Basic operation
Superimpose is an effect that cuts out the dark portion of an image and places it on 
top of a background image. Use this effect when you want to add text you created 
with your computer or with the P-1 (sold separately).
As an example, here’s how to superimpose text from image “B” into the background 
image “A.”
* The superimpose effect is available only for channel 4.
1
Input a background image into a video input [1]–[3], and input the text image 
into [4].
2
Set the video fader to “A.”
Also use Input Select “A” [1]–[3] to select the background image.
3
Press the Superimpose button.
The Superimpose button will blink.

4
Use Input Select “B” to select the (text) image that you want to add.
Input controller “B” channel 4 will blink rapidly. At the same time, the Superimpose 
button will light.
5
Move the video fader to “B.”
The superimposed image will appear.
6
Use the superimpose level knob to adjust the range that is cut out.
As desired, you can adjust the range of color that will be cut out.

in the procedure described above.

The input selector buttons 
blink in one of two ways 
depending on the function 
you're using.
Blinking slowly
When using a transition time 
knob.The blinking ends after a 
fixed time.
Blinking rapidly
When using a compositing 
effect (P in P or 
Superimpose).The blinking 
continues.
If the Superimpose button is 
lit, using the input selector to 
select a channel other than 4 
for the superimposed image (A 
or B) will automatically 
“suspend” the superimpose 
effect; the Superimpose button 
will blink.
Easily extracted images 
 As the image to be 
superimposed, try to use an 
image that has a clear 
demarcation between dark and 
light areas. This will provide 
the cleanest extraction. 
 If you’re using text, choosing 
white text on a black 
background will provide the 
cleanest extraction.
