Connections and Setup

1. Connect a composite or S-Video out from any video source(s) such as a VCR, DVD player, laptop computer,
video camera, TV, etc. to any of the 4 video inputs (S-Video only to input 1) on the krossfour.

2. Connect the main out (composite or S-Video) to your main video monitor.

3. Connect monitor out (composite) located on the front panel, to the video monitor you will use for cueing video
sources.

4. Select NTSC or PAL format (USA standard is NTSC, PAL is usually Europe) by setting the switch on the rear
panel to the proper setting.

5. Power-up the krossfour and your video source(s).

Selecting an Input for a Channel

Located in the center area of the krossfour’s top panel are 2 groups of buttons. Each group
is labeled 1, 2, 3, and 4. These button groups are positioned at each side of the cross­fader…

1. Simply press the buttons for the corresponding video sources that you want to place on each channel or side
of the cross-fader. When an input is selected the button will glow red

Note: The same video source can be used for both channels at the same time – more about this later.

Note: When a video source is selected for an input that is not connected, you will see a blue-screen.

Note: When an input button is pressed twice it will blink, and you will see a black screen.

Selecting a Source to Monitor

Located on the top panel of the krossfour is a row of buttons labeled 1, 2, 3, 4, and OUT.
This is the Monitor Select section. When a video monitor is connected to the monitor output
(located on the front panel), any of the 4 inputs or the main output can be viewed, allowing
you to “cue” up to specific points of a video source…

1. Press the button for the corresponding video source that you want to monitor in the monitor select section.
When a source is selected the button will glow red.

Note: The monitor out can be treated as a 3rd output for the krossfour, if OUT is selected in the monitor

select section.

Holding or Freezing a Source

Located below each of the two input groups for each channel is a HOLD button. This will
freeze any incoming source on the specified channel…

1. Press the HOLD button on either channel when a source is being viewed through it. The image will freeze and
the button will glow red. To release the frozen image press the button again.

Note: Tapping the HOLD button to match an audio source tempo will create freeze-frame/stutter type

effects with the video source.
