Anyone, maybe Crhis, got an idea about settings in the situation mentioned? The R-09 gives 3 volts of plug in power right? Is that enough to get a proper load for full dynamics on the mics? If so, should I set the R-09 to mic gain hi or low? With the preamp, I'd use low and gain up using the pre-amp. Also, since the CA preamp has a hipass filter built in, when not using the preamp would you suggest the lowcut on the R-09?
