4x2 PRO BNC Component/RGBHV A/V Matrix Switcher DA 

The Fat Boy Series KD-MSW4x2PRO 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) using robust BNC connectors. 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-MSW4x2PRO 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 push buttons with LEDs to monitor the selections, IR remote control, IR Extender, wired IR, and is compatible via RS-232 with all control systems.

 

Matrix Switching

• Supports Video and Audio
• Four (4) Source Input Ports and two (2) Zone Output Ports provided
• Matrix switch one of up to four inputs to either of two outputs
• For each of the two outputs that can be used to drive separate displays, one of the four source inputs can be independently selected
• Also acts as a distribution amplifier, simultaneously routing any individual input to both outputs Using RS-232 control
• Analog Audio Volume Control with Muting provided

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, and is equivalent to a "Video Mute" to force the video to black during switching
• See the RS-232 Command List
• Video Mute: enables the user to mute the video signal (the display goes to black) at the chosen output
• Input/Output Ports and Formats
• The output format = the format of the selected input source

Each Input and Output Port is comprised of six (6) BNC connectors :

• 3 analog video connectors
• 2 analog audio connectors
• The analog audio input/output connectors also serve as the horizontal and vertical sync for RGBHV signals
• 1 PCM digital coax audio connector

Each Port supports:

• YPbPr component video, analog stereo left and right audio, and digital PCM audio
• RGBHV video and digital PCM audio
• RGB video with sync on the green channel, analog stereo left and right audio, and digital PCM audio
• S-Video and composite video (CVBS), with adapters

Each connector can accommodate various signals, on a shared basis:

• PR/R Connector:
• Pr label is for component video
• R label is for the red channel for RGBHV video

Y/G Connector:

• Y label is for component video
• G label is for the green channel for RGBHV video
• Pb/B Connector:
• Pb label is for component video
• B label is for the blue channel for RGBHV video
• L/H Connector:
• L label is for the left analog stereo audio channel
• H label is for the horizontal sync for RGBHV video
• 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

Resolution

• The output resolution = the resolution of the selected input source
• Handles all HD and SD resolutions (50 and 60 Hz) including 1080p/60
• Supports analog video bandwidths up to 300 MHz
• Performs no video or audio processing:
• Introduces no degradation in video or audio signal quality

Compatible Video Signals

• Compatible with all standard analog video signal formats that use 50 Hz or 60 Hz refresh rates, including: 1080p, 1080i, 720p, 576p, 576i, 540p, 480p, 480i

Video Characteristics

• Output stage drives high-quality, equal-length video cables up to 300’ or more
• 1V p-p @ 75 ohms, terminated
• Composite video sync on "Y" input (YPbPr)
• Video bandwidth:
• -3 dB @ 300 MHz
• Linear phase pass-band
• Unity video gain
• Input terminations: for proper operation of the high quality electrical circuits in the KD-MSW4x2Pro unit, do NOT "daisy chain" inputs:
• Each input of the KD-MSW4x2Pro has its own 75 ohm termination
• Do NOT feed a source to multiple KD-MSW4x2Pro inputs without proper distribution Equipment

Analog Audio Characteristics

• Left and Right stereo on two BNC connectors
• High-impedance (1K ohm) line level inputs
• Analog Audio Volume Control with Muting provided
• Analog Audio is not supported for RGBHV video applications:
• Connectors are used for H&V
• Digital Audio Characteristics
• Standard digital PCM coax format on one BNC connector

Control and Monitoring

• Select one of four input sources for each of the two outputs
• Front-panel LEDs indicate the selected input, for each output

Control via:

• Front panel pushbuttons
• IR remote control, with extensive commands and control
• IR Extender
• Wired IR
• All control systems with RS-232 (cable supplied only with Fat Boy expansions)
