Does this work for the Yamaha receiver RXV463 and the ps3? The receiver has HDMI but i dont think it supports the audio. Please help. Thanks

From yamaha's page, it doesn't apply but not quite sure in actual = to paper.

Goodluck.:cool:

I think I drooled on myself:D. I have my volume at 30 which sounds like it did at 25 before. The bass is incredible:D:D:D:D:D. Im like a little kid right now:p
When i press select on the remote of the ps3 its showing Dolby TrueHD 5.1 Ch. 48 kHz. Is this correct?

Well, reading this makes me wonder if you ever had your channels calibrated? HK's own calibration routine is not that good AND it does not cover subwoofer. I would suggest getting a SPL meter and doing proper calibration. Not necessarily to hear if there is a difference in SQ as it really doesn't matter (I am sure you won't go back to optical no matter what) but to get the channels calibrated correctly.

Congrats on getting the HD tracks to work. I haven't jumped into it yet as my AVR7200 still has plenty of life left in it and I'm happy with the sound. Maybe when the standalone players reach sub-$100 I'll get one and connect it with analogs, for now I'll stick to PS3.

Is it a matter of source material or is HD audio from either 48khz - 96khz? I am confused. The 2 discs that I have with HD Audio are both 5.1 96khz and it streams at about 4-7 mps.

You can either have TrueHD and DTS-HD MA decoded in the player or the receiver. You don't need the lossless formats decoded in both places. To summarize the ps3 again:

1. The ps3 decodes TrueHD and DTS-HD MA internally.
2. The ps3 outputs the decoded signal as a standard LPCM output (the same thing you end up with if the receiver decodes it) to the receiver/pre.
3. HDMI 1.1 and above receiver/pre's can process the LPCM signal properly.

So you don't need the receiver/pre to say it supports TrueHD and DTS-HD MA if you are using a player like the ps3 to decode the lossless audio. You just need the receiver to accept and process a standard LPCM signal and pretty much all hdmi receivers do unless you have a very early version of hdmi. The 463 manual says it supports hdmi 1.2a on page 14. So you should be good to go as long as you hook the ps3 up to the receiver via hdmi and choose all the right connections in the set-up menus.

The source material is sampled and recorded at a certain rate. This original mastering determines much of the audio quality. Although the potential is there, audio tracks are often less than the maximum specs allow.

I've been meaning to buy an SPL meter for awhile now just haven't got around to doing it. Is this something I can hook up to my laptop and then to the receiver via RS232 for better results

It's a very easy manual task but you need to have reference signals. I used Avia so I can't remember if you can use the tones on your HK or not.

Lucky for me I already have the AviaII dvd so all I need now is the SPL meter. I watched Ironman lastnight on Bluray and loved the sound. I'm undecided if I want to mess with it but I guess it can only help:D

You definitely want to do a proper calibration. Write down your setting before and after, and let us know. The sound difference you experienced might be due to the higher resolution, or just change in output levels. The latter is very possible since your HK should have individual output levels for different inputs, and you switched from optical to HDMI.

You can always go back to your original settings if you don't like the calibrated sound. If you like your bass a little hot, you can add a few dB's after the calibration if you feel it is necessary.

I think Sami is right...

This is what I did (maybe I did something wrong...):
Lossless PCM through 5.1 analog output compared to 2.0 core through optical output from the samsung BD-P1500. The 5.1 analog was way louder but, because of base management problem and other calibration problem with my receiver (HK avr 8000), I decided to stick with the 2.0 core through optical. It’s now well calibrated and the sq is impressive.

Now correct if I'm wrong..the goal when calibrating with an SPL is to get all channels outputing at 70 dbs. I think I read this somewhere but I could be wrong.

Outputting the same level, whether its 70dB or something else. When you said you could hear the same level of volume at -30 what was -25 with the optical connection, most likely it was due to the HDMI connection being set 5dB higher than the optical settings. Some people feel louder system sounds better, that's why you want both connections to produce the same exact sound pressure level, then you can compare the differences in quality.

Now, calibration is done so you will get correct sound field from your surround system. If your mains are at 70dB, your centre is at 65dB, your left surround is at 76dB and right is at 72dB, it can't be good. Your sound field is not even and won't reproduce correctly the master track. Same with subwoofer, its not good to have it at 62dB or 88dB (although some prefer it very hot, ie. too high).

Thanks alot for your help Sami, I'm going to give this a shot this weekend after I buy an SPL meter. Just out of curiousity...in my case, when I run my EZEQ setup from my HK, what db level does the receiver try and set the individual channels at or is it mainly for distance and crossover settings. I imagine they must be close to what they should be at. Regardless, being a perfectionist:( I'm stll going to calibrate with an SPL. What is the recommended DB level for 5.1?

Sami

Your receiver should be close, but like I said, it most likely will not calibrate your sub. dB level should not matter as your volume control takes care of what the final output is.

If you calibrate your channels to 75dB, that IIRC is what is Dolby Digital reference level. It does not apply to DTS tracks, and I am not sure how it relates to these new formats. It really doesn't matter but lets say you do this:

1) Set your main level controls to 0
2) Set your receiver master volume to a level where your left main is outputting 75dB (lets say it is at -10dB)
3) Calibrate all your channels to output 75dB
4) Play your DVD with DD with the receiver at -25

You are now playing your movie 15dB below DD reference level.

The HK Does calibrate the sub, but I normally boost mine 3db above what the HKEQ sets it to. It also does a bit of bass management to adjust for room acustics, supposedly.

I checked the settings with a sound meter and got more accurate results if I ran the EQ at -28db rather than the recommended -35 also.

I bought a SPL meter today from sonicboomaudio. It's the Canadian distrubuter for SVS products. Little did I know its only a half hour from my house. Maybe I can get them to let me demo a SVS Ultra in my house:D. I believe it's the same analog meter from Radioshack in the States. I'm going to calibrate tonight. I'll post my results.

The answer is simple.
High definition sound > DD5.1
