Introduction

About the RGB 324, RGB 326, and RGB 340

Interface Buffers

The Extron RGB 324, RGB 326, and RGB 340 interface buffers

distribute analog computer video and audio signals to the

RGB 320 switching interface system. These buffers each offer a

300 MHz (-3dB) video bandwidth. They provide remote input

connections to the RGB 320 interface for permanent installations

in environments such as conference and training rooms or

command and control centers.

Each buffer accepts one analog RGBHV, RGBS, RGsB, or RsGsBs

computer-video input on a 9-pin D connector, and one

unbalanced stereo audio input on a 2-channel stereo jack.

The RGB 324 and RGB 326 are available in grey, black, and

white. The RGB 340 is available in grey only.

Features

Automatic setup with input signal detection — When an input

(buffer) is selected, the RGB 320 detects the computer type

and scan rate, and loads the appropriate picture settings.

Ten of the most popular computer scan rates and signal

types are factory stored in the RGB 320’s memory, so it is

usually not necessary to make adjustments. If

adjustments are required, the RGB 320 has fifteen

additional memory blocks per input for storing user-

defined picture control settings that are specific to the

installation, so it is not necessary to make adjustments

each time an input is selected.

Furniture and wall mountability — The RGB 324 and RGB 326

buffers have two-gang wallplates for installation on a

wall or in furniture. The RGB 340 buffer is a shelf- or

furniture-mounting version of the RGB 324 with

mounting ears instead of a wallplate.

Additional control methods — The buffers can be controlled

via the RGB 320 front panel buttons or through an

RS-232 device using simple commands or Windows-

based control software.

Monitor termination — Each buffer has a high impedance/

75 ohm termination switch.

Stereo audio — Unbalanced stereo audio inputs can be output

as balanced or unbalanced stereo audio.

Additional RGB 324 and RGB 340 features

“Show Me/Select” button — Each RGB 324 and RGB 340 buffer

has a “Show Me/select” button that allows a user to select

that buffer as the source of the active input to the RGB

320.

Centering and level controls — Adjustments to horizontal and

vertical centering and to video and audio levels for that

input can be made directly from the RGB 324 and

RGB 340 front panel control knobs. Adjustment settings

for each buffer are stored in the RGB 320’s memory.
