A:Answer Hi,
An eARC(enhanced audio return channel) HDMI port enables the sending of audio to a TV that originates from cable, satellite, streaming, or source devices to be sent to an AVR or sound bar through a single HDMI cable. This ensures the simplicity of the connectivity and that the original audio can be experienced.
If an Optical port is important to your setup, this input is available starting with our Q8F Series.
