APPLICATIONS

The RGB 404 is a three gang, universal analog interface that com-

bines the flexibility of a full featured interface with high performance

standards and specifications. It has a 300 MHz video bandwidth, and

provides for the connection of most popular computers to large screen

display products.

Extron’s RGB 404 provides an additional 3.5 mm stereo audio input

connector for desktop or laptop computers with built-in sound card

output. More importantly, the RGB 404 provides audio interfacing

and conversion of low-level unbalanced signals to line-level balanced

audio signals on both the 3.5 mm and RCA audio inputs. The benefit

of balanced audio is that the signal is cleaner and can travel longer dis-

tances.

Extron’s RGB 404 is compatible with computer-video signals with fre-

quencies between 15- 150 kHz including VGA, SuperVGA, XGA,

XGA-2, M

AC, Quadra, SUN, SGI and more. Additionally, the RGB

404 provides pass through connections for composite video, S-Video

and a RJ-45 network connection.

The RGB 404’s modular design fits flush into a wall, podium or table

attaching to a standard, three gang mountable plate. Extron offers a

selection of grey, black or white wall plates to match the surface in

which the RGB 404 is mounted.

Enhancement features include jumper selectable level control and

peaking adjustments which allow for variable distances up to 200 feet

without any reduction in signal quality. When using the RGB 404

with an Extron MBC input cable, it is possible to view the connected

computer’s monitor and the large screen display simultaneously. The

RGB 404 also features a 75 ohm termination switch that allows for

video termination when a local computer monitor is not connected.

FEATURES

n Audio interfacing– Both the 3.5 mm stereo jack input and

left/right RCA connections provide line-level signals to audio dis-

tribution equipment.

n Unbalanced to balanced audio conversion– Unbalanced audio

(from a computer or VCR for example) may be input either into

the 3.5 mm stereo jack and/or left and right RCA connectors, and

converted to line-level balanced audio. The benefit of balanced

audio is the elimination of noise normally associated with unbal-

anced audio when distributed over longer cable runs.

n Computer audio input– A 3.5 mm stereo input is provided for

computer audio sources.

n Horizontal centering– Allows the input computer source to be

shifted horizontally on a presentation monitor or projector screen.

n Pass through connection– The RGB 404 provides pass through

connections for composite video, S-Video and a RJ-45 network

connection.

n Level control– Allows for adjustment of the brightness level of

the displayed image. This control is similar to a brightness control

on a data monitor.

n Peaking– Adjusts the sharpness of the displayed image and com-

pensates for high frequency loss due to cable capacitance and

bandwidth loss.

n Sync output– The RGB 404 has six BNC connectors for

simultaneous RGB composite sync and H&V sync output.

Digital Display Sync Processing (DDSP™)– Sync is output

in its original state ensuring compatibility with LCD, DLP

and Plasma digital displays.

n 75 ohm input termination switch– Offers 75 ohm video termi-

nation for applications where a local computer monitor is not

being used.

n Mountable– The RGB 404 is designed on a three gang plate and

can be mounted into a wall, podium, table or anywhere. Perfect

for permanent installations, the built-in capability of the RGB

404 promotes a more aesthetically oriented and businesslike

enviornement.
