Preparations and Settings

To genlock the system, input a reference sync signal to the 
input side GENLOCK INPUT connector of this unit. The 
reference sync signal can be an analog HD signal (tri-level 
sync) or an analog SD signal (bi-level sync).
The reference sync signal input to the input side 
GENLOCK INPUT connectors is output from the 
loop-through output side connector (

).When nothing is 

connected to the output side connector, the reference sync 
signal is terminated automatically (75

Ω

 termination).

This unit detects the signal format of the input reference 
sync signal automatically and determines whether that 
signal can be used as reference sync signal, according to 
the current system format.

The following table lists the formats of usable reference 
sync signals.

a

: Yes  –: No

When reference sync signals are not input to this unit, the 
system operates with this unit as the master. The 
camcorder operates in synchronization to reference sync 
signals input from the camera adaptor.

The system is not synchronized when the camcorder is 
operating in a special recording mode or playback mode.

When the system is genlocked, and the H phase of HD/SD 
output from the camcorder is set to ±0, the H phase of 
HDSDI or SDHDI signals output from the OUTPUT SDI 
connectors of this unit matches the phase of reference sync 
signals input to this unit.
The HD/SD switch (one of the OUTPUT SELECT 
switches) can be used to set the H phase of SD analog 
composite signals output from the video output pins of the 
VIDEO OUTPUT and REMOTE connectors, as shown in 
the following table.
