Exactly, and another tip for those using multiple mics..preamps like some of the Aphex ones have mute switch inputs. For the Todd Green setup we incorporated those in a row under the rest of his controls so he can mute/unmute easily with his toes from that controller. rs@moinlabs.de wrote: >Hi Chris, > >yes, you are right, this is a common problem, and Per already said a lot >about this topic, to which I only can agree.
