DPA Types 4007 and 4004 are acoustically identical, but differ in their preamplifier powering system (the 4004 is designed to handle approximately 13 dB higher SPL).

The exceptional accuracy and transparency of the DPA 4007 makes it an industry standard for acoustic measurement: It's used as a reference microphone for both microphone comparisons and acoustic test equipment. DPA's 4007 is also an industry favorite small diaphragm condenser for recording drums, percussion and brass instruments, whenever a natural, high fidelity result is paramount.

A close miking specialist, the DPA 4004 specially designed to handle extremely high sound pressure levels - up to 168dB SPL before clipping occurs. It has an unbeatable dynamic range of 124 dB from the noise floor to 1% THD, and an extended headroom of 20 dB up to clipping level.

While acoustically identical to the reference microphone Type 4007, the DPA 4004 differs in the powering system and the fact that it has a transformerless output. Thanks to the special hi-voltage (130 V) powering system, the 4004 can handle approximately 10 dB higher SPL than similar microphone types powered through conventional P48 systems.

An ideal measurement mic, the exceptional accuracy and transparency of the DPA 4004 makes it an industry standard for acoustic measurement. It's also an industry favorite for close miking recording situations where a natural, high-fidelity result is paramount.
