The IR SYS31 SoundPlus® T3 Portable Infrared Audio System Kit is specifically designed to enhance assistive listening and language interpretation in environments such as courtrooms. Featuring the advanced SoundPlus® T3 infrared transmitter, this system provides reliable audio transmission with crystal-clear sound quality.
Ideal for easy relocation between different rooms, the system comes with a convenient carry case for simple transport. It offers impressive coverage of up to 32,000 sq ft (2,972 sq m). The T3 transmitter is securely mounted on a table-top tripod, ensuring a stable setup, while the omnidirectional conference microphone captures clear audio throughout the entire space.
The system includes handheld receivers that pick up the infrared signal, providing audio through lightweight surround earphones or a mono neckloop. The neckloop connects directly to T-coil hearing aids or cochlear implants, making it an ideal solution for hearing assistance in professional settings. Perfect for environments that require seamless, high-quality audio and accessibility, this system ensures effective communication for all users.
