4006A Omnidirectional Microphone Quick Start Guide

4006A Omnidirectional Microphone
A combination of the MMC4006 Microphone Capsule and the MMP-A
preamplifier, this mic is part of DPA’s recording microphone series.
Attenuation Pad
The MMP-A preamplifier has a 20dB attenuation push-
switch at the XLR connector. Use a pencil or the like to
activate the attenuator and lower the output by 20 dB.
Grids
The 4006A is supplied with three dierent grids that are used to change
the characteristics of the microphone acoustically. Be extremely careful not
to touch the exposed diaphragm when switching grids. Do not attempt
to remove dust. The performance of the microphone is not aected
by dust.

The pre-mounted silver near-field grid (DD0251) exhibits neutral frequency
response when used in near sound field (direct sound field).
The black diuse-field grid (DD0297) oers recording accuracy in diuse
sound field (far field) by compensating for the natural high frequency loss caused by air absorption.
The silver trapezoid close-mic grid (DD0254) subtly rolls o the highest frequencies
to create a smoother treble response when close miking sources with bright transient impulses.
