Operation
Connect power cords and turn on the display and audio output
devices (projectors, monitors, speakers), the interface, and the
input device (computer). The system is ready for operation.
The image should now appear on screen, and sound should
be audible. If not, ensure that all devices are plugged in and
receiving power. Check the cabling and switch settings, and
make adjustments as needed.
If problems persist, see Troubleshooting in this chapter. If the
troubleshooting tips do not help, call the Extron S 3 Sales &
Technical Support Hotline.

Level/boost control — The Level/boost control alters the video
output voltage to affect the brightness of the displayed
image. Adjust the knob while viewing the displayed
image to set the level/boost that provides the best picture
quality.
If the interface receives a typical (0.7 volts p-p) analog
computer video input, the output is as follows:
• 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 just before the boost range (indicated
by the red line on the interface, the shaded area on the
illustration on the previous page) to output unity level
video.
