* IC18_IC has its D1 (pin10) and D2 (pin9) pins floating because of a not-connected via, undetected by Altium (problem might be on previous versions as well!). When activating Ch4 and Ch5 50 Ohm termination, both channels will be electrically connected! Solder a small wire between the via and the neighbouring GND pad.
