Microphone Placement

Stereo ORTF
To mount your M5 pair in ORTF confi guration, place the
microphones either on a stereo bar, or on two separate
microphone stands. The microphones should be placed at 110º to
one another with the capsules 17cm apart and facing outward.
The ORTF technique was devised around 1960 by a French
broadcast station, the Offi ce de Radiodiffusion Télévision
Française, and was originally designed to mimic the
response of human hearing.
The increased distance between the capsules will produce
a wider stereo image than coincident stereo miking
techniques like X/Y or Mid-side.
