This feature allows you to change the gain/trim of a channel without affecting the monitor sends / gate / dynamics.
A typical use case would be if an input is louder than during soundcheck and you need to adjust the gain but keep the monitor sound stable.
- Open the config page of the relevant channel
- Press and hold the gain knob (or right-click)
- Enable "Re Gain" from the top menu
- Adjust the gain
Gate and dynamics thresholds will be increased / decreased with the gain value. Sends / Faders will be adjusted in the inverted direction.
