Cardioid Tube Condenser Microphone

The AT4060 is a cardioid tube condenser microphone with a transformer-coupled output circuit.

The tube is reportedly a hand-selected 6922 Sovtek.

The mic’s capsule, although described as a large diaphragm design, has a 21.4mm active diameter. The membrane material is 2 microns thick.

AT4060 CutawayThis capsule is visually identical to the capsules found in the two AT4047 models, the AT4050 and AT4060ST. All use a center-terminated 21.4mm-diameter capsule covered by a perforated metal acoustic baffle. In some models, such as the AT4060, this capsule is surrounded (or partially surrounded) by a perforated metal frame.

  • Cardioid vacuum tube condenser
  • High dynamic range (131 dB) and maximum SPL (150 dB)
  • hand-selected, individually tested and aged tubes
  • every AT4060 is individually tested and inspected for 100 percent quality assurance
  • 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
  • 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
  • Regulated and heavily filtered heater current prevents noise contamination of audio signal chain
  • Hand-selected tubes are individually tested and aged to maintain peak performance
  • Large coupling transformer provides superior low-frequency linearity
  • Custom shock mount provides superior isolation

The AT4060 ships with its tube power supply (Audio-Technica part number AT8560), shockmount (p/n AT8447), and a carrying case.


The mic was great for vocals, providing a full midrange that was neither thin nor muddy and which cut right through the mix. It also performed quite well on acoustic guitar, capturing the instrument’s full, low-end body as well as its higher frequencies, and it was superb for clean electric guitar sounds and solos, picking up the brighter frequencies and delivering a clear, ringing tone.

The AT4060 was replaced by the AT4060A in 2014.

The Audio-Technica AT4060 is also known as: AT-4060.
