12 EDITING SYSTEM PHASE ADJUSTMENT

 

 

 

12-3 DUBBING LOOP FUNCTION

 

 

The dubbing loop function allows you to effectively perform analog video signal adjustment.

The dubbing loop function loops video signals and generates color bar signals from the built-in signal generator.

The picture passes through the looped video signal circuit and is fed back and stored in the memory circuit. Then,

instead of outputting color bar signals from the signal generator, the picture stored in memory is output and

passed through the looped video signal circuit the designated number of times. The same effect is obtained each

time this pseudo-dubbing is repeated and the video signal can be adjusted according to the picture output.

Note

 

 

 

 

• For the dubbing loop function, use the composite video signal.

 

 

1.Connect the rear panel's video input connector and video output connector with the cable.

2.Set menu switch No. 620 <DUBBING LOOP> to activate the dubbing loop function.

OFF (0) : The dubbing loop function is disabled.

3 TIMES (1) : The dubbing loop function repeats 3 times.

5 TIMES (2) : The dubbing loop function repeats 5 times.

10 TIMES (3) : The dubbing loop function repeats 10 times.

• When the menu switch is set to any position except OFF (0), the Dubbing Loop mode is activated.

3.While referring to the color bar on the monitor, adjust the video control parameters so that color changes in the picture are minimized.

4.To end the dubbing loop mode, set menu switch No. 620 <DUBBING LOOP> to “OFF (0)” and press the [SET] button.Normal operation is restored.
