I don't remember- what level is the mackie outputting at? Is it a -10 or +4
output? I'm not sure what is really wrong in your setup, I'm not seeing
anything that is really alarming, that's why I was asking what levels you
are shooting for in ardour, because you may not need more gain. Also,
halfway up is not necessarily bad on yoru channel gain- if you solo the
channel I believe mackie uses that as the prefader level (master level
should reflect the soloed channel level I mean, before the channel fader,
allowing you to set your gain), and that should be around 0 (or U), with
only the occasional higher peak. Then you've set your gain correctly.

computer.
One issue right now -
Levels.
Really low levels.
I'm not sure if, from that, I can determine whether or not I need a
separate mic preamps type device.
Any ideas?
Hopefully it's just a matter of me incorrectly setting levels. :-\ But
if I need a preamp device I'll definitely get one.
When you saw low levels, how low? If you are using a mixer into your
delta
1010 then you have mic preamps. If you are
plugging a mic into your delta
1010 (which I assume you're not- that is only 1/4" inputs, right?, then
those are line inputs and your mic needs amplification. Also, for your
condenser mics you do have phantom power, right? Just checking, without
that
they will not make much, if any, sound.
However, assuming things are working correctly, what level are you
shooting
for? digital 0 and analog 0 are not the same
thing, different scales, so
shooting for 0 on your mackie then shooting for 0 in ardour is not going
to
work- ardour ideally should be peaking around
-18, maybe a hair higher
once
in a while. That is called 0dbfs (0 decibels
below full scale). "Full
scale"
is calibrated to something analog, and -18 is one
standard (people
calibrate
to different things depending on the situation),
so 0dbfs in that case
would
be +18dbv (I think dbv is the scale, maybe dbvu?
doesn't necessarily
matter
though). So if you are recording at +18 analog,
that means your mackie is
red lighting everything, and a mackie most definitely is not going to
sound
good at +18, and your delta 1010 inputs
aren't designed for that either,
so
you're going to get some ugly sound. Just
something to think about, it
may
or may not be your issue.
So when you are gain staging, you want each piece in your signal chain to
operate where it is meant to operate efficiently. In your mixer, if you
max
out your channel gain then lower the fader,
that's not really what you
want
to be doing- the gain is not a "volume
control" really, it is meant to
bring
the operating level of your mic to its correct
spot. Same thing with your
channel faders, you don't want them all up high then the master fader
down.
However, inside ardour, this is different, you
can have your faders up
and
your master down, to a degree. Ardour's
internal headroom is much much
higher than any analog component, so you're not clipping ardour inside,
but
then as you send sound out too loud you're
clipping your converters,
which
can be done with some converters, but not
something on the m-audio level
(me
either, I have a phonic mixer, probably made in
the same factory as the
mackie). So keep your levels conservative and you'll get a better sound.
If there are inaccuracies to what I've said please correct, but for the
most
part I think my info is correct.

Thank you for the info.
I recently posted some info about my current connections/level
settings ("Questions on New Recording Gear" subject).
Here is the bit from that referring to Delta 1010 current settings &
Envy24 levels:
Default button settings on back of Delta 1010 (buttons out, allowing "+4")
Software connections via JACK
Envy24 running, with levels maxed out (ins and outs).
Ardour (no current changes in Ardour's mixer's levels, using default).
