Table Mounting of Modular Microphones
A good speaker's desk, or a table on which microphones are to be set up, calls either for a rather heavyweight construction or for a perforated metal surface to be used. A heavy tabletop will not flex much; a perforated surface on the other hand will radiate and reflect less sound energy than one which is flat and solid.
 It is not always necessary to use several directional microphones (e.g. cardioids) when recording roundtable discussions. A single boundary-layer microphone such as the BLM 03 Cg, concealed perhaps beneath a thin covering cloth, can be placed at the center of the table, solving the problem in elegant fashion. This type of microphone is also significantly less sensitive to solid-borne noise than an ordinary directional type such as a cardioid. Even if monitor loudspeakers are nearby, the risk of feedback is less than might be expected since the boundary-layer effect discriminates in favor of direct sound. In addition, by using one boundary-layer microphone instead of several conventional microphones, the risk of phase cancellation is greatly reduced.
 The photo at right shows a 350 mm tube and a 100 mm STR support rod. If greater extension is required for either part of the setup, two AF 1 adapters should be mounted one above the other with the threaded adapter ST 20 M. That approach would also be recommended if the support rod must be tilted at a 45° angle or greater.
To run the Colette cable through the AF 1, its output connector (which is larger than 20 mm) must be disassembled, unsoldered and removed, then resoldered on the other side.

 Miniature Goosenecks
SKC 200g, SKC 300g, SKC 420g
These goosenecks are used directly between capsules and amplifiers of the CMC series. For mounting in a table top, the AF 1 flange (not included) offers good isolation from solid-borne noise. Mounting is generally quite straightforward and simple.
 A CUT variable low-cut filter can be used on the amplifier – though the filter does not fit into the AF 1, so it would have to “ride“ above the table top.
Lengths:
SKC 200g: 200 mm
SKC 300g: 300 mm
SKC 420g: 420 mm, 120 mm of which is rigid
Other lengths on request.

 When there is a particularly great need to isolate the microphone from solid-borne noise, the elastic suspension A 20 S can be used along with the SKC 200g. In an arrangement as shown at right, only the gooseneck and capsule will be visible, and the suspension will be relatively soft.
Further ways of mounting microphones on a table with elastic suspension
Variant 1
Simple mounting and a relatively restrictive grip.
MK... microphone capsule + KC cable
SGC miniature swivel stand coupler
STR-TC vertical support rod
ST 20-3/8 threaded adapter
AF 1 flanged mounting adapter
Variant 2
Very good isolation from solid-borne noise, and elegant appearance due to the smaller opening required in the table top.
MK... microphone capsule + KC cable
SGC miniature swivel stand coupler
STR-TC vertical support rod
ST 20-3/8 threaded adapter
A 20 S elastic suspension
F 5g table mounting flange
Variant 3
 Like variant 2, but because of the weight increase caused by the GVC, the stiffer version of the A 20 elastic suspension should be used.
MK... microphone capsule
GVC capsule swivel
CMC 6 Ug microphone amplifier
A 20 S elastic suspension
F 5g table mounting flange
Variant 4
Simple mounting and more restrictive grip than with variant 3.
MK... microphone capsule
GVC capsule swivel
CMC 6 Ug microphone amplifier
AF 1 flanged mounting adapter
Table Mounting of CCM Compact Microphones
The photo at right shows a 350 mm tube and a 100 mm STR support rod. If greater extension is required for either part of the setup, two AF 1 adapters should be mounted one above the other with the threaded adapter ST 20 M. That approach would also be recommended if the support rod must be tilted at a 45° angle or greater.
