Infrared Transmitter Unit MC-6300M/04
The MC-6300M/04 is a professional infrared transmitter unit developed for secure, interference-resistant audio distribution in multilingual conferences and formal meeting environments. Operating across the 1.7–4 MHz frequency range, it converts incoming audio signals for infrared transmission without being affected by daylight or common artificial lighting. Its multi-channel architecture, extensive RCA connectivity, interpreter console interface, and standard rack-mount design make it suitable for conference halls, government meetings, international forums, training centers, and simultaneous interpretation systems.
Product Description
- Secure infrared audio transmission: Infrared technology helps confine transmitted audio within the conference space, reducing the risk of interception from outside the room.
- Interference-resistant frequency range: Operation from 1.7 MHz to 4 MHz minimizes interference from common lighting systems and supports stable use under daylight or artificial illumination.
- Multi-channel conference support: Carrier frequencies 0–11 provide flexible channel allocation for multilingual interpretation and other multi-program audio applications.
- Digital PLL modulation: Digital phase-locked loop technology maintains accurate carrier frequencies and stable signal transmission throughout extended conference sessions.
- Professional audio performance: A dynamic range and signal-to-noise ratio above 80 dB help preserve speech clarity while limiting background noise and channel interference.
- Extensive source connectivity: Twelve RCA audio inputs and twelve RCA outputs support integration with interpreter consoles, conference processors, mixers, and external audio equipment.
- Dedicated interpreter interface: The 25-pin DIN connection enables direct integration with compatible interpreter console systems.
- Flexible HF distribution: Two BNC output connectors provide reliable connection to compatible infrared radiators and signal distribution equipment.
- Professional rack installation: The standard 19-inch rack-mount chassis allows organized installation in conference control rooms and centralized equipment racks.
