MMX8x4-HT420M is a standalone matrix switcher specifically designed for conference room environments. It has four HDMI and four TPS (HDBaseTTM) inputs with two HDMI outputs and two TPS outputs. 4K / UHD (30Hz RGB 4:4:4, 60Hz YCbCr 4:2:0), 3D capabilities and HDCP are fully supported.
MMX8x4-HT420M 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 audio signals from the de-embedded HDMI, the microphone or the line-in. 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 two balanced 5-pole Phoenix audio connectors at two of the HDMI inputs. The audio signal direction of the port can be changed with the Lightware Device Controller software, so these audio ports can be either input or output ports.
The audio signal presented by the built-in mixer is channeled to one shared, balanced 5-pole Phoenix audio output, including the mixed audio of a selected, de-embedded HDMI audio, the microphone and the Line-in.
PoE 48V remote powering is available on every I/O TPS ports for cost-effective installations.
MMX8x4-HT420M receives and transmits digital video, audio and control to a distance of up to 170m over a single CAT6 cable. Using 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 to conform to the system requirements. The unit can be controlled via RS-232, Ethernet or USB ports, but it also offers Ethernet, RS-232, Serial and IR command injection capabilities, allowing to send any control command directly from the LAN connection to remote end points.
The built-in Event Manager feature provides control via RS-232, IR, Ethernet, Relay and GPIO ports. The MMX8x4-HT420M is compatible with both HDBaseTTM extenders and HDBaseTTM compliant displays.
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.
