Start with the connections on the equipment you already own. A digital coaxial audio connection uses an electrical S/PDIF signal, typically carried by a 75-ohm cable with an RCA plug at each end. Check that your source has a coaxial digital output and the receiving component has a matching digital input; an RCA-shaped socket alone does not establish compatibility. Read the labels beside the ports and consult the equipment manuals before choosing a cable. For a compatible stereo setup, one digital coaxial cable carries the audio signal between components, rather than the separate left- and right-channel cables used for analog stereo connections. Next, consider how the cable will fit into your listening space. Measure the route behind cabinets and between components, allowing enough slack to reach the ports without pulling on the connectors. Check connector housing dimensions if the sockets are recessed or closely spaced, and compare jacket flexibility and strain-relief construction for routing around equipment. Shielding is another construction detail to review, while gold-plated connectors offer corrosion resistance rather than a change in connection format. Prioritize the correct signal type and a practical fit over decorative finishes, and confirm the cable’s stated S/PDIF support instead of relying only on its appearance.

FAQ

S/PDIF stands for Sony/Philips Digital Interface. It is a digital audio interface used to send sound between compatible components. S/PDIF connections can use electrical coaxial cables or optical cables, so check which connection type your equipment provides.

Digital coaxial audio carries an electrical signal through a coaxial cable, typically with RCA connectors. Optical audio carries a light signal through an optical cable, commonly with TOSLINK connectors. The plugs are not interchangeable; choose the type supported by both components.

Red and white RCA ports typically carry right- and left-channel analog audio, not digital coaxial audio. Although the connector shape may match, the signal types differ. Look for labels such as “coaxial digital” or “digital audio” rather than relying on port color alone.

A passive cable cannot convert digital audio into analog audio. To connect a coaxial digital source to an analog-only amplifier, you need a compatible digital-to-analog converter with a coaxial input and the appropriate analog outputs. Confirm its supported audio formats before connecting.

Some 75-ohm RCA cables are specified for multiple uses, including S/PDIF digital audio, subwoofer connections, and composite video. Check the cable’s stated signal support before choosing it. Multiple supported uses do not mean the cable converts between digital, analog, and video signals.
