The 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 without sacrificing high-frequency characteristics.

Floating-construction mounting of the elements provides isolation from noise and vibration.


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


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

Large coupling transformer provides superior low-frequency linearity

Dual-diaphragm capsule design maintains precise polar pattern definition across the full frequency range of the microphone

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

Precision-machined, nickel-plated brass, acoustic element baffle provides enhanced element stability and optimal sensitivity
