This slider amplifies the output signal with a value after all the processing has finished. This is in effect a volume slider. If the Simple Clipper, Advanced Clipper and/or Hard Limit output is enabled, this value should not be set higher than 0.00 dB (x1.0). Limit Post Amplifier at 0 dB can be set to enforce this. Otherwise, to avoid distortion, make sure that the output bar display is never completely filled: Too loud output means that the sound will be distorted.
