Williams AV BA-T1BK Infinium T1 Auracast Singular Transmitter

Williams AV BA-T1BK Infinium T1 Auracast Singular Transmitter

The Williams AV BA-T1BK Infinium T1 Auracast Transmitter expands a compatible Infinium system with additional audio channels or wireless coverage. It broadcasts low-latency mono or stereo audio to compatible hearing aids, cochlear implants, headphones, earbuds, smartphones, and dedicated Infinium receivers. An Infinium controller is required for operation.

The black finish helps the transmitter blend into dark ceilings, theaters, lecture halls, performance venues, and transportation facilities. Installers can place it on a wall, ceiling, shelf, or podium and connect it using one CAT5 cable. That single link carries digital audio, system control, and Power over Ethernet, reducing cabling at the transmitter location.

Bluetooth 5.4 LE Auracast transmission supports open or password-protected broadcasts with AES128-CCM encryption. The transmitter delivers up to 328 feet of open-space range when used with the Infinium BA-R1 receiver and provides less than 40 milliseconds of end-to-end latency under the specified conditions. Programmable output power helps integrators tailor coverage for individual rooms, adjacent zones, or coordinated multi-transmitter deployments.
