DIN EN 61606-1:2010-05

This International Standard specifies the basic methods of measurement of the audio characteristics of the digital audio part of audio and audiovisual equipment for all of consumer use, professional use and personal computer. The common measuring conditions and methods described in this standard are used for the measurement of the performance characteristics of equipment having an audio bandwidth equal to approximately one-half of the sampling frequency of a system, where the audio information is processed in the form of digital data. CD players, DAT recorders, digital amplifiers, digital sound broadcast receivers and television broadcast receivers with digital sound are examples. The standard describes tests for equipment which has digital input with analogue output and analogue input with digital output. Future revisions of this standard will cover "digital-in/digital-out" and "analogue-in/analogue-out" tests. This standard is not applicable to lossy compression signals and power amplifiers. At DIN and VDE the responsible Committee is K 742 "Audio-, Video- und Multimediasysteme, -geräte und -komponenten" ("Audio, video and multimedia systems, equipment and components") of the DKE (German Commission for Electrical, Electronic and Information Technologies).
