> The overheads were Neumann 87 or 47, and on the hi?hat I used a Neumann KM84, which gives a nice crisp sound, but also has enough body in it. There is some tone to the hi?hat and you don't want to get rid of it and have just this ticky?ticky sound. According to Mike Fraser, mix engineer, Rudd used this mic for the overhead.more
"I don't ever use dynamic mics on a drum kit if I can help it: it'll either be ribbons or condensers. The exception would be an [Electro?voice] RE20 inside the kick, but I tend to try to use a [Neumann] U87 or 47 outside, and a Yamaha NS10 driver on the bottom. I try to line them up equidistant, so that theoretically it would always phase?align. I'll use [Neumann] KM84s on snare, top and bottom."more
The KM 84 is a small-diaphragm FET condenser with a fixed Cardioid pickup pattern. It was the world’s first phantom-powered microphone, built to run on 48v DC. Its design goal was to be as small as possible; the model name ‘KM’ stands for Kleine Mikrofon (“small microphone”). The model number indicates the powering mechanism (8 = phantom power) and polar pattern (4 = cardioid). Although discontinued in 1992, the KM-84 remains a favorite of vintage mic enthusiasts for drum overheads and hi-hat applications. Neumann’s KM 184 was intended to be a replacement for the KM 84, but the two mics sound sufficiently different that the KM 84 has remained a standard by which modern FET pencil mics are judged. (See the KM 184 page for additional discussion of the physical and sonic differences between these microphones.) The mic is known for having an exceptionally flat frequency response and its ability to maintain its cardioid pickup pattern across the frequency spectrum.
