The Extron RGB 474xi is a wall-mountable, analog computer-video and audio interface with ADSP™. It allows up to two computer-video inputs with resolutions up to QXGA to be converted for output to projectors and flat panel displays. It also accepts unbalanced computer stereo audio and outputs line level stereo or mono audio. It provides a composite video pass through connector, an S-video pass-through connector, RCA audio connectors, and an RJ-45 connector for network connection. The RGB474xi installs in a standard US three-gang wall box and is ideal for applications that require signal amplification and sync processing to ensure compatibility between many different types of displays and computer-video signal sources found in classrooms, auditoriums, and conference rooms.

The RGB 474xi features Extron Advanced Digital Sync Processing or ADSP technology that provides all-digital processing of sync signals, eliminating compatibility issues encountered when using analog sync processing with digital display devices.
In addition, it includes a buffered local monitor output and video input termination. Level and peaking as well as horizontal shift controls can be accessed via the back and front panels, respectively. Input selection is available via the front-panel or controlled remotely via contact closure.
特性
Input: RGB video on two female 15-pin HD connectors; audio on two 3.5 mm stereo mini jacks
Output: RGB video on two female 5-BNC pigtails; audio on two captive screw connectors
300 MHz (-3 dB) RGB video bandwidth
Compatible with computer-video resolutions up to QXGA
Buffered local monitor output
ADSP™ - Advanced Digital Sync Processing — An exclusive Extron technology that conditions sync signals to provide reliable operation with a variety of signal sources and display types. ADSP reshapes the sync signals, restores proper TTL voltage levels, and maintains the original video to sync timing relationships while allowing centering control.
DDSP™ - Digital Display Sync Processing — Allows the sync signal to pass through without altering sync pulse or width. Disables other sync processing features such as horizontal and vertical centering.
Three-position level/peaking control — Boosts and equalizes video signals to compensate for signal loss and high frequency attenuation that occur in long cable runs.
Horizontal shift control — Shifts the displayed image left or right on the display screen. Also called "horizontal centering".
Two memory settings for centering and horizontal shift control
Active PC audio to balanced audio interfacing — Converts computer-generated, unbalanced audio to balanced line level stereo audio for output on a captive screw connector and two female RCA connectors.
Selectable stereo or summed mono audio output
Includes composite video pass-through connector, RCA to BNC, S-video pass-through connector, 4-pin mini DIN female to female, active stereo/mono, unbalanced to balanced stereo audio driver, and RJ-45 connector for network, data, and phone transmissions
Contact closure remote control
Available in white
Highly reliable, energy-efficient external universal power supply included, replacement part #70-775-01 — Provides worldwide power compatibility, with high demonstrated reliability and low power consumption for reduced operating costs.
Installs in US three-gang wall box
注: Part numbers 60-519-02, 60-519-03 and 60-519-05 have been retired.
