I have not seen a blu ray player, will not the blu ray player able to decode TrueHD and output through its 7.1 RCA output,
Then why do they have 7.1 output, while in the AV receivers specifications they say 7.1 input to connect Bluray players
Kindly clear my doubh as I'm interested in buying sr506
Okay, this is going to be interesting and I will try to explain the best way I can.
Your blue ray player(BRP) will decode the True HD. Now the BRP has to send the signal to your Onkyo 506 correct? The Onkyo 506 has only HDMI passthrough, which means it is capable of receiving only Video and not audio. Audio has to be sent seperately to the Onkyo.
BRP to 506 Audio Connection:
Through an Optical/Coax connection: You will connect the Digital Out of the BRP to the Digital In of the 506. Now, this digital connection can support bandwidth for Dolby and DTS NOT TrueHD. So which means though your BRP can decode TrueHD it cannot send the sound to 506. So your 506 can receive only Dolby/DTS from your BRP. True HD can be sent to an receiver only through HDMI as it has the highest bandwidth capability
My suggestion, get a 606 which can decode TrueHD and be done with it.
Your next question, why does 506 says 7.1?
Well, it means it capable of handling DTS-ES (or EX which has a flag to force 6 channels) or Dolby Digital EX. When you play a DVD which is encoded in DTS-EX or NEO6 you will get a 7.1 channel sound. This sound can be passed via Digital/Coaxial out from your BRP to 506 as they can handle that bandwidth.
Though TrueHD and Dobly Plus are 7.1 the bandwidth required is higher so the 506 cannot play it bcos 506 has only HDMI Pass Through which will only reads Video signals where as 606 has a HDMI repeater which will read both video and audio and you can enjoy TrueHD.
So you have two options:
1. Buy 506, BUY A BRP which has 7.1 output and connected each to the 7.1 input of your 506 and play it in TrueHD (Like prakas suggested)
Eg: Sony BDP which has 7.1 analog output:
BDP-S5000ES | ES Series Blu-ray Disc? Player | Sony | Sony Style USA
Panasonic BD30K
Panasonic Blu-ray Disc Player
I would go with Option 2 (Like moser sugegsted) bcos
1. In option1, you need to invest in high quality 7 analog cables which will cost you a bomb
2. More clumsy wires running
3. All is based on a BDP, even if you are planning to buy Media PLayer you need to invest in one which has TrueHD coding etc
4. There is a debate that TrueHD via HDMI is marginally better than TrueHD via Analog cables
Hope i didnt confuse you more.
