AKG CM311 XLR - Headset Condenser Microphone with Cardioid Polar Pattern and 50Hz to 17kHz Frequency Response in Black Finish

The AKG CM311 XLR Headset Condenser Microphone is a top-tier, head-worn microphone designed specifically for touring and live sound applications, where high-performance audio capture is essential. Offering a cardioid polar pattern and utilizing AKG's Differoid technology, this microphone provides an exceptional level of isolation and sound clarity. The Differoid system features a differential cardioid design, which significantly reduces ambient noise from sources such as floor monitors, crowds, and other environmental distractions. This unique technology gives the CM311 a remarkable advantage over traditional cardioid microphones, offering up to 12dB more gain before feedback. As a result, the CM311 ensures that the user's voice or instrument is captured with maximum clarity, even in loud, live performance environments.

Engineered to perform like the best handheld microphones, the CM311 delivers a full, clear, and distortion-free sound, even when used by the loudest singers. This makes it an excellent choice for vocalists, musicians, and presenters who require high-quality audio in demanding conditions. The cardioid pickup pattern of the microphone focuses on the sound directly in front of the user while effectively rejecting sound from the sides and rear, further enhancing isolation and minimizing unwanted noise.

The CM311 is designed with flexibility in mind. It features a robust XLR output for reliable, high-quality connectivity to sound systems and wireless transmitters, making it adaptable to a wide range of audio setups. The microphone also supports a voltage range of 18 to 48 V, providing the necessary phantom power for professional-grade sound capture. It comes with a carrying case for easy storage and portability, as well as a WS-6 foam pop filter to reduce wind and plosive noise, ensuring that every word or note is captured clearly without interference.

Lightweight and comfortable, the CM311 is designed for long-duration wear, with a net weight of just 0.13 lbs. Its satin black finish ensures a sleek, professional appearance, making it suitable for use in any live sound or touring environment. Whether you're performing on stage, delivering a keynote address, or broadcasting live, the AKG CM311 XLR headset microphone offers the reliability, performance, and isolation needed to deliver pristine audio, even in the most challenging environments.
