SMPTE 202 – Motion-Pictures – Dubbing Theaters, Review Rooms and Indoor Theaters – B-Chain Electroacoustic Response

This standard specifies the measurement methods and characteristic electroacoustic frequency response of the B-chain of motion-picture dubbing theaters (mixing rooms), screening rooms, and indoor theaters whose room volume exceeds 125 m (4414 ft). It is intended to assist in standardization of monitoring and reproduction of motion-picture sound in such rooms. The goal is to have constant perceived loudness and frequency response from installation to installation, and from position-to-position within an installation. This standard does not cover that part of the motion-picture sound system extending from the transducer to the input source audio selector.
