Introduction
About the SGS 408
The Extron SGS 408 is an eight-input, high resolution, component video and
RGB video matrix switcher. It provides seamless cuts, dissolves, wipes, and
titles, as well as scaling capabilities, to bring professionalism and style to live
multimedia events and presentations. The SGS 408 allows analog component
video, RGsB, RGBS, and RGBHV signals to be displayed on a device with a fixed
resolution and aspect ratio, such as an LCD (liquid crystal display) projector,
DLP (digital light processing) projector, plasma display, or DVI (digital visual
interface) device.
The SGS 408 provides up to five outputs. Three of these outputs show the
program output, which is the picture the audience sees. One of these outputs
uses an optional DVI connector. Two outputs show the preview image, allowing
the switch operator to view the images before they are sent to the program
output.
Seamless switching allows switching between sources without a loss of sync.
You can connect the SGS 408 to an Extron RCP 1000 remote control panel. You
can also connect up to three SGS 408 switchers to one Extron ECP 1000 event
control panel.
Features
The SGS 408 provides the following features:
• Executive mode — Locks out all front panel functions. When executive mode is
enabled, all functions are available through RS-232 commands.
• Freeze mode — Locks the output display to the current image. Two freeze
buttons allow independent control of the program and preview images.
• Inputs — Include eight sets of BNC inputs for component video, RGsB (sync
on green), RGBS (composite sync), and RGBHV.
• LCD menu display — Provides access to several menus that control the image
display.
• Memory presets — Provide 16 auto-recall memory locations per input that
store sizing, centering, and filtering information for the incoming
frequency.
• Outputs — Output video as RGBS or RGBHV. Two sets of BNC connectors
and two 15-pin HD connectors are provided. One set of BNC connectors
and one 15-pin HD connector displays the program image, and the other
set of BNC connectors and 15-pin HD connector display the preview
image. In addition, a DVI connector for DVI-D output of the program
image is available as an option.
