They still seem incredibly loud though and I'm not sure if this is all correct or if my system isn't set up properly.
Here's iTunes playing a song at full volume:

And here are my CueMix levels:

Note that I have my CueMix Monitor Level set pretty low. The levels don't seem to peak above 24 db, but audibly these levels are pretty loud. I would think that looking at how low the meters are that it should be barely audible. Am I correct or am I missing something? Thanks for any help!
