Introduction

About the Matrix 50 Series Switchers

The Extron Matrix 50 Series Switchers are broadcast quality, upgradeable matrix
switchers that distribute any video and/or audio input to any combination of
outputs. The matrix switchers can route multiple input/output configurations
simultaneously.

The modular Matrix 50 series are assembled from individual modules, each of
which supports a discrete video or stereo audio plane, as follows:

• Composite video Matrix 50 switchers are assembled around one video
module. The audio version of the composite video matrix requires a separate
audio module.

• S-video Matrix 50 switchers are assembled around two video modules (one
for the luma (Y) plane and one for the chroma (C) plane). The audio version
of the S-video matrix requires a separate audio module.

Matrix 50 switchers with two video modules can also be used to switch two
planes of composite video. If used in this way, the two planes cannot be
broken away; both inputs must be routed to the same outputs.

• Component video Matrix 50 switchers are assembled around three video
modules (one for the luma (Y) plane, one for the red minus luma (R-Y) plane,
and one for the blue minus luma (B-Y) plane. The audio version of the
component video matrix requires a separate audio module.

Component video Matrix 50 switchers can also route RGsB and RsGsBs video
signals up to 150 MHz bandwidth. Switchers configured for component
video can also route multiple composite video planes or S-video and
composite video. If used in this way, the various planes cannot be broken
away; all inputs must be routed to the same outputs.

• Audio only Matrix 50 switchers are assembled around one audio module for
the stereo audio plane.

The video and audio modules are available with differing numbers of inputs and
outputs to support four matrix sizes:

• Eight inputs by four outputs

• Eight inputs by eight outputs

• Twelve inputs by four outputs

• Twelve inputs by eight outputs

The audio switching can either be linked with the video (audio follow) or
independent of the video (audio breakaway). Adjustable audio gain and
attenuation compensates for level differences between audio inputs.

The Matrix 50 Series are expandable single box solutions to simple 150 MHz (-3dB)
routing applications. Each input and output is individually isolated and buffered,
and any input(s) can be switched to any one or all outputs with virtually no
crosstalk or signal noise between channels.

The switchers are housed in rack-mountable, 2U high, 19” wide metal enclosures.
The appropriate rack mounting kit is included with each switcher. Each model has
an internal 100VAC to 240VAC, 50/60 Hz, 30 watts, auto-switchable power supply
that provides worldwide power compatibility.

Figure 1- 1 — A typical Matrix 50 Series Switcher application

Inputs — These switchers offer 8 or 12 RGBS, RGsB, RsGsBs, HDTV, component

video, S-video, or composite video inputs on BNC connectors.
Stereo audio can be balanced or unbalanced, on 3.5 mm, 5-pole captive screw

terminals (audio models).

Outputs — 4 or 8 RGBS, RGsB, RsGsBs, HDTV, component video, S-video, or

composite video outputs are available on BNC connectors.
Stereo audio, balanced or unbalanced, on 3.5 mm, 5-pole captive screw

terminals (audio models).

Bandwidth — Bandwidth is a minimum of 150 MHz (-3dB), fully loaded. This

high bandwidth allows the Matrix 50 switchers to switch everything from
NTSC video to HDTV.

Operational flexibility — Operations such as input/output selection, setting of

presets, and adjustment of audio levels can be performed on the front panel
or over the RS-232/RS-422 link. The RS-232/RS-422 link allows remote
control via a PC or control system.

• QuickSwitch Front Panel Controller (QS-FPC™) — The Matrix 50 QS-FPC

feature supports touch-of-a-button input and output selection, preset creation
and selection, and audio gain and attenuation control.

• Windows-based control program — Extron’s Windows-based control

program provides a versatile range of operational options with its graphical
interface and drag-and-drop/point-and-click operation. The Windows-based

control program also has an emulation mode that lets you create a switcher
configuration file at the home office and then download it for use by the
switcher on site.

• Simple Instruction Set (SIS™) — The remote control protocol uses Extron’s
SIS for easy programming and operation.

Audio gain/attenuation — Users can set the input level of audio gain or

attenuation (-15dB to +9dB) via the RS-232/RS-422 link or from the front
panel. Individual input audio levels can be adjusted so there are no
noticeable volume differences between sources (figure 1-2).

Global memory presets — 12 global memory presets are a time-saving feature that

lets you set up and store input/output configurations in advance and then
recall those configurations when needed with a few simple steps.

Switching flexibility — Individually buffered, independent matrix switched video

outputs with audio follow and audio breakaway for models with audio.

• Any input to any or all outputs

• Quick multiple tie — Multiple inputs can be switched to multiple outputs
simultaneously. This allows all displays (outputs) to change from source to
source at the same time.

• Audio follow — Audio can be switched with the corresponding video input.
This feature allows any audio signal to be selected with any video signal
simultaneously to one or all outputs in any combination. Audio follow
switching can be done via front panel control or under RS-232/RS-422 remote
control.

• Audio breakaway — Audio can be broken away from its corresponding
video signal. Audio breakaway switching can be done via front panel control
or under RS-232/RS-422 control.

Remote control — The Matrix 50 switchers are remote controllable, using the

MKP 1000 master control keypad and any combination of MCP 1000 slave
control panels and/or MKP 1000 slave control keypads. The remote control
devices are easy to use and provide tactile buttons for quick selection. Each
MCP 1000 can be used for one-touch switching for a particular output and
selecting global presets. Each MKP 1000 dedicated to an output can be used
to select a different input for that output or to select a preset.

Matrix 50 Series Switchers • Introduction1-4

Labeling — Extron’s label software ships with every Extron matrix switcher. You

can create labels to place alongside the front panel input buttons and output
buttons, with names, alphanumeric characters, or color bitmaps for easy and
intuitive input and output selection. Alternatively, labels can be made with
any Brother® P-Touch™ or comparable labeler.

Front panel security lockout — If a Matrix 50 Switcher is installed in an open area

where operation by unauthorized personnel may be a problem, a security
lock-out feature can be implemented. When the front panel is locked, a
special button combination is required to unlock the front panel controller

Rack Mounting the Switcher

The Matrix 50 Series Switchers are housed in rack-mountable, 2U high, 19” wide
metal enclosures. The appropriate rack mount kit is included with each switcher.
Rack mount the switcher as follows:

1. Insert the switcher into the rack, align the holes in the mounting bracket with
those of the rack.

2. Secure the switcher to the rack using the supplied machine screws.

Cabling and Rear Panel Views

All connectors are on the rear panel. Figure 2-1 shows a 12x8 Matrix 50 component
video and audio switcher. Figure 2-2 shows a 12x8 Matrix 50 S-video switcher
without an audio module. Figure 2-3 shows a 12x8 Matrix 50 composite video and
audio switcher. Figure 2-4 shows a 12x8 Matrix 50 audio switcher. The 8x4, 8x8,
and 12x4 matrixes are housed in the same 2U enclosure, but have fewer input and/
or output connectors to accommodate the different matrix sizes each provides.

The component video and S-video Matrix 50 Series switchers can also switch
video lower on the video food chain by using only two or one BNC(s). If
switching a different video format, ensure that the same video planes are used
on the switcher output as on the input.

The Matrix 50 Series Switchers do not alter the video signal in any way. The
signal output by the switcher is in the same format as the input.

Audio input and output connections (audio models only)

The captive screw connector can easily be inadvertently plugged partially
into one receptacle and partially into an adjacent receptacle. This
misconnection could damage the audio output circuits. Exercise care to
ensure the captive screw connector is plugged into the desired input or
output.

Connections for balanced and unbalanced audio inputs — Each input has a

4

3.5 mm, 5-pole captive screw connector for balanced or
unbalanced stereo audio input. Connectors are included
with each Matrix 50 Series switcher, but you must supply
the audio cable. See figure 2-5 to wire a connector for the
appropriate input type and impedance level. High
impedance is generally over 800 ohms.

The audio level for each input can be individually set, via the front panel or
RS-232/422, to ensure that the level on the output does not vary from input to
input. See chapter 3, Operation, chapter 4, Programmer’s Guide, and chapter 5,
Matrix Software for details.

If desired, attach an MCP 1000 remote
control panel master unit to the
switcher’s RS-232/RS-422 connector.

You can also connect an MKP 1000 remote keypad or MCP 1000 slave unit to
the MCP 1000 master unit. Refer to the MCP 1000 Remote Control Panel User’s
Manual and the MKP 1000 User’s Manual for details.

See chapter 4, Programmer’s Guide, for definitions of the SIS commands and
chapter 5, Matrix Software for details on how to install and use the control
software.

The Matrix 50 Series Switchers are factory configured for RS-232 control. To
use the switcher under RS-422 control, an internal cable must be moved. See
appendix B for the procedure for shifting the cable.

External sync connection

When the switching between inputs, the resulting image change should be
seamless, or clean. The Matrix 50 Series switchers can use an external signal to
synchronize switching during the vertical interval. Without the external sync
locking feature, switching between inputs can result in a brief rolling (sync loss) or
a brief change in the picture size.

External Sync In connector — Connect an external sync signal to this BNC

connection for genlocking the video signal in broadcast or other sync-critical
applications.

External Sync Out connector — Connect any downstream equipment that
requires genlocking to this BNC connector to route the external sync signal
throughout the system in broadcast or other sync-critical applications.

Figure 2-8 shows a basic external sync configuration. The Ext Sync In connector
receives a timing signal. The Ext Sync Out connector allows the signal to be passed
on to another video device, if required.

Figure 2-9 shows a configuration in which the timing source passes through three
video cameras and a video scan converter before connecting to the switcher. This
type of video camera is capable of synchronizing with the external timing source
for video editing applications.

If no external sync timing source is connected to the switcher, switching occurs
immediately.

Tie — An input-to-output connection.
Set of ties — An input tied to two or more outputs. (An output can never

be tied to more than one input.)
Configuration — May consist of one tie or one or more sets of ties.
Current configuration — The configuration that is currently being used

(also called configuration 0).
Global memory preset — A configuration that has been stored. Up to

twelve global memory presets can be stored in memory. The input buttons
select the desired preset memory location to load or retrieve a preset.
When a preset is retrieved from memory, it becomes the current
configuration. One preset can be assigned to each input button.

Input buttons, output buttons, and LEDs

If the switcher has fewer inputs and outputs than input and output buttons
and LEDs, only the applicable buttons and LEDs perform the function of
selecting and identifying an input or output.

Input 1 through 12 buttons and LEDs — The input buttons have two

1

independent functions: to select an input and to select a preset. The input
LEDs identify selected inputs. A more detailed explanation of the two
functions is included in Front Panel Operations beginning on page 3-4.

Output 1 through 8 buttons and LEDs — The output buttons and LEDs

2

select and identify outputs. On audio models the output LEDs also display
the user-adjustable audio level of the selected input. A more detailed
explanation of the two functions is included in Front Panel Operations
beginning on page 3-4.

Control buttons and LEDs

Enter button — The Enter button saves changes when you set up a new

3

configuration. To create a simple configuration, specify video, audio, or both
[see I/O selection buttons (
press the desired output buttons (

Matrix 50 Series Switchers • Operation3-2

7

) and (8)], press the desired input button (1),

2

), and press the Enter button.

Preset button and LED — The Preset button saves a configuration as a

4

preset, or recalls and makes active a previously-defined preset. The Preset
LED indicates save mode when it is blinking and recall mode when it lights
steadily.

View button and LED — The View button selects a view-only mode that

5

allows the display of the current configurations and provides a way to
mute and unmute video and audio outputs. The view-only mode helps
prevent changing configurations by accident. The View LED indicates that
the switcher is in view-only mode.

In view-only mode, pressing any input button (

1

) or output (2) button
lights the LEDs for the input and all outputs that are a part of that set of
ties. Pressing the button for any unassigned output lights only the LEDs for
all of the unassigned outputs. No input LED is lit.

As a secondary function on audio models, the View button decrements the
audio level of the selected input. In audio adjustment mode, the View LED
indicates a negative (-) attenuation value. A more detailed explanation of
audio level adjustment is included in Viewing and adjusting the audio level on
page 3-13.

Esc button and LED — The Esc button cancels operations or selections in

6

progress and resets the front panel LEDs. The Esc button does not reset the
current configuration, the Video and Audio LEDs, any presets, or any audio
gain/attenuation settings. The Esc LED flashes once after the Esc button is
pressed and released to indicate the escape function.

As a secondary function on audio models, the Esc button increments the
audio level of the selected input. In audio adjustment mode, the Esc LED
indicates a positive (+) gain value. A more detailed explanation of audio level
adjustment is included in Viewing and adjusting the audio level on page 3-13.

I/O controls

When creating or viewing a configuration, you must specify whether the
configuration applies to video, audio, or both. This is done with the Video (
and Audio (

7

8

7

)

8

) buttons.

Although present, the Audio button has no function on video only models.

Video button and LED — The Video button selects and deselects video for a
configuration that is being created or viewed. The Video LED lights to
indicate that video is available for configuring or for viewing.

Audio button and LED — The Audio button selects and deselects audio for a
configuration that is being created or viewed. The Audio LED lights to
indicate that the audio configuration follows the video configuration. The
Audio LED blinks to indicate that the audio configuration is broken away
from the video configuration.

As a secondary function, the Audio button selects the audio level display/
adjustment mode. Press and hold the Audio button until the Audio LED
begins to blink. If the Video LED was lit, it turns off. Select an input. The
current audio level setting for the selected input is displayed by the output
LEDs. The audio level for the selected input can be increased and decreased
by pressing the View (

5

) and Esc (6) buttons. A more detailed explanation
of audio level adjustment is included in Viewing and adjusting the audio level
on page 3-13.
