6. Microphone Positioning

Each speaker should have his or her
own microphone.
The MPR 211 B must not directly be
placed with its back in front of a wall.
The minimum distance to the wall
should be 15 to 20 cm. An acoustic
shadow due to obstructions, such as
books, newspapers or conference
papers, compromises performance
greatly.
When notebooks are being used, it is
also necessary to consider the micro-
phones. Notebooks should always be
positioned to the side of the micro-
phones. Otherwise, when opened, the
LCD screen would obstruct the
sound. This also applies to free-
standing monitors. Sufficient
distance is the key to the directional
effect and good feedback suppression.
Moreover, notebooks often have fans
at the back. The noise of the fan
would then be fully picked up by the
microphone.

MPR 211 B – Condenser Microphone
Two MPR 211 B should not be directly
placed back to back, because the
acoustical corridor effect does not
work in this case. As shown in the
previous example the minimum
distance should be 15 to 20 cm.
For more information about application examples, please refer to the
beyerdynamic "Revoluto Design Guide".

7. Installation

For permanent installation on a table, the MPR 211 B provides screw
sockets on the left and right hand side at the bottom of the housing.
Warning:
We recommend that the threaded sleeve is screwed into the micro-
phone approx. 1/5" (5 mm). Refer also to the drilling template.

8. Maintenance

Use a soft, damp cloth for cleaning the MPR 211 B microphone. If
necessary, you can use a gentle cleansing agent (such as washing-
up liquid). Make sure not to allow any water to enter the transducer
element and never use any solvent cleansers.

9. Service

Servicing must be carried out by qualified service personnel only.
Dismantling the microphone yourself will invalidate the guarantee.
