Kramer SWT3-41-H 4x1 4K60 HDMI Switcher
 
The Kramer SWT3-41-H is a compact, professional 4x1 HDMI switcher engineered for reliable presentation and signage systems where signal integrity and hands-off operation matter. It supports 4K60 4:4:4 video with HDCP 2.2 and HDR, delivering pristine image quality for modern displays and sources. Intelligent auto switching selects the active input based on your preferred logic (priority or last-connected), while manual override is always available from the front panel. For audio, integrated audio de-embedding converts HDMI audio to a balanced stereo output on a 5-pin terminal block so you can feed a local DSP or amplifier in parallel with the HDMI path.
 
Deployment is straightforward. The unit offers RS-232 control, 6 GPIO, and a built-in IP gateway with browser-based setup, plus robust EDID management to ensure smooth handshakes between sources and displays. For device and network security, 802.1x authentication is supported. Installers can power the switcher over Ethernet via PoE or use the 5 VDC input, and they can automate power behavior on connected screens using CEC display control or serial commands. Housed in a fanless, aluminum DemiTOOLS enclosure, SWT3-41-H measures 7.50 x 2.35 x 1.08" (W x D x H) and weighs approximately 0.7 lb, making it easy to table-mount, or to place two side-by-side in 1U with the recommended rack adapter.
 
Ideal for conference rooms and classrooms, the SWT3-41-H combines high-bandwidth signal switching, flexible control, and simplified installation into a tidy, long-life form factor. It’s a trustworthy building block for corporate meeting spaces, training rooms, and anywhere UHD sources need to be switched cleanly to a single display.
