Modular Presentation Routers (MPR)

These 350MHz  Modular Presentation Routers (MPR) provide full-matrix, RGBHV vertical interval switching.

  • 350 MHz
  • Vertical Interval Switching
  • Active, full-matrix switching
  • Fully buffered crosspoints
  • RGBHV
  • Balanced Stereo
  • RS232 Control

Applications:

  • Broadcasting
  • Board Rooms
  • Conference Rooms
  • Education
  • Home Theater
  • Retail Display

Matrix configurations of 12x8 and 8x4 are available with or without balanced stereo audio.  Audio-follows-video or may be routed separately.  Fully buffered, ultra-high bandwidth crosspoints allow a variety of source signals including NTSC, PAL, Y/C, YUV, VGA, and UXGA to be switched simultaneously without any crosstalk.  Featuring wide-range H&V, high-resolution sources such as graphics generators, PC's and workstations may be routed to several downstream devices such as data monitors and LCD projectors without loss of resolution. 

MPR switchers offer several control options including front panel pushbuttons, contact closure, and RS232 serial control.  Communicating via a simple ASCII protocol, controlling Knox routers by most third-party systems is seamless.  Windows software is also available for control from a laptop or computer.  Non-volatile memory enables route patterns to be stored for later recall.  MPR switcher also feature auto-switch and auto-search modes that can be toggled on/off from a rear panel jumper.
