The mic preamp is rather noisy *except* at full gain where it is actually quite good, and the normal line in is just an attenuator driving them mic input. It's not too difficult if you can handle a soldering iron without destroying a PCB. You need to remove/replace some components on the front PCB (which is difficult to remove for access, and even more tricky to get back in place, but it's possible). Which ones exactly depends on if you want to use XLR or TRS for input. Mail me off-list if you want the details. Ciao, -- FA
