hdmi arc vs optical vs coaxial

HDMI ARC, optical, and coaxial are different types of audio connections used to transmit audio signals from a source device (such as a Blu-ray player or TV) to an audio output device (such as a soundbar or AV receiver). 1. HDMI ARC (Audio Return Channel): It is an audio connection that enables two-way communication between the TV and a connected audio device using a single HDMI cable. It allows the TV to send audio signals to the audio device, and at the same time, receive audio from the device, eliminating the need for separate audio cables. 2. Optical: Also known as TOSLINK, optical audio connection uses a fiber optic cable to transmit audio signals as light pulses. It provides high-quality digital audio transmission, supporting surround sound formats. However, it only carries audio and not video signals. 3. Coaxial: Coaxial audio connection uses a coaxial cable to transmit audio signals as electrical pulses. It also supports digital audio transmission but uses a different type of cable compared to optical. Coaxial cables are less commonly used today but still provide a reliable and high-quality audio connection. In summary, HDMI ARC offers a two-way communication between devices using a single HDMI cable, while optical and coaxial connections transmit audio signals using fiber optic and coaxial cables respectively, with optical being more common in modern setups and coaxial being less used but still effective.
