I think that's pretty similar to the MPS-1. The MPS-1 toroid looks like 600-700 VA and drives a single channel. The Rotel drives two channels.

350VA is correct for the MPS.

Randy, one of your questions involved possibly disabling the anti-clipping limiter circuit, but as Mojo also pointed out this circuit doesn't cause the amp to shut down, it just lowers the gain. The result is that at extreme levels a lower, more rounded wave top results instead of a clipped flat top. So, that circuit isn't guilty with respect to the shutting down.

Ok, John, Mojo, and whoever wants to provide input, here goes.

I dug out my old digital multimeter. About 15 years ago I took an electronics class through the NRI schools. About all I can remember is watts = volts x amps, if I recall correctly.

So, how about I hook up the multimeter between the speaker terminals on the amp, and the 12AWG wire going to my m80's. Then watch the current (amp) readings as I slowly turn up the volume while listening to music. If I make note of the reading at the time the amps shut down, could I not figure out the watts, and see if I truely am even close to 300 watts?

I just want to be in the ballpark, so when I call Emotiva I've got a little evidence, other than the Radio Shack SPL readings.

Thanks, Randy

Yes, do it, but you'll be reading voltage(which is the boss), not current. Then the form of Ohm's Law which is applicable would be P=Vsquared/R.

Ok, I'm confused, isn't it current that would be traveling through the speaker wires? And, voltage is what would be in the AC line?

Easy on me John.

Randy, the actual power is being carried by way of an electromagnetic wave traveling along the outside(not inside)of the speaker wire. Don't worry about current at this point; the standard way of measuring what you want to learn is by way of taking the voltage across the output terminals at varying levels.

ok, I'm going to run down and give it a quick try...thanks a bunch
