908

908 B / 908 D / 908 B ew / 908 T ew

These microphones are professional pre-polarised
condenser microphones. An extended dynamic range and
a well balanced frequency response deliver an out­standing signal quality with excellent projection and the
lowest possible distortion. An excellent directivity across
the whole frequency range enables the mics to handle the
highest signal levels without feedback.

The microphone 908 D has been developed especially
for drums and percussion. The 908 B is designed for
wired recording of wind instruments, but because of its
instrument clamp it is also paricularly suitable for drums
with suspension systems or congas. There are two special
types of microphones for use with ew bodypack
transmitters: 908 B ew for saxophone, 908 T ew für
trumpets, flugelhorns and trombones.

Due to their phantom powering capability, the mics are
especially suitable for use with professional mixing
consoles. Alternatively, they can be used with any
evolution bodypack transmitter for wireless applications.

Extensive damping and shock mounting isolates the
capsules from extraneous vibrations, impact and handling
noise

.

The long, flexible goosenecks enable the mics to be
optimally positioned on the instrument.

Positioning the microphone

Wind instruments ( 908 B / 908 B ew / 908 T ew)

Position Resulting sound Commentary

Reduced ambient
noise

Use the MZH 908 B
clamp to attach the
microphone to the
bell of the
instrument.

Clear, powerful
sound

Balanced, natural
sound

To reduce ambient
noise (at the
expense of the true
“Saxophone
sound”) direct the
microphone into the
bell (as illustrated).

For a Saxophone,
the microphone
should normally be
directed partly
towards the bell and
partly towards the
body of the
instument.

Drums / Percussions ( 908 D)

Position Resulting sound Commentary

More fundamental,
little overtones

Less fundamental,
many overtones

Pronounced
proximity effect

Position on the
drum:
3–5 cm above the
drumskin, directed
towards the center
of the drumskin, the
fundamental to
overtones ratio can
be adjusted by
changing the angle
of the microphone.
The most balanced
results are obtained
at an angle of
30–60°.

Optional:
tangential position
of the gooseneck in
order to reduce the
distance to 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).

To attach the MZH 908 D drum clamp, snap
it onto the rim of the drum as follows:

Put the upper part of the clip (1) onto the
rim and clip on by pushing down in a rota­ting action (2) until it clips into place.

Commentary

To attach the microphone to the drum
clamp:
Loosen the knurled screw. Insert the
gooseneck of the microphone from the side
into one of the two slots and tighten the
knurled screw.

You can attach two microphones to the
drum clamp (e.g. for picking up two toms in
cramped space conditions). To do so, use
both slots of the drum clamp.

Optimum positioning of the microphone

The various adjustment possibilities of the MZH 908 D
and MZH 908 B clamps together with the flexible goose­neck enable the microphone to be optimally positioned
on the sound source (see arrows in the diagrams below).
