What do I connect to the mobile DVD player/receivers optical or coaxial (RCA) digital output?
The optical and/or coaxial digital outputs on a DVD player’s back panel are for sending various types of digital audio bitstream to compatible components. If you’re playing a DVD movie, the multichannel audio (Dolby Digital or DTS?) is sent to the decoder in a surround processor, which separates it into six channels of audio (front right and left, center, rear right and left, and subwoofer). Although coaxial connections usually have standard RCA-type connectors, the cable itself is specially designed to handle the much wider frequency bandwidth of digital signals. With optical connections, the signal is transmitted as pulses of light through a fiber-optic cable.
