I have been using the Mbox 2 mini for a couple of years and im ready for a new preamp. question is how do i hook up a new preamp properly to protools without using the mbox pres. Ive been told to plug in to the LineIn/DI and keep the channel gain/volume down and it will bypass the mbox pres? others say that that isnt true, that whatever you plug into the mbox uses its pres. ive also been told that i can get an ADA converter to replace the mbox. im not sure what that is or does. any help would be great.
