TOPIC: NANODIGI 2*8 master volume tuning or control

Hi,
I am trying to upgrade the nanodigi 2*8 firmware... Never sure it is doing it.... from the user download page you write the new version from june 2018 is 2.02 but the board calls it 2.2....
my question is what is "alexa" ? or is there a way to change the master volume without remote ?
could you update the usermanual so it integrates the auto (????!!) thingy and the IP adress square.... at some point....

cheers mate,
and for the master volume control , any mean to change it without the remote control ? it s been more than a year i haven t used this unit can't remember...

I'm surprised you're not using it. The nanoDIGI unit is probably the coolest product in the miniDSP line.

Regarding the volume control, I don't use it. I find it too cumbersome.
But, unless a user is just plugging the S/PDIF output of a CD player into the input, there isn't really any need to. I suspect most users now have the capability to control volume digitally in their upstream source somewhere.
I use a Raspberry Pi unit with IQaudio Pi-Digi+ running Volumio.

The firmware update is for Alexa and IP control via the WiDG as correctly highlighted by Dave.
- Here is an app note on how to control via ALEXA: www.minidsp.com/applications/advanced-tools/alexa-voice-control using the WIDG
- We do plan to release an update to our current Android/Iphone apps to control all products over the WIDG. That could be an alternative.

hi,
i stopped cause i was sick and tired of having nothing coming out of my speaker when wanting to listen to sweet music, because of the damned nanodigi came off at some point.... so if you do not have computer connected to it you have to replug the computer make them communicate, check you are in the right config (re synchonize) and cross your thingers it won't do it again ! which it did ! so I gave up mini DSP and went straight to audio architect which works flawlessly....
Why did i touched the volume control ? indeed i tried (in the past) to bi amp, having only one conversion (not two, like with audio architect) so two dacs and two amps, using the nanodigi as a preamp.... my streamer having no volume control...
now I use it as a room corrector only and indeed i do not have to touch the volume control set to 0...
but when i replugged it hte other day, it was set to - 24dB from last use (in bi amp), so i had to buy a remote controle just to put it back at 0 ...
as i said pain in the ass these little things

another thing dreite,

could you please explain to me why one has to set a -10db at the imput of the nanodigi2*8 so the unit doesn't saturate ?
(it s not like an analog input being too high like 4 V or 6V since it is all digital .....)

this is a big drawback aswell as one looses 10dB of dynamics having to compensate for it later in the chain.....

If you need to set the input to -10db, then you must have EQ in the unit programmed in excess of +10db. With no EQ set above 0db, it should be impossible to clip the outputs.

That said, if you're using the unit as a crossover, various crossover applications will increase the crest factor of the signal and might cause slight clipping. But a simple 2-3db attenuation would solve that. -10db would be way in excess of any requirement.

Dave.

nope sir, I had to set this -10dB before entering any equalisation as the meters are going to the top of the red.... and afterwards, none of my equilisation has a +10dB ...over the 5 peq one speaker has a +6 dB, the other one has two +5 dB the remainings being in minus....
one again before the nanodigi I have a simple streamer, being a moon MIND180 with no volume or any tuning possibilities whatsoever....
oh well doesn't matter ! thaks anyway for your king help!
have a nice day

Send that nanoDIGI to me. I'll put it to good use.

Dave.

not sure what you mean.... do you want to fix it for me ? or do you tell me i do not know how to use it and that i shall give it to you ?

and about the -10dB at the input i just remembered having the same discussion and the devteam confirmed i was right in doing so more than 2 years ago.... here is the dialog we had at the time: (two las posts)

I think you've misinterpreted what Devteam said. It's the same thing I did.

Let me try again: If you have a composite equalization inside the nanoDIGI unit of +Xdb, then you would need to attenuate the inputs -Xdb to prevent clipping in all cases.
The worst case would be.....where your volume control is set at 0db and you have program material content at 0dbFS at/near the frequencies you boosted with EQ.

Also for reference, the graphical indicators are somewhat conservative. Even though they might peak up to "0" indications occasionally, that doesn't necessarily mean the unit is clipping/saturating. You would need a oscilloscope to confirm.

You can trust that I'm correct on this stuff. I have as much user experience with the nanoDIGI unit as anyone.

Dave.

so when they write " -10dB on the input RMS is about right" it means keep them at 0dB....

I got it ! cristal clear!

for ma general culture, where are you from dave dreite ?

@jahjahlove

Unfortunately at this stage, we're a bit unsure of the situation. What do you mean exactly by the above?

"so when they write " -10dB on the input RMS is about right" it means keep them at 0dB...."

As for ourselves, we meant the following:
- RMS monitor is the INPUTS signal. It has little to do with the fader level.(what Dave refers to).
- -10dBFS headroom on the RMS monitor is indeed a good enough headroom for your input signal..

There seems to be some confusion I guess.. Maybe send us some screenshots of what you're seeing while being live and connected to your unit? If you state that the RMS monitor input level is in the red, that's an issue. Please share your XML config file as well. File - > Save and zip the file to share as attachment.
