This microphone has an excellent vintage tube sound with the versatile performance necessary for the most demanding studio applications. The precision-machined, nickel-plated brass, acoustic element baffle provides enhanced element stability and optimal sensitivity, while the 2-micron-thick, vapor-deposited gold diaphragms undergoes a five-step aging process so that the optimum characteristics achieved remain constant over years of use. A dual-diaphragm capsule design maintains precise polar pattern definition across the full frequency range of the microphoneWide dynamic range, low self-noise and high max SPL capabilityRegulated and heavily filtered heater current prevents noise contamination of audio signal chainHand-selected tubes are individually tested and aged to maintain peak performanceLarge coupling transformer provides superior low-frequency linearityAccessories Furnished: AT8560 power supply, switchable 120V/230V input; AT8447 shock mount; 32.8' (10 m) special mic-to-power supply cable; AC power supply cable; power supply rack-mount adapters; protective mic case
