The Heil HDK drum kit series is a culmination of over 2 years spent on the road with leading drummers. They gave us their ideas, their dreams and their needs which we turned into reality. Every component of a drum kit needs special attention when it comes to reproducing the sound accurately. There are many drum microphones out there but the artists that helped design the Heil drum microphones wanted more accuracy, not just level. Each one of them were tired of little plastic toys that did not reproduce well. They all agreed, after hearing and using the new technologies of the Heil drum microphones, that they had never heard this level of quality reproduction.
The PR 48 kick drum microphone starts with our 1.5" large diaphragm dynamic element sealed in a vulcanized shock mount and fed with a specially designed low pass filter that creates a +10 dB rise from 50 to 100 Hz. - right where the kick drum resonates. We built a + 4dB rise from 3.5 to 5 K to pick up the beater and drop off drastically after 8.5 K to eliminate any unwanted internal sounds. The total frequency response is 30Hz - 8.5kHz. Its rear rejection is -40dB @ 180° off axis. It can handle +148dB SPL.
The PR 48 metal housing was designed with a slanted entrance for the XLR at the suggestion of several drum techs so the cable assembly is easier to connect. The microphone provides a 600 ohm balanced output and is finished in flat black emron with red grills.
