Frame Sync: Enables horizontal and vertical
alignment of video signals to a genlock signal.
Effective on both synchronous and asynchronous
signals.
Line Sync: Locks the video signal of within ±1/2H
to a genlock signal. Output delay is 1H. Effective
only when video signal is synchronous to the
genlock signal.
AVDL: Locks the video signal to a genlock signal
with a 1H delay. Effective only when video signal is
synchronous to the genlock signal.
Input Lock: Locks the system to an input video
signal. The delay can be adjusted by System
Phase and/or Frame Delay. However, the minimum
delay is 520clk common in all formats. (HD: 74
MHz, SD: 27MHz) Does not use a genlock signal.

Sets a system format for the FA-9520.
Auto Detect: Detects and sets the detected input
video format to the system format.
Other values make the system work in the format.
Selects which field to be used twice to compose a
frame.
(Effective on composite signal inputs.)
*1 Selecting ODD/EVEN for Forced Field, while FS Input Select(9-2-1) is set to Composite, Synchro Mode
to Frame Sync, and Frame Delay(9-2-3) to 0 frame, the Frame Delay setting value will always reset to 1
frame. Set Frame Delay to between 1 and 8 frames.
*2 Frame Delay (9-2-3) cannot be set if Synchro Mode is set to Line Sync, or AVDL.
*3 Forced Field cannot be set if Synchro Mode is set to Line Sync, or AVDL.
*4 The Freeze function via GPI input is disabled if Synchro Mode is set to Line Sync, or AVDL. See
section 9-5 “GPI” for details.
*5 Changing the Synchro Mode setting will reset 1080 V Phase and 720 V Phase settings in HD Phase
menu and the V PHASE setting in SD Phase menu to their default values according to the set Synchro
Mode.
*6 Switching input signals with a phase difference using a router or such device may cause shock noise to
occur on video or audio signals if the phase difference (compared to the genlock signal) exceeds the
range shown in the following table. If the difference is within range, shock noise will not occur.
*7 This item is disabled if an FA-95CO option is installed and Format Error Trigger in section 9-2-1 “FS
Input Select” is enabled.
Phase difference from genlock signal
-1H (with line differences depending on video format) to +1/2H
-5H (with line differences depending on video format) to +1/2H
