Optical Digital Audio
The Power Mac G5 comes with audio capabilities that are not usually found on personal computers. The state-of-the-art optical digital audio in and out 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 5.1 surround-sound speaker systems. And since S/PDIF is an optical signal ā a beam of light ā you wonāt get any ground loop interference caused by copper wiring.
Analog Audio
The Power Mac G5 also features high-quality, analog stereo audio line in and line out ports.
