The DPA 4055's frequency response curve shows a remarkably flat response, with a slight boost starting at 8kHz and extending out to about 12kHz. The key to this measurement is that the phase response specification looks like one of DPA's measurement microphones--remarkable for an instrument mic that costs $730 MSRP.

Maximum SPL is 164 dB SPL (peak) and the dynamic range is 132 dB. The transformer-less active output electronics requires +48-volt phantom power and will drive up to a 100-meter mic cable making it perfect for live stages and studios. The mic measures: 5.19-inches in length and has an asymmetrical design--offset from center line, so the 2.2-inch-wide, removable windscreen (for cleaning) can be placed exactly out in front, inside, against the beater head, or anywhere you want around a kick drum.

To enable this freedom of placement, the DPA 4055 is internally shock-mounted and comes with a locking mic clip called the UA0961. This all-metal clip grips the mic solidly and, along with the windscreen, allows confidence for whatever placement gets the sound you're looking for. And that is the whole idea here: easily provide a flat, non-distorted capture of high SPL sound that's ready to be "carved" into shape later, if needed.

I found that the DPA 4055 does the job in the most elegant and non-intrusive way in the recording studio. Highly recommended!
