means you can expect a cleaner, clearer house mix. Plus, its noise-canceling capability delivers an impressively high gain before feedback, ensuring your voice is always front and center.

Designed for touring and live-sound applications, the CM311 is robust and ready to hit the road. It's compatible with TA4F connectors, making it ideal for use with Shure Wireless Systems.

Key Features:

Hands-free, headworn design
Differoid technology for effective noise cancellation
High gain before feedback
Excellent sound quality, comparable to handheld microphones
Compatible with TA4F connectors for use with Shure Wireless Systems
Ideal for touring and live-sound applications
