The CD1 Mic Capsule from Sound Devices is a high-performance modular capsule designed for the A20-HH handheld microphone/transmitter, offering outstanding consistency and reliability for professional vocal applications. As the world's only 100% calibrated dynamic mic, every CD1 is factory-tested to ensure identical sensitivity and frequency response across all units delivering uniform sound, session after session.
Engineered for superior vocal clarity, the CD1 features a cardioid polar pattern with a well-balanced 50 Hz to 15 kHz frequency response tailored specifically for voice reproduction. Its patented dual-engine design incorporating two voice coils and two diaphragms ensures consistent polar patterns across all frequencies, reduces handling noise, and maximizes dynamic range with a >140 dB SPL handling capability.
Despite its advanced acoustic engineering, the CD1 is built for the demands of touring and live performance. The capsule's rugged construction, integrated shock-mounting, and durable steel grille provide exceptional durability, ensuring flawless operation, even after repeated drops and handling.
