Experience superb sonic clarity and accurate musical reproduction with this Premium S/PDIF (Toslink) Digital Optical Audio Cable from Monoprice! The Sony/Philips Digital Interface Format provides for a Digital Optical Audio signal, commonly referred to as Toslink. Toslink allows for the distribution of uncompressed 2-channel PCM audio or compressed multichannel audio, such as DTS® or Dolby® 5.1 or 7.1. Being an optical signal, Toslink is immune to problems that can plague electrical signals, such as crosstalk, magnetic interference, or radio frequency interference. This premium cable features a full-sized Toslink connector on each end, with metal connector heads and a metal mesh jacket. The metal jacket helps protect the cable from nicks, cuts, and kinks, which could cause damage to the internal optical fiber.
