About this Manual
This manual contains operation and configuration instruction for the Extron RGB 192, a universal interface.
About the RGB 192
The RGB 192 is an analog computer-video interface with 300 MHz (-3 dB) video bandwidth and Digital Display Sync
Processing (DDSP™). Figure 1 shows a typical RGB 192 application. The interface accepts a computer video and an
unbalanced computer stereo audio input. It features a local monitor output and an RGBHV, RGBS or RGsB output. The
RGB 192 features horizontal centering and level boost. It also features a balanced, line level stereo or mono audio output.

Typical RGB 192 Application
The RGB 192 allows for furniture and under-desk mounting. It has an external switching power supply for worldwide
power compatibility.
Features
•
Flexible mounting options
— The interface can be mounted under a desk or podium, mounted on a rack, or
through a desk with optional mounting kits.
•
Stereo audio
— The interface outputs unbalanced PC stereo audio as line level, balanced stereo (or, depending on
a DIP switch position, mono).
•
Level (boost) control
— A front panel control compensates for signal losses from long cable runs.
•
Horizontal centering control
— A front panel control allows a horizontal centering adjustment.
•
Sync processing
— Using regular sync processing to allow centering control (H-shift) can create problems with
some digital display devices as a result of the sync delay. The Extron DDSP, ensures proper displays without altering
sync pulse timing or width. The sync processing type is selected via the front panel DIP switches.
•
RGBHV, RGBS, or RGsB outputs
— Select the output format via cabling setup and front panel DIP switch.
•
Serration pulse switch
— This DIP switch-selectable feature adds or strips the serration pulses from the output
signal to make it compatible with digital display devices. Use the serration pulse switch if flagging or bending occurs
at the top of the video display.
