DVD Audio Connections


My A/V receiver (Marantz SR 8200) does not seem to recognize the multichannel signal from dvd audio discs. The front panel of the receiver indicates that it is receiving only front left and right signals (although sound comes from the side surrounds).

I have only the coaxial out from the dvd player connected to the receiver, although the dvd player has separate outputs for each 5.1 channel and my receiver has inputs for 7.1. Are these the connections I have to make to get multichannel dvd audio signal?

My receiver does not seem to have any problems recognizing the various surround signals from regular dvds.

Any help will be much appreciated.

First, let's distinguish between a regular DVD disk, and DVD-A. Your receiver will recognize the Dolby Digital and/or DTS 5.1 channel information from just the digital co-ax, but DVD-A disks (as well as SACD) are currently output from the player only in analog form. Therefore, you will need 5.1 sets of connections for DVD-A (and SACD) to carry the analog signals from the player to the receiver.

Be aware that the analog signals from DVD-A do not include bass management information for the low-frequency signals used to drive a subwoofer in home theater. I'm not familiar with the circuit details of your Marantz receiver, but my bet is that you will need a separate bass management component if you want to process a signal for your subwoofer.
To play DVD Audio, you must use the DVD Audio Player's 5.1 audio outputs. Your 7.l equipped Marantz receiver should easily accommodate the 5.1 worth of outputs. All you have to do is make sure you connect them correctly. (E.G., Center output to center input, subwoofer out to subwoofer in, etc...)

Your Marantz recognizes all the formats associated with regular DVD video discs like Dolby Digital, DTS, etc..., but these are strictly DVD video soundtracks that are carried by the digital cables (coaxial/optic).

Because of the music industry's copyright concerns, they've prevented high resolution multichannel recordings to travel digitally which, theoretically, could be duplicated digit by digit giving perfect copies. (Horrors!) Because the decoding is restricted to within the DVD audio player, you need the cables to transmit the signals to your A/V channel by channel. Hence, your need for all those cables between the DVD Audio player and the receiver.

Some DVD Audio players will "down mix" the multichannel high resolution DVD Audio disc to output two channel stereo. This could account for the A/V receiver's reading out two channels from your DVD Audio discs. You might try hooking up two old fashion RCA interconnects between the DVD player and A/V receiver and see what you get. Unfortunately, it won't be the sound of the new high resolution formats (24/96 plus).

Yeah, it was a drag buying more interconnects but it's fun hearing the new high resolution discs. Read DVD Audio reviews before you rush out to buy too many DVD Audio discs. Some older recordings reissued in the higher resolution format only reveal how poor the original recordings were. Some people get annoyed by a new multichannel presentation of a revered "classic". To some, it's like "coloring" black and white movies.

In short, not all multichannel discs will amuse you, some will astound, and a few will make you outright cringe. Read before you buy. Nonetheless, the higher resolution is a jump over the sound quality of the redbook CD's of the last twenty years. SACD and DVD Audio, the two competing high resolution CD formats, hold a lot of potential for the future. Buy those extra cables and enjoy the future.
Great -- there goes ANOTHER $300 worth of cables to plug into my $200 DVD player. Oh well.

I'm still not exactly clear how the connections work on the receiver side but I think this will be enough info to figure it out.

Thanks for the help.
Just to add to what was said above: In my HT system, unless I am senting the 5.1 analouge out DVD-A signal to the reciever, the recieved(or is it the player? Whatever....) downsamples the hi-res signal to 16/44 (ie: run of the mill CD "quality")
Note that Meridian, Pioneer and Onkyo have recently offered PROPRIETARY DIGITAL connections for DVD-Audio and / or SACD in their high-end models. This means that the connection can only be made Meridian DVD/CD player to Meridian processor, Pioneer DVD/CD player to Pioneer processor, etc., those having the digital feature. A much better solution is near in-hand.

Whoever they are, the people driving the copy protection issues have agreed on the"fire-wire" digital transfer format for the two high-resolution digital formats. So, in the near future we SHOULD be able to plug and manufacturers player into any other manufacturers processor using the open architecture fire-wire format. I hope so anyway; we don't need all those expensive analog cables!!
