Use the supplied adhesive compound. Although it will
leave no residues when removed from most surfaces,
there may be a minimal risk of old or delicate lacquer
coats being damaged.
3.5 Directivity
The microphone's omnidirectional (hemispherical) po-
lar pattern may cause unwanted sounds to be picked
up from unexpected directions.
To suppress these unwanted sounds, you may, for
instance,
mount the microphone in the center of a plexiglass
panel about 3 feet square and align the plexiglass
panel with the desired sound source (see fig. 6), or
place thick carpet between the microphone and
the unwanted sound source(s) as shown in fig. 7 to
reduce the spillover.

3.6 Bass Cut Filter

Low-frequency rumble or wind noise from sound
sources we do not normally perceive as irritating, such
as air conditioning, traffic, or structure-borne noise,
may become clearly audible and therefore definitely
irritating on a recording. The 150 Hz bass cut filter in-
tegrated in the phantom power adapter allows you to
reject this unwanted noise without changing the sound
of the instrument or voice you are recording. The filter
slope is 12 dB/octave (approx. 1:4).

pet to reduce spillover.
