KD-MSW4x2 Operating Instructions

Quick Setup Guide

If the user or installer is familiar with Video/Audio Matrix Switching and Distribution, then the following Quick Setup Guide can be used as a shortcut. It is recommended to always follow all the detailed instructions provided in this entire Operating Manual to properly hook-up, operate, and control the KD-MSW4x2 product.

Basics Facts About the KD-MSW4x2

The KD-MSW4x2 is a 4-Input to 2-Output video and audio matrix switcher and distribution amplifier. Each of its two distinct outputs can be used to drive two separate displays and audio/ surround sound systems. One of up to four source input devices can be independently and separately selected to drive each of the two displays and audio systems. The product provides professional-grade switching, with the Fade-to-Black and Video Mute features, preventing image glitches when switching between sources.

Typical source input devices that can be matrix switched with the KD-MSW4x2 include:

›DVD players and changers

›Cable TV, satellite, and terrestrial Set Top Boxes (STBs)

›Digital Video Recorders (DVRs)

›D-VHS, S-VHS and VHS VCR’s

›Electronic game boxes

›Personal Computers (PCs)

The KD-MSW4x2 handles all HD and SD resolutions, and is compatible with all standard analog video signal formats, including:

›1080p, 1080i, 720p, 576p, 576i, 540p, 480p, 480i

›50 Hz or 60 Hz refresh rates

The KD-MSW4x2 performs no video or audio processing, and supports video bandwidths up to 300 MHz. Its output stage drives high-quality, equal-length video cables up to 300’ or more. The output formats and resolutions are identical to those at the input to the unit.

The KD-MSW4x2 uses RCA jacks for video and audio inputs and outputs, and supports both component video (YPbPr) and RGBHV video formats; as well as S-Video and composite video (CVBS), with adapters. Along with the video, it concurrently switches and distributes PCM coax digital audio, and analog stereo audio (for YPbPr operation only).

The KD-MSW4x2 has four (4) Input Ports and two (2) Output Ports. Each Input Port and Output Port is comprised of six (6) color-coded RCA jacks:

›3 analog video connectors (YPbPr or RGB, shared as Pr/R Y/G Pb/B)

›2 analog audio connectors (Left and Right stereo pairs)

›The analog audio input/output connectors also serve as the horizontal (H) and vertical (V) sync for RGBHV signals

›1 PCM digital coax audio connector
