2 Correct use of the Miniature Microphone
It is important to observe the following guidelines concerning the daily use of the microphone.
2.1 Correct use of microphone grids
The two different protection grids that are supplied with the Miniature Microphones Type 4060, 4061,
4062 and Adjustable Miniature Microphone Headband Type 4066 are for acoustical equalization,
according to the placement on the body of the performer. When mounted on the head of the performer,
the microphone normally needs a 3 dB soft boost at 8-20 kHz, provided by the soft boost grid
(position A). Placements on the chest or near the ear of the performer require a 10 dB boost at 12 kHz
for the microphone to sound natural (position B). This acoustical equalizaion is noiseless and is
provided by the high boost grid. Type 4065 Miniature Microphone Headband is only supplied with the
soft boost grid as the microphone will always be placed near the mouth.
Attention: Avoid excessive force or tampering when removing or mounting the grid, as it may
cause damages to the grid and the net in top of the grid may become detached.
Note: The microphone is supplied with the soft boost grid fitted. This grid must be removed before
being replaced by the high boost grid.

1.3 Cleaning the microphone element
The microphone diaphragm is protected inside the microphone element housing and access to the
diaphragm is via a perforated grid only. The element is therefore well protected from any dust or
other dry particles building up on the diaphragm. Dust on the microphone element should be left
alone and no attempt to clean the element should be made. The only recommended method to
clean the microphone element is to use a dry cotton bud. Clean (or wipe) the sides of the element
facing away from the perforated protection grid only.
Attention: Cleaning the microphone element by routine must be avoided. If the microphone is fully
functional do not clean it. Avoid cleaning of the microphone element as long as possible.
Attention: Do not clean the microphone element with any mechanical object other than a dry
cotton bud.
Attention: In case of particles clogging up the perforated grid in the microphone element contact
your nearest DPA Microphones representative for advice.
