I am trying, and failing, to understand how my convolution based setup relates to a "normal" (bd player + av processor) setup with respect to output levels.
For example lets say I have to have my processor at -5 (this is just an example not a real value) to get 75dB on the jriver test tones. If I then want to listen at reference, at what level would the processor have to be assuming all other steps in the chain remain at the same levels?
For the sake of keeping the discussion simple, assume I can measure 75dB perfectly at the listening position using the test tone (i.e. any discussion about the nature of pink noise and in room variations through that band are simplified away).
EDIT: I think I had search failure earlier as I have now found http://wiki.jriver.com/index.php/Volume#Reference_Level_Calibration and this says to get it to 83dB for reference. Does this mean I'd have to have the processor at about +3 for reference?

I'm not sure I fully understand your question; but if the JRiver test tones measure 83 dB at your listening position, you're at reference calibration (whatever your processor says). The test tones are -20dBFS pink noise, so if you measure 83 dB while playing them, things are calibrated correctly.
If (using the same tones) you previously measured 75dB, you might be able to just increase the processor's volume setting by 8dB, but it's probably worth measuring again to make sure your processor isn't doing something unusual.
Or are you asking something different?

Are you going to use internal volume in JRiver or your processor to control volume?

my processor (as I don't have the PC hooked up to my remote yet)
this means everything (jriver, mixer app) on the PC is at 100%

I think you've interpreted my confusion correctly :)
FWIW it seems awfully loud if I set the processor such that the tones are at 83dB. I've listened at reference on occasion and obviously it's loud but this was *really* loud. I realise this isn't especially scientific ....
