Sennheiser BTA 1 Wireless Transmitter
The Sennheiser BTA 1 is a standalone Bluetooth Auracast™ transmitter that adds next-generation wireless audio broadcast capability to any TV, projector, or audio source. Unlike traditional Bluetooth transmitters that pair with one device at a time, Auracast broadcasts audio to an unlimited number of compatible receivers simultaneously. This makes the BTA 1 ideal for multi-listener households, waiting rooms, and anyone preparing for the coming wave of Auracast-enabled hearing aids.
With optical (TOSLINK), HDMI ARC, and 3.5mm analog inputs, the BTA 1 connects to virtually any audio source. It streams using the high-efficiency LC3 codec with low-latency transmission, keeping audio perfectly synchronized with video. The extended 50-meter wireless range provides flexibility for larger rooms and open floor plans.
If you already own Auracast-compatible headphones or anticipate upgrading to Auracast hearing aids, the BTA 1 transmitter is all you need to broadcast TV audio throughout your home.
