TECHNICAL DESCRIPTION
The cartridge
Types 4003 and 4006 are omnidirectional (pressure) microphones
that use a 16mm diameter prepolarized condenser cartridge. The
diaphragm is a nickel foil which has been coated with an ultra-thin
polymer layer for optimum corrosion resistance. The microphone
housing is of German silver, an alloy with a high content of nickel to
match the stable thermal qualities of the diaphragm. The cartridge
has low self noise (typical 15dB(A) re. 20µPa) and high sensitivity
(4003: 40mV/Pa and 4006: 10mV/Pa). For optimum stability the
microphone cartridges have undergone a special pre-aging process
which stabilizes all tensions in the materials as well as the polariza-
tion voltage.
The preamplifiers
Types 4003 and 4006 are acoustically identical, but differ in their
preamplifier powering system. The 4003 is powered with 130V via
the HMA4000 High-Voltage Microphone Amplifier and has a modi-
fied 4-pin XLR-connector (see Fig. 1 for pin designation). This special
powering system enables the microphone preamplifier to handle
approximately 10dB higher SPL than similar microphone types pow-
ered through conventional P48 systems (4003: 154dB SPL peak
and 4006: 143dB SPL peak).
Furthermore the 4003 together with the HMA4000 is a totally
transformerless system and therefore has an extended low-fre-
quency handling capability (10Hz to 20kHz ± 2dB). The 4006 is pow-
ered via a standard P48 system and is equipped with a standard 3-
pin XLR-connector (see Fig. 2 for pin designation). Types 4003 and
4006 use state of the art low-noise preamplifier technology. The
preamplifiers are driven with unity gain to keep noise as low as pos-
sible.
All microphones come with an individual calibration chart of the self
noise, sensitivity and the individual frequency response.

Important:
The microphone will only operate within it's specifications if
powered correctly.

Acoustic Pressure Equalizers
Available as optional acoustical attachments are also the APEs –
Acoustic Pressure Equalizers. The APEs use diffraction to passively
modify the sound field near the microphone diaphragm, thus
changing the microphone’s frequency response and, in particular,
the polar response (see Fig. 11 and Fig. 12) without adding any elec-
trical noise to the recording. The size and shape of the APE deter-
mines the acoustical changes of the microphone. The APEs are pre-
cision made from a special compact nylon material and will only fit
the Types 4003 and 4006 fitted with the standard Nearfield Grid
DD0251. There are four different APEs in the range: L30B is a
Ø30mm ball-shaped APE marked with a blue dot, L40B is a Ø40mm
ball-shaped APE marked with a green dot, L50B is a Ø50mm ball-
shaped APE marked with a red dot and the L110C is a cylinder-
shaped APE, 110mm long and marked with a yellow dot. The APEs
can be obtained as single units or in two different equalizer kits:
APE L4 contains 4 different APEs and APE L8 contains 2x4 differ-
ent APEs. See Fig. 14 for how to mount the APEs on the micro-
phone.
The Passive Connection Converter
The PCC4000 Passive Connection Converter is an optional accesso-
ry that makes it possible to run High-Voltage Microphones on stan-
dard 48V phantom power with reduced microphone specs. The
maximum reduction of the microphone SPL handling capability will
be 13dB and it is possible to drive up to 100m of cable with the
PCC4000 with the same specifications. Like the High-Voltage
Microphones the PCC4000 is transformerless. The input connector
is a modified 4-pin female XLR for connection directly to the micro-
phone. The output is a standard 3-pin male XLR-connector for con-
nection to standard cables.

The Near-field Grid
The Near-field Grid DD0251 on the microphone cartridge is
designed to have a linear on-axis frequency response for near-field
applications (see Fig. 3 for frequency responses measured with the
Near-field Grid). The grid is factory mounted but can be exchanged
with the DD0297 Diffuse-field Grid or the UA0777 Nose Cone.
Please be extremely careful not to touch the exposed diaphragm
when changing the grids.
The Diffuse-field Grid
The Diffuse-field Grid DD0297 is supplied as standard. It is
designed for diffuse-field recordings, or recordings in the far field.
The grid gives a high-frequency boost on-axis of 6dB around 15kHz
(see Fig. 4) without adding noise to the recording. This boost gives
a linear diffuse-field (far field) response up to 15kHz.
The Nose Cone
The Nose Cone UA0777 is available as an optional accessory . As
with the Diffuse-field Grid DD0297, the Nose Cone is simply
screwed onto the microphone cartridge in place of the Nearfield
Grid DD0251. When fitted, the Nose Cone gives the microphone a
true omnidirectional response even at high frequencies (see Fig. 7)
and a linear diffuse-field response (see Fig. 5). These qualities are
useful at any distance for an even tonal balance of sound arriving
at all angles of incidence, e.g. room reverberation or several sound
sources placed around the microphone. The diaphragm is placed in
a slot behind the solid cone and sound waves only have access to
the diaphragm through the side of the Nose Cone. This way the
Nose Cone prevents an on-axis, high frequency sound pressure
build-up on the microphone, which is the reason for normal flat
fronted omnidirectional microphones becoming more and more
directional for higher frequencies. There is, however, a slight high
frequency boost on axis.

CARE OF MICROPHONE
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 hous-
ing, and no attempt should be made to remove it. If a replacement
cartridge is required, contact your local DPA Microphones represen-
tative.
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 car-
tridge 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.
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.

Fig. 13. Be careful to avoid any contact with the diaphragm.
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 influ-
ence on the frequency response is negligible, the dust will not
change the characteristics of the microphone. Therefore cleaning
the diaphragm is not necessary and should not be attempted.
USE OF ACOUSTIC PRESSURE EQUALIZERS
Acoustic Pressure Equalizers are only to be used with the standard
silver protection grid DD0251.
Do not try to fit APEs on Nose Cone UA0777.
The microphone must be inserted into the APE from the hole oppo-
site to the O-ring. Push the microphone through the hole gently;
apply a small amount of force when the microphone passes the O-
ring and is locked. Never turn the microphone or the APE, since this
may cause a tightening or loosening of the grid. When positioned
correctly, the APE is flush with the diaphragm.
During insertion of the microphone do not place a finger or a palm
across the hole, as air confined in the hole may cause the
diaphragm to crack.
When dismounting the APE, use a thumb to press it off. Never turn
the microphone or the APE.
