Secure Infrared-Based Language Distribution for Professional Environments
The VLI IR Language Distribution System is engineered to deliver secure, high-quality multilingual audio transmission using infrared technology. Unlike traditional wireless systems, IR transmission ensures that signals remain confined within the physical space, preventing leakage outside the room and eliminating interference from external radio sources.
This makes the system especially suitable for government meetings, confidential conferences, and international summits, where data privacy and signal integrity are essential.
The system consists of IR transmitters, radiator panels, and portable receivers, working together to distribute multiple language channels simultaneously. With support for up to 32 channels, participants can easily select their preferred language using an intuitive interface.
Designed for flexibility, the receiver units are lightweight, portable, and ergonomically shaped, allowing users to move freely within the venue. The system also supports fast deployment and easy scalability, making it highly suitable for AV rental companies and event organizers.
