Routing:
Line output (analogue) from Presonus 1810c to UCS222 ADC to Audacity on MiniMac 2020 (OSX 13.4).
The signal comes into Audacity about 6 dB too hot. The recording level slider won’t move, or, if it moves, has no effect on the amplitude. Sometimes it jumps back to 0 dB. This seems to be inconsistent.
And even weirder: lowering the output of the 1810c has no effect either.
Contacted Behringer about it - they have no idea what causes this.
