Kramer MTX3-44-HSA is a high−quality scaler−based matrix with four HDMI inputs independently routable to four HDMI outputs. The video scaling processor provides a seamless switching experience. Each HDMI output supports down− or up−scaling to account for sink / source capability differences. The integrated audio matrix – with two analog audio inputs and two analog audio outputs – supports routing of any digital or analog audio source to sink including ARC (Audio Return Channel) sources.
- Flexible and Safe Matrix Routing — Seamless, ultra–fast switching transitions, for unsurpassed end–user presentation experience.
- HDMI Signal Switching — HDCP 2.3 and HDMI 2.0b compliant.
- OSD — Displays a convenient OSD (On–Screen–Display) INFO screen, showing the unit’s IP settings, firmware version, video information, etc.
- IP Gateway support — CEC control messages to sinks or sources may be defined and generated using the IP control gateway mechanism.
- I–EDIDPro™ Kramer Intelligent EDID Processing™ — Individual EDID management per input for flexibly capturing and storing EDID from output–connected displays or custom files. Intelligent EDID handling and processing ensures plug & play operation for HDMI source and display systems.
- Audio Embedding and De–embedding — The unit includes 2 analog balanced stereo inputs and 2 analog balanced stereo outputs for flexible integration with professional audio systems, such as amplifiers, audio processors, and powered speakers.
- Auto–Output Shutdown — When no input signal is detected for an output, after a time period, the system automatically send a CEC command and shuts down the output display. When the input signal returns, the display is turned on once again.
- Simple Control — The unit is controlled over secured IP integrated web GUI and/or by any controller supporting Kramer’s P3K API commands.
