Question When pressing the Side mode, the side channels are combined in mono. Is that normal Answer That's perfectly normal. This feature isn't intended to create an M/S encoder, but to allow monitoring of M and S components separately to check for artifacts (e.g. in lossy data reduction, expanders etc). If it sent both signals, you would not hear what is in the M vs the S parts.
