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-

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.
