The DPA 4004 High Spl, High Voltage Omnidirectional Microphone. Total acoustical transparency and ultra-high SPL handling capability.

The DPA 4004 High-SPL Omnidirectional Microphone is an omnidirectional hi-voltage (130 V) close-miking specialist with an extended on-axis frequency response from 10 Hz to 40 kHz (±2 dB). The 4004 is a Reference condenser microphone specially designed to handle extremely high sound pressure levels - up to 168 dB 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 due to the special hi-voltage powering system. The 4004 is acoustically identical with the reference microphone Type 4007, but differs in the powering system and the fact that the 4004 has a transformerless output. The DPA 4004 is totally transparent and is the perfect choice in all close-miking recording situations regardless of the sound source. It is often the first choice for picking up drums, percussion and brass instruments, whenever the natural and non-distorted result is paramount. Type 4004 is, due to its linear qualities, also used as a reference microphone in both microphone comparisons and acoustic test equipment. The DPA 4004 is an industry favourite in recording and sound reinforcement applications whenever the natural, non-distorted result is paramount.
