904
High-quality dynamic microphone with cardioid pick-up
pattern.
Due to its compact design, the microphone is ideal for use
with drums (toms and snares). It can easily be positioned
in cramped space conditions (e.g. below the cymbals) and
the supplied MZH
precisely attach it to the rim of the instrument.
The 904 is also suitable for miking guitar amplifiers,
percussions as well as brass and woodwind instruments.
A rugged full metal body effectively protects the
microphone from impact damage.
The XLR connector turned by 45° allows the space saving
positioning of the microphone in the case of angled
connectors.
604 microphone clamp allows to

Less fundamental
tone,
many overtones
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°).
Position on the drum:
3–5 cm above the
batter head, the
fundamental tone to
overtones ratio can be
adjusted via the angle.
The most balanced
results are obtained at
an angle of 30–60°.
Use of a second 904
for picking up the
resonant head and
the snares. If necessary,
activate phase reversing
for one of the
microphones.
