The InfiniumĀ® Flex System provides everything needed to deploy a flexible assistive listening solution in public venues. Building on the proven combination of the FM+ T55CD transmitter and Infinium CT1 Controller, the system also includes FM receivers, earphones, and neckloops to support guests from day one.
The FM+ T55CD delivers audio over both FM and Wi-Fi, allowing guests to listen through venue-provided FM receivers or the free WaveCASTĀ® app on their smartphone. The Infinium CT1 adds Auracast audio, enabling direct streaming to compatible hearing aids, cochlear implants, earbuds, headphones, smartphones, and Infinium receivers.
By supporting FM, Wi-Fi, and Auracast technologies, the Infinium Flex System accommodates a wide range of listening preferences and accessibility needs. Guests can choose the listening method that works best for them, whether that means using a venue-provided receiver or a compatible personal device.
Unlike the Infinium Flex Bundle, the Flex System includes four FM handheld receivers, four surround earphones, and two neckloops, helping venues begin providing assistive listening services immediately.
Both systems include DanteĀ® networking for straightforward integration with modern AV environments. The included dual rack-mount kit provides a clean, professional installation within a single rack unit.
The Infinium Flex System is ideal for theaters, performing arts centers, houses of worship, conference centers, lecture halls, universities, government facilities, transportation hubs, and other public venues seeking a complete assistive listening solution.
