I am planning to do a live recording. I was thinking to use the line output on the FOH mixer. But I was wondering, should I go directly to my converter or should I go through some of my preamps as well?.. I have 6 good preamps (API and Green river). Or will this degrade the sound? (I think the FOH mixer is a Allen&Heat 48chn) I know I would be better to split the signals before they reach the FOH mixer. But I dont have that option.. How would you do it?
