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-MSW8x4 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-
MSW8x4 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-MSW8x4 HDTV
Matrix Switcher.
Connect the green, blue and red connectors from Outputs 1, 2, 3 or 4 on the KD-MSW8x4
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-MSW8x4 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-MSW8x4 HDTV Matrix Switcher. Connect the black and
yellow wires from the breakout cable to the white and orange (analog audio input) connectors
in the same input field of the KD-MSW8x4 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-
MSW8x4 HDTV Matrix Switcher, directly to the red, green, blue, black, and yellow input connec-
tors 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-MSW8x4 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.
KDMSW8x4 Operating Instructions
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-MSW8x4 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-MSW8x4 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-MSW8x4 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-MSW8x4 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-
MSW8x4 unit(s); you must use the Power Supply provided! Using a
power supply other than the one provided by Key Digital with your unit
VOIDS THE WARRANTY, may cause damage to your unit and associated
equipment, and is a potential safety hazard.
Now that the installation is completed, it is recommended to double check all connections
before connecting the external power supply. Once every connection has been verified, plug
the connector of the Power Supply into the power input jack of the KD-MSW8x4.
