I am trying to calibrate my audio setup.
I am using a Maudio410 firewire box as an input to T2. I am feeding a calibration tone into the 410 from my mixing board. I have 2 tracks in T2, one panned hard left and one panned hard right. I have the signal level of the calibration signal set such that the input meters show exactly -6db. I have the trackvol/pan filter set to exatly 0db and the master vol/pan filter set to exactly 0db. Yet the output volume is at 0db???
Shouldn't I have unity gain with everything set to 0db???? Where is the 6db gain coming from?
Gain setup in T2??

Ok I played with it a bit more. It has something to do with the panning law applied. If I leave the pan filter centered on each track and insert a rack that only connects through the right channel on one track, and another that only connects through the left on the other, then I have unity gain through to the output.
Am I just thinking of this wrong or is this really screwy?? (or both??)

there was a lot of discussion about the panning model used by T a while back. I can't remember what the conclusions were.
FWIW, a pan boost is not *that* odd. It ,ay not be standard, but if you are applying any kindo f panning law, then whether it be a panned or a centered signal, something is going to different at unity.
personally, I'd rather have centered be at unity, and panning adding a boost, than to have centered be cut by 6dB.

But how do I use mono input tracks then? If I leave the PAN centered then -6 shows up on both the left and right at the tracks , and the master shows 0db on both left and right. I guess inserting a rack or patchbay filter that chops out the left or right, and leaving the pan centered is an acceptable solution.....

I'm not able to test what Tracktion is doing to pan levels right now, but assuming your observations are correct, and there is nothing else funny going on, I'd say either
a) use a patchbay to lose a channel
b) get in the habit of just doing a straight -6db cut on the the vol/pan of any mono'd track.
c) if you know a given input device will always be used as a mono, maybe you could add a fixed -6dB to the input device

Two more interesting observations (or at least interesting to me)
If I uncheck "treat as a stereo pair" on my FW1+2 input, and try to use them as mono inputs, then I un-check enable EtoE (at the input control box) on one or the other, it disables EtoE on both 1+2.
If I disable EtoE by the master out, the input meters go to 0, the master meters go to 0, but only the meter on the left track track output goes to zero, the right channel meter stays at -6db..

The big meter display is acting very buggy also. I play around with "treat as stereo pair" button and the big meter indication for the right channel will go away and not come back, even though the signal is showing up on the track output meter and the master meter.... The meter in the track property box is showing signal, but the big meter is not.. then I click here and there and it sometimes comes back blah blah blah...
