本国际标准规定了电影控制室和室内影院中磁性声音再现的A链电频率响应特性。它还打算与IS0 2969一起用于电影配音剧院、评论室和室内影院中电影声音的录制、监控和再现特性的标准化。 本国际标准涵盖了从换能器到主音量控制器输入端子的电影声音系统部分，应结合IS0 8590阅读，IS0 8590定义了35 mm和70 mm磁条打印的记录特性。

This International Standard specifies the A-chain electrical frequency response characteristics for magnetic sound reproduction in motion-picture control rooms and indoor theatres. It is also intended for use, in conjunction with IS0 2969, in the standardization of recording monitor and reproduction characteristics of motion-picture sound in studio 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, and should be read in conjunction with IS0 8590, which defines the recorded characteristics for 35 mm and 70 mm magnetic striped prints.
