For your editing pleasure...
I just downloaded a new version of the Yamaha Receiver editor for for my
RX-V1500. Looks like they have V1.1 out now.
Also available is V1.6 for the RX-V2500
It doesn't look like Yamaha has added the Speaker Distance parameters to the 1500 editor...bummer, I was hoping to see it there. I haven't checked to see what else is "new & improved".
