Connecting External Devices
This camera recorder is equipped with a genlock input
terminal on the side.
Synchronizing signals can also be input from a KA-M790G
unit (Multicore Remote Adapter: sold separately) that is
connected to the accessory connection terminal (68 pin) at
the rear of the camera recorder.
The following describes the case of signal input using the
side [GENLOCK INPUT] terminal.
Input the external synchronizing signal from the
[GENLOCK INPUT] terminal, and synchronize the camera
recorder’s video and playback images with the external
signal.
You can also adjust the H (Horizontal) phase of the camera
recorder’s video signals with respect to the external
synchronizing signals on the [Genlock Adjust] screen of the
[Others] menu. (A Page 96)
Only horizontal (H) and vertical (V) genlock are supported.
The camera recorder does not come with an SC (subcarrier)
lock function.

The genlock function can only be used in the Camera
mode. It is not available in the AUX mode (U model only)
and Media mode.

appears on the
screen.
After locking to the external synchronizing signal is
complete, the display disappears and recording can be
performed.
Note :
When the frame rate is set to 30p, 60p, 60i, or 24p in the
[Frame & Bit Rate] item of the [Record Format] menu, 59.94 Hz
synchronizing signals (vertical synchronization) are input.
50 Hz/60 Hz synchronizing signals are not synchronized.
When the frame rate is set to 25p, 50p, or 50i in the
[Frame & Bit Rate] item of the [Record Format] menu, 50 Hz
synchronizing signals (vertical synchronization) are input.
59.94 Hz/60 Hz synchronizing signals are not synchronized.
Do not connect or disconnect the input cable for the
synchronizing signals during recording or playback.
If the power is turned ON during input of external
synchronizing signals, vertical oscillation may occur. This is
not a malfunction.
Signals such as VTR playback signals with jitters may not be
synchronized.
The camera recorder does not come with an SC (subcarrier)
lock function. Color flash may occur during switching such as
when composite signals are used by a switcher.
