The Audio-Technica AT4080 Bidirectional Ribbon Microphone delivers the classic warm and smooth sound of a ribbon microphone while addressing historical limitations regarding fragility and low output. This handcrafted microphone utilizes six new patents to advance ribbon transducer design, making it suitable for both recording studios and live-sound settings.
The AT4080 features the innovative MicroLinear™ ribbon imprint, which protects the dual ribbons from lateral flexing and distortion to ensure long-lasting performance. This dual ribbon construction increases sensitivity, while extremely powerful N50 rare earth magnets provide a high output level. The microphone utilizes phantom-powered active electronics to maintain stable impedance and ensure maximum compatibility with various microphone preamplifiers.
The bidirectional (figure-of-eight) polar pattern captures sound equally from the front and back of the element. An acoustic baffle system combined with an extra-large output transformer provides a natural low-frequency response and extended dynamic range. High-SPL capability and an extended frequency response allow for natural audio reproduction across professional recording, broadcast, and sound reinforcement applications.
Every AT4080 undergoes a handmade production process, including ribbon corrugation, imprint, and assembly. The housing assembly features an open acoustical environment to minimize unwanted internal reflections and maintain high-fidelity sound. For added protection, an ultra-fine mesh guards the ribbon against damage. This microphone is certified by the METAlliance (Music Engineering and Technology Alliance) and includes a custom shock mount for superior isolation.
