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
