Infrared Transmitter Unit MC-6300M/08
The MC-6300M/08 is an eight-channel infrared transmitter unit developed for large multilingual conferences and simultaneous interpretation systems. It distributes up to eight language or programme channels through secure infrared transmission, helping prevent audio signals from extending beyond the intended venue. With Digital PLL modulation, twelve RCA audio inputs and outputs, a dedicated interpreter console interface, and dual BNC connections for infrared radiators, the unit provides a reliable foundation for international forums, government meetings, convention centers, courtrooms, and professional conference facilities.
Products Description
- Eight-channel audio distribution: Supports up to eight interpretation languages or independent audio programmes within one integrated conference system.
- Private infrared transmission: Infrared signals remain within the covered meeting space, improving confidentiality and reducing interference with nearby conference rooms.
- Lighting-resistant operation: The 1.7–4 MHz carrier frequency range supports stable performance under daylight and common artificial lighting conditions.
- Digital PLL frequency control: Phase-locked loop modulation maintains accurate carrier frequencies and reliable transmission during extended events.
- Effective channel separation: Crosstalk attenuation above 80 dB helps prevent interference between individual language and programme channels.
- Extensive audio connectivity: Twelve RCA inputs and twelve RCA outputs allow flexible connection to mixers, conference processors, and external programme sources.
- Interpreter system integration: The 25-pin DIN interface provides a dedicated connection for compatible interpreter consoles and interpretation equipment.
- Dual radiator outputs: Two BNC connectors enable signal distribution to compatible infrared radiators for expanded room coverage.
- Professional rack installation: The standard 19-inch chassis integrates neatly into centralized conference control racks and equipment rooms.
