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.
