KRAMER SWT3-31-HU 3x1 4K60 USB–C/HDMI Switcher
SWT3−31−HU is a high−performance auto−switcher with one USB−C and two HDMI/USB inputs and HDMI output. The connected USB peripherals, such as a room camera and microphone, are switchable for use of the active USB host, for convenient hybrid meeting operation with both room and online participants. 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 — 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 USB 3.2 Switching — USB 3.2 signals switching, enables high data–rate connection between active USB host and space USB devices, such as 4K camera, high–quality audio devices, and HID (Human Interface Devices) mouse or keyboard devices. HDMI Mirroring — Active USB–C or HDMI input signal is mirrored to 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). K–Pair Support: — Automatically switches upon connection or disconnection of a local or extended input. Auto Switcher Ease of Use — Automatically plays the signal of the plugged source on the connected display with either last–connected or priority–based pre–selection. 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 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 Network Connection — Standard IT–grade 802.1x authentication for secured IT LAN connectivity. Comprehensive Management — Local panel indication LEDs to 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 2 units in a 1U rack space with the recommended 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
Applications Enterprise and education hybrid huddle spaces. Hybrid user connection element in advanced hybrid meeting solutions.
