Exceptionally Consistent Mic Capsule
Designed for the A20-HH handheld microphone, the Sound Devices CD1 sets a new standard for consistency in a dynamic mic capsule. Every CD1 mic capsule is 100% swept and calibrated at the Sound Devices factory, meaning that each CD1 matches the overall sensitivity and vocal-friendly frequency response of every other CD1 ever made! This incredible consistency in a dynamic microphone capsule is unheard of and has thoroughly impressed our Sweetwater live sound engineers. The Sound Devices CD1 also sports a patented dual-engine design with two voice coils and two diaphragms. This design gives you similarly consistent polar patterns, very low handling noise, and superb dynamic range greater than 140dB. Finally, the Sound Devices CD1, with its steel grille, internal shockmount, and overall durable construction, ships to you tour-ready right from the get-go.
