Positioning the microphone
Boundary microphones make use of the pressure effects
at a room boundary and need to be mounted on a flat sur-
face:
Position Resulting sound Commentary
Altar or lectern:
on a sound-reflecting
surface
Less room resonance
portions or comb filter
elements;
improved speech
intelligibility and
greater gain reserves
in contrast to free-
standing microphones
Unobtrusive due to
flat design;
no microphones in
the field of vision
Conference rooms:
lying on the table;
directed towards the
conference
participants *)
Less room resonance
in contrast to free-
standing microphones
Microphones must
not be covered by
papers, folders or
similar objects

*) The cardioid pick-up pattern has an opening angle of
approx. 130°. Try to position the microphone so that the
sound source (conference participant, speaker or
instrument) is located in this angle area (see polar
diagram).
Theater stages:
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
Less room resonance
in contrast to free-
standing
microphones;
improved speech
intelligibility
Excellent rejection
of rumble noise; if
necessary, place
the microphone on
a soft pad (e.g.
mousepad).
If necessary,
combine with
overhead micro-
phones (e.g.
Sennheiser ME 36
with MZH 30 B &
MZC 30)
Grand piano / piano:
mounted to the
inside cover (=
sound-reflecting
surface) of the piano
or lying in the
instrument or on the
floor underneath the
piano
Very transparent and
powerful sound;
stereo sound image
can be shaped
individually,
depending on
microphone position
chosen
Instrument is easy
to mike, even
when the cover is
closed;
excellent
protection against
crosstalk into
other microphone
channels and
reduced volume on
stage
