TECHNICAL DESCRIPTION
The cartridge
Types 4003 and 4006 are omnidirectional (pressure) microphones that
use a 16 mm diameter prepolarized condenser cartridge. The cartridge
has low self noise (typical 15 dB(A) re. 20 µPa) and high sensitivity (4003:
40 mV/Pa, 4006-TL: 35 mV/Pa and 4006: 10 mV/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 polarization voltage.
The preamplifiers
Types 4003, 4006 and 4006-TL are acoustically identical, but differ in
their preamplifier powering system.
The 4003 is powered with 130 V via the HMA5000 High-Voltage
Microphone Amplifier and has a modified 4-pin XLR-connector (see
Fig. 1 for pin designation). This special powering system enables the
microphone preamplifier to handle approximately 10 dB higher SPL
than similar microphone types powered through conventional P48
systems (4003: 154 dB SPL peak and 4006: 143 dB SPL peak).
Furthermore, the 4003 together with the HMA5000 is a totally trans-
formerless system and therefore has an extended low-frequency
handling capability (10 Hz to 20 kHz ± 2 dB).
The 4006 is powered 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 possible.
The 4006-TL is equipped with a state-of-the-art transformerless pream-
plifier. All components in this construction are very carefully selected to
fulfil the demand for optimal neutral timbre, relaxed purity, tight and
focused imaging and extremely low distortion even at very high sound
pressure levels. The transformerless design has an extended low-fre-
quency handling capability (10 Hz to 20 kHz ±2 dB). The 4006-TL is pow-
ered via a standard 48 V Phantom Power supply and has a standard 3-
pin XLR connector. See Fig. 3 for pin designation. The output is impedance
balanced between pin 2 and pin 3, with pin 2 carrying the signal.
An attenuator is applied in the output amplifier to prevent overloading
of input sections in the following equipment such as mixing consoles
etc. When the button is pushed in, the output is attenuated by 20 dB.
All microphones come with an individual calibration chart of the self
noise, sensitivity and the individual frequency response.

results in 20 dB attenuation.
Important:
The microphone will only operate within it's specifications if
powered correctly.

Acoustic Pressure Equalisers
Available as optional acoustical attachments are also the APEs –
Acoustic Pressure Equalisers. The APEs use diffraction to passively
modify the sound field near the microphone diaphragm, thus changing
the microphone’s frequency response and polar response (see Fig. 14
and Fig. 15) without adding any electrical noise to the recording. The
size of the APE determines the acoustical changes of the micro-
phone. The APEs are precision made from a special compact nylon
material and will only fit the Types 4003 and 4006 fitted with the
standard Free-field Grid DD0251. There are three different APEs in
the range: L30B is a Ø 30 mm ball-shaped APE marked with a blue
dot, L40B is a Ø 40 mm ball-shaped APE marked with a green dot,
L50B is a Ø 50 mm ball-shaped APE marked with a red dot. The APEs
can be obtained separately or in the APE L6 Acoustic Modification kit.
See Fig. 17 for how to mount the APEs on the microphone.
The Passive Connection Converter
The PCC4000 Passive Connection Converter is an optional accessory
that makes it possible to run High-Voltage Microphones on standard
48 V phantom power with reduced microphone specs. The maximum
reduction of the microphone SPL handling capability will be 13 dB and
it is possible to drive up to 100 m 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 microphone. The output is a stan-
dard 3-pin male XLR-connector for connection to standard cables.

The Free-field Grid, Silver
The Free-field Grid DD0251 on the microphone cartridge is designed
to have a linear on-axis frequency response for free-field applications
(see Fig. 4 for frequency responses measured with the Free-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, Black
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 6 dB around 15 kHz (see Fig. 5) with-
out adding noise to the recording. This boost gives a linear diffuse-field
(far field) response up to 15 kHz.
The Close-miking Grid (Silver, Trapezoid)
The Close-miking Grid DD0254 is available as an optional accessory.
Due to its high frequency roll-off (beginning at 12 kHz and -3 dB at 20
kHz) it is designed to provide a soft and smooth high-end response,
especially suitable for close miking applications. The response is altered
acoustically without adding any noise or distortion. See Fig. 6 for
frequency response.
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 Free-field Grid DD0251.
When fitted, the Nose Cone gives the microphone a true omnidirec-
tional response even at high frequencies (see Fig. 11) and a linear dif-
fuse-field response (see Fig. 7). These qualities are useful at any dis-
tance for an even tonal balance of sound arriving at all angles of inci-
dence, 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 micro-
phone, which is the reason for normal flat fronted omnidirectional
microphones becoming more and more directional for higher frequen-
cies. There is, however, a slight high frequency boost on axis.

CARE OF MICROPHONE
It is important to bear in mind the following points with regard to
mounting, microphone care and the use of accessories:
The microphone cartridge is tightly secured to the main body housing,
and no attempt should be made to remove it. If a replacement car-
tridge is required, contact your local DPA Microphones representative.
Types 4003, 4006 and 4006-TL are supplied with an additional
Diffuse-field Grid DD0297 (see “Technical Description” and “Full
Specifications”). On delivery, the normal protection grid is screwed on
to the cartridge housing and normal finger torque is required to
remove it. Do not try to unscrew or tighten the protection grids with
any kind of tool 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.

USE OF ACOUSTIC PRESSURE EQUALISERS
Acoustic Pressure Equalisers 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.

Fig. 16. 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 influence on the
frequency response is negligible, the dust will not change the charac-
teristics of the microphone. Therefore cleaning the diaphragm is not
necessary and should not be attempted.
