Extron • Matrix 100 • User’s Manual
General
Each Extron Matrix 100 is custom designed to the user’s specifications. The
configuration is built from various combinations of ten I/O modules. The I/O
modules and possible configurations are listed below. The Matrix 100 can be
controlled from a host computer or from a QuickSwitch Front Panel Controller
(QS-FPC).
Matrix units can also be interconnected to expand the switching capabilities for
up to 48 inputs by 48 outputs. This allows for multiple switching combinations.
I/O Modules Matrix 100 Switchers are ordered for a specific application with a combination of
I/O modules. Each module switches one type of video signal – one for red, one
for blue, etc. One audio module switches both left and right stereo channels.
• 4 x 4 Medium-Resolution Analog Module (MRAM), 175 MHz video bandwidth
• 8 x 4 Medium-Resolution Analog Module (MRAM), 175 MHz video bandwidth
• 8 x 8 Medium-Resolution Analog Module (MRAM), 175 MHz video bandwidth
• 4 x 4 Sync Module
• 8 x 4 Sync Module
• 8 x 8 Sync Module
• 4 x 4 Video Module
• 8 x 4 Video Module
• 8 x 8 Video Module
• 8 x 8 Stereo Audio Module
For example: a Matrix 100 designed to switch RGB, separate horizontal and
vertical sync, and stereo audio will require the following modules: three MRAM,
two Sync and one audio modules.
Configurations Depending upon the configuration of I/O modules (above), the Matrix 100
Switcher can have up to 16 different input/output configurations. The
configuration determines how many modules are required.
• RGsB – Red, Green, (sync on green), Blue
• RGBS – Red, Green, Blue and separate composite Sync
• RGBHV – Red, Green, Blue and separate H&V Sync
• RGsBCv – Red, Green, (sync on green), Blue, and Composite video
• RGsBYC – Red, Green, (sync on green), Blue and S-Video
• RGBSCv – Red, Green, Blue, composite Sync, and Composite video
• RGsBA – Red, Green, (sync on green), Blue, and Audio
• RGBSA – Red, Green, Blue, Sync, and Audio
• RGBHVA – Red, Green, Blue, separate H&V sync, and Audio
• RGsBCvA – Red, Green, (sync on green), Blue, Composite video, and Audio
• RGsBYCA – Red, Green, (sync on green), Blue, S-Video, & stereo Audio
• RGBSCvA – Red, Green, Blue, composite Sync, Composite video, and Audio
• CvA – Composite video, and Audio
• YCA – S-Video with Audio
• Cv – Composite video
• YC – S-Video

Standard Features
• Microprocessor control, with battery backup
• RS-232 control
• RGBS, Video, Audio Breakaway
• Composite and S-Video Genlock
• RGB video delay switching (via RS-232/RS-422)
• 175 MHz bandwidth.
Microprocessor Control The Matrix 100 is programmable from a host system, or from the optional
QuickSwitch Front Panel Controller. It uses memory to store up to eight preset
configurations. The battery backup prevents loss of preset information.
RS-232 Control The Matrix 100 can be controlled by any remote control system or computer with
serial communications capability. Refer to Appendix A for programming
guidelines including a complete listing of RS-232 commands and protocol.
Breakaway The RGBS, Video, Audio Breakaway feature of the Matrix 100 allows the user to
program any Video, S-Video or Audio Channel to be controlled separately
(breakaway), or as a group (follow one or more inputs, or all RGB inputs). A fully
populated RGBS composite video and audio switcher can be controlled as three
separate switchers.
Breakaway provides individual video or audio outputs to follow any one or more
RGBS inputs when switched to an output channel. This makes the Matrix 100
capable of adding audio to any or all RGBS or video channels, as well as
switchable video and audio to follow any switched RGBS channel.
Video Genlock The Matrix 100 features a broadcast quality NTSC/PAL/SECAM Composite
Video or S-Video Genlock for synchronized switching of signals. The Matrix 100
will Genlock as many composite video signals as are installed in the switcher.
RGB Delay Switching The Matrix 100 can be programmed (via RS-232) to delay switching the RGB
video for 1 to 9 seconds after the sync is switched. This allows the display device
to be in sync before the picture arrives, providing seamless switching of the
RGBS signals when switching between various frequencies.
175 MHz Bandwidth Even when fully populated, the Matrix 100 has a bandwidth of no less than 175
MHz (-3 dB).

QuickSwitch™ Front Panel Controller (QS-FPC)
The QuickSwitch Front Panel Controller (QS-FPC) provides local control of all
Matrix 100 Switcher functions. It is supplied as an optional accessory to the
Matrix 100 and is intended for users who wish to supplement normal RS-232
computer control with local or remote operator control. Refer to Chapter 2 for
instructions for mounting the QS-FPC, and to Chapter 4 for operation. The
QS-FPC includes the following features:
Control Microprocessor SmartControlTM is the Front Panel’s built-in
microprocessor. With it, the user determines the Matrix 100 input/output
configuration, what presets are saved, as well as all other switcher settings.
Configuration Memory SmartControl can store up to eight different matrix
configurations (called presets). This can save hours of reprogramming each I/O
configuration. The QuickSwitch Front Panel Controller (QS-FPC) allows for easy
configuration of inputs and outputs, as well as the control of additional system
features.
QuickSwitch SmartControl The Front Panel includes full complement of function
buttons make setup and programming the unit fast and easy.
Redundant Power Supply The Matrix 100 can be ordered with an optional redundant (backup) power
supply to prevent signal loss if input power to the primary power supply should
suddenly be lost or interrupted.
Chapter 1 • Introduction to Matrix 100

Extron • Matrix 100 • User’s Manual 1-4
Sample Configuration
Figure 1-3 shows one example of the I/O modules that could be installed in six
planes of a Matrix 100. See page 1-1 for I/O modules and possible
configurations.
For example, an 8 x 8 RGBS switcher requires: three 8 x 8 medium-resolution
analog modules (MRAM) and one 8 x 8 sync module (Syn). This would occupy
the Red, Green, Blue and one Sync/Video planes. The fifth plane could have a
composite video module (Cv), and the sixth plane could have an audio switching
module (Aud).
This configuration is capable of being
controlled and routed as three
separate switchers:
• one 8 x 8 RGBS matrix switcher
• one 8 x 8 video switcher
• one 8 x 8 audio switcher
In addition, SmartControl™ allows
the Matrix 100 to group these
functions as a single RGBS
composite video switcher with stereo
audio.
The bottom of the diagram illustrates
how the Main Controller (and the
optional QuickSwitch Front Panel
Controller) routes the various inputs
to the outputs.

Multi-Output Connection
When using the Matrix 100 to switch different types of video signals, the signal
output from the switcher is in the same format as the input.
• RGB and Sync (composite or separate H&V) signals will pass through the RGB
and Sync outputs
• NTSC and PAL video signals will pass through the composite video output
• S-Video will pass through the S-Video output (two Video modules)
Therefore, if multiple signal types are used in the same switcher, those same
signals will be available to the output devices.
In the diagram below, the Matrix 100 supplies RGB output for large screen
projectors and data monitors, composite video output for LCD projector and
audio output for a stereo audio system.

Genlock Connections
If so desired, the Matrix 100
can use an external
Genlock signal to
synchronize composite
video or S-Video switching.
The illustration here shows
the Genlock connections.
The In connector goes to a
timing source. The Out
connector allows the signal
to be passed on to another
video device; it does not
have to be connected for
Matrix operation.
Figure 2-2. Genlock connects to a timing source.
RGB Input Connections
All RGB input and output connections to the Matrix 100 are made with BNC type
connectors. Many types of RGB output devices (scan doublers, document
cameras, etc.), including most computers, do not have BNC video output
connectors. If not, a suitable adapter, or an Extron computer-video interface,
should be used to adapt the device output to the BNC input of the Matrix 100.
With the proper adapter, the RGB and Sync signals can be connected directly to
the R, G, B, H, V inputs of the switcher. If the RGB signal is using the Sync-on-
Green channel, connect the RGB cables to the switcher without using the sync
channels.
RGB input connections to the Matrix 100 can be made using the following
combinations:
Without Audio
RGsB - Red, Sync-on-Green, Blue
RGBS - Red, Green, Blue, and Composite Sync
RGBHV - Red, Green, Blue, H&V Sync
With Audio
RGsB with R&L Audio - Red, Green, Blue, and Audio Follow
RGBS with R&L Audio - Red, Green, Blue, Sync and Audio Follow
RGBHV with R&L Audio - Red, Green, Blue, H&V Sync and Audio Follow
The following pages illustrate examples for the above combinations with Right
and Left Audio connections. If audio is not being used, ignore that part.
