Up to this point ive only use RME DIGICHECK to check incoming signal level when tracking. I now want to try the spectrum analyzer and metering on it for mastering and mixing. I know that something needs to be done with a Loopback or some shit. Ive done my research but just cant seem to find the work around and when i do it doesnt make sense to me. Can someone in basic steps tell me how to monitor my main outputs with DIGICHECK on a mac. RME FIREFACE 800 Cheers!
