Selecting a Mounting Location 

 
The mounting location of the AudioScience microphone can be determined through the 
application of five principles.  These principles are to be used as a general guide as to locating the 
microphone.  Adherence to these principles will allow the AudioScience microphone to function 
at its highest potential.  If, due to other concerns, the microphone has to be mounted in a less than 
ideal position or manner, it will still function, and may function quite well, but not as well as it is 
capable of. 
 
1.  All desirable seating positions should be within 14 horizontal feet (4.3 meters) of the 

microphone capsule, with an unobstructed line of sight to the microphone capsule. 

 
2.  The supplied hardware is for mounting the microphone to ceilings that are between 8 feet 

(2.4m), and 10.5 feet (3.2m) high.  With those ceiling heights, the bottom of the rear deflector 
will be between 6.5 feet (2m) and 9 feet (2.7m) above the floor.  If the microphone needs to 
be hung in rooms with ceiling heights greater or less than this recommended range, either 
order the 

AudioScience Comprehensive Mounting Kit, 

or arrange some sort of alternative 

mounting system. 

 
3.  All undesirable noise sources should be blocked from reaching the microphone capsule by one 

or both boundaries of the microphone.
