Designed to capture the balanced, detailed acoustics of the beloved original ’47 FET-style microphone, Warm Audio offers the WA-47F large diaphragm FET condenser microphone, with much greater accessibility. With universal application of studio, home or live use, the versatility of this mic lends itself to any situation without comprising on sound quality. Paying homage to its predecessor, the sonic character of this mic gives a wide dynamic range with a detailed bass and pristine high end that you’re looking for, at a value that cannot be beaten.

Custom Reproduction Gives Pristine Sound

The gold sputtered, single backplate, large diaphragm WA-47-B-50v capsule, is a premium reproduction of the vintage K47 capsule to bring you that detailed, authentic ’47 FET sonic character. This capsule produces a wide frequency response of 20Hz–19kHz with a rise in the midrange and a smooth high-end for an added depth. To further supply a rounded and smooth sound, is the TAB (AMI) transformer, made in the USA but with German laminations that help to capture a true analog sound with plenty of coloration. The Fairchild FET transistors along with the WIMA and polystyrene capacitors that this mic has gives a strong signal conversion for excellent reliability.

Vintage Acoustics With Accessible Features

The 140Hz low-cut filter helps to further minimize unwanted bass noise, which is ideal for sources such as electric guitar cabs. There is also a -10dB pad that provides extra headroom for your really loud sources while still maintaining sonic detail. This mic has a cardioid polar pattern that delivers a wide dynamic range and detailed bass response, making it perfect for vocals and kick drums. With a bright top end and a rich low end, the WA-47F is a compelling option for anyone looking for that classic ’47 FET sound.
