At its core, the C151 features a custom engineered small diaphragm capsule paired with a transformerless FET circuit. This combination delivers exceptional clarity and accuracy, making it especially well suited to transient rich sources such as acoustic instruments, percussion, and detailed speech. The cardioid polar pattern focuses on the sound source while reducing unwanted room noise, helping you achieve clear, controlled recordings in a wide range of environments.

With an ultra wide dynamic range and very low noise floor, the C151 captures everything from subtle string detail to louder sound sources with confidence. High headroom allows it to handle sound pressure levels up to 147 dB without audible distortion, ensuring clean, detailed recordings across many applications.
