I am 100 % sure that the metering on the compressor device is depressed to +4
My sound interface line out should automatically be at +4
I am going TRS out of MOTU828 to XLR into the compressor unit.
The VU on the device is reading around -7 (this is monitoring on the input meter of the compressor unit)
I am pretty sure MOTU doesn't have -10 +4 switch (it's automatically +4)
