Product Overview

SWT3−81−PR is a high−performance video processing and fast−switching scaling switcher with coupled AV + USB routing. It has eight USB−C and HDMI/USB inputs, one interchangeable HDBaseT 3.0 input or output port, and mirrored HDMI output. The unit supports both local and remote content sharing and multi−view presentation capability. The switcher has integrated audio DSP and a rich set of analog and digital interfaces, for high−quality audio−visual experience during hybrid sessions in meeting spaces and halls.

Key Features

Premium Presentation Switcher — High–resolution scaling switcher with AV + USB routing
Fast <1sec AV Routing — Clean and instantaneous routing between switcher inputs and outputs, with smooth and uninterrupted transitions
Dual–screen (MST) USB–C signal routing from one of the USB–C presenters to a local and remote display
Advanced video processing for multi–view presentations including side–by–side and picture–in–picture effects
High–Performance Scaling Experience — Built–in ProcAmp high–resolution scaling technology for optimal up or down image scaling
Enhanced Audio capabilities — Integrated echo cancelling and audio enhancement DSP for clear sound distribution to space deployed speakers. Both analog and digital audio interfaces with audio embedding and de–embedding capabilities with flexible and easily managed audio routing.
Built–in IP–based control capabilities, enterprise–grade IT–networking and security, and optional enterprise site management.
BYOD Ease and Convenience — Connect any DP–Alt–Mode–capable USB–C device as an AV presentation source and share content of either one or dual screens. The BYOD will enjoy AV display access, USB device access, ethernet connectivity and charging.
Hybrid–meeting Collaborative Sessions — The switch enables deployment of either BYOD or UCC (MTR, Teams Room or similar) in the same meeting space. The display system and the USB devices may be hosted by either a BYOD device or a UCC with flexibility to deploy the UCC on any side of the HDBaseT link.
High Performance Standard Extension — Professional HDBaseT 3.0 extension, for multi–signals distribution over extended–reach twisted–pair copper infrastructures
Intelligent IP based switcher management. — Device may be controlled using a WEB GUI or by a controller utilizing Kramer’s P3K commands.
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, ensure secured remote end–user communication, customer operation, and switcher management.
Easy and Elegant Installation — Highly integrated and compact device, with single cable connectivity for both HDBaseT signals and PoE power distribution to paired endpoint, substantially saves on space and solution wiring, mounting and installation, integration, and other associated deployment costs.
