Miniature Microphone Application Guide

Small, Elastic Setups
Apart from the acoustical quality of signal reproduction, the biggest prob-
lem in tabletop applications can be suppression of body noise. This
should have been taken into account already in the planning phase by
using a solid table construction with high internal damping. If this is not
the case, then elastic suspensions or other damping components are in-
dispensable.
The Simplest Variants
If only light body noise occurs, then it is sufficient to insert a Z26mt
shock mount between the microphone mount and the table stand.
KM ... + SG 21/17 mt + Z 26 mt + MF 3
If the microphone is mounted on the table stand in an EA 2124 A elas-
tic suspension, even loud, low-frequency noise is suppressed effectively.
The double gooseneck joint at the base of the suspension makes it pos-
sible to point the microphone in any direction.
KM ... + EA 2124 A + MF 3
The Invisible Variant
For work with cameras, the EA 2124 A elastic suspension should not
be visible. The elastic suspension can be mounted, for example, on a
table flange, so that the microphone peeks out through a hole in the
table. To permit free vertical alignment of the capsule, the SG-AK swivel
joint is inserted between the active capsule and the output stage. Thus
it is easy to aim the capsule at the speaker.

Large Setups
Positioning the microphone closer to the speaker improves the signal-
to-noise ratio as well as cancelling table reflections. For non-camera work,
e.g., in radio, the following variants are recommendable:
The Simplest Variant
The SMK 8 i gooseneck permits simple mounting of an entire micro-
phone on a tabletop stand, for example, the MF 3. The gooseneck in-
corporates an XLR 3 connector; the cable runs through the inside and
exits on the side above the tabletop stand.
KM ... + SMK 8 i + MF 3
The Elegant Variant
A more discrete solution is made possible by capsule
extensions, here, for example, the KVF 118 KA flexi-
ble capsule extension. It is mounted to the tabletop
stand using the SG 100 stand mount and makes it pos-
sible to position the capsule very close to the speaker.
AK ... + KVF 118 KA + SG 100 + MF 3
The Invisible Variant
In order to keep the tabletop stand out of the picture,
the capsule extension can also be fastened underneath
the table. For this, the KVFF 148 KA capsule exten-
sion permits free alignment of the capsule. The cap-
sule extension is mounted to a TF 221 c table flange
under the table using the SG 100 stand mount. In ad-
dition, the table flange incorporates a rubber metal con-
nection for noise suppression.

SG 100 + TF 221 C
The Upside Down Variant
In some studios, it is possible to suspend microphones
from above. This makes it possible to keep the tabletop
entirely free and decouple the microphone from the body
noise of the table. Depending on the geometry of this
configuration, the microphone can be prevented from
picking up reflections from the tabletop by selecting a
capsule with the appropriate directional characteristic.
The STV stand extensions are fastened to the ceiling
with the help of a table flange. The long KVF 158 KA
capsule extension is held by the SG 100 stand mount,
making it possible to position the capsule so that is very
close to the speaker. If necessary, a rotatable interme-

diate piece can be inserted between the swivel mount
and the stand extension.

There is also a DS 100 double mount available for the
capsule extensions. Since this solution presents itself
above all for stand-based solutions, however, the
DS 100 is presented in the next section.
