STEREO APPLICATIONS
he KM 100 system accessories make it possible to realize compact
setups for all common stereo configurations. The accessories described
below can simply be mounted to any stand, preferably with a shock-
absorbing rubber pad. If necessary, the Z 26 mt shock mount can also
be inserted to reduce body sound transmission even further.
MS Configuration
The STH 120 stereo mount makes it possible to position two active
capsules in an “over/under” configuration and orient them in relation to
the sound source using the ball joint on the mount.
AK 20 + AK ... + 2x LC 3 KA + STH 120
If the active capsules or microphones are to be mounted in elastic
mounts, this can be done using the DA-AK and DA-KM elastic sus-
pensions. See the section “Microphone Fishpoles”.
The MTX 191 A matrix amplifier is designed to power and matrix the
two active capsules specifically in applications like this one. See the
section “Introduction/Power and Matrixing”.
XY Configuration
The easiest way to position two capsules coincidentally is by using the
‘XY clamps’ of the STH 100 stereo mount. This permits variation of
the included angle between the two capsules within a range of 30° to
180°, while keeping the centers of the membranes always positioned
ideally over and under one another. When mounted on a table stand,
this is the smallest possible solution at all.

For complete microphones, or even active capsules, an
XY configuration is realized using the DS 110 or
DS 120 double mount. The microphones in the
SG 21/17 mt stand mount are snapped onto
the double mount. The double mount, which
is likewise adjustable over a large range of an-
gles, is mounted on a table stand or stand.
The capsules are positioned next to one an-
other.

AB Configuration
The DS 120 double mount can also be used for
(small) time based AB stereo setups. The microphones
or even just the active capsules are mounted with the
swivel mounts on the double mount with a definite
spacing and any angle of the user’s choosing.

ORTF Configuration
The “ORTF clamp” of the STH 100 stereo mount
holds two active capsules in the standard ORTF con-
figuration with an included angle of 110° and a distance
of 17.5 cm between membranes.
2x AK ... + 2x LC 3 KA + STH 100
The DS 120 double mount can be used for complete
microphones or active capsules.

Blumlein Configuration
The so-called Blumlein configuration is a special type
of XY technique with two microphones with a figure-
eight characteristic positioned above one another and
an included angle of 90°. This is easy to realize with a
DS 120 double mount attached to a horizontal boom.
The two microphones or active capsules are screwed
onto the DS 120 in their swivel mounts.
