Bluetooth (BT) transmitters convert audio signals from non-Bluetooth devices (e.g., TVs, PCs, or stereo systems) into wireless streams, enabling compatibility with Bluetooth headphones, speakers, or hearing aids. Avantree’s transmitters, like the Audikast Plus, specialize in low-latency audio (<30ms) using Qualcomm aptX HD codecs, making them ideal for syncing video and audio. They often feature dual-link pairing and optical/aux inputs, bridging analog and digital audio ecosystems effortlessly. How does a BT transmitter work? A BT transmitter captures audio via wired inputs (optical, aux, or RCA), digitizes it using a DAC (digital-to-analog converter), and broadcasts it via Bluetooth protocols like aptX LL....
