Blumlein Stereo Microphone Technique

In this video I give a demonstration on how to capture a stereo recording of a piano using two condenser microphones in the Blumlein array. I use two Rode NT2A microphones for the stereo technique plus a Rode NT 4 as a room mic plus a Sennheisser e906 close in on the harp. You might notice that the NT2A's are facing the wrong way (negative side of capsules facing the sound source) offering a brighter sound capture. Both mic's were phase inverted on the input channels to match the electrical polarity of the other microphones in the mix.
