KD-MSW4x2 Operating Instructions

The KD-MSW4x2 by Key Digital‚ is an analog HDTV Fat Boy Series 4-Input to 2-Output matrix switcher and distribution amplifier. It is perfectly suited for studio, home theater, custom installation, retail, and in fact any and all analog HD and SD applications.

Typical Configuration: Analog HDTV

›Connect four sources to the input of the KD-MSW4x2 (for example: a DVD player, Cable Set Top Box, Satellite Set Top Box, and PC)

›Connect two displays to the output of the KD-MSW4x2 (for example, a Plasma and an LCD display)

›Connect the audio outputs of the KD-MSW4x2 to surround sound or other audio systems, or to the speakers in the displays

›It is expandable

Matrix Switcher and Distribution Amplifier

›For each of the two KD-MSW4x2 outputs that can be used to drive separate displays, one of the four source inputs can be independently selected

›For example, it’s as easy as 1, 2, 3:

1.Connect the video and audio from a DVD player, Cable Set Top Box, Satellite Set Top Box, and PC to the inputs of the KD-MSW4x2

2.Connect the video (and audio) outputs of the KD-MSW4x2 to two displays, a Plasma and an LCD (the audio may be separately connected to surround sound or other audio systems, or to the speakers in the displays)

3.Use any of the control options on the KD-MSW4x2 to select the Cable Box to drive the Plasma and the DVD player to drive the LCD, or any other combination

›It is also possible under RS-232 control to allow any one of the four inputs to be switched and distributed to both outputs.

Professional Switching Features

›Fade-to-Black: 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

➔Fade time interval is programmable via the RS-232 [see the RS-232 Command List], and is equivalent to a “Video Mute” to force the video to black during switching

›Video Mute: enables the user to mute the video signal (the display goes to black) at the chosen output
