Looking at the 1010LT manual, I see that the jumpers are only for the
two XLR connectors to set them Mic (-50ish) or line (+4). The manual
then say that the i/o level can be set in the control panel
(windows/OSx) to line, consumer or -10... that is +4, -4 or -10. I
see that mudita24 does not have these settings and so would assume
0db = +4db out... which is definately too much for anything that
likes to connect to the RCA jacks the LT comes with. You should
probably be running your DAC levels at -12 or -14 if you are using
-10 amplification for monitoring.
Thanks for the comment. This aspect is very interesting. The only
Pro/Consumer settings are seemingly for S/PDIF configuration.
The monitor setting in Ardour is at 0.0dB. This way I figured what is
heard is what the master bus fader is at, and not adding any other
amplitude modification. Since it is likely that the DAC is set at
+4dB, wouldn't this mean that a 1010LT fader compensation of -4dB would
be sufficient to bring the default out at 0dB ?
:) It depends on what your audio equipment after the 1010LT is looking
for. Most anything with RCA inputs thinks that -10db actual level is it's
version of 0db. Most profesional equipment (balanced inputs) thinks of
+4db as it's 0db (often having headroom up to around +30db). So if you are
going rca out to rca in, you should assume it is "looking for" -10db which
means setting your DAC level to -14db.
The consumer/pro in s/pdif is not levels, but dictates what the extra
s/pdif information it sends looks like. Consumer is s/pdif and "pro" is
AES3.
