AKGC151 C-Series Small-Diaphragm Condenser Microphone

Product overview
About this model
When accuracy and articulation matter most, the AKG C151 delivers crisp, vibrant sound with confident control. Designed for podcasters, streamers, YouTubers and musicians alike, this small-diaphragm cardioid condenser microphone brings AKG’s studio engineering heritage into a compact, modern form. Its fast transient response, 20Hz–20kHz frequency response, focused pickup pattern and transformerless FET circuitry make it an excellent choice for capturing instruments, voice and content with clarity that feels immediate and natural. Custom Small-Diaphragm Capsule With Cardioid Focus At the heart of the C151 is a custom-engineered 16 mm small-diaphragm capsule designed to reproduce sound with exceptional accuracy and speed. This design excels with transient-rich sources such as acoustic guitar, percussion, strings and detailed speech, capturing nuance without smearing or unwanted coloration. The fixed cardioid polar pattern maintains focus on the primary source while reducing room reflections and off-axis noise, making the C151 especially effective in home studios, broadcast setups and close-miking applications. High Headroom and Ultra-Wide Dynamic Range Built for demanding performance environments, the C151 handles sound-pressure levels up to 147dB with minimal distortion, allowing it to capture everything from loud amplifiers and percussion to delicate string passages with equal confidence. Its transformerless FET circuit maintains a low noise floor and wide dynamic range, preserving subtle detail at lower levels while remaining clean and controlled at higher volumes. The result is articulate, detailed recordings that translate smoothly into mixes without relying on corrective processing. Sustainably Designed for the Future of Audio The C151 is engineered with sustainability as a core principle, featuring a microphone body crafted from 100% recycled PIR metals and alloys. Accessories and packaging are designed to minimize environmental impact and are fully recyclable, while still meeting professional durability expectations. It’s a thoughtful, forward-looking design that balances AKG’s sound-quality standards with a responsible manufacturing approach.
