This site features projects and circuits for building stereo microphones from low-cost Panasonic electret microphone capsules. Included are Mid-Side, XY, and Blumlein microphone setups. In addition, there are interesting related circuits and links to sites with microphone information and parts sources.


MS Mic Version 2
This mic uses two Panasonic WM-55A103 cardioid electret capsules whose outputs are combined to form a figure eight mic for the side output, and a front-firing electret for the mid output. It has a stereo matrixing cicuit with adjustable width and a built-in preamp with adjustable gain providing a line level unbalanced output.

Phantom Powered XY Mic
This mic uses two Panasonic WM-55A103 cardioid electret capsules in XY configuration. A simple four transistor circuit uses phantom power to power the capsules and provide balanced microphone level low impedance outputs.
