An S/PDIF coaxial cable can carry linear PCM or multi-channel Dolby AC-3/DTS digital content from a source device, such as CD or DVD player to an AV receiver or Surround Sound Preamp/Processor. Digital Coaxial Audio Connections use RCA-style connection plugs. This "CABLESETC" digital audio cable features proper characteristic impedance, fast frequency-independent signal propagation and effective shielding against EMI/RFI. This interconnect uses smooth, flawless, large cross-section tinned OFC as the signal conductor. A foamed PE insulation exhibits extremely low dielectric constant. It provides two layers of shielding: one OFC copper braid and one overlapped Mylar foil. Precision design and manufacturing ensures the characteristic impedance of the cable assembly remains 75 Ohms, +/- 5 Ohms. Precise soldering techniques using expensive solder create increased electrical integrity, maximum signal transfer, long term reliability, and guarantee performance under the most demanding conditions. The ultra-flexible PVC jacket enables easy installation, and resists binding and kinking which can cause errors in the signal path. This high performance S/PDIF digital cable is also ideal as a premium, extended length composite video cable for especially demanding video applications! "
