** Since the TDA 8920B is connected "antiphase" at its right and left input, the speakers should also be connected antiphase to
obtain good phase behavior. Follow the connections as above described. Note also that Right + and Left – on Connector 1100 are
interconnected to ground. This is important when measuring on this outputs
