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:

R1 ‡ output (1~2) ‡ up arrow

Deactivate Video & Audio Mute: R1 ‡ output (1~2) ‡ down arrow

Volume Control

Left and right analog stereo audio volume control feature provided for YPbPr mode (RGBHV video mode does not support analog audio due to connector limitations).

FAT BOY SERIES EXPANSION

The KD-MSW4x2Pro is available as a stand-alone base unit, or pre-wired from Key Digital™ as multiple Fat Boy units from the factory in an expanded output conﬁguration. The KD-MSW4x2Pro is available pre-wired from the factory in output expansion conﬁgurations that increment in steps of two (at the output).

Operation of a base KD-MSW4x2Pro (conﬁgured as a 4x2 matrix switcher) is described in detail in this Operating Manual.

IR Remote Sensor

Use this front-panel pushbutton to select any of the up to four source input devices to drive the display and audio system wired to Output 1. Press the button and cycle through Input 1, 2, 3, and 4.

Repeat for Output 2 using the appropriate Output 2 pushbutton and LEDs for monitoring the input selection.

Input 1, 2, 3, and 4 LED indicators

Note:

Since the KD-MSW4x2Pro 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-MSW4x2Pro by Key Digital™, a state-of-the-art analog HDTV Fat Boy Series 4-Input to 2-Output matrix switcher and distribution ampliﬁer.

A base KD-MSW4x2Pro unit has 4 inputs to 2 outputs. 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 HDTV 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.

The KD-MSW4x2Pro is available pre-wired from the factory in output expansion conﬁgurations that increment in steps of two (at the output).

The KD-MSW4x2Pro 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-MSW4x2Pro 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-MSW4x2Pro 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-MSW4x2Pro uses BNC connectors 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-MSW4x2Pro 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-MSW4x2Pro 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-MSW4x2Pro 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-MSW4x2Pro provides the user with two degrees of freedom:

The ability to select any particular input source device, namely the source devices connected to Input 1, 2, 3, or 4

These input devices can be chosen separately for Output 1 and Output 2 Available as pre-wired output expansions: (4x2 base), 4x4, 4x6, and 4x8

Distribution Ampliﬁer Application

If desired, the unit also acts as a distribution ampliﬁer, simultaneously routing any single input to both outputs.
