Stereophonic Microphone Technique
Classic Blumlein Technique
For many years, several “coincident” microphone setups have
been widely used for picking up sounds in stereo as naturally as
possible.
The “Blumlein” technique, named for A.D. Blumlein of England,
involves the use of two figure-eight microphones positioned as
in the sketch (see Figure 1), so that one faces left and the other
right, at an angle of 90º (i.e. each displaced 45º from center).
Each microphone ultimately feeds one speaker in a stereo system,
and due to the directionality of the microphones, the result is a
very well defined stereo effect on playback. For classical music,
particularly, the reproduction can be very satisfying.
