IEC 62537:2010 specifies the requirements for a digital loudspeaker interface based on the IEC 60958 series of standards and the MIDI specification. It maximizes flexibility and value by combining these previously separate standards. Together, the two standards provide a simple and flexible digital interface for loudspeakers. This bilingual version, published in 2010-09, corresponds to the English version. The French version of this standard has not been voted upon.
