The MVX 48 VGA A is a 4x8 VGA 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 48 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.
  
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.
  
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.
  
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.
  
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.
  
Optional 
    IR 501 handheld remote control
  
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.
