Kramer SWT3-31 Overview
The SWT3-31-HU 3x1 4K60 USB-C/HDMI Switcher from Kramer is an intelligent 3x1 automatic switcher that can handle HDMI signals and one USB-C input with resolutions up to 4K60. The unit features two HDMI inputs, one USB-C input, an HDMI output, and an HDMI loop output, all compliant with HDCP 2.3. It supports audio de-embedding, remote IP-driven management, and intelligent EDID processing. The intuitive, plug-and-play device automatically determines priority or last-connected auto switching based on active video signal detection and can be powered using PoE (Power over Ethernet).
Hybrid-Meeting Collaborative Switching
Controllable coupled signals switching of both AV and USB host inputs for concurrent connection with AV output and space USB devices allows collaborative hybrid meeting where multiple meeting participants are switched to share their content with both room and online meeting participants.
BYOD Ease and Convenience
Connect any DP-Alt-Mode-capable USB-C device as an AV presentation source while providing the connected device with USB 2.0 and Ethernet connection, and (if PD-2.0-capable) up to 60 watts of power via a single USB-C cable connection only.
HDMI Signal Switching
The unit is HDCP 2.3 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.
HDMI Mirroring
Active USB-C or HDMI input signal is mirrored to HDMI loop output port for connecting a local monitor or adding an additional unit in a daisy chain.
I-EDIDPro Kramer Intelligent EDID Processing
Intelligent EDID handling, processing, and pass-through algorithm that ensures plug-and-play operation.
Audio De-Embedding
The digital audio signal passing through to the 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 or unplugged with user-defined shut-down delay.
Simple and Flexible Control
Remote IP-controller connection, browser operation webpage, local panel buttons, or remotely connected contact-closure buttons 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 AV, USB, and sensor devices via CEC, RS-232, IR, 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.
Comprehensive and Cost-Effective Management
Local panel indication LEDs facilitate easy local maintenance and troubleshooting. Remote IP-driven 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 MegaTOOLS fan-less enclosure for dropped-ceiling mounting or side-by-side mounting of two units in a 1 RU rack space with an optional rack adapter for easy switcher deployment.
Convenient Display Power On/Off Control
Simply press the DISPLAY ON button to toggle on and off the power of the connected CEC-enabled display with awareness of display power on/off status via button LED indication.
Easy Online Meeting System Integrated Connectivity
Built-in flexible auto-disconnection operation of USB devices, such as space cameras and soundbars, enable detection of BYOD presenter disconnection by online meeting systems for their auto-activation, convenient integration, and ease of end-user operation according to space changing hybrid sessions needs
