One thing some miss is the slider that lies between the tracks and the 'Buss' side of the mixer.

You think you have the tracks up and the main volume up, but that one slider can catch you.
The two main sliders are pointed out in the first image below. These should always be full when doing final wave in RB.

The third arrow shows a plugin in the Final Out slot and how to look at it's reading. Top image is Ozone levels, which are pretty clear.

Bottom image is of an even more informative Level Reporting plugin (many available) that gives me the Peak VU (clip), Average RMS (loudness) and unique P/A reading that shows on average the dynamic range the song has (Peak over Average) .. not the most extreme dynamic range, but the average.

Many ways to measure it, but you need to make sure the final signal is what you want. The Final Output FX slot(s) is best place to do that.

PGPeakLimit comes with the program and can be used as a simple 'raise the volume' plugin in the Final Out slots. It doesn't have as nice a metering view or any other options, but does have a nice simple clean 'make it louder' algorithm.
Set right slider to '0' and push the left slider up to suit.
