anyone know the level of gain on the MC stage and the MM stage?

I have a high output MC cartridge (2.7 mv). on the MM settting it doesn't play as loud as I like---it seems to max out around 10:30/11:00 on the volume.

however, when I flipped the switch to the MC setting is is quite loud---I don't need to turn it much past 9:30/10:00 to get it REALLY loud.

am I going to blow out my system running it on MC?
