About the Mesh Head
Adjusting the Head Tension
• On the KD-80, PD-80R, and PD-80, 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.
• The head tension will change as the instrument is used,
so you should readjust when necessary.
• The head stretches when used for extended periods, so
even when properly adjusted to 7.5 mm (KD-80), or 7 mm
(PD-80R and PD-80) by means of the following
procedure, you may not achieve the same degree of
tension as when the head was initially adjusted. Strike
the head to check the feel and response as you adjust the
tension.
• Tighten each tuning bolt one by one, observing the
numerical order shown in the diagram.
Do not firmly tighten a single tuning bolt by itself. Doing
so will make it impossible to tension the head evenly, and
will cause malfunctions.

1. Use the included tuning key to tighten the tuning
bolts.
Tighten the bolts until you achieve the correct amount of
space between the frame and the hoop, which is:
KD-80: approximately 7.5 mm
PD-80R/PD-80: approximately 7 mm
Black strips, one 7.5 mm in length and the other 7 mm,
are printed at the edge of this page. Use these for
reference when making the adjustment.
2. Fine-tune the adjustment while continuing to check
the pad feel and response.
The KD-80, PD-80R, and PD-80 are shipped
from the factory with the head tension
loosened. Be sure to adjust the tension
before use.
In general, a tension that produces a strike response
approximately the same as an acoustic drum will be
appropriate.
• Striking the head when the head tension is loose
may damage the sensor and head.
• Should you neglect to make the appropriate
settings, you could likely experience the
following problems:
Sometimes it does not sound (uneven volume).
The volume is too low (reduced sensitivity).
