Overview
The Digital Audio Converter, Dolby Digital (500081) converts one LPCM-encoded or
one Dolby Digital coaxial (S/PDIF) or optical (TOSLink) digital audio signal to a
standard left/right analog audio output, thereby allowing a digital audio source such as a
DVD or CD player without RCA analog audio output to be connected to an audio-video
receiver or TV.
Applications
Applications include commercial and residential audio systems, boardroom systems,
collaborative PC systems, and medical information systems.
