It is vital to observe the following notes:
Position Resulting sound Commentary
A More fundamental
Little overtones Position on the drum: 3 to 5 cm above the drumskin
The fundamental to overtones ratio can be adjus-
ted by changing the angle of the microphone. The
most balanced results are obtained at an angle of
30 to 60°.
B Less fundamental
Many overtones
C Use of a second e 904 for picking up the bottom of
the drumskin and the snares.
NB: The lower microphone must be phase-rever-
sed to avoid phase-cancellation effects due to the
second microphone being on the other side of the
drumskin.
