    Abstract - (Show below) - (Hide below)

    Applies to conference systems and to parts of which they are composed or which are used as auxiliaries to such systems (headphones, microphones, amplification equipment). Describes the different types of conference systems with both wired and wireless systems, and specifies the basic electrical requirements of audio equipment for conference systems. Prescribes the minimum requirements for conference systems in order to ensure interchangeability and optimum performance under conditions of normal operation.
