The Atlona AT-HDVS-TX is a versatile source switcher and HDBaseT transmitter designed for commercial audiovisual installations. It integrates two distinct source inputs—HDMI and VGA with analog stereo audio—into a single unit that not only selects between them but also transmits the chosen signal over a long-distance HDBaseT link. This device simplifies system design in meeting rooms, classrooms, and corporate environments by providing presenters with flexible connectivity options for both modern (HDMI) and legacy (VGA) laptops, while delivering a unified, high-quality digital signal to a remote display or projection system via a single CATx cable. The built-in switching function allows users or control systems to seamlessly select between the connected sources without requiring a separate external switcher.

The transmitter takes the selected input, converts it to the HDBaseT format, and sends it along with embedded audio, bidirectional control signals (IR, RS-232), and Ethernet data over one standard CAT6a cable to a compatible Atlona HDBaseT receiver, typically located near the display. This enables transmission distances up to 100 meters (330 feet), far exceeding the limitations of direct HDMI or VGA cables. The device supports high-definition video resolutions up to 1080p from both inputs and includes features like automatic input sensing and EDID management to ensure reliable handshaking with source devices. Power is conveniently supplied via Power over HDBaseT (PoH) from the receiver, eliminating the need for a local power adapter at the transmitter location and further streamlining installation. Housed in a compact, low-profile enclosure, the AT-HDVS-TX is engineered for discreet placement on or under a table, offering a robust and integrated solution for AV signal distribution and source switching in professional settings.
