I was trying a few things with my A700 today and among other things I tried running one of my 9444 without the 1632a on the 515. Strangely the phase was now incorrect and I didn't understand a thing. I reversed on one channel and everything was OK. Connected the 1632a XO again and as I thought the phase was againg wrong, so I changed back and everything was back to normal.

Is this normal behaviour of 1632a or is there anything wrong with mine?
