Omega™ 4K / UHD Three-Input Switcher
for HDMI and USB-C with HDBaseT and HDMI Outputs
AT-OME-ST31
The Atlona AT-OME-ST31 is a 3×1 switcher and HDBaseT transmitter with HDMI and USB-C
inputs. It features mirrored HDMI and HDBaseT outputs and is HDCP 2.2 compliant.
The USB-C input is ideal for AV interfacing for newer Mac®, Chromebook™, and Windows®
PCs, as well as smartphones and tablets. Video signals up to 4K/60 4:2:0 can be transmitted
over HDBaseT up to 330 feet (100 meters). All inputs and the local HDMI output support 4K HDR
and 4K/60 4:4:4 at HDMI data rates up to 18 Gbps. Additionally, 4K downscaling to 1080p is
available for the HDMI output when connected to an HD sink. The OME-ST31 is designed for use
with Omega™ Series receivers and switchers, select HDVS Series receivers, the AT-UHD-EX-
100CE-RX receiver, and other Atlona switchers with HDBaseT inputs.
This switching transmitter can serve as an integral component of a fully automated AV system,
with the convenience of automatic input selection and display control. It can be remotely
powered by Atlona HDBaseT-equipped devices through Power over Ethernet (PoE). With the
optional power supply (Part no. AT-PS-245-D4), the OME-ST31 can provide PoE-powering to a
compatible receiver, and also charge laptops and mobile devices through the USB-C port. For
additional integration convenience, the OME-ST31 features analog audio embedding (to replace
the HDMI or USB-C input audio), control via TCP/IP and RS-232, RS-232 insertion over HDBaseT
and remote management with AMS (Atlona Management System).
