12 Technical Specifications

12.1 System Specifications

12.1.1 Overall System Characteristics
The microphone system conforms to IEC 60914, the
international standard for discussion systems. However the
functionality of an Interpreter Unit differs from the standard.
Audio performance specifications are measured from the
audio input of a Discussion Unit to the headphone output
of a Discussion Unit.
