The Twin Boost has 2 independent gain stages which can be set to work together (JOINT) or individually (SEPARATE).
Essentially there are 3 modes of operation:
1)
JOINT +
PRESETs: channels always have the same gain and it's possible to save and recall presets.
2)
JOINT + GAIN
STEP: channels always have the same gain which is handled with GAIN STEP function.
3)
SEPARATE +
PRESETs: gain of channels can be set individually and it's possible to save and recall presets.
