Just got done recording a LIVE session of a classical xmas concert - used a pair of Schoepps MK2s through a Mackie 1642 and tape out to TRS in on MT. Used L setting, gain all the way down with 44.1/16 bit - so I could fit the whole gig on a 2gb card. It sounds great, very quiet and flawless from what I can see on the graph (Peak 4). I run a conservative level on my recordings so it never went above -8 on my Alesis Masterlink, but hit -1.5 on MT. So the input appears to be 6db hotter than line level.
Sounds GREAT!! I'm so glad I used it too, because the Alesis has been writing errored discs on 24->16 conversions and I might just use the MT files instead of mucking around with splitting the files, and making CD24 discs.
Love this machine.sample of MT file below...
