Axiom Home Page Forums General Discussion Stereo Pink Floyd: DSOTM & WYWH DVD(A)

I guess I don't understand this Denon Link. How's that work? Digital only goes through your Optical or Coax or HDMI/DVI. The 6/7/8 channel direct audio connections are analogue cables...well at least they are on my HK.

The reason I ask, is my Oppo 970hd will not pass the SACD audio signals over the Optical or Coax outputs. Something to do with DRM, whatever that is. It will only pass SACD audio over the analogue or HDMI outputs.

Before I give Oppo a call, I want to make sure I'm comparing apples to apples with how you guys are doing things.

OK, DenonLINK is a proprietary interface that transmits the 6/7/8 channel audio over a digital connection from Denon's SACD/DVD-A units to a Denon receiver. I assume they've worked out some sort of deal where this is acceptable. Firewire (IEEE 1394) works the same way. DVD-A and SACD are not DRMed (digital rights management, ie the content producers taking away the consumer's fair use rights), but instead rely on the large amount of data to prevent digital retransmission.

Oppo does not have a DenonLINK output, so you can't use that. Neither does H/K, and I don't think either of them have firewire, either.

Your Oppo won't pass SACD over optical or coax because (theoretically) optical and coax don't have the bandwidth to support that.

Also, don't confuse digital audio with digital video. While HDMI can (theoretically) carry both, DVI is video only. And I believe HDMI carries the digital signal as an extension of the usual SPDIF (coax/optical) range, so it wouldn't be able to transmit SACD/DVD-A either. I could be wrong there.

Oh....thanks.

Didn't really make that any clearer, did I?

>>Your Oppo won't pass SACD over optical or coax because (theoretically) optical and coax don't have the bandwidth to support that.

... and even if they did, your player would not be allowed to use those digital links because they are not protected. DenonLink is protected (encrypted) so Denon is allowed to output SACD and DVD-A over *their* digital link.

Ah, OK, I didn't realize that.

I just recently (last week) bought a dvd player which plays both SACD and DVD-A. I have connect the analog connections from dvd player to my HK reciever. I have also downloaded the DSOTM DVD-A. When comparing the lossless DVD-A mix to the DD or DTS versions, the DVD-A on my system has waaaaaayyyy less bass. Is this experience true for everyone else? I double and triple checked my analog connections and they are correct.

Leaving aside the "downloaded DVD-A", you have to adjust the levels output from the player when you're using the analog outs, unless you're using the 6- or 8- channel DVD-A inputs on your H/K, which run the analog signals through bass management.

RD, as Ken mentioned, unless you've set your new DVD player to do the bass management(as described in the manual), you get none on DVD-A(unless you have one of the HKs which does bass management on the analog inputs; apparently you don't). None of the low bass is sent to the sub and all the other speakers simply run full-range.

Thanks for the info! As far as the other part of my email, this entire thread is based on internet distribution of this material.
