The BLM6000 is an accessory that will extend the use of

your

4061, 4062, and 4063.

By placing a microphone close to a reflective 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 microphone

correctly! If not the sound may suffer from coloura-

tion.

The smoothest frequency response is achieved with the dia-

phragm perpendicular to the reflecting boundary. In order

to identify the position of the membrane you may 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.
