Kachinko System
The  KS -1017  is  used  together  with  the  KS -1018  “clapperboard” 
or with other synchronization sources to synchronize video and 
audio  which  may  arrive  via  different  feeds  or  be  otherwise  de-
layed relative to each other.
For  example,  if  the  video  portion  of  a  live  international  broad-
cast  is  transmitted  via  satellite,  and  the  audio  portion  via  sub-
marine cable, there will be a noticeable lag between the two sig-
nals when they arrive at the local broadcast center. In this case, 
the  audio  should  be  delayed  by  a  certain  fixed  amount  before 
broadcast so that the audio and video are in sync. 
The  Kamesan  Kachinko  System  helps  you  to  work  out  exactly 
how  many  milliseconds  (or  frames)  the  audio  signal  must  be 
delayed in order to achieve proper sync.

The  KS -1018  is  used  to  produce  a  synchronized  video  and  au-
dio signal. See the separate manual for details of operation of 
this unit.
Next, at the other end, the KS -1017 is connected to one or two 
audio  feeds  (typically  the  main  and  sub  audio  channels),  and 
its video probe is used to read the screen showing the  “clapper-
board” so that the audio and video signals can be detected.
The  KS -1017  then  computes  the  delay  between  the  audio  and 
the video signals.
The  time  in  milliseconds  or  frames  between  these  signals  is 
then  read  out  and  the  delay  adjusted  appropriately.  Note  that 
the  frame  rate  (NTSC  or  PAL/SECAM)  is  set  at  the  factor y  and 
cannot be changed. The frame rate for the unit is shown on the 
front panel.

Parts of the KS-1018
The layout of the KS -1018 is quite straightforward, but here are 
some  brief  notes  about  the  features  and  controls,  which  will 
help you when operating the unit.

PRESET/ MANU  switches Only  one  of  these  switches  can  be 
on  (lit)  at  one  time.  They  determine  whether  the  video  thresh-
old and gain controls will determine the threshold and gain of 
the signals (MANU) or whether the KS -1017’s preset values will 
be used (PRESET).
T ypically, you can use the PRESET value whenever you use the  
KS -1018 “clapperboard”, but you may need to use the MANU set-
ting when you are using other synchronization sources.
Audio  threshold  (A1)  and  (A2))  controls These  two  con-
trols are push - in/push - out controls. In other words, when they 
are recessed, pushing them allows them to pop out for easy set-
ting. Push them again to recess them.

They control the threshold level at which a signal received at ei-
ther the A1 or A2 jack triggers the unit (as shown by the orange 
indicators).
MONI  SPK  (Audio  monitor  switch) The  KS -1017  contains  a 
small amplifier and speaker that you can use to monitor the au-
dio  signals  received  at  the A1  and A2  jacks.  Set  this  switch  to 
monitor either A1, A2 or neither (OFF). The volume is adjustable 
using a recessed trimmer pot accessible from the side panel.
Data indicators (1st, 2nd, 3rd) This 3 x 3 matrix shows the 
order in which the audio and video signals have been received. 
Each column represents a signal and they are labeled 1st, 2nd, 
3rd.
The top row (yellow) shows whether the signal was received at 
the analog 1 input (A1), the second row (green) shows whether 
the signal was received at the analog 2 input (A2), and the third 
row (orange) shows whether the video signal was received (V).
Millisecond,  frame  and  timeout  indicators Depending  on 
the  setting  made  using  the  millisecond/frame  selector  switch, 
either the millisecond ms (green) or frame FRAME (yellow) indi-
cator lights.
The  red  timeout T.OVER indicator  lights  if  the  time  interval  be-
tween  the  video  and  the  audio  signals  is  too  long  to  be  mea-
sured accurately by the KS -1017.
START  switch Use  this  switch  to  start  the  measurement  pro-
cess. The switch on the video probe has the same effect.
Video  probe  connector  (V- PROBE) Connect  the  supplied 
video  probe  using  this  bayonet- type  connector.  The  twist- ring 
locking lugs are at the top and bottom and the keying notch/lug 
section is at the left of the connector. Push the probe connector 
into place and twist the locking ring clockwise to secure it. Re-
verse the process to disconnect the video probe.
Video gain /threshold controls and indicator Like the audio 
controls, these are push - in/push - out controls. Similar to  an au-
dio compressor, these allow you to select the gain of the video

input  (GAIN),  and  the  level  above  which  detection  will  be  trig-
gered (TH.). 
When  a  video  signal  goes  over  the  trigger  level  set  here,  the 
orange  indicator  beside  the  threshold  control  lights  (as  does 
the probe’s Detect indicator). Use the video level meter to help 
make  the  setting  so  that  the  KS -1018  “clapperboard”  light  (or 
the signal you are using as the clapperboard) triggers the video 
detection.
Video level meter This shows the light level currently being re-
ceived. We suggest that you use the gain and threshold controls 
when you are using a synchronization signal other than the KS -
1018,  so  that  the  “clapperboard”  pushes  the  level  to  the  third 
segment of the meter (the nominal trigger level).
Data selection switch (DATA SEL.) and data selection in-
dicators Use this switch to rotate between up to three measure-
ments  (the  time  lag  between  the  different  signals).  The  green 
indicators  below  the  audio/video  data  indicators  show  which 
measurement  is  currently  selected,  and  the  display  shows  the 
value of the delay of that measurement (or a timeout).
4 - digit  display This  shows  either  the  time  in  milliseconds  or 
frames.
If  the  delay  is  too  long  to  be  measured,  the  display  shows  all 
dashes, and the red T.OVER indicator lights.
Millisecond /frame  selector  switch Use  this  to  choose  be-
tween  displaying  the  delay  in  milliseconds  or  in  frames,  as 
shown by the indicators to the right of the display.
POWER ON and battery indicator Turn unit on and off with 
the POWER switch. 
The  indicator  lights  red  and  flashes  when  the  batter y  power  is 
becoming low.

There  are  two  identical  balanced  female  XLR - type  connectors 
used  for  the  input  of  audio  signals  to  the  KS -1018,  marked 
AUDIO 1  and AUDIO 2.  These  are  wired  1= ground,  2=hot, 
3 = cold. 
Each connector has a mic/line level switch (MIC / LINE), used to 
match the input level with the level of the audio sync signal.
There  is  also  a  female  15 - pin  D - sub  connector,  allowing  the 
connection of the two balanced audio signals as well as a power 
supply. See the specifications for details of how to wire this con-
nector.

There is only one control on the left side (as you look from the 
front). This is a recessed volume control for the internal speak-
er. Use a small Phillips screwdriver to adjust the volume (clock-
wise to increase the volume, counterclockwise to decrease it).
About the case
Thecarr ying case for the KS1018 may hold a few surprises! 
The rear flap can be folded back for access to the XLR connec-
tors for the analog inputs, as well as the MIC / LINE switches.

The  KS -1017  must  be  removed  from  the  case  if  the  combined 
connector is to be used.
The  top  flap  covering  the  control  panel  and  the  video  probe 
pocket  can  be  folded  back  on  itself,  and  used  as  a  stand  to 
prop the KS -1017 up at a convenient angle on a working surface. 
Note  that  you  must  disconnect  the  video  probe  before  closing 
the flap.
Batteries
The KS -1017 uses 4 A A dr y - cell or rechargeable batteries.
These  are  located  in  the  batter y  compartment  accessed  using 
the hinged cover at the top of the unit.
Take  care  that  the  batteries  are  inserted  correctly  with  the  po-
larity correct.
Never mix batteries of different types, or discarded (or partially -
discharged) and new (or freshly - charged) batteries.
Always follow the batter y manufacturer’s instructions for charg-
ing rechargeable batteries. Never attempt to recharge batteries 
which are not designed for this purpose.

Using the KS-1018 with the KS-1017
This procedure should take place in the rehearsal stage of the 
broadcast.
1. Connect the audio signals to sig-
nals  split  off  from  the  main  and 
sub  feeds.  Ensure  that  the  cor-
rect  signal  level  (mic  or  line)  is 
selected.
2. Arrange  for  the  remote  source 
to  turn  on  the    light  and  sound 
using  the MANU  setting  and  the 
on/off  button  on  the  top  of  the 
KS-1018. Set the KS-1017 to the 
PRESET setting.
 You  should  hold  the  probe 
near  the  screen  so  that  the  vid-
eo  should  trigger  (the  indicator 
by  the  video TH.  control  should 
light)  only  when  the  KS-1018 
light  is  on.  Note  that  the  sta-
tus  of  the DETECT  indicator  on 
the  probe  mirrors  the  status  of 
this indicator. Make sure you are 
holding  the  probe  ver y  close  to 
the  part  of  the  screen  where  the  KS -1018  is  displayed,  and 
at  right  angles  to  the  surface  of  the  screen.  If  you  hold  the 
probe  at  the  wrong  angle,  or  too  far  from  the  screen,  stray 
light  can  leak  in,  making  it  difficult  to  obtain  an  accurate 
reading.
Making the measurement
3. When  you  are  satisfied,  ask  the  remote  site  to  start  an  auto-
matic  “clap”.  This  will  start  a  countdown,  shown  by  the  red 
countdown  LED  indicators  beside  the  main  clapperboard 
light. As these LEDs count down, press either the START key 
on the main  unit, or the start button on the probe.
 The START  key  is  lit  while  the  unit  is  seeking  and  timing  the 
signals.
