UMX Series Switcher for VGA, DVI-I, HDMI and DisplayPort with Audio embedding

Part No: 9156 0001 

UMX‑HDMI‑140 switches universal 4K video and audio to an HDMI output port. This device was designed for digital and analog video and audio signals: VGA, YPrPb, DVI, HDMI 1.4 and DP 1.1 with analog stereo audio from local inputs or embedded 7.1 HBR audio. The unit can also handle HDCP encryption. Analog signals (both audio and video) are converted into digital format. Using the factory, custom or transparent EDID emulation the user can fix and lock EDID data on each input connector. Advanced EDID Management forces the required resolution from any video source and fixes the output format conforming the system requirements.

The device can be mounted on a rack shelf or used standalone. UMX‑HDMI-140 is compatible with HDMI extenders and matrix switchers.
