This PureAV series kit provides ideal connections for your video and gaming devices and for equipment that supports DTS and Dolby Digital surround sound. It offers exceptional quality in both cables: digital optical fiber is immune to all forms of EM/RF interference for superior sonic accuracy, and S-video separates brightness from color using two separate conductors to create clean, accurate video. PureAV series S-video and digital optical audio cables use the highest-quality materials to enhance your home theater experience with crisp, clear images and natural, clean sound.
