A note about using this video device Some people subjected to stimulation by intense light or rapidly flashing images may experience symptoms of temporary muscle spasms or loss of consciousness. If you experience any such symptoms, stop using this device immediately and seek medical attention. In particular when using this device in a public place or other location where there are large numbers of people, you must take into account people other than the operator, and avoid creating and displaying continuous successions of images that might produce this type of intense stimulation. Korg Corporation accepts no responsibility for any health problem or personal or property damage that may occur to the operator or observers from use of this device in violation of this warning.

Video Signal Standard The krossfour can operate in either NTSC or PAL mode. Use the NTSC/PAL switch to select the correct video standard for your equipment or area. Note that the unit will not operate correctly if the NTSC/PAL switch setting does not match the video standards of your other equipment. Note: “NTSC” is the standard used in Japan and North America. Do not change the NTSC/PAL switch setting while the power is ON. Turn the power off first. The krossfour will not operate correctly with non-interlaced signals. The output signal from copy-protected DVD and video sources may be discolored and noisy. Noise may occur with certain devices or media, depending on their individual characteristics and capabilities.

Features Two-channel video mixer with four source inputs Up to four video sources can be connected to the krossfour, and any of the four sources may be individually assigned to each of the two mixer channels. Simple, intuitive design makes it easy to carry out switching and mixing for a wide variety of applications: video jockeying, video performance, video editing, and more.

Thank you for purchasing the krossfour 4-channel video mixer & switcher. To enjoy long and trouble-free use of this product, please read this manual carefully and operate this unit only as directed.

The crossfader control lets you dynamically adjust the mix between the two video channels in realtime. By selecting different fader curves, you can change the characteristics of the fader and access different types of mixing techniques.

Monitor Output The Monitor output allows you to preview or “audition” any of the video sources, without affecting the mixer output - sort of like headphones for the eyes.

Chroma-key or “Blue-Screen” effects Chroma-key is a type of compositing effect that removes (or “keys-out”) a specific color from a video image, allowing a background video source to show through. Spaceships whizzing past planets, superheroes flying through the air, or the local forecaster standing in front of a changing weather map are examples of Chroma-key effects.

Luma-key effects Like Chroma-key, Luminance-key (or “Luma-key”) is also a compositing effect that removes a specific part of a video image, allowing a background video image to show through. Lumakey uses a brightness value (Black or White) to specify the keyed-out area, instead of a particular color value. For example, white titles prepared on a black background can be made to float on top of any video image by using Luma-key to remove the black areas from the title shot.

Internal Time Base Corrector (TBC) Time Base Correction is needed to provide stable synchronization when working with multiple video sources. TBC digital processing provides excellent synchronization and ensures stable imaging when mixing or switching signals from various DVD players, VCR, video cameras, PCs with video output capability, and other such devices. The switching of input and monitor sources is not image synchronized. This type of switching may cause disturbances in the image.

Switches and Connectors Top Panel

1. INPUT A SELECT keys These keys select the input source for Channel A. When you press a key, it will light up solid to indicate that the source is selected. If the MODE switch is set to C-K (Chroma-key) or L-K (Luma-key), the selected source will be used as the background image for a compositing effect. Press the same key a second time and it will begin blinking. When the key is blinking, the input source will be ignored, and the output of the channel will depend on the MODE setting. If the MODE switch is set to BK (Black) or WH (White), the blinking key indicates that the unit is ignoring the source image and outputting the specified background color instead. These solid backgrounds can then be used as a source for video mixing. If the MODE switch is set to C-K (Chroma-key) or L-K (Luma-key), the blinking key indicates that the input source will be ignored and a black background will be used for the compositing effect. Note: If there is no device connected to the selected input (or there is no signal from the connected unit), the krossfour will output a blue background screen.

These keys select the input source for Channel B. When you press a key, it will light up solid to indicate that the source is selected. If the MODE switch is set to C-K (Chroma-key) or L-K (Luma-key), the selected source will be used as the foreground image for a compositing effect. Press the same key a second time and it will begin blinking. When the key is blinking, the input source will be ignored, and the output of the channel will depend on the MODE setting. If the MODE switch is set to BK (Black) or WH (White), the blinking key indicates that the unit is ignoring the source image and outputting the specified background color instead. These solid backgrounds can then be used as a source for video mixing. If the MODE switch is set to C-K (Chroma-key) or L-K (Luma-key), the blinking key indicates that the input selected for Channel B will be ignored and only Channel A will be output. In the C-K Mode, however, if the HOLD key is pressed while any INPUT B SELECT key is blinking, a black screen will be output for Channel B instead.

2. INPUT B SELECT keys

Note: If there is no device connected to the selected input (or there is no signal from the connected unit), the krossfour will output a blue background screen.

3. HOLD keys There are two HOLD keys; one for each channel. Pressing the HOLD key freezes the image from the selected source (on that channel), so that the image appears as a still. The key acts as a toggle: press it once to freeze the image, and again to return to a moving image. Note that you can change the input source while the image is frozen, but the frozen image will continue to be output until the HOLD key is released. In the C-K mode, the Channel B HOLD key has a special function. When any of the INPUT B SELECT keys are blinking, pressing the Channel B HOLD key will cause Channel B to output a full black screen.

4. Fader Dynamically adjusts the mix between Channel A and Channel B. If the MODE switch is set to C-K or L-K, the fader operates only on the foreground or overlay (Channel B) portions of the image.

5. MONITOR SELECT keys The MONITOR feature allows you to view any input source before it is assigned to a mixer channel. This provides you with the ability to preview, audition or “cue-up” a video source. Use the MONITOR SELECT keys to select which of the four inputs will be sent to the MONITOR OUT jack on the front panel. If you select OUT, the MONITOR OUT provides the same (mixed) signal as the VIDEO OUTPUT jack.

6. Power Indicator Lights up to indicate that the power is on. Note: If this lamp starts blinking, please turn off the power immediately.

1. FADER CURVE switch This switch selects the fader curve. The curve determines how the fader affects the mixing of the two channels. If the MODE switch is set to C-K or L-K, the fader only affects Channel B. (Normal curve) : Sliding the fader causes a gradual, linear change in the mix between the two channels. The center position corresponds to a 50:50 mix. This is a typical crossfade operation; movement in either direction attenuates one channel while amplifying the other. (No mix) : Sliding toward the center attenuates both channels; sliding to either end amplifies the corresponding channel. The two channels never mix. (Center mix) : Channels are mixed only over the central span of the fader range, (Switcher) : The fader acts like a toggle switch that selects either Channel A or Channel B. There is no attenuation and no mixing.

2. MODE switch Selects the background color or the overlay mode. BK (Black): Sets the background color to black. WH (White): Sets the background color to white. C-K (Chroma key): The unit cuts out the blue parts of the (foreground) Channel B image, so that the Channel A signal (background) shows through the cutouts. L-K (Luminance key): The unit cuts out the black and white portions from the (foreground) Channel B signal, so that the Channel A image (background) shows through the cutouts. Note: For C-K and L-K modes, Channel A serves as the background and Channel B is the overlay. Note that when signals are being mixed in these ways, the fader affects only the Channel B image.

3. FINE knob (C-K/L-K Level Adjustment) This control is effective only in C-K and L-K modes. If the mode is set to C-K, this knob will adjust the color of the area that will be “keyed-out” or removed from the foreground image (Channel B). If the mode is set to L-K, this knob will adjust the brightness level (from white to gray to black) of the area that will be “keyed-out” or removed from the foreground image (Channel B).

4. INPUT 4 jack This input accepts a composite video signal.

5. MONITOR OUT jack The signal provided by this output is selected by using the MONITOR SELECT keys.

2. INPUT 1 jack This input accepts a composite video signal. If you connect both the S-VIDEO connector and the INPUT 1 jack, only the S-VIDEO input will be effective.

3. INPUT 2 jack, INPUT 3 jack These inputs accept composite video signals.

4. OUTPUT S-VIDEO connector This output provides the output from the krossfour’s mixer as an S-VIDEO signal. Specifically, this signal will be the signals from Channel A and Channel B (as selected by the INPUT SELECT keys), after they have been mixed and processed by the fader.

5. OUTPUT jack This output provides the output from the krossfour’s mixer as a composite video signal Note: The OUTPUT S-VIDEO connector and the OUTPUT jack both provide the same content. Both outputs can be used at the same time.

6. NTSC/PAL switch This switch is used to select the video standard you are using. Turn the krossfour off to change the setting on this switch. The krossfour reads the setting of this switch when power is first turned on, and the setting cannot be changed until you turn the power off. NTSC: Japan, North America, etc. PAL: Europe, etc. Note: Be sure this switch is set to match the standard of your input signals, or the output signal will be garbled.

7. DC 7V IN Connect the AC adaptor (included) to this jack.

8. Power switch Switches the power between ON and STANDBY.

Operating Procedure 1. Make the connections. Connect the OUTPUT jack, the OUTPUT S-VIDEO connector, and/or the MONITOR OUT jack of the krossfour to the input of the display device(s) - monitor, projector, etc. Connect the output of the source devices (DVD players, cameras, PCs, etc.) to the INPUT jacks of the krossfour. Connect the AC adapter (included) to the DC 7V IN connector, and plug the other end into a power outlet.

2. Turn on the power. Turn the power switch ON.

3. Select and control the image output. Use the INPUT SELECT keys to select an input source for each channel. Slide the fader to the A side to output the source signal selected by the INPUT A SELECT keys. Slide the fader to the B side to output the source signal selected by the INPUT B SELECT keys. Select a different FADER CURVE setting to change the fader’s operating characteristics.

4. Output a still image. Press the HOLD key for either channel to freeze the channel’s input signal and output this frozen image as a still. Press the HOLD key a second time to return to normal output.

5. Output the selected background color from either channel. Either channel can be set to output a black screen image or a white screen image. Choose which Channel will output the background color, and press the currently lit INPUT SELECT key for that channel. The key will start to blink, and the input signal will be replaced by the background color selected by the MODE switch, either black (if the MODE switch is set to BK) or white (if WH).

6. Creating Composite Images Composite images (or “compositing effects”) are special effects that combine two video sources into one image - placing a toy dinosaur in downtown Chicago, for example. Generally, one image is set as the background plate, and portions of the second image appear in the foreground as an overlay. There are two different ways to specify which portions of the foreground image will be keyedout, allowing the background image to show through. Chroma-key effects remove areas of the foreground based on their color. Traditionally, the blue portions are removed, so a subject standing in front of a “blue screen” can be superimposed on any background. Luma-key effects rely on removing the black, white or specific gray portions of the image based on their brilliance, rather than color. When using the krossfour in the Chroma-key (CK) or Luma-key (LK) modes, Channel A will be used as the background plate, and Channel B will be used as the overlay, or foreground image. Here’s how. Select the source for the background image by pressing the appropriate INPUT A SELECT key. Select the source for the overlay (foreground) image by pressing the appropriate INPUT B SELECT key. Use the MODE switch to select the type of compositing effect; either C-K (Chroma-key) or LK (Luminance-key). If you have selected C-K, the blue parts of the foreground image (Chan-

nel B) will be removed. If you have selected L-K, the black or white portions of the foreground image (Channel B) will be removed. In each case, the Channel A image will be visible through the areas that have been removed by the “key” effect. You can adjust the extent of the cut-out area by using the FINE dial. Sliding the fader to the B side will make it easier to adjust the FINE dial setting.
