  If there's no sound or the sound volume is too low on your Pioneer Music Mixer, several factors could be the reason. First, check if the input selector switch is correctly set to the playback component. Also, verify that the PHONO/LINE input selector is set to the correct component. Ensure all connection cables are properly connected and not loose. Finally, clean any dirty jacks or plugs before reconnecting them.

  Sound distortion on your Pioneer Music Mixer can occur if the master output level is too high. Try adjusting the MASTER LEVEL dial. Also, check if the input level is too high; in that case, adjust the TRIM dial, aiming for the input level to approach 0 dB on the channel level indicator.

  If the BPM can’t be measured or the measured BPM value is incorrect on your Pioneer Music Mixer, it could be due to the input level being too high or too low. Adjust the TRIM dial to correct this. If that doesn't work, the BPM might not be measurable for certain tracks; in that case, manually set the BPM by striking the TAP button.
