R/V Connector (Right analog stereo audio, or vertical sync for RGBHV video)

R label is for the right analog stereo audio channel
V label is for the vertical sync for RGBHV video

PCM Connector:

For PCM digital coax audio

Control Connections

Decide how the KD-MSW4x2Pro will be controlled
If using an IR (Infrared) Extender, the wired IR, or an external Control System (via the RS-232 port 

on the KD-MSW4x2Pro), make the appropriate connections

Power

Use ONLY the external power supply provided with the KD-

MSW4x2Pro unit.  Use of any other power supply VOIDS the 

Key Digital

 Warranty and may potentially damage the unit and 

any associated equipment.
Connect the external power supply provided with the  

KD-MSW4x2Pro to the jack on the rear panel of the unit.  
Connect the power supply to an appropriate source of power, such as from a wall outlet.

operation

Follow all manufacturer instructions for the safe and proper operation of the source and display 

products that have been connected to the KD-MSW4x2Pro.
Using one of the convenient control options for the KD-MSW4x2Pro, separately select source 

input 1, 2, 3, or 4 for output display 1, and source input 1, 2, 3, or 4 for output display 2.
Use the IR remote control with an extensive command and control capability.   

See the description for the IR remote control provided later in this Operating Manual.
It is also possible under RS-232 control to allow any one of the four inputs to be switched and 

distributed to both outputs [see the RS-232 Command List].

Additional Product Features

Several new features have been added to this generation of Key Digital

 switchers, called “Fade-to-

Black” 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.

CAuTIon:  If purchased as a Fat Boy expansion of the base 4x2 
matrix switcher configuration, the multiple base units will come 
pre-connected and tested from the factory.  It is advised noT to 
disconnect or reconfigure any of these cables.

These Operating Instructions apply to the entire Key Digital
