Audio Authority Authority Digital Audio Converter 979R User manual

The Models 979R and 979T provide seamless digital/analog
audio conversion between your system’s audio components.
Housed in a compact, mountable enclosure, the 979R converts
digital audio to stereo analog signals and the 979T converts
stereo analog signals to PCM audio, offering the perfect solution
for interconnecting mismatched audio signals. Used together, the
converters form an effective method of transmitting two audio
channels where only one coaxial cable is available. Their high
bandwidth circuitry and use of premium parts ensure accurate
and realistic sonic reproduction for the highest fidelity in audio
systems.
