recording going with mics into mixer into delta interface into
computer.
One issue right now -
Levels.
Really low levels.
I've adjusted the levels on the mixer, in the envy24 control, and in
Ardour... and it's like I have to max things out just to get a decent
volume.
What's the trick getting rock solid levels during recording and
playback both without having to max things out? :-\
Since you're using a mixer, the only way to preserve your
sanity is to fix the envy24control gains to some calibrated
value. Normally the 'neutral' setting is 127 for all ADC/DAC
controls - this should produce equal input and output levels
but how much this is true will depend on your soundcard design.
For the ADCs, the part above 127 actually controls a separate
preamp stage which you normally should not use for line level
inputs. Select +4dBm or not depending on what your mixer expects
and produces.
First calibrate the playback part by playing e.g. some ripped CD
tracks in Ardour, and adjusting the mixer/soundcard gains and
the final volume control. Once this is OK, don't touch anything
on the playback part (except maybe your final volume), and then
adjust inputs. If you don't have enough gain for some instruments,
you'll need DI boxes or preamps.
