About this Manual
This manual contains information about the Extron RGB 470xi
series of universal wall, furniture and floorbox mountable
interfaces, and on how to configure and operate them. Unless
otherwise noted, “interface” will be used to refer to all models
interchangeably.
For information on installing the wall box-mountable versions of
these interfaces, refer to one of the available installation guides.
For wall or furniture mount installations (and EC versions), refer
to #68-636-03. For Steel City
® floorbox installations, refer to
#68-636-01. For FSR floorbox installations, refer to #68-636-05.
About the RGB 470xi xi xi xi xi Series of Interfaces
The Extron RGB 472xi (all), RGB 474xi, RGB 478xi, and
RGB 478 Mxi are compact, wall box-, or floor box-mountable
computer video interfaces. Each interface comes in either a two-
gang (RGB 472xi), three-gang (RGB 474xi and RGB 478 Mxi), or
four-gang (RGB 478xi) wall box size, except floorbox models.
Optionally, the two- and four-gang interfaces (except Steel City
and FSR models) come in an EC version which mounts in a
European style wall channel. The interfaces (except Steel City
and FSR models) are also wall/furniture-mountable and come
with a matching mud ring kit (part #70-086-xx). The RGB 474xi
provides an active stereo/mono, unbalanced to balanced stereo
audio driver and an RJ-45 connector for network, data, and
telephone transmissions. The interfaces have a 300 MHz (-3dB)
video bandwidth.
Each interface accepts two 15-pin HD computer-video inputs
and two stereo audio inputs. All models include a 15-pin HD
buffered local monitor output.
Features
Horizontal shifting control — The displayed image may be
shifted to the left or right by turning a front panel knob.
Advanced Digital Sync Processing™ (ADSP™) — ADSP
allows sync processing operations, such as horizontal
centering, to occur without affecting the signal’s sync
timing. This allows horizontal centering to be applied to
signals that are output to digital display devices such as
LCD projectors and plasma displays. A rear panel DIP
switch provides another option, Digital Display Sync
Processing™ (DDSP™), to ensure proper displays
without altering sync pulse timing or width.
Stereo audio — Unbalanced stereo audio inputs can be output
as balanced or unbalanced, unamplified stereo or mono.
