yeah they mixer is just a 32 chan, eurodesk 3282a, dont use it much really just there for routing everything,
I absolutely adore the SE z5600a mic, it has worked wonders mainly on vocals, i havnt had the pleasure of using it as a drum overhead yet, but i highly recommend it, ive even used U87's on certain vocalist and prefer this mic!
As far as the room affecting my mixes, its actually not so bad, since ive had the KRK RP6's my mixes seem to translate pretty well to everything, but i gotta work with what i got...
