The Extron MPX 423 A

  Model Version Description Part #    
MPX 423 A    Media Presentation    60-683-01


The Extron MPX 423 A is a media presentation matrix switcher that merges four independent matrix switchers into a single, compact enclosure: a 4x2 VGA switcher, a 4x2 S-video switcher, a 4x2 composite video switcher, and a 12x2 stereo audio switcher. Compact and cost-effective, the MPX 423 A can be utilized for expanding the input capabilities of a typical projector or LCD display, while providing a second set of outputs for local or preview monitoring, or a second presentation system. This integrator-friendly matrix switcher is ideal for a variety of small-scale applications including classrooms, training and conference facilities, and sophisticated home theaters.

When switching the inputs of the MPX 423 A, the user can choose between the Single Switcher mode and Separate Switcher mode. Single Switcher mode turns the MPX 423 A into a single 12 input switcher that routes the signals of the input selected to the output of its group. Outputs of the other groups are muted. In Separate Switcher mode, the MPX 423 A becomes three switchers in one box, enabling independent switching to the output of any given I/O group. The MPX 423 A also offers a 12x2 audio switcher that can access the audio of all three video groups. Balanced and unbalanced audio inputs and outputs are provided on convenient captive screw connectors.

Control and configuration of the MPX 423 A is provided via the front panel, RS-232, and Ethernet. Housed in a 1U, full rack width metal enclosure, the MPX 423 A can be easily mounted into any rack or podium, or under a desk.
