Extron SMX-300 DVI Matrix 8:8

The SMX System MultiMatrix Series of digital and analog multi-plane matrix switchers combines multiple, independent matrix switchers in a truly modular, field-configurable frame. Available in frame sizes from 2U to 5U, the SMX is capable of supporting up to 10 separate matrix boards for independent or simultaneous switching under a single point of control. It combines the proven reliability and high performance of Extron's CrossPoint®, MAV Plus, and MVX Series matrix switchers with the efficiency of a modular matrix switcher design. The SMX System is ideal for medical imaging systems, conference and training facilities, and other mid-sized applications that require the switching of different signal types in a cost-effective upgradable solution.


  • Combines multiple, independent digital and analog matrix switchers in a truly modular, field-configurable frame
  • Choice of 2U, 3U, 4U, or 5U frames — Four frames provide four, six, eight, or ten matrix board slots, respectively.
  • Choose from digital, fiber optic, analog, wideband, and stereo audio matrix boards — A full range of matrix boards is available for the SMX System MultiMatrix in I/O sizes of 4x4, 4x8, 8x4, 8x8, and 16x16.
  • Single point of control for up to 10 separate switching planes — Up to 10 matrix boards can be installed in an SMX frame and controlled from a single SMX front panel controller or control port.
  • Hot-swappable matrix board slots allow installation and replacement of matrix boards in three easy steps — Matrix boards can be changed or added without the need to disconnect power or remove the SMX frame from the equipment rack.
  • Field re-configurable and updateable — Matrix boards can be installed, removed, or replaced in the field with a minimum amount of configuration and set up required.
  • Enhanced QS-FPC™ - QuickSwitch Front Panel Controller — Provides a discrete, backlit button for each input and output, allowing for simple, intuitive operation.
  • Global presets — Frequently used I/O configurations may be saved and recalled either from the QS-FPC™ - QuickSwitch Front Panel Controller, Ethernet, or serial control. This time-saving feature allows I/O configurations to be set up and stored in memory for future use.
  • 10 presets per switching plane — Up to 10 presets per switching plane can be saved and recalled without affecting the other I/O plane connections.
  • Front panel security lockout — Prevents unauthorized use in non-secure environments. In lockout mode, a special button combination is required to operate the switcher from the front panel controller.
  • Virtual Plane Grouping — Switching planes can be grouped together to make a single, virtual switching plane. Plane grouping allows several signal planes to act as a single unit with a single control command affecting all planes.
  • RS-232 and RS-422 control port — Using serial commands, the SMX System MultiMatrix can be controlled and configured via the included Windows-based control software, or integrated into a control system. 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 RS-232 and RS-422 port also makes it easy to install firmware updates.
  • Front panel configuration port — A 2.5 mm mini jack is available for set-up and configuring the SMX without having to access the unit from behind the rack.
  • Control software — Provides a graphical, drag-and-drop interface for I/O configuration and other customization functions via RS-232 and RS-422 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.
  • Ethernet monitoring and control — Engineered to meet the needs of professional AV environments, Ethernet control enables the SMX System MultiMatrix to be proactively monitored and managed over a LAN, WAN, or the Internet, using standard TCP/IP protocols. Ethernet control provides for remote selection of input and output ties, adjustment and control of audio input and output levels, and advanced system diagnostics.
  • Rack-mountable metal enclosure — All SMX System MultiMatrix Switchers are housed in 19-inch wide metal enclosures.
  • Highly reliable, energy-efficient internal universal power supply — The 100-240 VAC, 50/60 Hz, international power supply provides worldwide power compatibility with high demonstrated reliability.
  • Redundant Power Supply - On select models — SMX frames are available with a redundant power supply for mission-critical applications.
