arc vs optical audio
"ARC vs optical audio" refers to two different methods of transmitting audio signals from a source device (such as a TV or soundbar) to an output device (such as a sound system or headphones). ARC (Audio Return Channel) is a HDMI-based technology that allows bidirectional audio transmission between the source and output devices through a single HDMI cable. Optical audio, on the other hand, uses a fiber optic cable and light signals to transmit audio from the source to the output device. Overall, both methods serve the purpose of delivering high-quality audio, but differ in terms of the cable used and the technology involved.
