Head Adjustment
The head tension of the KD-120 can be adjusted.
Adjusting the Head Tension
When adjusting, use the included drum key or the drum key for your acoustic drums.
In general, a tension that produces a strike response approximately the same as an
acoustic bass drum will be appropriate.
* Head tension that is too loose may not only cause incorrect operation, but may even damage the
sensor.

1.
Check the current tension of the head.
2.
Remove the kick pedal from the KD-120.
3.
Loosen the lock nuts on the drum bolts.
4.
Adjust bolt ‘a’ in the above diagram. Rotate it clockwise to tighten the head tension, or
slightly counterclockwise to loosen the tension.
* Fully tightening a tuning bolt at only a single location produces uneven tensioning, which may
make it impossible to obtain the proper strike sensitivity and may even result in incorrect
operation. Be sure to tighten each tuning bolt a little at a time, as described in the above
explanation.
5.
Adjust bolt ‘b’ so that the tension is the same as the tension of ‘a’.
6.
Next adjust ‘c’ and ‘d’, and ‘e’ and ‘f’ in the same way.
7.
Make sure that the head tension is even, and repeat steps 5 and 6 if you wish to make
further adjustments.
* On the KD-120, adjusting the head tension affects only the head response, and does not change
the pitch of the sound as it would on an acoustic drum. To adjust the pitch, edit the sound
parameters of the TD-20 or TD-12. For details refer to the respective owner’s manual.
* The head tension will change as the instrument is used, so you should readjust when necessary.
8.
Tighten the lock nuts to prevent loosening of the tuning bolts.
9.
Mount the kick pedal on the KD-120.
