About this Manual

This manual contains information about the Extron RGB 190F
universal interface and the RGB 192 universal interface with
audio, detailing how to operate and configure them. The two
interfaces are functionally identical, with the exception of the
RGB 192's audio capabilities. Both interfaces are described in
this manual; differences are noted where they exist.

About the RGB 190F and RGB 192

The RGB 190F and RGB 192 are analog computer-video
interfaces with 300 MHz (-3dB) video bandwidth and Digital
Display Sync Processing™ (DDSP™). Figure 1-1 shows a
typical RGB 192 application; the RGB 190F application is
identical with the exception that it does not have audio
capabilities. 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 also features a balanced, line level stereo or mono audio
output.

The interfaces are furniture mountable and have an external
switching power supply for worldwide power compatibility.
There are three RGB 190F models: RGB 190FV for PC

190FS for SGI computers. There are two RGB 192 models: RGB
192V for PC computers and RGB 192S for SGI computers. The
models are identical with the exception of the video input cable
supplied.

Features

Flexible mounting options — The interface can be mounted
under a desk or podium, or mounted through a desk or
other furniture with optional mounting kits.
Stereo audio (RGB 192 only) — The interface outputs
unbalanced PC stereo audio inputs as line level, balanced
stereo (or, depending on a DIP switch position, mono)
audio.
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 a front
panel DIP switch.
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.
