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.
