Sony/Philips Digital Interface, or SPDIF, is a common digital audio connector found on many laptops and personal computers. SPDIF cables are of the digital coaxial variety. The copper-core construction of SPDIF cables means they offer enhanced durability when compared to fibre optic cables. Coaxial cables also come pre-terminated, so you only need a couple of inexpensive parts and a few minutes to convert a coaxial cable to SPDIF.

  1. 1

    Examine the end of the coaxial cable and the threaded end of the F-to-RCA adaptor. Press the adaptor onto the cable's centre pin.

  2. 2

    Hold the adaptor with one hand while turning the cable's connector clockwise. Stop turning when the connector is firmly seated on the adaptor.

  3. 3

    Repeat the process for the other end. Find the black or orange RCA-style connector labelled "SPDIF" on the PC or laptop. Plug one end into this jack.

  4. 4

    Route the cable to a matching port on the receiver labelled "DIG." Alternately, use a numerical designation such as "DIG1." Plug the other end of the SPDIF cable into this jack.
