Thanks Marc, really appreciate your efforts. I hope it works out with Lenbrook. Your app is better than many official ones I've seen for other gear. I really like the sleek UI and it works great every time.

Thanks to @richardsim7 for saving me time going through the docs!

Some other exciting news:

I've been in contact with Lenbrook (the holding of NAD and Bluesound). They're open to exploring cooperating with me so that I can use the official NAD branding. Also, we're exploring on sharing documentation so that I can better support NAD devices that I do not own. I'll keep you guys in the loop on how this progresses.
Somehow my last post got corrupted. This is great news. However, you deserve to be compensated in some form. If they aren't going to pay you, you should reserve the right to charge for the app or at least put a donation on it. We can promote it here so you don't get zapped for promoting your own product without being a forum sponsor.

The cynic in me says a company would love to have someone else develop for them if they don't have to pay for it.

Hey all, I just updated my 758 and now all of a sudden I’m getting loud popping sounds when I turn off the unit. Anybody experiencing anything similar? Literally didn’t change anything, just upgraded the software and now loud popping. I suppose I could do a factory reset?

I don’t have loud popping but I have hiss coming from my speakers which I never had before the latest update. Seems to be something wrong with this update!! Report to NAD as I have so they will correct it sooner than later bud!!!

I've submitted the issue to NAD. Hopefully they'll get back to me The software update fixed a weird electronic noise I was having in my Atmos speakers connected to the AM230 board (or at least seems to so far), so I was happy about that, but this popping is awful.

Now that’s funny cause the hissing I hear since the update is sort of a weird sound. Prior to the update everything was dead silent!!!

Damn!


I have MBP 2010 version which not supported by latest OSX. Till last week I used Diral Live latest version. Last week there were some updates for High Sierra and after that Dirac wont start. At first Dirac thought they figure it out, but just received an update from them



"Hi, There have been some changes in our development framework so that we are not able to support High Sierra in the latest version 2.2.1 and 2.2.2 - we have tried to find a workaround but unfortunately there is no easy way forward. We have seen in some cases that it could work when first installing an older version - however now, when trying the same here, this does not work. So for High Sierra, the Dirac Live version to use would be 2.1.2."

Would be grateful, if someone (the guy in the basement!) who know or figure out workaround, let me know too!


PS. Just had an idea to revert those High Sierra updates from backup! Can't try this till Tuesday myself, away from home.


PSS. Install Windows

Thank you both for the kind words. I really appreciate it.

I don't know what I'll do on the compensation level. I built this driven by intrinsic motivation: I love to build software and I'm able to make people happy by doing so.

However, getting something back for it is always a nice bonus. Getting rich from this, however, is not the intention and also not expected. For compensation, there are 2 possible situations, either I build a free and paid app, in which the paid version has the remote control features. On the other hand, I may be able to strike a deal with Lenbrook. I don't necessarily want to get paid by Lenbrook. I'd be more than happy with receiving some NAD products to be able to test my application with

I actually would prefer keeping it free for end-users and being compensated by Lenbrook. NAD hardware is already in a higher price segment and it deserves companion software to be free.

I have already reported the issue to NAD several times over the last week and they are still looking into the issue. I was just seeing if anyone else is experiencing the same issue?

The 0 dB reference level on a modern AVR when watching a movie will represent an average of 85 dB SPL and a maximum of 105 dB SPL. So we will look at having the capability to reach the maximum of 105 dB.

Note: should you listen at reference levels, please expect some angry neighbors and damaged ears.

For reference, the T758 v3 puts out 110 wpc into 2 channels, and 60 wpc if all channels are driven.

If your speakers are 105 dB sensitive, they produce 105 dB at 1 meter using only 1 watt.
They would need 9 watts to to produce the same level at a typical 3 meter distance.
Therefore to reproduce 105 dB peaks at 3 meters, they would require 1 watt no problem

If your speakers are 95 dB sensitive, they produce 95 dB at 1 meter using only 1 watt.
They would need 9 watts to to produce the same level at a typical 3 meter distance.
Therefore to reproduce 105dB peaks at 3 meters, they would require 90 watts the NAD can do this in stereo, but not with mains and surrounds playing at once

If your speakers are 85 dB sensitive, they produce 85 dB at 1 meter using only 1 watt.
They would need 9 watts to to produce the same level at a typical 3 meter distance.
Therefore to reproduce 105 dB peaks at 3 meters, they would require 900 watts this is clearly not possible

It becomes clear that if you are running 7 channels and you want to run at 0 MV, you can do so with the NAD T758 with most speakers to about 97 dB sensitivity. Below that, you won't have enough power and you will need external amplification.

If you listen at -10 MV, you can do so with speakers to about 88-89 dB sensitivity, all channels driven.

My MLP is 8 feet from my center and 9 feet away from the front left and right. I do have dual subs also.

At this distance with speakers that are 90 dB sensitive (Monitor Audio Gold 350 and 200s) am I even using/taking advantage of my Anthem power amp (170wpc) vs the internals of the NAD for 5.1.4 listening at volumes between -10 and -20 which is about as loud as I go?

Thank you in advance and for the explanation above 🙂

He laid the math out plainly and clearly for you, you just need to put in a little effort yourself.

If 0 on the AVR is 85db avg, 105db max, then assume putting it to -15 is 70db average & 90db max. Your seating is a tad under 3 meters away, which means your 90db speakers are using about 9 watts per channel @ -15 listening, and would take 450watts if you wanted to listen at 0 reference.

So basically at my seated distance if I listen even at -10 or -15 max volume I am kind of wasting my money when I bought my 170wpc all channels drivel anthem power amp as it is not needed or of no added benifit vs the NADs internal 60wpc for driving my front 3?

If that’s the case I’m pretty disappointed but what can I do...kind of a waste for me having it

You need a power amp anyway if you want extra atmos, i got a 7 channel one, not because i needed one. I use it though as , like you say its a waste otherwise.

Your surround speakers are rated at 86dB sensitivity, so -10 to -15 is probably where you max out, going by the numbers. It's probably better using an amp that has a decent amount of headroom left, rather than running near max.

If you frequently listen that loud with those speakers, the amp could be of benefit. But use it for all 7 channels, not just the front 3. Your surrounds are the least efficient and are the ones limiting you to -10 to -15.

The speakers/amp will go louder, just at a different rating of distortion (ie: more)

Hi!

Markus has a Homepage: Mehlau.net

You'll find a possibilitiy to get in touch with him there.
I contacted him already in order to get the presets implemented in his App.
Maybe he gets motivated when there's more users who want to have that finction in the App...

My side surround (MA Gold 100s) are 88 dB sensitivity and and my overheads (MA CT280-IDC) are 90 dB.

Because I have only a 5 channel amp that’s 170wpc I have to drive 1 pair of heights and the rest is the front three.

Therefore the surround (86dB) and 1 pair of heights (90db) is driven by the NAD internal 60 watt amp.

1. Am I causing damage to the surrounds if running the whole system at -10 to -15 with this power?

2. Does it matter that the subs is helping relieve the burden?

3. Would it be a big help in your opinion if I bought a cheap power amp just to drive the 2 heights I have to externally and change the 5 channel anthem amp I have to drive the front three and side surrounds instead of the way I have it?

Sorry about all these questions and many thank in advance...I’m just trying to do my best leanig this stuff 🙂

Ok, major issues after BluOs update. No ARC, annoying beep when using any of optical inputs and no 4K pass through from my Xbox One S. I know 4K issue comes from the T758 cause Xbox works perfectly if connected directly to TV.

Tried factory reset, switched all cables, and no solution. Oppo 103, Apple Tv, Nintendo Switch work fine since they’re not 4K.

Any feedback will be appreciated.

Therefore the surround (86dB) and 1 pair of heights (90db) is driven by the NAD internal 60 watt amp.

1. Am I causing damage to the surrounds if running the whole system at -10 to -15 with this power?
It is highly unlikely. How would that happen by having not enough power? Typically you would damage a speaker by feeding it too much.

They will need fewer watts, but the sensitivity doesn't improve.

Some of us are using a pair of stereo amps for the heights. For the rest, the NAD has quality amplification, so I don't want anyone to take this the wrong way. For me, it's plenty, but I listen at -20 at most.

I would check the distortion specs on the NAD amps and see how they compare. If distortion is higher as you approach -15 to -10 than your other amp, then reducing distortion would give benefits.

If that’️s the case I’️m pretty disappointed but what can I do...kind of a waste for me having it
Your surround speakers are rated at 86dB sensitivity, so -10 to -15 is probably where you max out, going by the numbers. It's probably better using an amp that has a decent amount of headroom left, rather than running near max.

If you frequently listen that loud with those speakers, the amp could be of benefit. But use it for all 7 channels, not just the front 3. Your surrounds are the least efficient and are the ones limiting you to -10 to -15.

Sorry about all these questions and many thank in advance...I’m just trying to do my best leanig this stuff 🙂
If you read the Sound & Vision spec portion of their review of the NAD you will see it actually produces a bit more than the advertised 60 watts. With 5-channels driven at 0.1% THD it actually puts out 86 watts & with all 7-channels driven 66 watts.

Thanks. It would be the 7-channel spec that I'm interested in. Perhaps NAD is rounding down to allow for some sample variability. If so, that is honorable.

86 is very good for 5 channels, too, if the stereo output is 110.

I totally agree bud, especially with a low distortion rating of 0.1%!!!

Thanks for the great response.

Ok, so I get now that in my situation I am not damaging the side surrounds speakers (88 dB sensitivity) listening at -10 to -15 BUT am I maybe clipping or overrunning the NAD amp trying to power those?

It is that reason (the side surrounds without external amplification being the weak link) that makes me wonder if I should buy a cheap two channel amp to power the height pair and let the anthem 5 Chanel also power the sides along with the front 3.

Does this make sense or am I not really needing to in your opinion?

From what I've heard about NAD, they do use conservative power ratings. It makes sense that their amps output a bit more power than advertised, especially in the receiver market. If your reputation is based on being one of the only companies who gives an honest all-channel driven power rating on your product, the perception is far different when a consumer is like "wow, I'm getting even more than what they advertise!" even if it's an small inconsequential amount, compared to if they were off by a little and you're like "oh the numbers are a bit lower than expected, I guess they're like every other major brand, just not as exaggerated!"

It looks like the -15 to -10 area is going to be right about the max for your least sensitive speakers, just based on the numbers. I'd say you shouldn't have a problem with the NAD running 7 channels. You should be able to go to -7 if you reduce to 5 channels and your least sensitive speakers are 88dB (is that if you exclude the 86dB MA 50s?).

I'm curious - what happens when you try to go higher than -5? Do you get more SPL? Is it clean sounding?
