AKG CM311 W/TA4F Reference Head-Worn Condenser Microphone

Designed for touring, live sound and security monitoring, the AKG by Harman CM311 head-worn condenser microphone delivers handheld-quality vocal clarity while keeping users hands-free. AKG’s Differoid differential cardioid technology provides up to 12 dB more gain before feedback than conventional cardioids, isolating performers and presenters from floor monitors, crowd noise and environmental sound—an advantage for live-sound engineers, AV integrators and surveillance teams. The electret condenser capsule with internal shock mount minimizes mechanical and body noise while preserving a wide frequency response (50 Hz–17 kHz) for natural, intelligible speech and accurate monitoring. Flexible power options (phantom or 9V battery) and a programmable belt-pack with mic on/off make the CM311 easy to deploy in wired PA systems, installed AV, portable setups and security monitoring stations. Its comfortable headband and durable construction ensure reliable performance during long events or continuous shifts. Backed by a 2-year limited warranty, the CM311 is a practical choice for pro audio, presentation, retail and security applications — add it to your AV or surveillance toolkit today or contact sales for integration support.
