Williams AV BA SYS4 Infinium Flex Assistive-Listening Bundle
The BA SYS4 Infinium Flex assistive listening bundle provides a comprehensive, future-ready assistive listening solution by combining two proven wireless audio platforms into a single integrated system. Featuring the FM+ T55C D FM/Wi-Fi transmitter and the Infinium CT1 Auracast controller/transmitter, the bundle enables venues to simultaneously broadcast audio over FM, Wi-Fi, and Auracast technologies. This flexible approach supports a wide range of personal listening devices, allowing every guest to access clear, intelligible audio using the device that best fits their needs.
The FM+ T55C D delivers dual-broadcast audio over traditional FM and Wi-Fi networks, allowing guests to listen with venue-provided FM or Wi-Fi receivers or stream audio directly to their smartphones using the free WaveCAST app. The Infinium CT1 adds Auracast broadcast audio, enabling direct streaming to compatible hearing aids, cochlear implants, earbuds, headphones, smartphones, and Williams AV Infinium receivers. Together, these three broadcast technologies provide exceptional compatibility while giving venues the flexibility to support both legacy assistive listening systems and the latest personal audio devices.
Designed for modern professional AV installations, both transmitters feature integrated Dante networking for seamless integration with digital audio systems. The included dual rack-mount kit installs both half-rack units side-by-side in a single rack space, creating a clean, professional installation. Designed, engineered, and manufactured in the USA and TAA-compliant, the BA-SYS4 is ideal for venues seeking a scalable, future-ready assistive listening solution that delivers maximum accessibility, long-term flexibility, and reliable professional performance.
