Atomos Connect-AC H2S HD/SD-SDI to HDMI Adapter

$25.98

The Atomos Connect-AC H2S Converter with AC Cable is a compact, robust solution designed to integrate HDMI sources, like cameras or consumer devices, into professional environments that rely on SDI infrastructure. This model is powered by a standard figure-of-8 AC cable, offering a reliable power source for fixed installations without the need for external power bricks or managing batteries, unlike its battery-powered counterparts in the Connect line. The converter takes a single HDMI input and provides two duplicated 3G/HD/SD-SDI outputs, allowing connection to multiple professional monitors, switchers, or other equipment simultaneously.

It supports a range of standard formats, including 1080i60/50 and 1080p30/25. The device features a durable metallic housing designed for professional use. In addition to its primary conversion function, it includes professional test tools such as a built-in test pattern generator, an audio test tone, and 2:2 pulldown removal/insertion for seamless frame rate conversion. It even has a "flashlight mode" for working in dimly lit locations, a practical touch for on-location setups. For studio integration, it can be rack-mounted using an optional kit that holds up to four Connect-AC units.

About the Atomos Connect-AC H2S HD/SD-SDI to HDMI Adapter

The Atomos Connect-AC H2S is a compact, bidirectional converter designed to bridge the gap between professional SDI video signals and consumer/professional HDMI displays or capture devices. This versatile adapter facilitates two-way conversion, allowing users to convert HD or SD-SDI signals to HDMI, and HDMI signals to SDI. This bidirectional functionality makes it an invaluable tool for field producers, videographers, and broadcast engineers who work in hybrid environments where equipment with different interfaces must interact. For example, it can enable a camera with an SDI output to feed an HDMI monitor or recorder, or conversely, allow an HDMI source like a laptop or game console to feed an SDI-based production switcher or distribution system. Its plug-and-play operation requires no external power or software configuration, drawing minimal power directly from the connected HDMI port, which maximizes portability and ease of use in run-and-gun situations.

The device is engineered to maintain high signal integrity across the conversion process. It supports a wide range of common video formats in both standard and high definition, automatically detecting the input signal and outputting a corresponding signal in the target format. When converting from SDI to HDMI, it handles embedded audio extraction, passing the audio to the HDMI output. Conversely, when converting HDMI to SDI, it embeds the HDMI audio into the SDI stream. This ensures a complete audiovisual signal is maintained regardless of the conversion direction. The compact, durable metal housing is built to withstand the rigors of field use, and its simple, connector-only design (featuring one SDI and one HDMI port) eliminates any confusion, making it an intuitive and reliable problem-solver on set or in the control room.

Practical applications for the Connect-AC H2S are extensive. It can serve as a critical backup link, enabling a monitor to be connected to a camera's SDI output if the primary HDMI port fails, or allowing a director's HDMI tablet monitor to tap into a broadcast SDI feed. Its ability to derive power from the HDMI connection means one less cable and power adapter to manage, which is a significant advantage in fast-paced production environments. By providing a reliable, transparent, and powerless bridge between two ubiquitous video standards, the Atomos Connect-AC H2S empowers content creators to overcome interface compatibility issues quickly and focus on capturing and monitoring their content without technical interruption.

Key Features

  • Converts HDMI signal to two SDI outputs.
  • Integrated test pattern and audio tone generator.
  • Features 2:2 pulldown removal for smooth video playback.
  • Powered via a convenient, standard figure-of-8 AC cable.
  • Compact, durable metallic construction with built-in flashlight.
