Possibility to Calibrate Audio Output Levels MXO2

Can you please add a functionality to calibrate the analog (XLR) audio levels from the MXO2?
At the moment my MXO2-Max is outputting a -18 dBFs reference level from FCP +7 dB higher at -11 dBFs.
It would be great to have a slider (or a numeric input box) possibly in combination with a calibrated digital peakmeter (dbFs scale) in the MXO control panel. It would be completely perfect if you can also calibrate the XLR inputs.

Regards,

Yeah, I really need to calibrate my levels coming and coming out of the XLRs. Right now they aren't even close to where I need them.

I'd add that the real issue here would seem to be that the levels shouldn't need calibrating ... if a -18 dBFs level is coming out of any of the different outputs at anything other than -18 dBFs then it's a bug that should be fixed.
Any extra control is a good thing as far as I can see so I vote yes ... but it shouldn't be necessary for general calibration purposes.

Re the issue as is, just a thought, but have you checked you application audio assignments to ensure that you are not inadvertently doubling up levels; similarly the MXO2 preference pane Audio Output assignments.

Same problem. Levels are far too low and we cannot do anything to override them. I really hate having to increase the volume in post.

Reference level calibration options are important. All our audio interfaces have it. I sound like a broken record, but the audio side of the MXO/MXO2 product line needs a lot of improvement to be a proper stand alone unit in small-shop post workflows (IE workflows that assume their I/O device doesn't require a second, and expensive, audio interface.)

Matrox should take a look at the options available on most audio interfaces. RME, Apogee, Motu, Echo Audio just to name a small (but wide) segment of the market. We need reference level control and sample rate control for starters.

Core Audio was a start. Next, get it to work. Following that see above.

Great thread!

(I continue to think it borderline false-advertising to call the audio side of the MXO2 product line "professional." Sure you could get away with the face that it has XLR connections - but the Cannon connectors is where professional seems to end.)
