Technology Overview 14 Power Mac G5 Analog and digital audio The Power Mac G5 features a comprehensive set of audio capabilities not commonly found in personal computers. State-of-the-art optical digital audio input and output ports use the S/PDIF (Sony/Philips Digital Interface) protocol over Toslink cables for connecting to devices such as decks, receivers, digital instruments, and even home theater systems. The optical digital audio ports on the Power Mac G5 support stereo and 5.1 surround sound speaker systems. Because optical digital audio transmits data as impulses of light rather than electrical signals, it delivers pristine digital sound. Completing the audio features of the Power Mac G5 are high-quality analog stereo audio line-level input and output ports for connecting self-powered microphones and analog audio decks and devices. An internal speaker is included, and a minijack on the front panel makes it easy to plug in headphones for individual listening. See page 28 for detailed audio specifications.
