2. SYSTEM INTRODUCTION
Brief introduction
LINEARCOM3000 is a series product of digital infrared language distribution system. It uses
both digital infrared audio transmitting and control technique and an IR digital infrared chip.
They own LINEARCOM3000's intellectual property. IRRC08 can be used in simultaneous
interpretation systems for multi-language conferences.
In simultaneous interpretation systems, the interpreter translates the speaker's speech, the
translated audio transmits through the conference venue by modulated infrared radiation
and the delegates listen to wanted language by infrared receiver via earphone.
The system can also be used for other audio signal distribution occasions, such as urgent
mode, free mode audio signal output.
This system is compliant to IEC 61603-7 (international standard of digital infrared transmission)
and IEC60914 (conference systems-electrical and audio requirements, same as domestic
standard GB/T 15381-94), moreover, it is compatible with other IR systems, compliant to
IEC 61603-7. Parts of IEC 61603 are used in this manual for a better understanding of both
theory and technique of the system.
