The  microphone  has  been  designed  to  secure  high  frequency  clarity  and  speech  
intelligibility under most conditions.  

The low frequency response is to some extent dependant on the area of the boundary. 
However, for speech pick-up even small areas like podiums are adequate.

The microphone can be placed in essentially any position on the surface, even close to the 
edge. However, try to avoid a placement that may receive reflections from vertical faces as 
this may cause coloration of the sound (comb-filtering). 

For  tables  longer  than  6  m  (20  ft),  it  is  recommended  to  use  more  than  one 
BLM4060.
