Operation
Operation
Positioning the microphone in a drum
Place the e 901 in the drum. Position the microphone so that its sound inlet basket is directed
upwards.
It is vital to observe the following notes:
Position Resulting sound Commentary
A Much resonance
Much attack
Less attack: Turn the micro-
phone away from where the
beater strikes.
Position the microphone at the bottom of the kick
drum, approx. 10–20 cm from the batter head.
B The e 901 is used for picking
up the attack, the e 902 for
picking up the fundamental.
Combined with an e 902 positioned at the resonant
head. The lower micro-phone must be phase-rever-
sed to avoid phase-cancellation effects due to the
second microphone being on the other side of the
drumskin.
A B
Positioning the microphone on sound-reflecting surfaces
Place the e 901 on the desired sound-reflecting surface. Position the microphone so that its sound
inlet basket is directed towards the sound source.
It is vital to observe the following notes:
Position Resulting sound Commentary
C Less room resonance por-
tions or comb filter elements
Improved speech intelligi-
bility
Greater gain reserves in
contrast to free-standing
microphones
Lying on the altar or lectern. Unobtrusive due to flat
design. No microphones in the field of vision.
D Less room resonance in
contrast to free-standing
microphones
Lying on the conference table, directed towards the
conference participants. Microphone must not be
covered by papers, folders or similar objects.
E Less room resonance in
contrast to free-standing
microphones
Improved speech intelligi-
bility
Lying at the edge of the stage and directed towards
the stage. As spot microphone of the PA system or
for monitoring purposes in the theater cloakrooms.
Excellent rejection of rumble noise; if necessary, pla-
ce the microphone on a soft pad (e.g. mousepad).
If necessary, combine with overhead microphones
(e.g. Sennheiser ME 36 with MZH 30B & MZC 30).
