The first thing you need to know is what the controls
actually control.

I've never used a 1010lt, but in order to provide some solid
info rather than guesses to the OP of this thread, I've been
reading the manual. Some of it is informative, most of it is
the usual blabla. The 1010lt has 8 analog inputs. Two of them
have mic preamps, which can be configured for different gains
by jumpers on the PCB. Then there are 'input level' controls
in the mixer app. Not just the usual -10dB/+4dB switches, but
even real faders. Even after reading all of the manual, it's
a perfect mistery what those are actually controlling - analog
gain before the AD converter, or some scaling in the digital
domain. If I had the card I could easily find out in a few
minutes. But without the HW one can only guess.

Combining the tube preamp and the 1010lt, there are at least
four points were gains can be set between the mic and the SW.
Usually two of them is enough to confuse a non-technical
