¿Funny story about that??
We have a large screen home theater with full surround purchased the proceeds of selling my sloop. (When you are forced to stay home because you are now suddenly responsible for 3 grandchildren, you have to do the best you can.) I set it up with a Sony amp with that capability and balanced it by ear the first time and then it do its thing. The automatic was better for a while. Then it started to sound less good. So I ran the automatic again and it was not as good as I remembered. Well, I will admit that my hearing is going the same way as my memory and some less important things....
Then a grand did something foolish and I had to get behind the rack, while there something did not look as I remembered. I got out the wire list and compared. I couldn't figure out how it got that way. But, I knew would probably change things, so I set up the auto-balance again and sat there reading while it hissed its way around the room until..... SHOUT HISS ..... out of the R & RR set. It cranked each of those back to a more common level.
Later I came to find out the GS#3 (known for messing with things that he should not) "accidentally" pulled some speaker wires loose and DS had put them back - he thought - Well, Everyone has been told (again) to not touch and if something happens, tell Papa when it happens.
And people wonder why I never took them sailing.
