Beyerdynamic Stereo Amplifier CA 2441 User Manual

CA 2441  
Antenna Amplifier  
DESCRIPTION  
The CA 2441 antenna amplifier is used as a signal amplifier for  
the MCW-D 100 / 200 conference systems.  
Due to local conditions the following values are only  
recommendations:  
For the CA 2430 cable (Ecoflex 10) one CA 2441 RT antenna  
amplifier is recommended, if the cable is longer than 25 m  
(CA 2441 RT is mounted to the antenna).  
For the CA 2420 cable (Aircell 7) one CA 2441 RT antenna  
amplifier is recommended, if the cable is longer than 15 m  
(CA 2441 RT is mounted to the antenna).  
These recommendations are only valid, when the distance  
between microphone units and transmitting/receiving  
antennae does not exceed 15 m.
