Infrared Transmitter Unit MC-6300M/12
The MC-6300M/12 is a 12-channel infrared transmitter developed for large-scale simultaneous interpretation and multilingual conference systems. It enables up to twelve language or programme channels to be distributed securely within the intended venue, giving each participant access to the appropriate audio feed. With Digital PLL modulation, professional interpreter-console integration, extensive RCA connectivity, and dual outputs for infrared radiators, the unit is well suited for international conferences, government assemblies, courtrooms, convention centers, and high-capacity meeting facilities.
Products Description
- Twelve-channel transmission: Provides up to twelve independent audio channels for multilingual interpretation, parallel programmes, and large conference applications.
- Secure infrared distribution: Infrared signals remain within the covered room, helping prevent audio leakage outside the intended meeting area.
- Reliable operation under lighting: The 1.7–4 MHz operating range minimizes interference from daylight and common artificial lighting systems.
- Digital PLL modulation: Precise frequency control maintains stable carrier signals and dependable operation throughout extended conference sessions.
- Clear channel separation: Crosstalk attenuation above 80 dB helps preserve intelligibility and reduce interference between language channels.
- Flexible audio routing: Twelve RCA inputs and twelve RCA outputs support connection to conference processors, mixers, and external audio sources.
- Interpreter-console compatibility: A dedicated 25-pin DIN interface allows integration with compatible simultaneous interpretation consoles.
- Expandable infrared coverage: Two BNC output connectors distribute the HF signal to compatible infrared radiators throughout the venue.
- Professional rack installation: The standard 19-inch chassis integrates neatly into centralized equipment racks and conference control rooms.
