Allen & Heath MixWizard and RNC signal too low?

I had a session today where I put a series of backup vocals through the
following chain:
Breathy Male tenor voice - A & H Mixwizard pre with no EQ -direct out
to RNC (3:1, short attack, medium release, 4-8 GR on peaks) - to Apogee
Rosetta 800 48k/24 bit - Digi OO2R ADAT ins. I could not get the
signal in pro tools up to an appropriate level...? I had the Pre
peaking at +6 on the PFL and the RNC's output gain cranked. What
gives? I had no improvement when using the RNC in the insert or with a
Symetrix 501 comp at similar settings. The Pro Tools meter always
stayed in the lowest 25%.
Yes I'm fully aware of the dynamic range of 24 bit and am not trying to
set levels like i'm using a tape machine. Even if I could have seen
levels filling half of the meter I would have been happy. Maybe the
MixWiz' meter is misleading and I should have had the gain higher?
Issue with interfacing balanced and unbalanced gear?
Thanks for any input.

Is there an input sensitivity switch on the Digi interface?

Not for the ADAT ins I think the question is 'Is there an input
sensitivity switch on the Rosetta?'(no there isn't)

 

Did you try adjusting the input gain of the Rosetta? It's not a knob,
it's an internal jumper that sets the sensitivity of the A/D
conversion:

"Analog max levels: +6dBV, +20dBu, +24dBu max (set by internal jumper)"

Obviously the maximum output of the RNC (around +20 dBu as I recall)
isn't tickling the Rosetta hard enough to suit you. Set the jumper to
+20, or to
+6 if you dare.
