The »earisMAX« Bluetooth® Auracast™ transmitter

To this end, the device integrates all current standard ports for connecting corresponding audio sources: Toslink input and output (looped through / passthrough)(digital), analogue input and output (looped through / passthrough), HDMI for connection to the audio return channel (ARC)(digital) of TV sets and microphone input for the integration of older TV models in order to be able to pick up their audio signals acoustically.
