Product Description
The Crown CM311A/SH is the industry-standard headworn condenser microphone designed for professional touring, live sound, worship, theater, and presentation applications. Renowned for its exceptional vocal clarity and advanced Differoid® technology, the CM311A/SH delivers superior gain before feedback while effectively rejecting ambient stage noise and monitor bleed.
Unlike conventional headset microphones, the CM311A/SH captures vocals with the full, natural sound quality of a premium handheld microphone. Its unique differential cardioid design isolates the performer’s voice from surrounding noise sources, making it a preferred choice for vocalists, speakers, drummers, worship leaders, and performers working in high-volume environments.
Controlled field tests have demonstrated that Crown's Differoid technology can provide up to 12 dB more gain before feedback than traditional cardioid microphones, resulting in cleaner mixes and improved vocal intelligibility.
