Hello Kal,

I just bought an Oppo BDP-83 SE and hooked it up to my older surround sound processor (Anthem AVM 20) via the former's 5.1 analog outputs. I do not yet have an HDTV, but will be buying one tomorrow, and intend to connect the Oppo's only HDMI out directly to the TV, as the Anthem does not have HDMI capability.

Are you suggesting that doing this will somehow compromise the HD audio?

Thanks,
Ken J.

You will certainly get high quality analog output from the 83SE but you have to see what other processing features you need, such as options for bass management, speaker distance, speaker levels, etc. You can do this in the Oppo but its options are somewhat limited. I doubt if the AVM20 can do this without redigitizing the signals and I do not even know if it can do the latter. I know the D2 can.

So, what are your needs?

  Hi Kal,
  
  Thanks for your response. My needs for bass management, speaker distance, speaker levels, etc. are pretty simple, and seem to be easily handled by the Oppo. I only have front speakers and surround speakers, all large enough to handle full range signals--especially the front speakers (B&W 801 Matrix with North Creek crossovers), which actually go lower than the subwoofer I used to own.
  
  Thus, I have used the Oppo's setup menu to set fronts and surrounds to large, sub to none, center to none, and rear surrounds (for 7.1 setups) to none, and have set speaker distance to 10 ft for the fronts and 6 ft for the surrounds. Levels were surprisingly close without adjustment, as measured with my Radio Shack SPL meter, but the Oppo allows for level adjustments in 0.5 dB steps if needed.
  
  As far as I'm concerned, this sounds great through the Anthem AVM 20's 5.1-channel inputs, which I have currently configured to "Anlg-Dir" (or analog direct pass-through). I also have the option of re-digitizing the signals if I want to use the Anthem's DSP capabilities, but I haven't tried that yet, reasoning that the extra A-to-D and D-to-A conversion isn't likely to make the signal sound any better.
  
  However, if I run into any issues with the video lagging behind the audio, I may have to use the Anthem's "Anlg-DSP" setting, which would redigitize the signal and allow me to apply the Audio Group Delay feature. With any luck, though, that won't be necessary.
  
  So, assuming I'll be able to use the Oppo/Anthem as currently configured, do you think there would be any compromise to the audio by using the Oppo's only HDMI out to the TV (for video only)?
  
  Thanks again,
  Ken
