have to temporarily remove the microphone
grid (see picture). When you mount the
microphone in the BLM, be sure that the
mesh is completely hidden, so there are no
openings, as they will affect the sound.
Please note: The microphones must be
mounted with the short grid (soft boost
grid). The long grid will not fit into the disc.
Using the Boundary Layer Mount
When mounted in the BLM6000 you can
put the microphone on all surfaces that
reflect sound i.e. tables, lecterns, etc. Even
floors, walls and ceilings are very effective
as boundaries when the BLM6000 is
attached to it.
In general
The pressure zone principle will be more
prominent in a larger frequency range, the
larger the surface the BLM6000 is placed
on. Conversely, you can experiment with a
placement close to the edges of a table, to
the edge of the stage floor or lectern in order
to obtain bass roll off.
If you want to place the disc on a ceiling or
a wall, simply use double-sided tape.
Please find some graphs that illustrate the
frequency response of the microphone
mounted in the BLM.
The BLM6000 is an accessory that will
extend the use of your DPA miniature
microphones i.e. DPA 4060, 4061, 4062,
and 4063.
By placing a microphone close to a reflec-
tive boundary, you will benefit from the
special characteristics of the sound field
found here: a 6 dB gain of direct sound and
only 3 dB gain of the diffuse sound. This
means that the sound picked up has both
greater clarity and intelligibility compared to
the sound picked up in "free air".
Mounting the microphone
It is very important to mount the micro-
phone correctly! If not the sound may suffer
from colouration.
The smoothest frequency response is
achieved with the diaphragm perpendicular
to the reflecting boundary. In order to iden-
tify the position of the membrane you may
