Yamaha 2500 YPAO

I was at my son's house yesterday and he was demonstrating his system consisting of a Yamaha 2500, Infinity mid and fronts (rears not connected yet), and VTF-3R MK2.

Before I arrived, he had trouble with the Yamaha setting his fronts to Large and his crossover to 150Hz. By the time I arrived, he had tinkered with the WYSIWYG interface and constraining the front and mids to small, and the crossover to 80 Hz. When I got there, he ran the YPAO. Using my analog Radio Shack SPL meter and his warble tones disk, we found that the Yamaha had gotten the average levels of the sub and other speakers perfectly balanced. The overall frequency response was +/- 1.5 dB, except for a +7 dB bump at 30 Hz, a corresponding +4 dB bump at 60 Hz, a 3 dB bump at 20 Hz, and a slight dip at 40 Hz. Not a bad result, but I suspect he'll be getting a parametric equalizer to smooth out the bumps.

warpdrive is on a distinguished road
The built-in parametric EQ used by the YPAO on the 2500 only adjusts frequencies as low as 63Hz, it has no effect below that.

Look at page 101 here http://www.yamaha.com/yec/customer/m...s/RX_V2500.pdf
