When adjusting, use the drum key supplied with the VH-11.
• On the PD-85, 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.
1.
Use the drum key supplied with the VH-11 to
tighten the tuning bolts.
Tighten the bolts to keep the space even all around between
the frame and the hoop.
* The setup includes a lock bushing (to prevent loosening), so
the bolt should be tightened fairly securely.
fig.PD-85-Head1.e
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 such as failure to accurately
detect the striking location.

2.
Tension the head evenly while checking the feel of
striking the pad.
Normally, it would be appropriate if the tension is the same
as an acoustic drum.

Be sure to adjust the head 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).
Keep the space
even all around.
