AES15-1991 (w2002): AES Recommended Practice for Sound-reinforcement systems -- Communications interface (PA-422) (Withdrawn: 2002)
Printing Date: 2000-03-15
Publication History: Pub. 1991; Withdrawn 2002
Abstract: This Audio Engineering Society (AES) Standard specifies the electrical characteristics of a balanced-voltage circuit for the interchange of serial binary signals for the control of sound-reinforcement systems. It provides for interchange among data terminal equipment (DTE), that is, computers and microprocessors, and data circuit terminating equipment (DCE). PA-422 is a mnemonic, signifying professional audio implementation of Electronics Industries Association EIA-422-A. Device control language is provided in an annex. [Current printing includes all device control coding additions to date.] An ANSI version available as S4.49-1991 has been withdrawn. (22 pages)
