DPA Microphone DPA 4090, DPA 4091 User's Manual

Introduction

The DPA 4090 and 4091 are discrete and versatile micro­phones characterised by a uniquely natural and open sound.
They can be used with any instrument from electric gui­tar amps to acoustic guitar, piano, saxophone and wind

instruments. Because of their flat frequency response the
4090 and 4091 are excellent choices for calibrating your
sound system.

DPA 4090 and 4091 are omnidirectional (pressure) micro-

phones. To ensure optimal performance of your DPA mi­crophone please follow the simple care and maintenance

instructions below.

Highly resistant materials like gold plated stainless steel,

and features like the double-vent protection system are

used in construction of the microphones, to avoid dam-

age by hostile fluids.

In any case, it is still a good idea to keep the microphones

away from any kind of unnecessary exposure to water and
cleaning fluids and to keep the microphone element dry

at all times.

Care of Microphone

To ensure optimal performance of your DPA Micro­phone, please bear in mind the following points with
regard to mounting, microphone care and the use of
accessories.

The microphone cartridge is 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.

The tip of the 4090 and 4091 microphones is retract­able to provide protection.

Using the windscreen is recommended when the mi­crophone is used in dirty or dusty environments and
when the microphones need to be protected from
wind or pop-noise.

When not in use, the microphone should be kept in
the case supplied.
