A New AKG Standard in the Small-Diaphragm Family
The C151 continues the legacy of AKG studio microphones by combining the classic inspiration of the "C" series with modern engineering. Its 16 mm electret capsule and transformerless FET circuitry extend the brand's expertise in precision and reliability while adopting a sustainable design approach.
Who Is It For and What Are Its Uses?
Ideal for content creators, podcasters, streamers, and videographers, the C151 also excels at instrument recording: electric guitars, strings, percussion, overheads, and acoustic ensembles. Its cardioid pattern isolates the source and reduces bleed, making it a relevant choice for home studios, webcasting, or light broadcast.
Key Features for Clear and Modern Recordings
Detailed capture and room control: The small-diaphragm capsule offers fast transient response and a coherent sound image. The cardioid pattern favors the source and limits ambient noise.
Generous headroom: With 147 dB SPL at 0.5% THD, the C151 handles the most demanding sources effortlessly, from saturated amps to percussion, while maintaining a clean and usable sound for mixing.
Studio and streaming ready: Its low self-noise and sensitivity of 11 mV/Pa (-39 dBV) ensure an excellent signal-to-noise ratio. Powered by 48V phantom power, it integrates instantly with any standard audio interface or console via XLR.
Responsible design: 100% recycled metal body, accessories designed for durability, and low-impact packaging for professional equipment aligned with eco-friendly practices.
