Ok guys here is my setup Alesis 32 Mixer, Motu 828 into my DAW. the 828 has gain knobs for all channels, but when I use these in conjunction with the trim knobs on the mixer I get alot of noise. Should I just use the mixer pre-amps and not the MOTU's. It gets even more confusing when I am transfering my bands practice sessions from our tascam 4-track > mixer > 828 > PC. DO I have too many things in my chain? should I just by-pass the mixer?
