DVD playback thru Control24 calibrating?

[Hype]

I'm hooking up a BlueRay DVD player to the External sources discrete 5.1 inputs on the Control24 and everything comes through fine except the BlueRay player is outputting a consumer level -10 signal. So I was wondering if there is a way to calibrate the Control24 inputs to accept a -10 level, since that's what it's getting, insted of a +4 level.

Right now I have to crank the monitor output up to full level to get any decent volume out of the monitors. Is this something that is possible or should I just live with the low level I'm getting?

Any help would be appreciated, Thanks.
