HR 54 Audio output
I currently have an HR 34 DVR which has both digital and analog audio outputs. In my system Zone 1 uses the digital audio output from the HDMI cable, but Zone 2 uses the analog output because my pre-amp requires it. The HR 34 has RCA analog audio outputs. I want to upgrade to the HR 54 which does not have analog audio output, only digital via Toslink or coaxial. So I will need to buy a digital to audio converter to get audio to my Zone 2. However, there are different converters such as converters that decode 2 channel stereo or converters that can decode 5.1 or 7.1 Dolby. What is the digital audio output of the Toslink and coaxial jacks? Are there multiple HR54 models (550?, 700?) and do they have the same digital audio outputs?
