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).
