Kramer MTX3−88−PR−PRO is a high−performance video processing and fast−switching scaling matrix, with independent audio−visual (AV) and USB routing. The matrix has unmatched flexibility with USB−C, HDMI, HDBaseT 3.0 ports, air−casting inputs and network stream output.
The unit is enhanced with audio capabilities including an integrated DSP, integrated dual−zone power amplifier, DANTE and USB audio routing.
The flexibility and processing power of the MTX3−88−PR−PRO makes it a perfect system for numerous deployment scenarios.
- Premium All–in–one Matrix — High–resolution scaling matrix with multi–signal routing of wired and wireless user interfaces.
- Dual–screen USB–C routing capability allowing to connect any Alt–mode DP capable laptop with an extended desktop to be displayed on any selected pair of outputs.
- Eight HDBaseT 3.0 extension ports with PoE remote device powering. Each HDBaseT 3.0 port has configurable direction (input or output) and can extend multi–signals over twisted–pair copper infrastructures for un–matched system flexibility.
- Advance video processing capabilities with several Multiview presentation layouts and two independent video wall presentations.
- Rich set of audio interface options including analog (line, microphone and speaker), Dante and USB audio devices.
- A sophisticated audio DSP configured by an intuitive graphic dash–board style user interface. The audio DSP allows mixing, condensing, expanding, noise filtering and echo cancelling to ensure echo–free, noise–free, and crystal–clear sound distribution.
- Fast <1sec AV Routing — Clean and instantaneous routing between matrix inputs and outputs, with smooth and uninterrupted transition between presented content on local and remote displays.
- Hybrid–meeting Collaborative Sessions — Controllable multi–signals routing of both AV and USB host inputs. AV and USB routing may be performed independently or in USB–follow–AV mode.
- Six local USB device ports divisible into two groups for enhanced host — device USB routing flexibility.
- 60W charging for USB–C connected devices.
- High–Performance Scaling Experience — Built–in ProcAmp & high–resolution scaling technology for optimal up — or down image scaling.
- Open Standard Streaming and Recording — Session content sharing and recording via the popular H264/5 open streaming standard over IT Lan and WAN networks.
- Room Control — Includes gateways and a rich set of relays, RS–232 and GPIOs to reduce the systems complexity offering the end–user a smooth and sophisticated room control experience.
- Standard Enterprise–Grade Secured Operation — Standard IT–grade authentication for secured IT LAN connectivity, and secured web–UI browsing and communication, with OWASP–10 (Open Web Application Security Project) standard penetration protection certification.
- Comprehensive Management — Local panel buttons operation, remote and secured management via integrated user–friendly web–UI server, and remote via IP–driven API control and management communication, for flexible service options and ensure lasting, field proven deployment.
