MASTER OUTPUT GAIN: 0.0 to �infinity. Default: 0.0dB. The Master Gain control will affect the total Doubler output, including the direct path. When there is a generally good-sounding setup that occasionally clips the output, you can adjust the gain in order to eliminate clipping. OUTPUT METERS show the plug-in output and under the meters there are peak counters. These counters will show the peak value until reset by clicking on the meter or counter. CLIP LIGHT lights in red whenever output clipping occurred. Lower the output gain to avoid clipping. Click it to Reset.
