DPA Type 4011 Cardioid Microphones

Product Information

The product is a cardioid microphone available in two types:

Type 4011 and Type 4012. It is a pre-polarized condenser microphone that operates on a pressure gradient principle. The microphone requires a power supply, with Type 4011 being powered by Phantom P48 and Type 4012 requiring the HM A4000 Two-channel High-Voltage Microphone Amplifier – 130V or PCC4000 Passive Connection Converter for P48. The microphone has a cardioid directional characteristic and comes with an individual calibration chart for self-noise, sensitivity, and frequency response.

Product Usage Instructions

Ensure that the microphone is powered correctly according to its specifications.
To connect the microphone, use the appropriate output socket based on the microphone type: Fig. 1 for Type 4012 and Fig. 2 for Type 4011.
For Type 4011, use the switch on the XLR connector to select between 0dB and 20dB attenuation. Pressing the switch results in maximum attenuation.
For close-miking high SPL sound sources using Type 4011, utilize the 0dB/20dB attenuation feature to prevent overloading the console input amplifier.
Both Type 4011 and Type 4012 utilize state-of-the-art low-noise preamplifier technology and are driven with unity gain.
Refer to the individual calibration chart provided with the microphone for accurate information on self-noise, sensitivity, and frequency response.

Technical Description

The cartridge
Directional microphones Type 4011 and 4012 use a 19mm diameter pre-polarized 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 backport 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 a 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 microphone 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 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 phantompower 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.

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

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 cartridge is required, contact your local DPA Microphones representative.
Use of a 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.
