Chris and everyone else who have commented on this:
First of all, a BIG thanks go out to you!! I really appreciate it!
How is the bass management set up in the OPPO
DVD player? I'll need to check over the weekend to be certain, but I'm 99% sure it is as follows (which is what Oppo recommends for high resolution audio content transmitted via HDMI):
Down-mix set to 5.1 CH
Front Speakers set to Large
Center Speaker set to Large
Surround Speaker set to Large
Subwoofer set to On
Digital Output set to Raw
HDMI Audio set to Auto
SACD Output set to PCMfyzziks
is correct about the bandwidth. A note from the Oppo users manual
regarding the reason why HDMI Output Video Resolution is important, even for audio, is as follows:NOTE
If you use HDMI to connect audio to an HDMI A/V receiver or audio processor, it is
recommended that you choose 720p or higher HDMI output resolution when playing high
resolution audio content (DVD-Audio and SACD). According to the HDMI specification, the
bandwidth available for audio is proportional to the total bandwidth used by video. At
480p/576p resolution, the HDMI specification can only support 2 channels of audio with high
sample rate (up to 192kHz), or 8 channels of audio with standard sample rate (up to 48kHz).
Depending on the capability of your A/V receiver or audio processor, if you play high
resolution audio content at 480p/576p resolution, you may get reduced audio resolution,
incomplete audio channels, or even no audio/video output at all. Choosing a high HDMI
output resolution such as 720p or 1080i allows enough bandwidth for all high sample rate
So I chose 1080p (initially), thinking if 720p is the minimum, 1080p will be at least equivalent, and possibly better. I know it doesn't make a whole lot of sense, but setting this to 720p does seem to take care of 80% of the problem.
will be able to compare 720P versus 1080p from his Oppo 980H and comment on any differences.
As it stands now, based on what everyone is telling me, I may just have to reduce the sub level in the Integra (from -4.5 currently, to say -8) and be satisfied with that.
I have not noticed the overwhelming bass problem in movies, where the signal is also coming from the Oppo 980H to the Integra via HDMI. My time spent watching movies is minimal versus listening to music. Regardless, since the problem was so severe, I believe I would have noticed it in the half dozen movies I've watched over the last 2 months or so.
I don't have either a Bluray or HD-DVD player for comparison.
To shamus and HDTVChallenged
, how would the +10dB LFE boost be getting applied twice? And please keep in mind that the overwhelming bass problem is experienced when playing music (SACD's like James Taylor's Hourglass, for example).
Thanks again to all,
