The NAD T775/T785 AVRs w/ HDMI 1.3 Thread! - Page 102

I'm an Italian owner of a nad t785 and I have a problem with HD audio streams conveyed through my pc with a ati hd 5770.
In practice I glu latest Catalyst driver with a 10.9 win 7 64-bit operating system but my card only sees Dolby Digital and DTS.
Many have told me that it could be a problem volvo edid and ask in this forum that I think best of all if anyone has solved this problem.
I state that I have a smooth nad t785 with original fw also because I do not know where to find it and whether it is compatible.
Thanks in advance for your answers and sorry for my English.

Thanks for the link. I held off on purchasing the VM200 and AM200 cards for my T785 once I realized HDMI 1.4 and 3D video began picking up some steam. It will be interesting to see the full capacity of these new modules, as well as the price and release date.

Looking into the NAD T 785 but am confused about the non HD versions. So the basic module does not include HDMI inputs without purchasing a High Definition MDC Upgrade Module? Or am I way off base here?

I bought the basic T775 model a couple of years ago and it does have HDMI inputs and does do full 1080p HD video (as does the T785). The VM200 video module upgrade just has a better video processor (Sigma Designs VXP broadcast studio quality image processor), but the base model video processor works quite well.

If you only need pass through for video then you do not need the module upgrade. The basic modules should have 4 HDMI inputs

Thanks NCCaniac and jdc115!

How does the NAD T785 compare to the newest Receivers introduced at CEDIA 2010 as to 4 ohm operation?

I have bought the t785 a few months ago , since then I tried all the tricks to set up the unit. I can't get sufficient sound levels if I run the audio through the HDMI inputs. Even if I drive the volume to max ( which on my screen shows -10dB, is that correct?) I get just a moderate sound level in most cases it is not enough for my room which is fairly large.

Is there any way to control the sound level for the HDMI (digital) inputs?

I run the receiver in 7.1 setup with Paradigm studio 100 & matching surrounds and center. The problem comes when I try to listen to programs from the Bell receiver via HDMI or from the OPPO 83 from HDMI, or run the computer audio via optical cable to the receiver.

On analog sources the level can be boosted and I get acceptable sound levels.

Any suggestions

This is very strange, before or after you ran Audyssey? Given you speakers, I can not imagine running at his level at all

ricci1220,

As jdc115 states, that is VERY strange. It should be screaming at that level (my room is at 85db when at -10). BYW, the level goes above 0 (IIRC, it goes to +14), but you should not need that. If you ran Audyssey, it sets the reference level to 85db at '0', so if you want to go above ref, you just go above 0, at -10, it should be fairly loud. You're speakers have sufficient efficiency that it should not be a problem. How are your other sources (non-HDMI)?

Funny! On my display, the maximum level is +1. After running Audyssey and adjusting the subwoofer's gain control a few times, the speaker levels were:
Front Left: +9db
Front Right: +9db
Surround Right: 0db
Surround Left: +1db
Subwoofer: 0db

I use a phantom center in a 5.1 configuration.

Perhaps, you could look at your Speaker Level settings. One thing I noticed is that with the level control on my subwoofer set at maximum, Audyssey had to compensate for the excess gain by lowering the subwoofer to -12db and raising the level of the front speakers to the 12db maximum. After I turned down the subwoofer's own level control a bit at a time, the rest of the speakers were able to balance the outputs better. When I reached about 2/3, Audyssey finally started raising the subwoofer level. At 1/2, Audyssey started lowering the other speakers' levels. The subwoofer's control is now at about 1/3.

I assume that if your sub's gain control is set too low, Audyssey would have to compensate by lowering the level of the rest of your speakers. If I'm interpreting my results correctly, if any speaker is set by Audyssey at +/-12db, something in the system is either out of balance, out of phase, not connected or not set up properly.

Menu>Setup Menu>Speaker Setup>Speaker Levels

Yes, that's a great point! I always run just the primary LP, calculate and look at the SW level and adjust the subs levels to hit 0db, then I do the whole run. With that, the rest of my speakers fall within + 5db.

I have run Audissey first. I don't recall how it sounded before Audissey but certainly not significantly louder.

Thanks,

That is one of the things I found very strange I can't drive the amplifier beyond -10 DB I'll try to run the Audissey again as suggested in other posts.

My actual settings are:
Front left = +7dB
Center = +10 dB
Front right = +6 dB
Surround R = +8
Back R = +6
Back L = +10
Surround L = +8
Sub = - 11 dB

I may have the sub turned too high I'll run it lower and repeat Audissey

If your individual speaker volume setting are in the plus's then this will alter the master volume - manually set them all to 0 and IIRC, the T785 master volume will go up to +18

Audyssey did not work for me with the T785 and my speakers and preffered it to off - It sounded as if I'd unplugged the tweeters - not nice

Has anyone heard anything else about the new MDC cards mentioned at CEDIA?

That is probably due to either room acoustics or placing the Audyssey microphone in a "hot" area. When I set mine up, I located the microphone at exactly the position of my head where I would sit in the center of the sofa. I suspended the Audyssey's microphone in that position to eliminate any possible reflections from under it. That worked very well for my system.

The main reason the fronts were set by Audyssey at +9db is that they are Magnepan 1.6QR's; which are very inefficient (86db @1w).

This is what I have read about the new MDC cards;

AM250: similar to AM100, but with more powerful DSP and Audyssey MultEQ XT32(32-bit Audyssey room correction)

VM150: HDMI 1.4 with 3 x HDMI-in / 2 x HDMI-out, Audio Return Channel and 3D pass-through

VM150X: Extension module for VM150. This gives an addition of 3 x HDMI-in (6 all together) and 2 x Component-in. VM150X is to be used instead of the existing Component-module

thanks! I wonder if the AM250 is considered better than the AM200? I currently have the non-HD t785 so it sounds like I have to get the vm150 & vm150x in order to retain my 4 hmdi inputs in use. KInd of sucks, if they charge $$$ for the 150x. And I wonder if the number implies the video processing is less powerful than the vm200.

I just got a NAD T743 and hooked it up but there is no sound coming out of the speakers. I have had 2 different receivers before that worked just fine but the NAD does not have HDMI. So I went into the Pioneer 51 (Bluray player) menu and set video for HDMI and audio for optical. Is there another setting I am missing? Cant figure out why there is no sound.

Can you please explain this about "reference level" to me? Is the sound pressure in the room 85db when the volume is at 0? Maybe I´m stupid but 85db does´nt seem loud to me. At volume 0 it should be very loud.

Regards

Alma321, did you go into the settings in the NAD and assign the optical port you are connection to the Pioneer? Confirm that you did, is should work fine.

Hello cavchameleon. Not too sure what you mean? Are you referring to the Listening Mode in the setup menu? I set the Analog In to DVD and the Digital In to Optical 1. I also set Analog In to DVD and also tried changing it to Off. But when connecting my BluRay player with analog cables or the Optical cable I do not get any sound out of my speakers.

Hi. I was referring to making sure that the OPT1 (if that is what you are using) is assigned to DVD and making sure you selected DVD as the source. For this receiver, OPT1 has a default assignment as DVD, but you need to verify that. Using your OSD, go to the INPUT SETUP, check INPUT for DVD, make sure the Digital In is on Optical 1 (you may have already done this, but just to make sure) and then save it. Also verify that in your speaker setup that everything is set correctly.

Yes, I have done this. I will play around with it more when I get home. Thanks cavchameleon.

Paul Barton of PSB along with factory reps from NAD will be at Saturday Audio in Chicago on Dec 2. Hopefully we can get some information on the MDC new cards then.

Nek, I think you should follow cavchameleon's advice on running Audessey set-up. I couldn't get my 7.1 PSB speaker system properly balanced till I began running only the initial center listening position pings around the speaker system and then calculating off that one run to see what level it had for my PSB subwoofer. Then I adjusted the subwoofer output level and repeated that one-time-through pinging and calculating till I got a 0db or within 1 db either way level for the subwoofer on Audessey's readings. Once I had the sub output level so it yielded a near-zero sub level in Audessey, I repeated the full Audessey calibration procedure pinging all the 7.1 speakers through 8 different microphone positions before calculating. Then I got excellent Audessey room adjustments, with accurate distance readings to all my speakers. The only deviation I'm running off the Audessey settings is to reset my PSB center channel speaker's crossover lower to take more of the deep bass than Audessey wants to give it. I'm a 64-year-old male and I find I need to run that bass content through the center channel, rather than through the subwoofer, so I can hear voice dialogue in programming distinctly.

Also, to another questioner, note that all the modules in the HD versions of T765, 775 (which I have) and 785 have multiple HDMI connections. The upgraded modules about to be released, however, will have the latest v1.4 version of the HDMI technical standard for cables/interconnects. Google "HDMI v1.4" for an explanation of the new standard's capabilities.

Cool! Are you going to meet the in person? Keep us posted (and on the prices of the cards).

I may have to work that nite, but hopefully someone else can make it or I will email the owner and hopeully he can get answers.
