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.
