High-power digital infrared radiator VIS-VLI701B
Model VIS-VLI701B
Overview
High-power digital infrared radiator designed for large conference rooms, auditoriums, and venues requiring wide IR signal coverage.
Offers a range of up to 76 m with a ±25° radiation angle, allowing extensive areas to be covered with fewer units than a standard radiator.
The high density of 540 IREDs and peak power of 27 W/sr ensure a robust and stable infrared field for reception by language receivers.
Its electronics include cable delay compensation and thermal protection functions, ensuring reliability in continuous use.
