Automatic speaker calibration
Yamaha's Parametric Room Acoustic Optimizer (YPAO) automatic speaker calibration system determines speaker sizes and volume levels, measures the distances from the speakers to the listener, sets the ideal subwoofer to speaker crossover point, and confirms that all of the speaker cables are correctly hooked up.
That's pretty standard stuff for receivers, but we think Yamaha's YPAO is one of the easiest auto setups to use. Plug in the (supplied) Optimizer microphone and make your way through the RX-V667's great-looking and nicely organized GUI menus. Once you're on the Auto Setup menu, just press the "Start" button and the YPAO will send a short series of test tones to all the speakers and subwoofer.
