KD-MSW4x2 Operating Instructions

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

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

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.

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!
