With the groundbreaking AT4080, Audio-Technica achieves the coveted ribbon microphone sound while solving the problems of fragility and low output that have historically plagued ribbon mics. Delivering the warm, smooth sound of a classic ribbon microphone, Audio-Technica's handcrafted AT4080 Active Ribbon Microphone offers a robust build for long-lasting, reliable performance and higher output for maximum compatibility with microphone preamplifiers. Equally at home in recording studios and in 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 innovatibe ribbon transducer advances the evolution of ribbon microphone design. Experience the difference.
Folded, embossed and hand-assembled, the MicroLinear ™ ribbon is a patented process. The ribbon of the AT4080 and its junction plates are coated with a thin gold film which prevents corrosion without interfering with the mass or the resonant frequency of the ribbon, while conventional ribbon microphones use a sheet of pure aluminum, susceptible to corrosion by moisture in the air.
Unlike the techniques usually employed by microphone manufacturers, about 80% of the integrated ribbon in the AT4080 is vertically corrugated over the length of the microphone. Only the ends of the ribbon are corrugated horizontally, which provides a more rigid ribbon, thus avoiding the risks of distortion associated with a high sound pressure level (the AT4080 is capable of 150dB SPL, 1kHz 1% THD ).
While the use of phantom power was excluded for previous ribbon microphones, the AT4080 requires 48V phantom power for operation. Phantom power is not used for the bidirectional active ribbon microphone, but for its active electronics, providing a near equivalent level to the output of a condenser microphone. The extremely powerful N50 Neodymium magnets integrated into the AT4080 provide a high output level, and its stable impedance facilitate the integration of this microphone into all types of preamplifiers. The output circuit is transformerless, using a 3-pin XLR connector.
