## Long description

The Kramer SWT3-21-HU-TR is a high-performance 2x1 switcher and extender designed for professional AV environments. This versatile device supports 4K60 4:4:4 video signals and features both USB-C and HDMI connectivity. Housed in a durable aluminium chassis, it provides reliable signal transmission over HDBaseT 3.0 technology, making it an essential component for modern collaborative workspaces and hybrid meeting rooms.
Advantages
This switcher offers exceptional flexibility by allowing the HDBaseT 3.0 port to be configured as either a transmitter or a receiver, depending on your installation needs. It simplifies hybrid meetings by enabling seamless switching between AV and USB host inputs, allowing participants to share content with both local and remote attendees effortlessly. The built-in USB-C docking capability supports device charging, while the intelligent EDID processing ensures plug-and-play compatibility with various displays. Additionally, the unit features audio de-embedding for professional sound systems and provides comprehensive control options, including IP, RS-232, and IR, reducing the need for external gateways.

How to use
To use the Kramer SWT3-21-HU-TR, first determine if the unit will function as a transmitter or a receiver and configure it accordingly during power-up. Connect your video sources, such as a laptop via USB-C or an HDMI device, to the appropriate input ports. Connect your display or projector to the output side. For extended setups, use a high-quality twisted pair cable to link the HDBaseT ports. Once connected, the auto-switching feature will detect active signals and route them to the display automatically. You can manage settings, firmware updates, and signal routing via the embedded web interface or local control buttons.
What to consider before purchase
Ensure your infrastructure supports HDBaseT 3.0 for optimal performance.
Verify that your USB-C devices support DP-Alt-Mode for video output.
Check the power requirements and available space for the 190mm x 116mm x 27mm unit.
Confirm the compatibility of your existing control systems with the unit's IP, RS-232, or IR interfaces.
Usage recommendations
For the best performance and maximum extension reach, always use high-quality, shielded twisted pair cables as recommended by Kramer. Ensure that the unit is placed in a well-ventilated area to maintain optimal operating temperatures during extended use.
