Bypassing mbox preamps
 

Can anyone tell me once and for all if the focusrite preamps can be bypassed on the original mbox for sure?

I've a nice Avalon 737sp which I'm routing thru a Berinhger mini mixer in the meantime, which in turn goes out to the 1/4 line ins of the neutrix ins 1&2 of my original mbox. So far my ears tell me "no problems", but I wanna make sure that I'm bypassing the mbox preamps.

Of course there are a couple of other threads discussing this matter but I have not read one that answers the question without a doubt.

Digi, can you clarify this for me?
