AKG C151 Small-Diaphragm Cardioid Condenser Microphone

The AKG C151 is a professional small-diaphragm condenser microphone designed for accurately capturing musical instruments, performances and ambient sound. Its compact design, wide frequency response and focused cardioid pickup pattern make it suitable for studio recording, live sound, broadcasting, podcasting and content creation.

The microphone features a precision 16 mm electret condenser diaphragm that captures fine detail with a clear and natural tonal response. Its cardioid polar pattern focuses on sound directly in front of the microphone while reducing unwanted sound from the sides and rear.

An optimised transformerless FET circuit provides reliable performance, a broad dynamic range and a low noise floor. With a maximum sound pressure level of 143 dB, the C151 can handle loud sound sources such as drums, percussion, brass instruments and guitar amplifiers.

The C151 operates using standard 48V phantom power and connects through a professional 3-pin XLR output. Its slim, lightweight body makes it easy to position around instruments and recording setups.

The microphone body is manufactured from 100% recycled post-industrial recycled metals and alloys, while the packaging and accessories have been designed to reduce environmental impact.
