Product Information

SWT3−21−H is an intelligent 2x1 automatic switcher for 4K60 4:4:4 HDMI video signals, with plug and play user experience such as priority or last−connected auto−switching based on active video signal detection, and easy remote IP−driven management and control.

Auto Switcher Ease of Use — Automatically plays the switched source signal on the connected display according to user–configured preferences, such as priority or last–connected input. When the user manually switches, by pressing a button, the auto switching is overridden.

HDMI Signal Switching — HDCP 2.2 compliant, supporting deep color, x.v.Color™, CEC, lip sync, 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

Multi–channel Audio Switching — Up to 32 channels of digital stereo uncompressed signals for supporting studio–grade surround sound.

Audio De–embedding — The digital audio signal passing–through to the HDMI output, is de–embedded, converted to an analog signal and sent to the stereo balanced analog audio output. 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 device (such as TVs with speakers).

Display On/Off Operation — Meeting presentation is simplified by manually or automatically turning ON/OFF a CEC–enabled or serially–controlled display when the presentation source is plugged in / unplugged with user–defined shut–down delay.

Simple and Flexible Control — Remote IP–controller connection, browser operation webpage, local panel buttons, and remotely connected contact–closure buttons triggering configurable operation functions, for easy and fully flexible user ports selection, signals routing, and switcher control.

Built–in Intelligent Control Gateway — Remote IP–driven intelligent control of connected HDMI and sensor devices via RS–232 or I/O. Eliminating the need for an external control gateway, this feature reduces installation complexity and costs, to enable easy integration with control systems, such as Kramer Control.

Secured Operation — Standard IT–grade 802.1x authentication for secured IT LAN connectivity operation.

Comprehensive and Cost–effective Management — Local panel indication LEDs to facilitate easy local maintenance and troubleshooting. Remote IP–driven device firmware upgrade and management, via user–friendly embedded web pages and optional whole site management system, ensure lasting and field proven deployment.

Easy and Elegant Installation — PoE powering via LAN port connection, and compact DemiTOOLS® fan–less enclosure for user–reachable table mounting, under table, dropped–ceiling mounting, or side–by–side mounting of 2 units in a 1U rack space with the recommended rack adapter, for easy switcher deployment.
