Can coaxial cable transmit audio?
Coaxial cables can communicate digital signals and therefore, they can carry 5.1 channel audio into a single cable. This is not possible in RCA cables.
Can you use coaxial cable for analog audio?
Coaxial cables with cinch connectors can transmit both analogue and digital audio signals. Cables with jack plugs are used in portable devices (smartphones) and for the input and output of sound cards. Both optical TOSLINK cables and analogue coaxial cables work in conjunction with the SPDIF interface.
Is digital audio out the same as coaxial?
In many ways, coaxial and optical digital audio connections are very similar. They both transmit S/PDIF digital audio and support uncompressed stereo PCM audio and compressed 5.1 DTS and Dolby Digital audio. The main difference is the connector and cable.
