cbit said: "Everything is at unity gain except the main output from my mixer (monitor gain). The guides say (if ive understod them correctly) that the idea is to play a -20dBfs signal from your daw (ie. a signal that leaves 20dB of headroom inside the daw) and adjust your monitor gain so that that level in the room reaches 83dBSPL per speaker at the listening position. This means that at your listening position you can monitor sound at a good level (83dBSPL, or 77dBSPL per speaker) while still having enough headroom to not have to worry about overs-- or rather if you get an over, you'll know about it because it will be obscenely loud!"
