The problem is resolved a combination of two things. Unbalanced input and my test equipment ground.
As I am sitting here thinking, I come to the conclusion that no matter how simple or how complex the problem, We always feel like fools not knowing the answer..
As the saying goes; LIVE AND LEARN.
Wish you all a wonderful day !
VERY BIG Thanks!

Look at the schematic! Bridging is done with a resistor and jumper from the ch1 output to the power amp negative feedback on ch2. The XLR input has NOTHING to do with bridging. The ch2 input MUST be unconnected for bridging.
Granted, if you do not set the internal bridging jumper, you could drive ch2 inverted using the XLR inputs.
