PREFERENCES - MIXER - HEADROOM > set to -13dB or even -9dB (but -13 evens out best)

this evens out all the channel outputs (even for vinyl decks)
I had the same issue, and this solved it.

it does however lower the overall volume for all channels, so you will need to push the volume up on the output (back)... or your amp.

If you want to get a higher output, then you can get something like a dbx goRack to place before the amp.
but really should not be necessary.
