is there any way to calculate the number of watts currently 'in use' by the receiver. Having 200w capable speakers (m22ti), is it possible to find out how much power they are using at a specific volume level on the amp (like -10db)?

I'm wondering how to figure if my AVR has breathing room, regarding power output.

is rated 130w at 1khz and 110w/ch for 20-20khz
