o.k., so i'm a newbie and still trying to figure all of this. I've looked through previous posts but haven't seen this question addressed. My appologies if I'm rehashing an old subject.

If I buy a DVD-A or SACD where does the sound for the rear channels go? Do I have an option to route them to surround / rear surround (speaking 7.1 setup)?

The only info I found in the manual was a reference to not even use the analog inputs, but instead use optical in to let the 950 decode the signal.

So those folks who are using an SACD / DVD-A, how have you got it setup with your 950?

Thanks.

If you want the 6-channels of audio, you must connect the 5.1 analog output from the DVD-A/SACD player into the 5.1 analog input of the 950. Then you need to punch the "6-channel button on the 950 remote (make sure the AUD button is the "active" remote device).

With DVD-A, you can play a Dolby Digital (less quality) version of the DVD-A audio track, and this only requires the use a digital connection between the player and the 950. (This assumes the DVD-A disc has a DD audio track as well as the other 6-channel track).

Pretty reasonable question. Let me see if I can clear it up some...



If you are using the 6-channel analog input (which with DVD-Audio and SACD is what you want to do, so you get full benefit from those formats), then the surround back channels (speakers "6" and/or "7" in a 6.1 or 7.1 setup) will not get any signal at all -- both formats are limited to 5.1 (mains, center, surrounds, sub).



What you found is referring to the way the 950 handles either digital inputs or analog stereo inputs (such as the signal from your VCR or CD player) in regards to surround modes. The 6-channel input the DVD-Audio or SACD player will be using is not processed by the 950.

Aren't you forgetting about the bass management for the 6-channel input? I'd call that "processing".

Nope, not forgetting. The bass management on that input is analog, no digital processing involved at all.

Ah, you didn't mention "digital" processing in your reply.

But also, bear in mind, you can get the "double-bass" problem with the 5.1 inputs if you're not careful.

gonk...help me out. analog crossover in 6 channel bypass? i don't find any info on that in the manual. the bass management listed on page 46 doesn't include a different setup for 6.1 bypass. does this mean simply that all the bass management is analog, regardless of mode?

i've always referred to x-overs as passive or active. active x-over = analog?

also, what happens to the signal when you select 6 channel bypass and a stereo cd is playing? appreciate any help.

I'll do the best I can. From what I understand, the bass management on the 950 in general is handled in the digital domain (which is part of why stereo analog inputs are converted to digital normally). For the six-channel input, the signal must remain analog or the entire purpose of the input (i.e. an analog "pass-through") is defeated. Therefore, the bass management on that channel is being handled with analog crossover circuits (low-pass and high-pass filters).

If you have a stereo signal sent to the six-channel input, the filters will pass material below 80Hz to the subwoofer channel. If the bass management switch is on, a separate filter will remove material below 80Hz from the left and right channels as well.

Remember, the sixth channel IS processed digitially. The analog "crossover" is just an HPF; the DSP still handles the LPF work.

Additionally, as I understood it, the "correct" placement of speakers for DVD-A more closely mirrors that of the front, left, center, and two rear channels of a 7.1 setup, with the surrounds being the irrelevant speakers. Why is it, then, that the 950 routes the two rear channels to the surrounds instead of the rears? Better yet, why isn't there an option to route to one, the other, or both?

I didn't think that any of the bass management on the six-channel input was handled digitally. I know that the LPF on the stereo bypass bass management is digital (stereo inputs are digitally processed to get a sub signal and then discarded, the sub signal is sent to the sub output, and the original unprocessed stereo inputs used for the left and right outputs). Of course, the whole bass management debate has gotten a bit hard to follow at times...
