Tech Tip:What Are The Best Cables To Use For S/PDIF?


S/PDIF is a digital audio format that stands for Sony/Philips Digital Interface Format. S/PDIF connections may be either optical or coaxial. The best cables for optical are made of glass and are very costly, so plastic fiber-optic cables are generally used. The best cables for coaxial are 75 ohm video cables, but standard RCA cables will often suffice. Coaxial cable lengths should be kept as short as possible.
