Positioning the microphone
Kick drums
Position Resulting sound Much resonance, much attack Less attack: Turn the microphone away from where the beater strikes. The 901 is used for picking up the attack, the 902 for picking up the fundamental. Commentary Position the microphone at the bottom of the kick drum, approx. 10�20 cm from the batter head. Combined with an 902 positioned at the resonant head. The lower microphone must be phase-reversed to avoid phasecancellation effects due to the second microphone being on the other side of the drumskin.
In order to prevent interference due to crosstalk between adjacent sound sources, try to position the microphone so that the interfering sound source is located in the angle area of the highest cancellation of the microphone (approx. 180°; see polar diagram).
