HDBaseT Extender with USB-C and HDMI Inputs

The Atlona AT-OME-ST31A-KIT is an HDBaseT transmitter and receiver combination that delivers a complete integration solution with 4K video extension, automatic switching for the USB-C and HDMI inputs, and automatic display control. It includes the Omega™ Series AT-OME-ST31A three-input HDBaseT switcher and AT-OME-RX11 HDBaseT receiver. The OME-ST31A features audio de-embedding, mirrored HDMI and HDBaseT outputs, and selectable 4K downscaling to 1080p for the HDMI output. The OME-RX11 features a compact, low-profile enclosure that can easily be concealed behind a wall-mounted display or above a projector. This HDBaseT extender solution extends AV, Ethernet, and control up to 330 feet (100 meters) over category cable. Audio de–embedding is available at the transmitter and receiver

The transmitter is remotely powered by the receiver over HDBaseT. This makes the OME-ST31A-KIT ideal for applications in which the transmitter needs to be installed under a meeting table or in a lectern where local AC power may not be available.
