Audio Technica AT4060A Condenser Tube Microphone

Audio-Technica’s AT4060a cardioid vacuum tube condenser brings the warmth of vintage tube sound to every shade of the SPL spectrum. With a dynamic range that far exceeds that of other tube microphones, it as easily captures the subtlest nuances of vocal and instrumental performance as it handles guitar cabinets and other extreme SPL environments. Featuring hand-selected, individually tested and aged tubes, the AT4060a achieves the coveted, classic sound of valve design without compromising the specification standards required for the most demanding recording situations.

Audio-Technica takes no chances with this microphone’s consistency and reliability: every AT4060a is individually tested and inspected for 100 percent quality assurance—rare in today’s world of mass-marketed studio microphones.
