The MVX 44 VGA A is designed to route high resolution computer-video and stereo 
audio signals. Convenient 15-pin HD connectors are used for all computer-video 
input and output connections. Unbalanced stereo audio is input on 3.5 mm stereo 
mini jacks, while balanced or unbalanced stereo audio is output on captive screw 
connectors. Using pre-terminated cable assemblies, such as Extron's VGA with 
Audio Cables, eliminates crimping and makes installations faster and easier.
In addition, the MVX 44 VGA A comes standard with the QS-FPC™ - 
QuickSwitch Front Panel Controller, which allows for touch-of-a-button input and 
output selection directly from the front panel. It can also be controlled 
through RS-232 serial control utilizing Extron's SIS™ - Simple Instruction 
Set commands, the optional Extron IR 501 remote control, the optional Extron MKP 
2000 or MKP 3000 X-Y remote control panels, or via a third party control system.
Features

  
  
　
  
Inputs: 
    VGA on female 15-pin HD connectors; audio on 3.5 mm stereo mini jacks
  
　
  
Outputs: 
    Video on female 15-pin HD connectors; audio on captive screw connectors
  
　
  
300 
    MHz (-3 dB) RGB video bandwidth, fully loaded — 
  Designed for routing most common high resolution computer-video rates without 
  signal degradation. The MVX Series provides a minimum 300 MHz (-3 dB) of RGB 
  video bandwidth at full performance capability when one input drives all 
  outputs.
  
　
  
Triple 
    Action Switching™ for RGB delay — RGB delay 
  blanks the screen when the matrix switcher switches to a new source. The new 
  sync signals precede the RGB signals, so there is no glitch during the 
  transition.
  
　
  
Switches 
    both balanced and unbalanced stereo audio — Output on 
  captive screw connectors.
  
　
  
Audio 
    input gain and attenuation — Allows users to set the 
  level of gain or attenuation for each audio input channel, eliminating 
  noticeable volume differences when switching between sources.
  
　
  
Switchable 
    audio output levels — Output levels can be switched 
  between +4 dBu professional and -10 dBv consumer levels, allowing a mix of 
  professional and consumer-level audio equipment.
  
　
  
Optional 
    IR 501 handheld remote control
  
　
  
Audio 
    breakaway — Provides the capability to break an audio 
  signal away from its corresponding video signal, allowing the audio and video 
  signals from one source to be switched to different destinations.
  
　
  
View 
    I/O mode — Easily view which inputs and outputs are 
  actively connected.
  
　
  
QS-FPC™ 
    - QuickSwitch Front Panel Controller — Provides a 
  discrete button for each input and output, allowing for simple, intuitive 
  operation.
  
　
  
Global 
    presets — Frequently-used I/O configurations may be 
  saved and recalled from the front panel or via serial control. This 
  time-saving feature allows you to set up I/O configurations and store them in 
  memory for future use.
  
　
  
Front 
    panel security lockout — Prevents unauthorized use when 
  the matrix switcher is installed in an unsecured environment where easy access 
  is not desirable. In lock-out mode, a special button combination is required 
  to operate the front panel.
  
　
  
RS-232 
    control port — Using RS-232 serial commands, the MVX 
  Series can be controlled and configured via the Extron Windows®-based control 
  program, or integrated into third-party control systems. Extron products use 
  the SIS - Simple Instruction Set command protocol, a set of basic ASCII code 
  commands that allow for quick and easy programming. The serial port also makes 
  it easy to install firmware updates.
  
　
  
Control 
    software — Provides a graphical, drag-and-drop 
  interface for I/O configuration and other customization functions via RS-232 
  remote control. This software also offers an emulation mode for configuration 
  of an offsite matrix switcher; the I/O configuration may be saved for future 
  downloading to the matrix switcher.
  
　
  
Optional 
    control panels and keypads — Optional X/Y control 
  panels, bus control panels, and keypads provide the flexibility to control an 
  MVX Series matrix switcher from a remote location.
  
　
  
1U, 
    rack-mountable metal enclosure
  
　
  
Internal 
    international power supply — For worldwide 
  compatibility, all models are equipped with an internal, autoswitching power 
  supply that meets or exceeds all appropriate safety certifications.
