Level - volume boost. Unity at full ccw position. Turn it up to make your signal audible with any amount of effect.
Knob Mix - dry/wet balance. Could go up to 100% wet (full cw)
Knob Program - switching between 8 programs.
This unit has one more control. If you press button 10 times in 10 seconds after applying power it will switch input muting. This reverb could be fully muted in bypass and will start making reverberation only after engaging it, or could always listen to input signal and play tails right after pressing a bypass button.
