KD-MSW8x4Pro Operating Instructions
GETTING STARTED
The KD-MSW8x4Pro HDTV Matrix Switcher is capable of switching eight (8) sets of three-wire
component (YPbPr) video and/or five-wire component (RGBHV) video, as well as analog/digital
audio to any or all of the four outputs (typically your displays or projectors). If your source
device has a VGA output connector, you will need a VGA-to-BNC breakout cable. The KD-
MSW8x4Pro HDTV Matrix Switcher is also capable of switching S-Video and composite video
signals (with the appropriate cable adapter) from VCR's, digital video recorders and satellite set-
top receivers. The default video signal format for the KD-MSW8x4Pro HDTV Matrix Switcher is
three-wire Component Video (YPbPr).
Note: Since the KD-MSW8x4Pro Matrix Switcher does NOT perform video processing,
the output video format is the same as the input video format. This means that
the video resolution is not changed and also that if you input one form of video,
for example Component Video, the output will be in exactly the same format.
Open the carton and you will find the following contents:
1. One KD-MSW8x4Pro HDTV Matrix Switcher unit1
2. One +6V DC external Power Supply adapter module2
3. IR Remote Control with batteries included

KD-MSW8x4Pro Operating Instructions
Setting up your KD-MSW8x4Pro HDTV Matrix Switcher for operation:
Your KD-MSW8x4Pro HDTV Matrix Switcher is easy to configure and operate. In this section,
you will first connect all of your A/V Input and Output devices to your KD-MSW8x4Pro Matrix
Switcher unit.
Connecting A/V Equipment
Connecting A/V equipment to the KD-MSW8x4Pro HDTV Matrix Switcher is straightforward and
accomplished easily via the ergonomic rear panel connector array.
CAUTION: When unpacking the unit, make all hookups and connections
before plugging in the Power Adapter provided with your unit. Do NOT
apply power to the unit until all Video and Audio connections have been
made to your KD-MSW8x4Pro unit(s) from the “Source” devices to the
Display(s) and/or Audio system(s). You MUST use the Power Supply
provided with your unit or you VOID the Key Digital Warranty and risk
damage to your unit and associated equipment.
The KD-MSW8x4Pro HDTV Matrix Switcher is equipped with professional-grade BNC female
connectors. These connectors offer a better match to video cables than do the smaller RCA
connectors, as well as providing a positive bayonet lock when installed. Because not all con-
sumer equipment marketed uses BNC connector interfaces, it may be necessary to employ
RCA-to-BNC or VGA-to-BNC adapter plugs and/or cable assemblies to interface these various
devices to your high-quality Matrix Switcher.
The video signal format must be considered when making connections to the KD-MSW8x4Pro
HDTV Matrix Switcher. Simply match the A/V device’s output (be it YPbPr “Component” or
RGBHV “VGA” video) to a similar video signal output configuration on the KD-MSW8x4Pro
HDTV Matrix Switcher. In the event that these superior quality output formats are not available
on the device in question, then S-Video and/or composite video may also be interfaced with
the KD-MSW8x4Pro HDTV Matrix Switcher with the use of the appropriate adapters.
The same consideration applies to the audio interfaces. Both analog and digital output options
are provided on the KD-MSW8x4Pro HDTV Matrix Switcher and may be employed appropriate-
ly as analog, when connecting directly to the audio inputs of a video monitor; or as digital,
when connecting instead to an A/V receiver having coaxial digital (PCM) interfaces for decoding
surround sound signals.

Rear panel layout of the KD-MSW8x4Pro Matrix Switcher
CAUTION: Connecting digital audio signals directly
to the analog audio input of a TV monitor or other
display can result in severe damage to its speakers.
The color-coded rear-panel layout illustrates the eight
Inputs and four outputs of the KD-MSW8x4Pro HDTV Matrix
Switcher, as well as the RS-232 control interface.
Note: The Left and Right audio interfaces also double as the
Horizontal and vertical Sync signals, respectively, for the RGB
Video interface.
High-quality Component Video (YPbPr) and “VGA” (RGBHV)
Source Equipment
Some of your source equipment may have an analog video output that is called Component
Video. Component Video is a three-wire video format, with the video signals typically labeled
YPbPr. Another common analog video output format is RGB (like the “VGA” outputs on your
computer), which typically has separate H&V sync signals. The KD-MSW8x4Pro HDTV Matrix
Switcher is the perfect choice for switching Component Video and RGB Video source devices
to your displays.
Example: Connecting a digital TV set-top receiver with Component Video three-wire
YPbPr or “VGA” five-wire RGBHV video Outputs to the KD-MSW8x4Pro HDTV Matrix
Switcher Inputs.
Model #: KD-MSW8x4Pro
YPbPr Component Video
Connect the three-wire green, blue and red YPbPr cables from the set-top receiver of choice,
to the green, blue and red color-coded connectors of any one of the eight input fields of the
KD-MSW8x4Pro HDTV Matrix Switcher. Connect the white and red analog stereo audio cables
from the set-top receiver to the white and orange connectors of the same input field of the KD-
MSW8x4Pro HDTV Matrix Switcher. If a digital audio coaxial output is available on the set-top
receiver, it can then connect to the gray-coded PCM connector on the KD-MSW8x4Pro HDTV
Matrix Switcher.
Connect the green, blue and red connectors from Outputs 1, 2, 3 or 4 on the KD-MSW8x4Pro
HDTV Matrix Switcher to the corresponding component video jacks on your TV or monitor.
Connect the white and orange analog audio jacks from the same output to the corresponding
white and red audio jacks on your TV or monitor. If digital audio is desired from the set-top
receiver, connect a cable from the gray BNC connector in the same chosen output field to your
A/V receiver’s coaxial digital audio input.
CAUTION: To prevent damage to your equipment, do NOT connect the
KD-MSW8x4Pro HDTV Matrix Switcher digital outputs to either of the
analog audio inputs on your TV or monitor!
RGBHV
If the set-top receiver of choice employs RGBHV outputs, a 15-pin ‘breakout’ adapter cable will
need to be used to implement the interface. In this instance connect the red, green and blue
BNC connectors from this adapter cable to the red, green and blue connectors, again on any
one of the eight input fields, of the KD-MSW8x4Pro HDTV Matrix Switcher. Connect the black
and yellow wires from the breakout cable to the white and orange (analog audio input) connec-
tors in the same input field of the KD-MSW8x4Pro HDTV Matrix Switcher.
Now connect the desired RGBHV video signal to your monitor or TV, by connecting the red,
green, blue, white, and orange connectors of any one of the four output fields of the KD-
MSW8x4Pro HDTV Matrix Switcher, directly to the red, green, blue, black, and yellow input
connectors on your monitor or TV. These connectors may also be labeled R, G, B, H, and V. A
second 15-pin breakout cable may be required for certain sets.
Note: It is not possible to use analog audio switching when in RGB mode, because the H&V
sync signals required for the RGB format will occupy the port connectors typically used for the
audio signals. This leaves the option, if desired, of connecting digital audio (PCM) from the set-
top receiver to same input and output fields of the KD-MSW8x4Pro HDTV Matrix Switcher.
This same connection procedure described above applies to any other peripheral
device that one may wish to interface with a desired display medium, including DVD players
and game consoles.

Lower-quality S-Video (two-wire) or Composite Video (CVBS)
Source Equipment
S-Video
A “breakout” adapter cable is required to connect a satellite receiver, DVR, or S-VHS VCR to the
KD-MSW8x4Pro HDTV Matrix Switcher. This cable is equipped with an S-Video (DIN) plug at
one end and a pair of BNC plugs at the other connected to white and yellow conductors.
Connect the white (Y) conductor to the green BNC connector in the selected input field, and
connect the yellow (C) conductor to either the blue or red BNC connector in the same input
field. Connect the white and red analog stereo audio connectors of the set-top receiver of
choice, to the white and orange connectors in the same input field on the KD-MSW8x4Pro
HDTV Matrix Switcher.
Connect the green BNC connector in the selected output field to the white (Y) conductor of a
second S-video to BNC adapter cable. Connect the blue or red connector to the yellow (C)
conductor. Plug the other end of the adapter cable into the TV or monitor’s S-video input.
Connect the white and red analog stereo audio cable connectors to the white and orange con-
nectors of the same KD-MSW8x4Pro HDTV Matrix Switcher output field. Connect the other
end of the audio cable pair to the white and red analog audio input of your TV or monitor.
Composite Video (CVBS) Connection
Connect the Composite Video connector (yellow) from your VCR or DVR to the green BNC
connector in the selected KD-MSW8x4Pro HDTV Matrix Switcher input field. Connect another
composite video cable from the green BNC connector in the selected output field to your TV or
video monitor. Follow the instructions above for connecting analog audio.
Applying power to your unit
CAUTION: No other power supply adapter can be used with the
KD-MSW8x4Pro unit(s); you must use the Power Supply provided!
Using a power supply other than the one provided by Key Digital

BASIC OPERATION
A “Matrix Switcher” allows you to select any input device, and have it available on the output
(typically a display) of your selection. For example, not only can you select your DVD player as
the source of video for your enjoyment from your total array of source devices like Set Top
Boxes and DVR’s, but you can also direct the DVD player to appear on your HDTV or any par-
ticular display you have connected to the output of your Matrix Switcher, while you monitor
other sources on other displays under your command.
All input/output combinations are configurable via the front panel pushbuttons and clearly dis-
played by LED indicators for each of the output fields. Switching can be accomplished conve-
niently in any of three ways:
■
Manually, using the front panel pushbuttons and LED indicators
■
Remotely, using the supplied IR remote control
■
Using the RS-232 control
Manual configuration of A/V Inputs and Outputs
Manual routing of video and audio signals from the available inputs to selected outputs is easily
implemented on the KD-MSW8x4Pro HDTV Matrix Switcher using the front panel pushbuttons,
and visually verifiable via the LED indicator array for each of the four output fields.
The front panel of the KD-MSW8x4Pro HDTV Matrix Switcher provides the user with a visual
representation of the four output fields. Each of these four segments consists of a large push-
button and an array of eight LED indicators. Each of these appropriately numbered LED indica-
tors corresponds to one of the eight available inputs.
Once the input source devices and the output displays have been connected to the KD-
MSW8x4Pro HDTV Matrix Switcher they can easily be configured into desired combinations
using these simple pushbuttons.
To switch an A/V device input to the intended one of the four outputs requires depressing the
pushbutton corresponding to the chosen output field, as necessary, until the LED indicator
corresponding to the chosen input is lit. The video and audio sources connected to that input
are automatically switched to the selected output. The KD-MSW8x4Pro HDTV Matrix Switcher
can simultaneously route a single input to all of the four outputs by simply repeating the same
procedure for each of the four output fields.

Fade-to-Black and Video Mute pro-features
Two new features have been added to this generation of Key Digital®switchers, called “Fade-to-
Black” and “Video Mute.” Both of these features let you switch like a pro, like in a live studio.
The Fade-to-Black feature allows for switching between input/output combinations without
the usual visual signal noise that traditionally accompanies switching between video signals.
The video image momentarily goes to black as the KD-MSW8x4Pro HDTV Matrix Switcher
selects between inputs for the chosen output.
An additional related feature, available on the KD-MSW8x4Pro HDTV Switcher, is the Video
Mute, which enables the user to mute the video signal (the display goes to black) at the chosen
output.
IR REMOTE CONTROL
The KD-MSW8x4Pro HDTV Matrix Switcher can be operated remotely using the supplied
infrared (IR) remote control. As many as fifteen individual KD-MSW8x4Pro HDTV Switchers can
be addressed by the same remote control using the few simple functions designed into the system.

KD-MSW8x4Pro Operating Instructions
Selecting input and output combinations with the IR Remote
Configuring a particular unit (the Fat Boy series allows multiple units of the KD-MSW8x4Pro
base unit operate together for installations requiring more than 4 displays*) with the desired
input and output combination requires the following successive steps:
1. Addressing desired Unit:
Depress numerical digits 01 to 15 (16 is the default address of the stand alone / base
unit and does not require selection)
2. Addressing desired Output:
Depress Output 1 to 4 keys
3. Addressing desired Input:
Depress numerical digits 1 to 8
*Note: The KD-MSW8x4Pro HDTV Switcher is massively expandable in increments of four (4)
Outputs by purchasing multiple units from Key Digital®that have been pre-wired and configured
with a special cable kit. For example, by combining as many as 11 base 8x4 units together,
offers the KD-MSW8x4Pro-8x44 HDTV Matrix Switcher package that provides 8x44 Matrix
Switching (that is, any of 8 inputs to up to as many as any of 44 outputs). For such applica-
tions, each unit must be addressed separately unless the system is under RS-232 control.
Volume Control
An analog audio volume control feature for the left and right analog stereo audio is provided for
the YPbPr mode (RGBHV video mode supports only digital PCM audio without the volume
control).
The IR remote control provided with the KD-MSW8x4Pro has four volume control buttons:
Output 1, Output 2, Output 3 and Output 4 volume selection
Listed below are the remote control functions that support audio volume control for Output 1.
The same IR functions apply to control the Output 2, 3 and 4 volume control.
Adjust Output 1 L&R analog audio volume:
■
Increase the volume: press IR Output 1 volume selection button –> UP arrow button
■
Decrease the volume: press IR Output 1 volume selection button –> DOWN arrow button
Default:
To set Output 1~4 volume back to default (0 dB):
press Output 1~4 volume selection button –> U3 button
Mute:
■
Mutes Output 1~4 analog audio: press Output 1~4 volume selection button –> U1 button
■
Turn off audio mute: press Output 1~4 volume selection button –> U2 button

Enabling and disabling Lockout functionality is accomplished via "R3" key:
Press and hold "R3" once to enable, press and hold "R3" again to disable.
Flashing front panel LEDs indicate that the command has been accepted.
Example of use when IR Remote Lockout is enabled:
1. Depress and release R2 key
2. Set any I/O combination as described in “Setting input and output combinations”
in this section
Example of use when IR Remote Lockout is disabled:
1. Simply set any I/O combination as described in “Setting input and output combinations”
in this section
IR Timing
The minimum timing interval between IR commands is 0.5 seconds.
Note: Exception is input switching commands. For input switching commands the minimum
timing interval between successive IR commands is determined by the Fade-to-Black period
set via RS-232.
The minimum period here is the greater of the two: 0.5 sec or Fade-to-Black interval.
Please see Fade-to-Back Interval Set command in the RS-232 protocol section of this manual
for more information.

Fat Boy Expansion: Theory of Operation
The Fat Boy KD-MSW8x4Pro HDTV Matrix Switcher series is expandable to as many as 44
configurable outputs, allowing for even greater input/output flexibility for the given eight input
arrays. This expansion feature is factory installed and shipped to the consumer as a pre-wired
and pre-tested combination of from two up to eleven KD-MSW8x4Pro HDTV Matrix Switchers.
The expansion packages are comprised of multiple KD-MSW8x4Pro units ganged together.
In the expansion configurations, the individual connectors of each input array, on each unit, are
connected to all other corresponding input array connectors on all of the other units (up to
eleven units for the massive KD-MSW8x4Pro – 8x44 HDTV Matrix Switcher configuration) of a
given expanded package. Each of the eight combined input fields is then supplied with a sin-
gle input array (R, G, B, PCM Audio, Left Audio and Right Audio). The resulting output arrays
(eight, or twelve, or sixteen, … up to 44), depending on the expansion package chosen, are
configurable in the same way as those of a single switcher. The stand-alone or combined
package KD-MSW8x4Pro HDTV Matrix Switcher is addressable in the same manner as
described prior, using either the supplied IR Remote Controller or via the RS-232 control port.
Using the same application example illustrated previously, the user will note that the input video
and audio sources remain the same. The signals for each of the inputs shown are supplied to
each of the additional units of a given expanded package via the parallel connection array
described earlier. The output array available (up to 44 with 11 base KD-MSW8x4Pro units) now
offers you additional interfaces for display devices and/or surround sound systems.
CAUTION: Do not tamper with
factory installed wiring as this
may lead to improper functioning
of equipment and conceivably
cause damage to the same.
The combined units provide the user with a virtually
unlimited output capability (up to 44). As illustrated previ-
ously in this manual, up to eight individual inputs are
available for an array of source devices, ranging from
VCR’s to DVD players and HDTV Set Top boxes.
The following Expansion Application Example is that of
an expanded KD-MSW8x4Pro HDTV Matrix Switcher
Package (8x16). The four 8x4 interconnected switcher
units provide, for the eight segment input field (shown in
gray), additional interfacing with an expanded array of
sixteen (16) individual outputs (shown in red). The nec-
essary wiring is factory installed and the expanded
switcher package shipped to the consumer ready for
connection to the video and audio equipment of choice.
