The cartridge
Types 4004 and 4007 are omnidirectional (pressure) microphones which
use a 12mm 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 self noise of the cartridge is typical 24dB(A) re. 20µPa
and the nominal sensitivity of the Types 4004 and 4007 are 10mV/Pa and
2.5mV/Pa respectively. Due to the size of the cartridge it can handle
extremely high SPLs, has an extended linear frequency response up to
40kHz and a high degree of omnidirectionality, even for higher frequencies.
For optimum stability the microphone cartridges have undergone a special
pre-aging process which releases all tensions in the materials and stabilizes
the polarization voltage.
The preamplifier
Types 4004 and 4007 are acoustically identical, but differ in their
preamplifier powering system. The 4004 is powered with 130V via the
HMA4000 Two-Channel High-Voltage Microphone Amplifier and has a
modified 3-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 powered
through conventional P48 systems (4004: 168dB SPL peak and 4007: 155dB
SPL peak). Furthermore, the 4004 together with the HMA4000 is a totally
tranformerless system and therefore has an extended low-frequency
handling capability (10Hz to 40kHz ± 2dB). The 4007 is powered via a
standard P48 system and is equipped with a high quality 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 microphones will only live up to their specifications if
powered correctly.
The Passive Connection Converter
The PCC4000 Passive Connection Converter is an optional accessory that
makes it possible to run High-Voltage Microphones on standard 48V
phantom power with reduced microphone specifications. 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 microphone. The output is a standard 3-pin male
XLR-connector for connection to standard cables.

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 housing,
and no attempt should be made to remove it. If a replacement cartridge
is required, contact your local DPA Microphones representative.
•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.
