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. 

•  Model 979R converts Digital PCM to Analog Audio 

accepting 44.1 to 192KHz sampling rates 

•  Model 979T converts Analog Audio to Digital PCM 

outputting 48KHz or optional 96KHz sampling rates
