Can you bypass the 4 pres on the 002R?

Hey all. I'm about to buy a 002R here pretty soon. But the way my input structure is working out, the only available inputs I have remaining are the 1-4 inputs with the pres. Normally I simply run my vocal booth mic through an outboard mic pre, and then into a single input. But the only remaining inputs are 1-4, and of course, they have mic pres included in them.

For the best input source, I would think that it would be better to simply plug into an input that is not affected by a preamp (on 002R), thus giving a cleaner singal input. So my question is this: Can you bypass the pre on the 002R and simply plug in as a line-level device, right from the output of my outboard mic pre?

Thanks.
