Table Mounting
Microphone Setups with
RC Active Extension Tube or
RL Straight Extension Tube
The photos at right show 350 mm tubes and 100 mm
STR support rods. If greater extension is required for
either part of the setup, two AF 1 table mount elastic
suspensions should be mounted one above the other
with the mounting cylinder ST 20-3/8. The latter has a
cylindrical base which fits inside the AF 1 suspensions,
plus a threaded upper part to hold the STR support rod
(which should be the 61 mm version – please specify
this length when ordering). This arrangement is also
recommended for situations in which the Active
Extension Tube must be tilted at a 45° angle or greater.
To run the Colette cable through the AF 1, its out-
put connector (which is larger than 20 mm) must be
disassembled, unsoldered and removed, then resol-
dered on the other side. The cable passes through a
notch in the cylinder.

Setting up microphones on a table top
A good speaker's desk, or a table on which micro-
phones are to be set up, calls either for a rather heavy-
weight construction or for a perforated metal surface
to be used. A heavy tabletop will not flex much; a per-
forated 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 round-
table discussions. A single boundary-layer microphone
such as the BLM 03 Cg can be placed at the center of
the table or the BL CCM 3 can be built into the table
top and concealed perhaps beneath a thin covering
cloth, 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 micro-
phone instead of several conventional microphones,
the risk of phase cancellation is greatly reduced.
