Official NAD T175 Surround Processor - Page 2

post #31 of 4751

I think the tech person was in error, and that the HDMI inputs on the NAD T175 will process LCPM multichannel audio at least, along with the older bitstreams.

It would not interest anyone to have an HDMI prepro that had only video switching functions for its HDMI ports in 2007. That would be patently absurd. HDMI 1.1 or 1.2 I can understand, but not HDMI video switching only.

Amen.

Uzun, I sure hope that you're right. If NAD can release this in mid-2007 with full support for Dolby TrueHD and DTS-HD and HDMI 1.3, then they have a potential winner on their hands.

The stuff about upgrade cards, if true, would be a bonus.

I doubt it will be HDMI 1.3, probably HDMI 1.1 or 1.2. I would guess it will handle the older format bitstreams as well as multichannel hi-rez PCM over HDMI, and perhaps SACD DSD over HDMI as well (which is enough).

I'm guessing it will be out in the Jan-March 2007 timeframe, not mid-2007. I would be shocked if there were any sort of upgradeable cards in it, I would guess this has a near zero percent chance of being true.

Keeping my fingers crossed anyway.

I think sc10000 may be correct, the NAD T175 may currently be specced for HDMI switching only, with no audio processing of any kind via HDMI. That would be a dissapointment if true, but like he said I think specs are subject to change at this point.

No audio processing of HDMI, if true, would make this prepro very unattractive to me. I don't need 1.3 but like most people want to be able to send the new formats as decoded multichannel LPCM via HDMI at the very least. A receiver or prepro that can't do at least that is not in the running at this point in time.

Is the rightmost logo on the bottom left of the 175 an HDCD logo? THe logo is easier to see on the NAD 785 receiver photo than the T175 photo. I think it might be the HDCD logo. The one furthest to the right but in line with the HDMI logo.

Any idea if this unit will process HDMI LPCM multichannel audio at all, or if the HDMI ports are for switching only, and simply pass through all video and audio data.

When they say HDMI Audio/Video inputs, I assume they mean they PROCESS audio. I cannot imagine they just pass it through, the way the people at NAD have suggested. There must be some miscommunication due to this design being preliminary and the tech ppl at the NAD help line not understanding the implications of HDMI for audio.

The new receiver and prepro will almost certainly not be HDMI 1.3 but they have to process HDMI 1.1 or 1.2 audio, one would think, to even exist as a new product in Jan 2007.

It seems that there is more going on than simple passthough in the HDMI inputs, at least with video - hopefully this means that audio processing via HDMI is supported as well.

Mike, do you have the MSRP for the T785 receiver?

Sejin.

Well the big question we are all waiting for is...Do these units process HDMI audio data or not? If they do, at what revision level? HDMI 1.1 (LPCM multichannel only), HDMI 1.2 (same as 1.1 plus DSD audio streams from compatible SACD sources), or HDMI 1.3 (all data formats as encoded data or LPCM).

NAD tech answered my question regarding HDMI finally in their help area. They said their initial information regarding HDMI pass through was incorrect, and it will process HDMI audio data using the "current standard" whatever that means. I assume that means HDMI 1.2 or 1.1
post #43 of 4751
Thanks, uzun. That is indeed good news. However, the proof of the pudding will be testing it once the T175 hits the streets. Hopefully it will not have the HDMI issues experienced by the likes of the Anthem D2 et. al. To be realistic however, there will always be issues, it's just how many there are and how quickly the issues are resolved.

Got my fingers crossed that this is going to be good.
post #44 of 4751
this looks interesting

will keep an eye on development
post #45 of 4751
Just a thought here. The current NAD series of receivers and pre-pro's are labelled T7*3 (in the case of a receiver) or T163 (in the case of the pre-pro). Why skip that and go with labelling things as T175. I am assuming that the receivers will be labelled as T7*5 as well. Did NAD develop a 4-series and scrap it? The last time NAD released new receivers was in 2003 / 2004. They did however, release DVD players with the 4-series numbering scheme such as the NAD T524 and NAD T534. Just wondering...

because now they use a 5-sided dice with no even numbers

Huh?
post #48 of 4751
Here's the preliminary datasheet for the NAD T175. In the specifications, it lists HDMI 1.2 as the standard used. If you look at the rear panel, there is a USB port (to do with the remote control) as well as an ethernet port. It certainly makes for an interesting read.

Anticipated ship date is Q4 of 2006 with MSRP set to $1999.[ED]

any news about this pre/pro out in the market?

"Audyssey MultiEQ XT Room Correction with custom NAD developed target response curves."

I wonder if that includes more capable handling of the low bass, which seems to be a weak point of MultEQ.

I imagine that is the case. Paul Barton is smart enough to know that we are accustomed to some room gain, rather than total elimination of it. If you eliminate the boom, you have to compensate by raising the overall amount of bass a tad.

This unit is just incredibly well designed product.

This is fairly typical of NAD. If a unit sticks in the line unchanged as others evolve, they do a "catch up" number. The T744 and T754 are out now, but by next year, everything will end in "5". I have a feeling that "5" may stick around for a couple of years though. The new stuff is so good and so upgradeable that I suspect there won't be a "6" series until 2008 at least.

"Paul Barton is smart enough to know that we are accustomed to some room gain,"

Paul Barton of PSB? What is his connection with this product?

Also, I'm not sure the issue is room gain. I've seen before/after room responses of MultEQ, and the bass <60 Hz is very nearly as lumpy after as before "correction".

"The new stuff is so good and so upgradeable"

For the manyth time in this thread, what evidence is there that this unit is upgradable?

Thanks

Not to pick on NAD in particula.,r as many if not most/all pre/pro mfgr's are guilty, but why only one HDMI output?

Many have more than one dispaly, like a projector and smaller display.

NAD and PSB are sister companies. Paul lent a hand in tuning Audyssey for NAD and that is a very good thing as he is an expert in correlating subjective and objective data.

I don't know, do you know what "card-based" means? Have you seen the back of this machine?

Noah, do you have anything nice to say ever any more about anything or have you just decided that bitching about everything is the way to go?

The card to do it is very expensive and 80-90% of the population probably doesn't actually need it. Eventually, everything will have dual HDMI outputs. You can buy after market 2-way HDMI splitters for about $300 (and are about the size of a pack of cigarettes) if that gives you an idea of why it's not an onboard feature.

There's little new that I can contribute to all this but I was told that (1) the showing for the T175 at CEDIA was just a preview and (2) that the unit will be officially unveiled at CES 2007 in January. There will be lots of interest. ;-)

Hell yeah!!

For a look at the back of the machine, please click on the words "preliminary datasheet" in my post (#48) earlier up this page.

Just heard of a further delay, probably back to April.

Seems like a very intersting unit. Can anyone speak to how previous NAD offerings and the Master Class series compared to the Anthem AVM's & "D" series in sound quality.
