Introduction; Placement; Cleaning Guide - DPA 4088-F User Manual

INTRODUCTION

To ensure optimal performance of your
4088, please follow the simple instructions
of care, maintenance, and mounting below.
The Cardioid Headband 4088 from DPA is
designed to be very resistant to humidity,
moisture and sweat. Highly resistant mate-
rials are used in construction of the micro-
phones, to avoid damage by hostile fluids.
In any case, it is still a good idea to keep the
4088 microphone away from any kind of
cleaning, unnecessary exposure to water
and cleaning fluids, and to keep the micro-
phone element dry at all times.
Keep dry

PLACEMENT

In general, to ensure the optimal sound of
the 4088, it must be mounted at about
2-3 cm (1 inch) from the corner of the
mouth. Correct placement ensures that
you avoid air noises from the nose and
mouth from being captured by the micro-
4
phone. Avoid any contact with beards or
moustaches. Please note that the 4088 is
not designed for placement directly in front
of the mouth. The sound timbre and pressure
is as good at the corner of the mouth as it
is directly in front of it. See the pictures below.

CLEANING GUIDE

When mounting the 4088 on a performer,
care should be taken to avoid sweat from
running directly into the microphone. If the
microphone gets filled up with water or sweat
it will possibly turn deaf while the water is
captured inside the microphone, behind the
fixed protection grid.

the capsule by running down the boom.
Care of the microphone element
The microphone diaphragm is protected
inside the microphone housing and there is
no access to the diaphragm. It is well pro-
tected from dust build-up and no attempt
should be made to remove the protection
grids to clean the diaphragm. The protec-
tion grids are not removable, therefore no
attempt should be made to clean the grid
surface and extreme care should be taken
not to clog the grids with make-up or other
such substances.
If water or sweat has entered the micro-
phone element, remove it by shaking the
microphone gently. When it is left to dry out
it will recover to its original specifications.
Drying out the 4088 between exposures to
humidity will also help to extend its lifetime.
Do not use any kind of cleaning fluid. Use of
ultra-sonic baths must be avoided. Avoid all
kinds of spray or fluids, which contain
chemical components to remove static
electricity on or close to the microphone as
this could cause damage to the electret layer.
Cleaning the microphone cable
Residue from tape, glue or make-up on the
cable must be removed after use. Leaving
these substances on the cable over longer
periods of time may etch into the cable
jacket and will make the cable more suscep-
tible to breaks. The cable can easily be
cleaned using organic oil (e.g. olive oil) or
lukewarm, distilled water. Do not bend the
cable or rub it harshly since this may stress
the inner cores of the cable and cause
them to break over time.
