Audio-Technica AT4060A Cardioid Condenser Tube Microphone

The Audio-Technica AT4060a cardioid vacuum tube condenser microphone is a technological marvel, designed to bring the warmth and richness of vintage tube sound to a variety of modern studio applications. Created with hand-selected, individually tested, and aged tubes, this microphone captures the subtleties of vocal and instrumental performances with unparalleled clarity. Whether you're recording in high sound pressure level (SPL) environments or capturing the minute nuances of delicate audio, the AT4060A stands out by exceeding the dynamic range of most tube microphones on the market. Employing a dual-diaphragm capsule design, this microphone ensures precise polar pattern definition across its entire frequency range, making it an indispensable tool for demanding recording situations.

Engineered with a 2-micron-thick, vapor-deposited gold diaphragm, the microphone undergoes a rigorous five-step aging process to retain its optimum characteristics over the years. This makes the AT4060A not just a microphone, but an investment in lasting quality. The precision-machined, nickel-plated brass acoustic element baffle guarantees enhanced element stability and optimal sensitivity, while the heavily filtered heater current and large coupling transformer contribute to superior low-frequency linearity and overall sound isolation. The included custom shock mount further elevates the microphone's performance by providing superior isolation, ensuring that your recordings are free from unwanted noise.
