Cardioid Condenser Tube Microphone


The rebirth of an audio-technica classic

  • Patenthe rebirth of an audio-technica classicted "Double Wave" Dual-diaphragm capsule design maintains precise polar pattern definition across the full frequency range of the microphone
  • Precision-machined, nickel-plated brass, acoustic element baffle provides enhanced element stability and optimal sensitivity
  • Large coupling transformer provides superior low-frequency linearity
  • Vintage tube sound with the versatile performance necessary for the most demanding studio applications
  • Hand-selected tubes are individually tested and aged to maintain peak performance
  • Regulated and heavily filtered heater current prevents noise contamination of audio signal chain
  • Wide dynamic range, low self-noise and high max SPL capability
  • The 2-micron-thick, vapor-deposited gold diaphragms undergo a five-step aging process so that the optimum characteristics achieved remain constant over years of use
  • Product designed and manufactured in Japan

    Audio-Technica AT4060a is a large-diaphragm cardioid condenser tube microphone, designed for use in the most demanding studio applications. Each hand-selected tube is individually aged and tested, then employed in a uniquely configured circuit for enhanced tube performance.

    Specially tuned elements improve dynamic range and the allow the AT4060a to handle high SPLs (up to 150dB) without sacrificing high-frequency characteristics. A floating-construction mounting of the elements provides isolation from noise and vibration.

    The AT4060a operates in conjunction with the included AT8560a tube microphone powering unit, featuring low-impedance output and a ground-lift switch.
