thanx guys,

in all the reviews I've read about the empath, people said that the auto gain control generated too much compression and that they actualy didn't use it. In fact I havn't really understood what it was used for...

The djm serie looks nice but i don't need four buses as on the 600 and I don't really want effects as well, I'me quite old-skool, mixing properly good tracks is enough for me, so I prefer a simple 2 (or 3) buses unit but with really strong sound and precision, that's why I was going on the ranes.
Did one of you try the ttm56s?

cheers
:)
