Setup Guide —­ RGB 580xi

•At the minimum level setting (the counterclockwise limit of this control), the interface outputs video at 0.5 volts p-p.

•Unity level is 0.7 volts p-p, the same as the input signal. Set the control to approximately one-half turn between the minimum and maximum level settings to output unity level video.

•At the maximum level setting (the clockwise limit of this control), the interface outputs video at 1.45 volts p-p.

Select a level setting of 0.7 volts or above to compensate for the decrease in signal level that occurs when the signal passes through long cables. Set the level at the maximum setting for cable lengths over 500 feet for all computer signals of 15 kHz to 135 kHz.

2.Peaking control — The Video Output Peaking control affects the sharpness of a picture. Increased peaking can compensate for detail (mid- and high-frequency) loss from low bandwidth system components or capacitance in long cables.

•The minimum setting (at the counterclockwise limit) provides no peaking.

•The maximum setting (at the clockwise limit) provides 100% peaking.

Adjust this control while viewing the displayed image to obtain the optimum picture sharpness.

Operation

Turn on the input devices (computer, audio device) and output device(s) (projector, monitors, speakers). After powering up the RGB 580xi, the image should now appear on the screen, and sound should be audible. If you are experiencing problems, please refer to the “Troubleshooting” section of the user’s manual.
