Hi everybody,
I have a M-Audio Delta 1010LT and use 64Studio 3.0 Beta. Basically
everything works fine, but I have two questions, regarding the
envy24control:
My 1010LT manual states, that the output level of my soundcard can be
set through envy24control to different levels: +4dBu, Consumer, and
-10dBV. However, these buttons are missing in envy24control. Is it
possible to set these levels with envy24control? The same question has
already been posted two years ago
(http://www.nabble.com/Delta-1010LT-Variable-Input---Output-levels--tp129199…),
but did not receive a reply. Also some forum mention a IPGA analog volume, which I cannot
find in envy24control (see
http://www.nabble.com/alsa-and-delta-1010lt-trouble-td10379972.html).
My second question is about the range of the faders. I want to record
music via a mic, which is connected to a preamp which is in turn
connected to the XLR1 input. The Fader responsible in envy24control is
ADC0, and has a range from 0 to 163. What does this range mean? Is it
just attenuation? Which would be the optimal setting in terms of keeping
noise low (I can set the output of my mic-preamp accordingly)?
Thank you for your help,
Markus

Hi Markus,
well, I'm using the 1010LT as well and to change the levels
between +4, Consumer, -10 you do this on the 5th tab 'Analog Volume'.
To have a better idea of how the levels are 'really' set in terms of
db, I use 'alsamixer' on the terminal, which indicates levels in db
instead of numbers that I can't interpret correctly. In case you have
more than one sound device, use i.e.: alsamixer -c1(or 2/3/4)
I try to get a signal as hot as possible, but without clipping, in to the
box, and then I can adjust my output volume (which serves me mainly
for monitoring anyway) according to my needs. I know this is not really
a professional approach maybe, but it works for me.
HTH,
Raphael ;)

Hi Raphael,
Thank you very much for your answer. Do you mean, that you can change the
levels via the adc faders? Because I cannot find a switch +4 or -10 in the
5th tab. And thank you for your tip with the alsamixer. It shows me, that
for the adc fader in envy24control set to 124, I have 0 gain. Alsamixer says
that it can change the volume between + 18 db and -62 db, can we trust these
values? Still, the range from 0 to 163 in envy24control seems strange to
me...
In terms of sound quality, is it bad to amplify the input signal via the
Delta1010lt (with adc set higher than 124)?
Thanks for your help,
Markus

Yes, the gain-staging is via those faders, since there's no 'switch' in the
linux control panel for the envy24-based cards.
Even in the Windows version, although you can find a switch to determine
+4, Consumer or -10, these are just faders as well. The so called 'switch'
just makes the faders jump to a predefined fader value. So you can still
finetune those settings. And btw, IIRC the +4/-10 switch only works for the
first input pair (XLR). But I'm not sure about this, I'd have to search
the manual to be sure.
And thank you for your tip with the alsamixer. It shows
me, that
for the adc fader in envy24control set to 124, I have 0 gain. Alsamixer says

I never really understood the values/ranges in the envy24control panel.
The one which has me the most puzzled is the 'Volume Change Rate' in the
'Hardware Settings' tab.
In terms of sound quality, is it bad to amplify the
input signal via the
Delta1010lt (with adc set higher than 124)?
IIRC, 0db on the control panel is always '0dbFS (Full Scale)', which doesn't
correspond to 0db VU in the analog domain. So there's absolutely no need to
go exactly (or even too near) 0db. Leave yourself a little headroom so that
you're still able to process your audio after the recording process.
Digital clipping really sounds nasty to my ears. You can hear it more
and more often in audio files downloaded from the net, and even on newer CD
releases sometimes.
But there are people on this list (Fons, Paul Davis, Norval, Dave Phillips, Ken
Restivo and many, many others) which can surely give you better replies and/or
scientific explanations on the subject.
Thanks for your help,
Markus

I'm very flattered - gobsmacked even - to be included in such illustrious company, but
it's like including me in the leading team for the Tour de France - I'm not quite
ready yet!
Thanks for making my day :)

Edit: Been sending this to Norval instead of to the list, so here
it is once again. This gets me so often, the reply mode to ml's.
Why doesn't it reply to the lists as default?
-----------------------------------------------------------------
Well, I'm a long time lurker, rare poster Norval.
And you definitely are one of those that generally know what they're
talking about. And I have forgotten/accidentally omitted a large number
of capable guys in the list. Mea Culpa. It's not been 'cause of my evilness.
:D

Huge inertia. Google for "Reply-to munging considered harmful". ;-)

Ouch. Didn't fail it's effect, although that 'lmgtfy' thingie
is really funny.
Thank you sir (I'm sooo tired, I'd better go to sleep) :D
