   Perhaps you have a brand and type of the amp ?

   phono sockets (marked    
   left and right).  I was under the impression that AC3 was the bitstream format   
   of dolby surround sound and required only ONE phono connector (or an optical   
   toslink connector).  Why do I have two phonos?  I don't have the ability to   
   give it a dolby    
   bitstream yet to test it (waiting on a part), but I did try connecting a   
   standard stereo analog input to the AC3 phono connectors, and it worked.    
   Should it have?  Could it be an analog/digital input?
