Description / Abstract:

This Standard deals with connections and methods of testing which will result in correct phasing of microphones for use in broadcasting, recording, and sound reinforcement. It is well: .known that correct phase may be important to the operation of any system employing, simultaneously, more than one microphone. This is especially true when two similar microphones are placed in symmetrical relation to a performer.
