To obtain the best audio results it is recommended to keep always the Wave slider at the maximum level and to use the Master Out to adjust the output level. NOTE: when a full-scale digital signal is played and the Wave slider is at 100%, it is recommended to keep the Master Out slider at about 80%. Otherwise a distortion could occour on the output.
