Adjusting and Using the Cross-fader Curves
The krossfour is the first video mixer to incorporate a DJ mixer style cross-fader. This cross-
fader features four different fader curves that can be adjusted by a switch located in the left
area of the front panel…
From the left…
Curve 1 – Allows for smooth transitions between channels, and begins blending sources
from the instant you move the cross-fader.
Curve 2 – Mix fades to black at the center position of the cross-fader, and then fades the
second channel in.
Curve 3 – Allows for smooth transition between channels 1 and 2, but doesn’t begin the
blend until the cross-fader has reached the center position.
Curve 4 – This curve can be used for abrupt switching and transform-type effects between
the channels without fade-ins or fade-outs.
Fading to Black or White
The krossfour allows you to fade a source to a black or white screen…
Fade to Black:
1. Move the mode switch located on the front panel to position 1, labeled B.
2. Select your video source for channel 2, and move the cross-fader to the far-right position.
3. For channel 1, press any of the input select buttons twice so that the red light blinks.
4. Move the cross-fader to the left, and the video source on channel 2 will fade to a black screen.
Fade to White:
1. Move the mode switch located on the front panel to position 2, labeled W.
2. Select your video source for channel 2, and move the cross-fader to the far-right position.
3. For channel 1, press any of the input select buttons twice so that the red light blinks.
4. Move the cross-fader to the left, and the video source on channel 2 will fade to a white screen.
Using the Chroma Key Function
The Chroma key function allows the krossfour to ignore blue in a video source, and allows
the second channel to pass through in the blue areas…
1. Select two different input sources for channels 1 and 2 - make sure that the channel 2 source has blue in it.
2. Move the cross-fader to the far-right position.
3. Move the mode switch located on the front panel, to position 3, labeled C-K.
4. Using the fine-tune knob located on the front panel, eliminate or key out blue from the channel two source.
You will see the image from channel 1 passing through, but only where blue used to be.
