Connecting And Positioning Of Remote Antennae - Beyerdynamic MCW-D 200 Bedienungsanleitung

MCW-D 200 – Control Unit
3.3

Connecting and Positioning of remote Antennae*

The MCW-D 200 control unit can also be operated with remote antennae. Low attenuation connecting cables are available in different lengths.
Please note that all three antennae have to be connected remotely. The transmitting antenna should be mounted in the centre and the receiving
antennae on the left and right. The range can be increased by using a directional antenna (e.g. CA 2413, gain approx. 6 dB).
Depending on the cable attenuation you should use antenna amplifiers if the cables are long.
Installation with remote antennae*
see RX A
The CA 2413 planar antenna is connected to the MCW-D 200 control unit and mounted onto a stand with the CA 2462 mounting kit For
more information refer to the "MCW-D Design Guide".
Important:
• There must be an unobstructed path between the microphone units and the antennae. The range is around 30 m. For
optimum range the surface of the table is important, wood or plastic tables are ideal, but metal tables can cause interferences and
reduce the range.
• Please make sure that the minimum distance between the antennae and the microphone units is not less than 1 m.
• Size of the room: up to 400 m
• Number of participants: 30 - 100
• Antenna position: The antennae should be placed as high as possible above the table in a position close to the participants.
• Alignment: Place the antennae so that they point to the participants (the convex side must point to the front).
