Sound is affected by distortion or clipping. Why? DJM-S11 Serato DJ Pro

If the volume level is too high, the sound may be affected by distortion or clipping.
Play a track and follow these steps:

1. Check the channel level indicator on the DJM-S11.
Adjust the level with the [TRIM] knob so the channel level indicator lights up around [0] dB (so the red doesn't light up) at the loudest part of the track.
2. Check the master level indicator on the DJM-S11.
With the channel fader at the top, adjust the level with the [MASTER LEVEL] knob so the master level indicator lights up around [0] dB (so the red doesn't light up) at the loudest part of the track.
3. Turn off the KEY LOCK function by turning off the KEY LOCK button in Serato DJ Pro.

If the distortion and sound clipping doesn’t improve, the output level might exceed the allowed input level of the connected speakers or amplifier.

In this case, you'll need to lower the output level using [MASTER OUT ATT] in the Utility settings.
For details, see the Instruction Manual > [Settings] > [Utility settings].

If sound skipping, sound cutting, or noise occurs, see [Troubleshooting _ Serato DJ Pro] > "Sound skips, cuts, or is affected by noise.".
