I have a BD 390 blu ray player hooked up to an older (3 years old) Pioneer receiver via 7.1 Multichannel inputs (I have a VSX-1016). My Pioneer receiver does not have an HDMI audio input... and I opted to connect the blu ray player via the multichannel inputs because the BD player has on-board DTS-HD, etc. decoding built-in (my pioneer does not have the ability to decode those HD tracks).

What I didn't realize is that the multi-channel inputs bypass the speaker settings I have on the amp.

I have tried running the sound from my BD player to my amp using an optical cable. I understand that this does not allow for DTS-HD to be used... but I've found there to be some lip-sync issues when I do that. Also, I've noticed that my sub (hooked up to my receiver via LFE cable) behaves differently when the BD player is decoding the audio and passing it to my amp via multi-channel 7.1 hook ups. What happens is that the sub is less active and only plays the lower lows (and not the mid range lows that come out of it when I switch the audio input to optical cable).

So, I've been considering getting a new amp. I've been interested in the new Elite VSX-21THX. It has the DTS-HD decoding on-board (obviously) and also has HDMI audio and video inputs. My assumption, all along, is that a new receiver connected to my blu ray player via HDMI will allow me to receive an audio signal from the blu-ray player that is equal to the current multi-channel set-up I have now, but will also allow the new receiver to all the decoding WHILE taking advantage of things such as bass management and my amps speaker settings. I'd also like to be able to bring in audio from the BD player that isn't 7.1 (say, a 5.1 track) and allow the receiver to turn it into 7.1.

My question is this, though: I've read one of the knocks on the VSX-21THX is that it only has 5.1 Multi-Channel inputs and not 7.1. Why would this matter???? Isn't the best option to have the audio coming out of your BD player via HDMI anyway? So why would anyone care about only having 5.1 multi-channel inputs.

Outside of arguing over receiver models, etc., I'm hoping someone with some more experience might be able to confirm or dispell my assumptions (above) and help me understand my options.

Thank you all and happy thanksgiving.

Hello,
If you purchase the VSX-21, you would be using the HDMI inputs to decode True HD/DTS-MA in the receiver and would not be using the multichannel inputs.

Where the multichannel inputs might be handy is if you have a SACD player and want to use the multichannel input for that.

Your experience with your older AVR and the multichannel inputs is common. Often the issue is with bass performance. You should be able to raise the subwoofer level via the Blu Ray Player. Still getting a modern AVR will also give you Room Correction and better integrated bass.
Cheers,
JJ

Two thoughts: first, when you use the HDMI connection your receiver is decoding the audio, and when you use the analog connections your player is. So, whether this means the receiver will do the job equally as well or not is completely dependent on the differences between the decode circuitry in the player VS that in the receiver. It is impossible to know if it will sound better or worse. You won't know until you try!

Second, if the receiver only has 5.1 analog direct inputs, then that's only something you need to take into account and is not necessarily anything to "slam." Do you currently use a 6.1 or 7.1 speaker setup?

I currently have a 7.1 set-up...

I'm not all that psyched about the multi-in's bypassing my settings in the AVR. Kind of defeats the purpose... doesn't it?

Anyhow... not sure if I would ever need multi-channel in's in the future (that is, of course, until something new comes along that the receiver can't decode....)

Most of the time information in channels 6 and 7 is being created (synthesized) from the surround information in channels 4 and 5. There are very few (as in a handful) of movies with discrete information in channels 6 and 7, so it was me, simply lacking analog inputs for channels 6 and 7 would not cause me to bypass a preamp I otherwise liked. :)
