Connecting the Video and Audio Inputs and Outputs
Decide on a safe location to place or mount the KD-MSW4x2. Provide enough space for sufficient
airflow and ventilation, especially if the unit is left “On” most of the time.
Connecting A/V Equipment
Connecting A/V equipment to the KD-MSW4x2 HDTV Matrix Switcher is straightforward and easily
accomplished via the ergonomic rear panel connector array. Because not all consumer equipment
marketed today uses RCA connector interfaces, it may be necessary to employ adapter plugs
and/or cable assemblies to interface these various devices to the unit.
The video signal format must be considered when making connections to the KD-MSW4x2 unit.
Simply match the A/V device’s output (namely YPbPr “Component” or RGBHV “VGA” video) to a
similar video signal output configuration on the KD-MSW4x2. S-Video and/or composite video
may also be interfaced with the unit, using appropriate adapters available separately.
The same consideration applies to the audio interfaces. Both analog and digital audio output
options are provided on the KD-MSW4x2. Use the appropriate format, such as analog audio when
connecting directly to the audio inputs of a video monitor; or digital audio, when connecting instead
to an A/V receiver having coaxial digital (PCM) interfaces for decoding surround sound signals.
Do not connect the external supply (provided) to the back
of the KD-MSW4x2 unit until ALL of your video and audio
connections are completed.
Test for proper operation of the unit, interconnections, and cables before final
installation of cables behind walls or ceilings. The output stage of the KD-MSW4x2
is capable of driving high-quality, equal-length video cables up to 300’ or more.
CAUTION: 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 feel a source to multiple KD-MSW4x2 inputs without
proper distribution equipment

CAUTION: The output stage of the KD-MSW4x2 can drive high-quality
length video cables up to 300' or more. Be sure to use high-quality
cables like those available through Key Digital
™ . Always ensure cables
for each output are equal in length for each video component.
CAUTION: Connecting digital PCM audio signals directly to the analog
audio input of a TV monitor, display, or other device can result in
severe damage to its speakers.
The 4 Input Ports and the 2 Output Ports are Configured Identically
The Port configurations are the same for the 4 Input Ports and the 2 Output Ports. Each Port is
comprised of six (6) color-coded RCA connectors:
Connect up to four video and audio sources to the RCA jack Input Ports of the KD-MSW4x2.
Digital PCM audio is available with either YPbPr or RGBHV video
Analog stereo audio is available with YPbPr video but not RGBHV video, unless the sync is on
green (G)
Connect up to two displays to the RCA jack Output Ports of the KD-MSW4x2. The audio
outputs from the product can be connected to the audio inputs of the display, or separate
surround sound or other audio systems.
