Thank you for your purchase of the Kamesan KS - 6002 integrat-

Kamesan  mixer  units  such  as  the  KS -342  and  extends  their 
capabilities.
The  key  features  of  this  unit  include  switchable  2 - band  EQ  on 
each channel, as well as switchable compression on each chan-

operations.
No  external  power  supply  is  needed  for  the...

equipment (in which case, the KS-6002 becomes the “jam in the 
sandwich” between the KS-342 and another unit such as the KS-
6001 sub-mixer).
THRESHOLD  LEVEL:    Use  these  controls  to  set  the  individual 
threshold levels of the four compressor units for each channel 
of the mixer connected to the KS - 6002.
Since  optimum  setting  levels  will  var y  according  to  the  nature 
of the material, there is no standard setting of the threshold lev-

are  center- detented,  with  a  “click”,  so  that  it  is  easy  for  you  to 
tell, even without looking, when a band is flattened.

Each  channel  has  two  controls  allowing  you  to  set  the  center 
frequency  of  each  band.  The  low  center  frequency  can  be  set 
between 200 Hz and 3.2 kHz. The high center frequency can be
