MMX8x4-HT400MC is a standalone matrix switcher specifically designed for conference room environments. It has four HDMI and four TPS (HDBaseTTM) inputs and four HDMI video outputs. 4K / UHD (30Hz RGB 4:4:4, 60Hz YCbCr 4:2:0), 3D capabilities and HDCP are fully supported. MMX8x4-HT400MC has a dedicated Special Audio Input block with input ports for microphone and line-in. The built-in sound mixer allows for free mixing of the microphone or the line-in and the deembedded audio from one of the input HDMI signals.

The Special Audio Input block includes a voice activation feature allowing the volume of the voice of a person speaking into the microphone to be automatically focused, and the volume of the rest of the sounds to be lowered as soon as the presenter starts speaking. The device also has one shared, balanced 5-pole Phoenix audio output for the built-in sound mixer.

Using factory, custom or transparent EDID emulation users 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 to conform to the system requirements.

The unit can be controlled via RS-232, Ethernet or USB ports, but it also offers RS-232, Serial and IR command injection capabilities allowing to send any control command directly from the LAN connection to end points.

The MMX8x4-HT400MC is compatible with both HDBaseTTM extenders and HDBaseTTM compliant displays.

The built-in Event Manager feature provides control via RS-232 and IR ports.

Advanced Control Pack Features:

  • 100 available event slots in ’Plus’ extenders
  • Support RS-232 protocol for communication and control of third party devices like VC codecs. This allows the Cisco Room Kit login on RS-232–USB connection.
  • Support to receive CEC commands for control of displays and Lightware Event Manager to automate room actions.
  • Support to send CEC commands on HDMI ports for control of other devices.
  • Support true Infrared messages using HEX codes to control TVs, media players and other devices with IR emitters.
