MTX3−88−SE is a high−performance video processing seamless matrix scaler, with eight HDMI inputs independently routable to eight HDMI outputs. The matrix features an additional HDBT input and two mirrored HDBT outputs for local and remote presentation of high−quality seamless quad−views.

  • Powerful Multi–viewer — High–resolution flexible multi–view processor, simultaneously displaying dual quad–view presentations each from four inputs, or quad dual–view presentations each from two inputs, mirroring on dual remote displays.
  • Seamless Switching — Clean and instantaneous switching between inputs, with smooth and uninterrupted transition between presented content on displays, greatly enhances end–users' presentation experience.
  • High–Performance Scaling Experience — Built–in ProcAmp high–resolution scaling technology for optimal up or down image scaling and video signal auto–adjustment with output–connected display capabilities, to gain end–users' valuable high presentation experience.
  • High Performance Standard Extension — Professional HDBaseT extension, providing extended–reach signals over twisted–pair copper infrastructures, for remote input source, and mirrored matrix dual outputs content on remote displays. Conveying multiple audio–visual, Ethernet, control and power signals, matrix extension is standard that can be connected to any market–available HDBaseT–compliant extension products. For optimum extension reach and performance, use recommended Kramer cables.
  • Multi–channel Audio Transmission — Up to 32 channels of digital stereo uncompressed signals for supporting studio–grade surround sound.
  • Ethernet Extension — Ethernet interface data flows in both directions, allowing extension of up to 1 Gbps Ethernet connectivity for LAN communication and device control.
  • Bidirectional RS–232 Extension — Serial interface data flows in both directions, allowing data transmission and device control.
  • Bidirectional Infrared Extension — IR interface data flows in both directions, allowing remote control of peripheral devices located at either end of the extended line.
  • Audio De–embedding — The digital audio signal passing through to selectable outputs, is de–embedded, converted to an analog signal and sent to four stereo balanced analog audio outputs. This enables playing the audio on a locally connected professional audio system (such as DSP) and speakers, in parallel to playing it on the speakers connected to the AV acceptor devices (such as TVs with speakers).
  • HDMI Signal Switching — HDCP 2.2 compliant, supporting deep color, x.v.Color™, CEC, HDMI uncompressed audio channels, Dolby TrueHD, DTS–HD, 2K, 4K, and 3D as specified in HDMI 2.0.
  • I–EDIDPro™ Kramer Intelligent EDID Processing™ — Intelligent EDID handling, processing, locking and pass–through algorithm ensures plug & play operation for HDMI source and display systems.
  • Simple Control — Remote IP–controller connection, browser operation webpage, or local panel buttons, and eight multi–view preset configurations, for easy and fully flexible user ports selection, signals routing, multi–view switching, and matrix control.
  • Built–in Intelligent Control Gateway — Remote IP–driven intelligent serial control of connected devices to reduce installation complexity and costs, and to enable easy integration with control systems, such as Kramer Control.
  • Secured Operation — Standard IT–grade 802.1x authentication for secured IT LAN connectivity, and HTTPS secured web–UI browsing to provide secured matrix remote management and operation.
  • Comprehensive Management — Local panel–button operation, remote IP–driven firmware upgrade and management via user–friendly embedded web pages, and remote IP or local serial service and management via API commands and responses communication, for flexible service options and ensure lasting, field proven deployment.
  • Easy and Elegant Installation — Single cable connectivity for both HDBaseT signals and PoE power distribution with only a single power mains connection.


  • Control Center multi–view operations.
  • Seamless routable presentations in large–space facilities, such as conference halls, visitor centers, and auditoriums.
