MPR 211 – Condenser Microphone

4. Operating Mode

ON/OFF

The microphone is turned on or off via a button. The LED will illuminate

red when the microphone is turned on.

PTM (Push-To-Mute)

The button operates as a cough button. The microphone is always

turned on. The LED will illuminate red. When you hold down the

button, the microphone is off and the LED will extinguish.

PTT (Push-To-Talk)

The microphone is on, as long as you hold down the button. The LED

will illuminate red. When you release the button, the microphone is

off. The LED will extinguish.

Output Level

The output level can be set to:

High, Mid, Low.

5. Connection

The MPR 211 provides a bare ended cable. The functions depend on

the selected operating mode Autonomous, Remote or External Logic.

For powering a phantom power between 24 or 48 V is required,

irrespective of the selected operating mode.

For more information, please refer to the wiring diagram.

Thank you for selecting the MPR 211 condenser microphone from

beyerdynamic. Please take some time to read carefully through this

product information before using the product.

1. Safety Information

• Protect the microphone from moisture and sudden impacts to

prevent damage. You could either injure yourself or others.

• Do not blow into the microphone, you could damage the transformer.

It is preferable to carry out a speech trial.

• When using wired microphones always ensure that the microphone

cable is laid so that it does not present a trip hazard.

2. Application

The MPR 211 is a modern desktop microphone, which is ideal for

discussions, tele/video conferencing and announcements.

The Revoluto technology with 17 integrated microphone capsules

provides a so-called corridor characteristic, which ensures a wide range

of good voice quality. Within this range the speaker can move freely,

i.e. he/she can stand up or sit down, move his/her head and move

towards or away from the microphone.

On the left hand side the MPR 211 provides an LED, which will

illuminate when the microphone is switched on.

3. Basic Function

Autonomous

With this function you can operate the microphone via the built-in or

external button.

Remote

With this function you can only operate the microphone via an

external button. The button on the front of the housing is deactivated.

External Logic

The function is used when operating the microphone with external,

logic controls. The microphone is always active. With this function the

internal logic with micro controller control is deactivated. A typical

application is for example the “Voice Activation” mode in conjunction

with a digital audio matrix.

At the bottom you can select between three

basic functions.

An arrow points to the selected basic

function.

At the bottom you can select between three

operating modes. The different operating

modes are controlled and monitored by a

micro controller. An arrow points to the

selected operating mode. This function is only

available with the basic functions Autonomous

and Remote.

The connecting cable can be guided to the rear or to the bottom.

For this you can remove the two small screws, turn the cable duct

appropriately and tighten the screws. The standard cable exit is on the

rear.

6. Microphone Positioning

Each speaker should have his or her

own microphone.

The MPR 211 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.

Two MPR 211 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 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 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.
