KS-6002 EQ Compressor
Thank you for your purchase of the Kamesan KS - 6002 integrat-
ed  4 - channel  EQ  unit  and  compressor,  which  integrates  with 
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-
nel, which can be linked between adjacent channels for stereo 
operations.
No  external  power  supply  is  needed  for  the  unit—power  is 
drawn through the integrated connector when it is mounted on 
the Kamesan mixer.
NOTE
This unit cannot be used in standalone operations. It is only 
suitable for use with other Kamesan products, such as the KS-
342 or KS-6001 mixers. Use or attempted use with any other 
unit will invalidate the warranty.
Notes and warnings
Follow the common - sense precautions below:
Do not allow liquids to come into contact with the unit 
or be spilled inside. Should this occur, fire, damage or 
malfunction may result. 
Make sure that no metal objects or easily inflammable 
substances inadvertently get inside the unit through holes 
or slots. Should this occur, fire, the unit may become 
damaged or start to behave erratically. 
Do not attempt to disassemble the unit, as damage or 
malfunction may result. 
Notes on the Operating Environment
Avoid  using  this  unit  in  places  with  high  heat  or  high  humid-
ity  as  damage  or  malfunction  may  result.  When  using  in  an 
exceptionally  cold  environment,  batter y  service  life  may  be 
shortened,  and  there  may  be  a  drop  in  performance.  If  at  all 
possible, use this unit in the temperature range as indicated in 
the specifications.
When connecting this unit to external devices, be sure to read 
all related operation manuals and connect the devices correctly 
to each other. If there are mistakes in the connections, it is pos-

sible  that  either  the  KS - 6002  or  the  other  unit(s)  will  be  dam-
aged. 
In  the  event  that  smoke  or  odors  come  from  the  unit,  turn  off 
the  power  and  remove  all  batteries  and  external  power  supply 
sources at once. Contact your dealer or service representative. 
In the event of damage or injur y caused by accidents, improper 
operation  or  functioning,  the  proper  course  of  action  shall  be 
determined  according  to  our  service  regulations.  Please  note 
that we cannot be responsible in any way for any loss of pre - re-
corded material.

LEVEL controls
The KS - 6002 unit has the following features when viewed from 
the left side:
Unit release lever: There is a corresponding lever on the right 
side  of  the  unit.  Slide  these  levers  to  the RELE.  position  when 
attaching and detaching the KS - 6002  to and from another unit 
mounted above the KS - 6002 (e.g. a KS - 6001 sub - mixer). Leave 
this lever in the LOCK position when the KS - 6002 is attached to 
the KS - 6001 or the other unit.
When  using  the  KS - 6002  with  the  KS -342  or  another  unit  at-
tached  below  the  KS - 6002  using  the  bottom  connectors,  use 
the  unit  release  levers  of  the  other  unit,  not  those  of  the  KS -
6002, to attach and detach the KS - 6002.
NOTE
The KS-6002 always should be placed above at least one other 
Kamesan unit when fitted in a stack of such units. Although 
some such units have retractable connectors, the KS-6002 lower 
connector cannot retract, and there is therefore a danger of 
damage if it is left protruding below the unit. You should also note 
that there is also a plate on the top surface of the KS-6002 which 
can be removed and used to connect the KS-6002 to other

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-
el. Accordingly, you should find the optimum setting point while 
auditioning the signal you will be recording or broadcasting).
Note that the compression takes place post- EQ, so you should 
probably  make  the  EQ  settings  before  adjusting  the  threshold 
of the compressors. 
Basically,  you  should  make  the  setting  when  a  slightly  higher 
than  normal  level  is  encountered,  and  when  the  compression 
indicator  of  the  channel  (on  the  front  panel)  starts  to  turn  or-
ange. When the knob is in the 12 o’clock position, the threshold 
level is 8 dB higher than the standard 0 dB level. 
The threshold can be set between 0 dB and +12 dB. The attack 
time is fixed at 3 ms, and the release time at 300 ms. Neither of 
these values can be altered.
Front Panel Features
The  front  panel  is  where  most  of  the  action  on  the  KS - 6002 
takes place.

quencies  to  be  cut  or  boosted  by  up  to  12 dB.  These  controls 
are  center- detented,  with  a  “click”,  so  that  it  is  easy  for  you  to 
tell, even without looking, when a band is flattened.
Equalizer  band  frequency  select  controls  (per  channel) 
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 
set between 1.2 kHz and 15 kHz.
EQ  ON  switch  (per  channel)  Each  channel’s  EQ  circuit  can 
be switched into (switch is up) and out of (switch is down) the 
signal path using this switch.
Compressor  ON  switch  (per  channel)  Each  channel’s  com-
pressor can be switched into (switch is up) or out of (switch is 
down) of the signal path using this switch.
Compressor  indicator  (per  channel)  These  indicators  light 
when  the  compressor  is  switched  into  the  signal  path  and  the 
input signal exceed the threshold (that is, the compressor is in 
operation).
Compressor LINK switch (per channel pair) Links odd - and 
even - numbered  channels’  compressors  (1-2,  and  3 - 4),  so  that 
when a signal is received at either channel of the pair that goes 
above the threshold for that channel, both channels’ compres-
sors are triggered together.
Power  indicator  (only  one)  Shows  that  the  equipment  pow-
ering  the  KS - 6002  is  switched  on  and  supplying  power  to  the 
KS - 6002.
Note that the KS-6002 does not have its own power switch. 
Power is supplied only through the connector linking the KS-
6002 to the other unit. 
Also  note  that  when  a  signal  is  passed  through  the  KS - 6002 
with both EQ and compression active, batter y consumption on 
the “host” unit is about 1.5 times that when no signal is being 
passed  through.  Equalization  does  not  use  batter y  power  to  a 
significant  degree,  but  if  you  wish  to  extend  the  batter y  life  of 
the “host” unit, turn the compression off for all channels where 
it is not needed.

About Kamesan
Sigma Systems Engineering was started in 1972 to develop and design 
professional mixers for studio and remote broadcast applications.
Today,  following  the  “slow  and  steady”  principle  of  the  tortoise,  we 
have  built  up  our  sales  and  our  reputation  to  the  extent  that  we  now 
enjoy 95% of the Japanese portable mixer market.
We have concentrated on two or three main areas in our design philos-
ophy: compactness, in an industr y which was traditionally dominated 
by large, heavy equipment; ease of use, since time is always of the es-
sence in the environments where our products are used; and quality, 
to match the needs that today’s broadcasters require.
Our head office is in Shinjuku, Tokyo, and as a small company, we are 
happy to listen to the ideas for product improvement suggested by you, 
the customers and users of our equipment.
Making steady progress (like a tortoise, but maybe a little faster!), we 
hope to meet your requirements, now and in the future.
Visit  both  of  our  Web  sites  at  http://www.kamesan.co.jp  and 
http://www.kamesan.info  in  order  to  find  out  more  about  what  we’re 
doing,  and  to  let  us  know  what  you  are  doing  with  Kamesan  prod-
ucts.
