Troubleshooting
Reference
Some problems may be solved by restoring the default settings (Factory Reset). If the following
instructions do not work, we recommend the Factory Reset (See page 22).
No sound is produced when a pad is struck, or the volume is lower than expected.
 Check connections as follows.
• Ensure that the pads are properly connected to the drum module's trigger input jacks.
• Ensure that headphones or speaker are properly connected to the [PHONES/OUTPUT] jack (not the [AUX IN]
jack) on the drum module.
• Ensure that the amplifier and/or speakers connected to the drum module are turned on and are not set to the low-
est possible volume.
• If you are using a KP65 Kick Pad, try adjusting its Level dial.
• Ensure that the cables you are using are in good condition.
For DTX402K
•
Ensure that an HH40 Hi-hat Controller is properly connected to the [HI-HAT CTL] jack and a KU100 Kick Unit is
connected to the [KICK/PAD] jack on the drum module (page 57).
 Check the drum module's settings as follows.
• Ensure that the drum module's volume is not turned fully down. Also when directly inputting the volume with
numerical values by using the number buttons, try pressing the number buttons in rapid succession. (See page
41)
• Adjust the following parameters from Menu Mode.
- Pad Volume (See page 43)
- Gain (See page 50)
- Pad Velocity Curve (See page 48)
- Crosstalk (See page 49)
- Snare Pad Type (See page 49)
- Pedal Type (See page 50)
- Local Control (See page 45)
 If kick sounds are not produces as expected, try the following.
• Low notes may not be produced depending on the particular headphones you are using. If necessary, try different
headphones.
For DTX402K
•
If you are using a KU100 Kick Unit, connect an HH40 hi-hat controller before turning on the drum module. Please
do not turn the drum module on with the HH40 depressed. The drum module cannot identify the type of pedal
properly and it causes that the kick may produce much smaller sound than expected.
 If you cannot play foot closed hi-hat sounds, try the following.
• Ensure that you are operating the hi-hat controller in a firm and full manner.
• Ensure that the Double Bass Drum parameter from Menu Mode is set to "Off" . (See page 44)
• If you are using an HH65 Hi-hat Controller, set the Foot Close Position parameter from Menu Mode to a small
value. (See page 46)
