RIEF DESCRIPTION

 

The CTK38 is composed by a VHF transmitter (

CST38

) and a power supply (

PSP910

). 

The CST

38 transmitter has been especially designed to allow best usage of MicroEar’s family 

“in

-

ear  receivers”

  and  many  modulation  parameters  such  as  deviation,  level/frequency 

curve,  compression  factor  has  been  optimized.  Therefore  CST38  assures  maximum 
performances  of  MicroEar  both  as  sound  quality  and  as  audio  level  (in  any  case  limited 
because of the very small size of receiver). 
Higher power transmitter are available to further increase the coverage area (cell); it is also 
possible to link in parallel several transmitters (in iso-frequency mode) to create a multiple 
cells coverage. 
MicroEar  internal  battery  has  about  30  hours  working  autonomy;  in  any  case  the  original 
battery once activated (taking out metal label) has a limited life even in power off. 
When empty battery, MicroEar will drastically reduce audio level and receiver sensitivity.
