The Heil PR 48 kick drum mic starts with Heil's 1.5" large diaphragm dynamic element sealed in a vulcanized shock mount and fed with a specially designed low-pass filter that creates a 10dB rise from 60Hz to 100Hz — right where the kick drum resonates. The drum microphone stays out to 7.5 kHz and drops off drastically to eliminate any unwanted internal sounds. The total frequency response is 30Hz - 8.5kHz (4dB rise @ 4500Hz). Its rear rejection is -40dB @ 180° off-axis. It can handle +148dB SPL. The Heil PR 48 microphone's metal housing was designed with a slanted entrance to the 3-pin XLR so the cable assembly is easier to connect. The microphone provides a 600 ohm balanced output.The Heil HDK drum kit series is a culmination of over 2 years spent on the road with leading drummers. They gave Heil their ideas, dreams, and needs which Heil then 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 technologies of the Heil drum microphones, that they had never heard this level of quality reproduction..
