What is a Differoid?

Explain "Differoid" to me please. Is it referring to the polar pattern?
Thanks, 
Chris M.

Reply:
Differoid is short for Differential Cardioid. "Differential" means that the mic works on the difference in sound pressure betwen the front and rear of the mic diaphragm. Such a mic is noise cancelling, so it rejects sound at a distance (such as guitar amps or drums on stage and PA speakers). "Cardioid" means that the mic rejects sound arriving from behind the microphone , such as floor monitors.

By rejecting distant sounds and rear-arriving sounds, the Differoid provides outstanding gain -before-feedback and isolation. For more information, click the link below.
