Using Dvd Player To Internally Decode Dd/dts 5.1 Digital To Analog And Send That To Reciever

[africanmarty]

hi guys i was just curious about using a dvd player to internally decode DD/DTS 5.1 and output it via analog 5.1 6ch output and send that to reciever by using the 6-channel external decoder input rca connecters. i was told that if the dvd player can do internal decoding it can send the signal through the rca 6ch output on the dvd player to a receiver. now granted this might work. But does it sound the same as if i was using a digital coax or optical cable from the dvd plauyer to the reciever and letting it to do the decoding. i mean its still 5.1 DD/DTS right (just going through analog rca and not digital coax or optical), it should sound the same.

the reciever in question is a yamaha rx-v357

for the those who are curious i know the reicver has a coax and optical and can decode DD/DTS in the receiver, this what just to ease my curiosity.

[africanmarty]

ok i can understand that one may sound a bit better, but the analog sound should represent that the same of the digital DD/DTS sound in that the analog sound from the reciever will be 5.1 DD/DTS 6ch too right ??

or for arguments sake lets say the DAC are equal in quality is there a sound difference between DD/DTS 5.1

through analog audio outputs 6ch 5.1 internally encoded in the dvd player played though the recievers analog audio inputs 6ch 5.1 --> speakers

or

DVD player bitstreamed digital (coax or optical) audio to recevier and encoded in the receiver --> speakers

I still rekon its iffy

DACS equal = same chips = same circuit

Option 1. your converting the digital signal in the dvd player, then via 6 x RCA cables (of ?qualty) then amplified in the reciever (acting as an amp - no processing).

Option 2. your sending a digital bitstream to the AVR via 1 cable, which is then decoding and amplifying

If your talking good quality cables - theres realistically no difference. Yes there are jitter issues with the sp/dif connection (bitstream) but theres also issues with adding extra electrical connections going RCA (different metals, connection quality etc etc) ... there are pros for using optical (toslink sp/dif) as this removes a potential electrical grounding issue between the player and the amp, but unless youve got that problem,..... well..

Facts are the DACS arnt going to be the same... one will have better ones and most importantly, one will have characteristics that YOU like more!

Get some reasonable quality RCA cables (shouldnt cost you more than $55 delivered from Selby's), hook it up and try it.. its really the only way you'll know..

If your thinking 'my dvd player didnt cost 55$' then just hook it up with sp/dif :-) its not going to sound better via the RCA cables!

Cheers,

It won't sound the same. In fact you will be degrading the signal since it has to go through about a metre of copper * 6, where it may pick up noise and interference and be attenuated slightly.

I would only do what you suggested if your receiver couldn't decode the higher-resolution audio formats and you had to use your DVD/Blu-Ray player to do the decoding.

[africanmarty]

ok thanks for the great info guys ireally appriciate it. now what are 'really good' rca cable brand ?? and where would recommend i buy them ??

thanks again - marty.

i gues i would be looking at a cable like this if the receiver couldn't decode the higher-resolution audio formats and you had to use your DVD/Blu-Ray player to do the decoding via 6ch audio and since the recevier would be right on top of the DVD/Blu-ray player i would only need the 3m cable

Dont waste your $ on Mon$ter cables - sure theyre good cables but horribly overpriced. You can get excellent quality cables locally for much much cheaper!

This will do the business (other sizes are available)

Other sizes here shorter is better

You need 3 pair (6 individual cables) for 5.1

Dont forget DTV members get 20% off (theres a code somewhere for it!) check the forum ad's

Thanks bites i was just doing some quick math and this is what i came to :

The shelby cables ( granted i would need 3 sets ) would come to AU65.85, and with the 20% off it comes to AU52.68

the monsters are US49.95 with the current exchange that come to AU53.30 from http://www.sonicelectronix.com/item_11210_...I306+6C-3M.html

Now i havent done the postage/shipping of each item but 53.30 for the monster and 52.68 for the shelby isnt that much of a difference plus the monster is one cable with 6 rca at each end ( wich is more practicle and less messy ) as apoosed to use 3 stereo rca cables from the shelby.

what do you think ?

regards Marty.

As mentioned, the Monster cables are overpriced, which means the ~$53 Monster cable is only really worth $10.

ok do you know a place in oz where i can get a good priced 6 channel rca cable ( that is connected as one cable with 6 sca at each end ) all the ones ive found are really expensive.

[glennb]

The Selby one's previously mentioned will be fine and at ~$60 are not expensive.

For what it's worth, I use this one for my HD player to my Denon and it's fantastic.

Slightly dearer though...
