Professional Universal Matrix switcher in 4x4 I/O configuration

UMX4x4-Pro2 is an all-round Universal Matrix and a breakaway audio/video switcher. It is a perfect solution for dynamically changing environments such as small board rooms and classrooms.

Highlight features

  • Universal Matrix Switcher – accepts VGA, YUV, DVI and HDMI 1.3 signals on each input
  • All-in-one design concept
  • Separate audio and video matrix switching
  • Analog audio and video A/D conversion
  • Adjustable analog audio settings
  • HDCP compliant

UMX4x4-Pro2, the all-round Universal Matrix Switcher, is the perfect solution for ever-changing environments such as small board rooms and classrooms. UMX (Universal MatriX) technology was recently developed by Lightware to support various analog and digital audio visual formats. VGA, YUV, digital DVI, HDMI 1.3 with HDCP, stereo analogue and S/PDIF digital audio signals are all supported.

Each input port incorporates an individual EDID Manager, a video A/D converter and a digital/analog video switch. No frame delay occurs if an analog signal is digitized. Each port contains an auto sync function, but the picture parameters can also be fine-tuned manually. The built in Frame Detector and graphical signal analyzer helps make precise adjustments and our Pixel Accurate Reclocking technology provides exceptional signal regeneration capability. UMX4x4-Pro2 has the ability to input HDMI with embedded audio and DVI with HDCP encryption, VGA, component video and analog or digital audio. De-embedding audio from the incoming HDMI stream, re-embedding at output from a different audio source and even routing audio separately from video is easily handled with the UMX switcher.

With the additional features, such as RS-232 and IP control and a comprehensive software suite, the UMX4x4-Pro2 is our most powerful and adaptive matrix yet.
