The Fat Boy Series KD-MSW4x2 by Key Digital™‚ is an analog HDTV 4-Input to 2-Output matrix switcher and distribution amplifier. For each of the two displays connected to its output, any of up to four source inputs can be separately and seamlessly switched with the professional Fade-to-Black and Video Muting features. It supports both component video (YPbPr) and RGBHV video formats; and S-Video and composite video (CVBS), with adapters. Concurrent with the video, it switches and distributes PCM coax digital audio, and analog stereo audio (no analog audio for RGBHV video). With analog video bandwidths up to 300 MHz, the KD-MSW4x2 handles all HD and SD resolutions (50 and 60 Hz) including 1080p/60, with no degradation in signal quality. It is simple to operate and control via front panel pushbuttons with LEDs to monitor the selections, IR remote control, IR Extender, wired IR, and is compatible via RS-232 with all control systems.

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.
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).

Additional Product Features
Several new features have been added to this generation of Key Digital™ switchers, called “Fade-to­Black” and “Video Mute.” Both of these features let the user switch like a pro, like in a live studio.
Fade-to-Black
The Fade-to-Black feature allows for switching between input/output combinations without the usual visual signal noise, glitches, and sync roll that traditionally accompany switching between video signals. The feature momentarily forces the video image to black as the desired source input is selected for the chosen output. This feature is applied automatically and the fade time
interval is programmable via RS-232.
Video and Audio Mute
Video and Audio Mute enables the user to mute the audio and video signal (the display goes to black) at the chosen output, using the RS-232 [see the RS-232 Command List] or IR remote control. Using the IR remote control for Video and Audio Muting:
Activate Video & Audio Mute: Deactivate Video & Audio Mute: R1 ‡ output (1~2) ‡ down arrow
R1 ‡ output (1~2) ‡ up arrow
Note: Since the KD-MSW4x2 Matrix Switcher does NOT perform video processing, the output video format is the same as the input video format. This means that the video resolution is not changed and also that form of video is input to the unit, for example Component Video, the output will be in exactly the same format.

Introduction
Thank you for purchasing the KD-MSW4x2 by Key Digital™, a state-of-the-art analog HDTV Fat Boy Series 4-Input to 2-Output matrix switcher and distribution amplifier.
Each of its two distinct outputs can be used to drive two separate displays (and audio / surround sound systems), even the most exotic high-end HDT V projectors on the market. One of up to four source input devices (like DVD players, Set Top Boxes, etc.) can be independently and separately selected to drive each display. Switch like a pro in the Studio, with the all-new “Fade-to-Black” and “Video Muting” features that eliminate video “glitches” on the display when switching different inputs. If desired, the unit functions as a distribution amplifier, simultaneously routing any single input to both outputs. Also, the product is expandable.
The KD-MSW4x2 uses RCA jacks for video and audio inputs and outputs, and supports both component video (YPbPr) and RGBHV video formats. Along with the video, it concurrently switches and distributes digital PCM, and analog stereo audio for YPbPr operation only.
The KD-MSW4x2 is simple to operate and control via front panel pushbuttons and LEDs, IR (Infrared) remote control, IR Extender, wired IR, and is compatible via RS-232 with all control systems.
The KD-MSW4x2 is perfectly suited for studio, home theater, custom installation, retail, and in fact any and all analog HD and SD applications. With analog video bandwidths up to 300 MHz, it handles all HD and SD resolutions (50 and 60 Hz) including 1080p/60, with no degradation in video or audio signal quality. Since the KD-MSW4x2 performs no video or audio processing, the video and audio signals remain pure and untouched, and hence the quality of the output signals is the same as the quality of the input signals.
Typical source input devices that can be matrix switched with the KD-MSW4x2 include:
DVD players
›
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 boasts a 300 MHz analog video bandwidth due in part to the following custom and proprietary Key Digital™ technologies engineered into the product to ensure the highest standard of picture quality:

Matrix Switching
The KD-MSW4x2 is a Matrix Switcher that accepts up to four inputs from source devices, and can drive up to two displays.
A “Matrix Switcher” allows the user to select any input source device, and have it available on any desired output (typically a display). For example, the user may choose to view a DVD player on the display that is connected to Output 1, and view the satellite box on the display that is connected to Output 2. A true matrix switcher, the KD-MSW4x2 provides the user with two degrees of freedom:
