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 delayed relative to each other.
For example, if the video portion of a live international broadcast 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 xed 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.

Kachinko System
The KS -1018 is used to produce a synchronized video and audio 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 “clapperboard” 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 factory 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.
Front panel
The front panel contains the following:
PRESET/MANU switches Only one of these switches can be
on (lit) at one time. They determine whether the video threshold 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).
Typically, 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 setting. Push them again to recess them.
