The Anyware MPC3 2-pin Multimedia Digital Audio Cable is designed to connect CD-ROM or DVD drives directly to the internal digital audio input jack on a sound card. By using this cable instead of a standard analog audio cable, you can ensure your sound card is receiving an ultra-high quality, hiss-free audio signal. This hard-to-find cable is compatible with sound cards that are capable of using digital CD signals, such as SoundBlaster Live.
