適用范圍：This International Standard specifies the A-chain electrical frequency response characteristic for photographic sound reproduction in motion-picture control rooms and indoor theatres. It is intended, in conjunction with ISO 2969, to assist in the standardization of recording monitor and reproduction characteristics of motion-picture sound dubbing theatres, review rooms and indoor theatres. This International Standard covers that part of the motion-picture sound system from the transducer to the input terminals of the main fader.
