Chapter 1 • Introduction to the RGB 320 Switching Interface System
RGB 320 Switching Interface System • User’s Manual • Extron
Features
•High bandwidth – The RGB 320 provides a 220 MHz bandwidth for effective
transmission of high resolution computer video and audio signals.
•Central control– The RGB 320 interfaces and switches input sources from buffers
throughout the room to two displays for professional presentations.
•RS-232 control – Allows for third party control system (such as AMX® or
Crestron®) integration via the RS-232 serial port.
•Universal compatibility – The RGB 320 accepts RGsB, RsGsBs, RGBS and
RGBHV video signals, ensuring compatibility with all types of computer inputs.
•Rack mountable – The RGB 320 is housed in a 17 inch wide, 2U high metal
enclosure, with a 19-inch rack-mount face and mounting hardware.
•Digital Sync processing – Provides image stability for all CRT, LCD and DLP
projection devices.
•System diagnostics – Operations are monitored by LEDs on the front panel.
•Peaking – The RGB 320 has peaking control to maintain the original signal
integrity over long cable runs.
•Horizontal & vertical centering – This allows position (shift) control of the image.
•Audio gain & attenuation – Audio levels may be set for each input in increments of
1 dB, from -15 dB to +9 dB.
•Video levels – The RGB 320 provides adjustment for all RGB video levels via the
front panel buttons or remote PC with RS-232 control.
•Memory blocks – Ensures that each computer’s settings are saved, storing
horizontal & vertical centering, audio and video levels.
•Audio follow & breakaway – The RGB 320 allows audio to be switched with video
(follow) or switched separately from video (breakaway).
