The AT4060a is a cardioid condenser, valve, equipped with a large diaphragm, designed to be used in the most demanding studio applications. The valves that it incorporates have been selected by hand, tested and aged individually, and use a unique circuit that enhances the qualities and behavior of the valve. The specially adjusted elements improve the dynamic range and its ability to handle high SPL levels without sacrificing the characteristics of high frequencies. All its elements have been mounted in a floating way, providing a high level of insulation against noise and vibrations.

Classic valve sound, with the necessary versatility in the most demanding applications in modern studies The valves, selected by hand, are tested and aged individually The filament current is regulated and filtered to prevent contamination of the audio signal with undesirable noise Wide dynamic range, low intrinsic noise and maximum SPL handling capacity Large coupling transformer offering maximum linearity at low frequencies Double diaphragm design that maintains a precise polar pattern throughout the frequency spectrum Vaporized gold diaphragms, with a thickness 2 micron, and subjected to five aging processes The nickel-plated brass acoustic baffle element, with precision machining, provides greater element stability and optimum sensitivity The special design shock absorber provides maximum insulation
