Care Of Microphones - DPA 4003 User Manual

It is important to bear in mind the following points with regards to
mounting, microphone care and the use of accessories:
•
The microphone cartridge is tightly secured to the main body housing,
and no attempt should be made to remove it. If a replacement cartridge
is required, contact your local DPA Microphones representative.
•
Types 4003 and 4006 are supplied with an additional Diffusefield Grid
DD0297 (see "Technical Description" and "Full Specifications"). On
delivery, the normal protection grid is screwed on to the cartridge
housing and normal finger torque is required to remove it. Do not try to
unscrew or tighten the protection grids with any kinds of tools as both
surface and thread might be damaged.
•
Caution: When changing grids, be very careful to avoid any contact
with the diaphragm. Over time a visible dust layer can build up on the
diaphragm. Since the mass added is extremely small and the influence
on the frequency response is negligible, the dust will not change the
characteristics of the microphone. Therefore cleaning the diaphragm is
not necessary and must not be done.
•
Use of windscreen is recommended
when microphones are used in dirty
or dusty environments.
•
When not in use, the microphone
should be disconnected and kept in
the case supplied.
