TECHNICAL DESCRIPTION
The cartridge
Omnidirectional (pressure) microphones DPA 4004 and 4007 use a
12 mm (0.47 in) diameter prepolarised 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 self noise
of the cartridge is typical 24 dB(A) re 20 μPa and the nominal sensi-
tivity of 4004 and 4007 are 10 mV/Pa and 2.5 mV/Pa respectively.
Due to the size of the cartridge it can handle extremely high SPLs,
has an extended linear frequency response up to 40 kHz and a high
degree of omnidirectionality, even for higher frequencies. For opti-
mum stability the microphone cartridge has undergone a special
pre-aging process which releases all tensions in the materials and
stabilizes the polarisation voltage.
The preamplifiers
Types 4004 and 4007 are acoustically identical, but differ in their
preamplifier powering system. The 4004 is powered with 130 V via
the HMA5000 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 10 dB higher SPL than similar microphone types po-
wered through conventional P48 systems (4004: 168 dB SPL peak
and 4007: 155 dB SPL peak).
Furthermore, the 4004 together with the HMA5000 is a totally
tranformerless system and therefore has an extended low-frequen-
cy handling capability (10 Hz to 40 kHz ± 2 dB). The 4007 is po-
wered via a standard P48 system and is equipped with a high quali-
ty audio transformer and a standard 3-pin XLR-connector (see Fig.
2 for pin designation). Types 4004 and 4007 use state of the art
low-noise preamplifier technology and are driven with unity gain.
All microphones come with an individual calibration chart with the
specifications of self noise, sensitivity and the frequency response.

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

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 48 V phantom power with reduced microphone specifications.
The maximum reduction of the microphone SPL handling capability
will be 13 dB and it is possible to drive up to 100 m (328.1 ft) 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 standard 3-pin male XLR-connector
for connection to standard cables.

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 hou-
sing, and no attempt should be made to remove it. If a replacement
cartridge is required, contact your local DPA Microphones represen-
tative.
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.
