Adjusting the Head Tension
When adjusting, use the tuning key supplied with the VH-11.
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).

• 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 tuning 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.
