The rear panel: GUI size along the top, then the setup controls, each with a short note of what it does.

Control	Range	What it does
Input Trim	−24 to +24 dB	Level into OL-2. More in means more levelling and more colour.
Output Trim	−24 to +24 dB	Level after everything else, for staging into the next plugin.
Colour	0 to 100	More warmth and grit, from none to plenty. 0 is the clean, stock sound.
Auto Gain	on · off	Holds your level steady as you turn it up.
Mix	0 to 100%	Blend in the dry signal for parallel levelling.
Stereo Link	linked · dual mono	Level both sides together, or each on its own.
Stereo Balance	−3 to +3 dB	Trim left against right.
Input Calibration	−24 to −10 dBFS	Match your session’s level to where OL-2 sounds best. The default, −18 dBFS, suits most sessions.
HF Emphasis	0 to 100	Levels bright, edgy sounds a little harder. 0 is flat.
GUI size	75 to 200%	The size of the OL-2 window.
