The cartridge

Directional microphones Type 4011 and 4012 uses a 19mm diameter
prepolarized pressure gradient condenser-microphone cartridge with a first
order cardioid pick-up pattern. The diaphragm is of PVDF with a vaporized
layer of aluminum. This material is non-hygroscopic, i.e. it does not absorb
water, and is highly resistant to the most aggressive kinds of humidity. 
The microphone housing is German silver. The large spacing between the
diaphragm and the back plate in this cartridge makes the microphone highly
insensitive to temperature influence. The microphone cartridge is designed to
have a linear on-axis response from 40Hz to 20kHz ±2dB measured in 30cm
distance (see Fig. 4). Great attention has also been paid to the microphone’s
off-axis performance during the design process (see Fig. 4). The diaphragm is
protected from dust by an acoustical transparent net behind the front
protection grid and inside the back port of the cartridge. 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 4011 and 4012 are acoustically identical, but differ in their preamplifier
powering system. The 4012 is powered with 130V via the HMA4000 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 10dB higher sound pressure level than
similar microphone types powered through conventional P48 systems (4012:
168dB SPL peak and 4011: 155dB SPL peak). Both the 4011 and the 4012
together with the HMA4000 are transformerless. The 4011 is powered via a
standard P48 system and is equipped with standard 3-pin XLR-connector
(see Fig. 2 for pin designation), but has an attenuator switch built into the

connector (see Fig. 3). The 0dB/20dB attenuation allows the 4011 to be used
for close-miking high SPL sound sources without the output of the micro-
phone overloading the console input amplifier. Types 4012 and 4011 use state
of the art low-noise preamplifier technology and are driven with unity gain.

All microphones come with an individual calibration chart of the self noise,
sensitivity and the individual frequency response.

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 micro-
phone. The output is a standard 3-pin male XLR-connector for connection to
standard cables.

Important: The microphones will only live up to their specifications if
powered correctly.

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.
