Note: If the headband’s standard bend should be too tight, it may be changed for convenience by
carefully expanding the distance between the earhooks. The size as supplied on delivery is more
suitable for smaller heads but may be easily expanded at will.
For the sake of invisibility, you can now choose to bend the microphone boom slightly so that the
capsule is as close to the cheek as possible. This will minimise the risk of shadows on the face,
when used in applications where heavy spots are common. Do not bend by holding on the capsule
itself, but bend the wire boom, making a smooth curve with your thumb to best fit the profile of
the face.
Note: When researching the effect of changes in frequency response of this microphone, tests were
done with the microphone placed directly on the cheek as well as in a short distance away. No
appreciable difference in sound quality is present between the two positions.
3.3 Using MMB4066 separately
Tip: It is possible to use the MMB4066 Miniature Microphone Boom separately, in applications
where the headband is not needed. No electronic components are incorporated in the headband,
which serves purely as a mount to the boom.
In applications where the miniature microphone needs to be invisible e.g. when mounted in hair or
wigs, it can be useful to have a hard steel tube instead of a soft cable running over the head. Also,
when mounted on specific instruments, it can prove necessary to have the microphone lifted from
the base. This is possible when using the MMB4066 Miniature Microphone Boom, because the
microphone element is attached to a hard steel tube.

Note: The capsule features an
omnidirectional transducer and
it is therefore not necessary to
pull the capsule to the front of
the mouth. It can be placed very
discreetly on the cheek and still
produce a highly detailed and
clean sound by using the
specially designed DPA grids.
Please see page 7.
Now take up the 4066 and
adjust the size of the headband
so that it fits the size of your
head: Start with an oversized
headband and use both hands
simultaneously, holding your
index fingers on the back of the
headband while pushing in the
earhook parts inwards with your
thumbs. If you want the position
of the microphone boom to be
altered at this point,
adjustments are still possible,
simply by drawing the boom
while holding a firm grip with
the other hand on the
headband.
