A very common technique when recording drums is to close-mike – put microphones very close to at least the kick, snare, hi-hat and toms – and also have a room mic or a pair of room mics to capture the sound of the overall drum kit. The room mics are usually several feet away from the drum kit. Then you mix the room mics in along with all the drum mics.
Another common thing to do is put a lot of compression on the room mic, which makes the entire drum mix sound, for lack of a better term, huge. But sometimes using a ton of compression, such as using a ratio of 20:1, on a drum room mic can over-accentuate the sound of the cymbals. Having your drum mix sound like it’s swimming in cymbals pretty much ruins the sound you were going for with the room mic. But you can fix that by using an equalizer (EQ) effect to basically filter out the main frequencies where the cymbals live.
Graham Cochrane shows you how to do that in this very informative video:
