Since I'm thinking of upgrading to the Model 200 M-Block this seems like an appropriate thread to ask this question.

I'm using a Yamaha RX-V995 receiver. There's an "Impedance Selector" switch on the back of this receiver with two position options:

Upper Position
Center speaker - The impedance of the speaker must be 4 ohms or higher. Rear - The impedance of each speaker must be 6 ohms or higher. Main - The impedance of each speaker must be 4 ohms or higher.

OR

Lower Position
Center speaker - The impedance of the speaker must be 8 ohms or higher. Rear - The impedance of each speaker must be 8 ohms or higher. Main - The impedance of each speaker must be 8 ohms or higher.

There's nothing on the back of the Outlaw 200 similar to this switch. Does the 200 not care about the speaker's impedance? I wonder why my receiver needs to be configured according to the speakers impedance and the 200 doesn't?
