If the "REAL dB" you are referring to means dBFS, digital fullscale, that is at + 15.4dB at the M20d's meter.
If you are referreing to the main mix you have to consider that the main mix is recorded post master fader. If you have a level of, for example, +5dB and the master fader is very low, at -40dB, you have a very low level on the recording.
The levels on the M20d'd meters refer to analog dBu. If you see 0dB on the main meter this means that the analog signal at the output is at +4dBu, which is the usual nominal level in pro audio.
dB itself is not an absolute unit for levels. It is a logarithmical scale that needs a reference. The M20d's scale refers to nominal leve 0dB= +4dBu.
The file you are referring to seems to be at 0dBFS, which is digital fullscale. The maximum before clipping. Athe M20d's scale 0dB on the meter = -15.4 dBFS= +4dBu at the analog output.
If you would try to record at 0dBFS everything slightly above that would be clipping. With music this would not work. You can, of course, turn up the levels manually to have less headroom and a hotter recording. The mixer does not automatically change mix levels. Most digital live mixers have their "green" range around - 15 to -20 dBFS. As mentioned before, nothing prevents you from just turning it up and the mixer will not automatically change your mix. The mixer does prevent clipping on the inputs when you use trim tracking but this is automatically made up after the pre amp so there is no change in levels. This also only happens if you are really clipping the input.

I had the same problem of seemingly low recordings. Are you saying we should keep the master record level at around 0 anyway to avoid cliping. I was turning the master all the way up to compensate. Are you saying that will cause distortion.
