I just read this thread. It appears that this issue could be very important if I am using a V3 on two channels, and recording the board from the other two, without having the fix done. If I am reading/understanding correctly, one of the two channels is 180 degrees out of phase. Is it as simple as reversing the polarity of one of the V3 channels when mixing, or is there something else that I need to do, until this unit gets the fix? Will I be able to easily see which channel is screwed up when looking at the four waveforms on the computer? Glad I read this before the new machine arrived.
