Large-Diaphragm Multi-Pattern Condenser Microphone with Windscreen, Shock Mount and Case


the best-kept secret for thin vocals and instruments

The C4000 is a high-performance multipattern large-diaphragm microphone with exceptionally high headroom and extremely low self-noise. It is among the condenser microphones with the widest dynamic range available today, and it will give equally excellent results in the studio and on stage.

Due to its warm and dark-sounding character, it is known in the pro-audio world as an insider's tip for thin vocals, bright brass instruments and acoustic guitars. Beyond that, it is designed for miking a broad range of instruments from electric guitar to kick drum.
