RGB 190F, RGB 192, and RGB 198 • Introduction
RGB 190F, RGB 192, and RGB 198 • Introduction
Introduction, cont’d
Each RGB interface has two or more model options:
Three RGB 190F models
•
RGB 190FV for PC computers
•
RGB 190FM for Macintosh computers
•
RGB 190FS for SGI computers
Two RGB 192 models
•
RGB 192V for PC computers
•
RGB 192S for SGI computers
These two models are otherwise identical with the exception of
the video input cable supplied.
Two RGB 198 models
•
The RGB 198 provides an AC outlet with two Edison
plugs.
•
The RGB 198 EU provides an AC outlet with two Euro
plugs for European markets.
With the appropriate cable adapters, both of these models are
compatible with Macintosh computer and SGI computers.
Features
Flexible mounting options
— The interface can be mounted
under a desk or podium, mounted on a rack (RGB 198
only), or through a desk with optional mounting kits.
Stereo audio (RGB 192 and 198 only)
— 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.
Extron’s DDSP (Digital Display Sync Processing), ensures
proper displays without altering sync pulse timing or
width. The sync processing type is selected via the front
panel DIP switches.
Introduction
About this Manual
This manual contains information about the Extron RGB 190F,
RGB 192, and RGB 198 universal interfaces, detailing how to
operate and configure them. The three interfaces are
functionally identical, with the exception of the audio
capabilities of the RGB 192 and RGB 198. All interfaces are
described in this manual; differences are noted where they exist.
About the RGB 190F, RGB 192 and RGB 198
The RGB 190F, RGB 192, and RGB 198 are analog computer-
video interfaces with 300 MHz (-3 dB) video bandwidth and
Digital Display Sync Processing™ (DDSP™). Figure 1-1 shows
a typical RGB 198 application; as noted above, the RGB 190F
and the RGB 192 have a similar setup. The interfaces accept a
computer video and an unbalanced computer stereo audio
input. They feature a local monitor output and an RGBHV,
RGBS or RGsB output. The interfaces feature horizontal
centering and level boost. The RGB 192 and RGB 198 also
feature a balanced, line level stereo or mono audio output.

RGB 198
Table/Rack-Mountable
Interface w/ MAAP Openings
Figure 1-1 — Typical RGB 198 application
All three interfaces allow for furniture and under-desk
mounting. The RGB 198 is rack mountable as well. The
RGB 190F and RGB 192 have external switching power supplies
for worldwide power compatibility, while the RGB 198 provides
an internal power supply.
