BS EN 61606-1 discusses audio and audiovisual equipment and digital audio parts with a focus on basic measurement methods of audio characteristics. BS EN 61606-1 is the first part of the multi-series on audio and audiovisual equipment that is applicable to the basic methods of measurement of the audio characteristics of the digital audio part of audio and audiovisual equipment for all consumer use, professional use, and personal computer.
BS EN 61606-1 describes test methods for equipment that 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.
Note: BS EN 61606-1 does not apply to a lossy compression signal and also does not apply to power amplifiers.
BS EN 61606-1 on audio and audiovisual equipment is useful for:
A digital packaged medium may be used when it generates signals which are consistent with the digital sine signal generator, the signal generator for inter-modulation measurement, or the signal generator for group delay measurement.
The common measuring conditions and methods, described in BS EN 61606-1, 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.
