WA-47 Tube Microphone

Tube Condenser Microphone with 9x Polar Patterns

The Warm Audio WA-47 Tube Condenser Microphone is an all-vacuum tube, large diaphragm condenser microphone featuring nine polar patterns and a 20Hz-20kHz frequency range. The WA-47 is designed for pro studio, home studio, live and broadcast applications for a range of instruments as well as vocals. The WA-47 utilises a custom reproduction of the vintage k47 style capsule that was used in the classic ‘47 microphone designed with the same hole pattern and frequency response.
A JJ 5751 vacuum tube is a lower gain, low-noise tube that forces much of the sonics of the capsule and transformer to be heard more significantly than some higher gain tubes might allow. The frequency response of the JJ 5751 and the way it contributes to the circuit is tonally smooth and vintage in nature. The WA-47 contains a TAB-Funkenwerk (AMI) USA transformer with large core imported German laminations. This transformer helps provide the creamy smooth top end, and the bottom end one would expect from a '47 style condenser microphone.
