Typical Application Example for the KD-MSW4x2 HDTV Matrix Switcher
Detailed Input/Output Descriptions
The interconnection of video and audio equipment in the various formats supported by the KD-
MSW4x2 unit is described here in detail. This section is particularly useful if some source devices
or displays are only available with S-Video or Component Video formats
High-quality Component Video (YPbPr) and “VGA” (RGBHV) Source Equipment
Some source equipment may have an analog video output that is called Component Video, a
3-wire video format with the video signals labeled YPbPr. Another common analog video output
format is RGB (like the “VGA” outputs on a computer), which typically has separate H&V sync
signals. The KD-MSW4x2 HDTV Matrix Switcher is the perfect choice for switching Component
Video and RGBHV Video source devices to displays with analog inputs.
Example: Connecting a digital TV set-top receiver with Component Video three-wire YPbPr or
“VGA” five-wire RGBHV video Outputs to the KD-MSW4x2 HDTV Matrix Switcher Inputs
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 four Input Ports on the rear of the
KD-MSW4x2 unit. Connect the white and red analog stereo audio cables from the set-top receiver
to the white and red connectors of the same Input Port of the KD-MSW4x2 unit. If a digital audio
coaxial output is available on the set-top receiver, it can then connect to the black-coded PCM
connector on the KD-MSW4x2 unit.
Connect the green, blue, and red connectors from Output Ports 1 or 2 on the KD-MSW4x2 unit
to the corresponding component video jacks on the desired display. Connect the white and red
analog audio jacks from the same Output Port to the corresponding white and red audio jacks on
the audio system (which may be built into the display). If digital PCM audio is desired from the set-
top receiver, connect a cable from the black connector in the same chosen Output Port to the A/V
receiver's coaxial digital audio input.

For proper operation of the high quality electrical circuits in the KD-MSW4x2 unit,
do NOT “daisy chain” inputs:
Each input of the KD-MSW4x2 has its own 75 Ω termination
Do NOT feed a source to multiple KD-MSW4x2 inputs without proper
distribution equipment

CAUTION: To prevent damage to equipment, do NOT connect the KD-MSW4x2
digital PCM audio outputs to any analog audio inputs on a display or audio system!
