4.  The microphone should be mounted far enough away from the videoconferencing system such 

that one or both boundaries of the microphone are between the microphone element and the 
loudspeakers of the videoconferencing system to prevent coupling of the direct sound from 
the speakers into the microphone element.

5.  The mounting holes of the microphone boundary must be directly under a ceiling track to 

allow for mounting hardware. Additionally, to allow for easier changing of lighting tubes or 
bulbs, the microphone should not be mounted where the microphone blocks these items.  If, 
due to acoustic concerns, a light fixture has to be “blocked” then string the microphone cable 
in such a way as to allow for removal of the microphone when light bulbs or tubes need to be 
changed. 

 
6.  If more than one microphone is to be used, consult your TANDBERG Dealer for 

recommendations on mounting locations of the AudioScience microphone.  TANDBERG has 
available a document 

The TANDBERG AudioScience Microphone: Theory and Operation

which can be helpful in understanding the issues involved with operating in a multiple 
microphone environment.
