AT4081 Phantom-powered Bidirectional Ribbon Microphone

Delivering the warmth and natural sound of a classic ribbon microphone, Audio-Technica’s handcrafted AT4081 offers a robust build for long-lasting performance and higher output for maximum compatibility with microphone preamplifiers. With its low-profile stick design, this microphone is a natural for use on a wide range of instruments (horns, strings, drum overheads, orchestras and more) and guitar cabinets in recording studios and live-sound settings.

Equally at home in recording studios and live-sound settings, the microphone features Audio-Technica’s innovative MicroLinear™ ribbon imprint, which protects the dual ribbons from lateral flexing and distortion. With 18 patents pending, Audio-Technica’s innovative ribbon transducer advances the evolution of ribbon microphone design. Experience the difference.
