Front Panel Controls and Indicators

All of the scaler’s controls are on the front panel (figure 3-1). Front panel LEDs provide graphic indication of some of the basic system functions. For more complex tasks, such as system configuration, the scaler has a menu system that is operated using the front panel buttons and displayed on the output monitors (figure 3-2).

Video controls

1Input 1 through 4 buttons — The Input 1 through Input 4 buttons select the associated video input to scale (except for input 4 when configured as passive) and display on the output(s). Audio follows (switches with) the front panel video selection.

Input 1 through 4 LEDs — The lit Input 1 through Input 4 LED indicates the video and audio input that is selected.

2Blank button — The Blank button switches the output(s) to a black screen.

Blank turns off the R, G, and B video output signals only; the H and V sync outputs remain active. This ensures that the display(s) retains sync lock.

Blank has no affect on input 4 when it is passive (unscaled).

Blank LED — The Blank LED indicates that the video output is blanked.

3Freeze button — The Freeze button locks the output display to the current image being input. When the freeze function is enabled, the Freeze LED is lit. To unfreeze the image, press the Freeze button again.

When the output is frozen, the video input cannot be removed without losing the displayed image.
