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 userdefined 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 Windowsbased 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.

Installation and Operation Overview
To install and set up an RGB 324, RGB 326, or RGB 340 buffer,
follow these steps:
Determine the installation location.
1
Prepare the site for installation. Use the template supplied
2
in the appendix to mark the site, then cut out the
wallboard or wood.
Set the jumpers. The jumpers will be inaccessible after
3
installation.
Connect cables to the buffer for power and for audio and
4
video output. These cables will be inaccessible after
installation.
Set the front panel High Z/75 Ohm video termination
5
toggle switch.
Temporarily connect input cables and apply power to the
6
buffer, the RGB 320, and the input and output devices. See
the “Pre-installation testing/troubleshooting” section in
this manual.
Temporarily disconnect power. Remove cables as needed,
7
and mount the buffer to the wall or furniture.
Reconnect cables and power, and adjust centering and
8
levels as needed.
1. Cut out the center portion of the cut-out template, which is
provided in appendix B.
2. Place the template (or the wall box) against the installation
surface, and mark the guidelines for the opening on the
wall or furniture.
3. Cut out the material from the marked area with a jigsaw or
small hand saw.
4. Check the opening size by inserting the wall box (if used)
or the interface (if no wall box is used) into the opening.
The box and/or interface should fit easily into the opening. Enlarge or smooth the edges of the opening if needed.
5. Attach the wall box to the wall stud or furniture with nails
or screws, leaving the front edge flush with the outer wall
or furniture surface, as shown in the following illustration.
2-2
Installation and Operation Instructions
Preparing the site, installing the wall box
(RGB 324, RGB 326)
When selecting an installation site, choose a location that will
allow cable runs without interference, preferably next to a
2” x 4” wall stud or a structural element of the furniture. Allow
enough depth for both the wall box and the cables. You may
need to install the cables into the wall, furniture, or conduits
before installing the buffer.
The RGB 324 and RGB 326 are typically installed in a 2-gang,
3.5-inch deep, metal wall box (provided by Extron). A different
wall box, a plastic box, or no box at all can be used, as long as
the installation conforms to electrical codes and to the
interface’s size requirements. Dimensional drawings and
actual-size cut-out templates are provided in appendix B.
RGB 324/326/340 • Installation and Operation
Attaching the wall box to a wall stud
If attaching the wall box to wood, use four #8 or #10
screws or 10-penny nails. A minimum of 1/2 inch
(1.3 cm) of screw threads must penetrate the wood.
If attaching the wall box to metal studs or furniture, use
four #8 or #10 self-tapping sheet metal screws or machine
bolts with matching nuts.
6. Feed cables through the wall box punch-out holes for
connection to the buffer, and secure them with cable
clamps to provide strain relief.
7. Exposed cable shields (braids or foil) are potential sources
of short circuits. Trim back and/or insulate shields with
heat shrink.
