Versatile HDMI 2.1 Switcher 2×1 for AV Flexibility

The Gefen HDMI 2.1 Switcher 2×1 seamlessly switches between two ultra-high-definition HDMI sources and a single display. It supports up to 8K@30Hz (4:2:0) and 4K@120Hz (4:4:4), delivering sharp visuals and fast response times. Since it’s compliant with HDMI 2.1 and HDCP 2.3 standards, this switcher is an ideal fit for home theaters, gaming setups, and conference rooms that require fast and reliable AV source selection.

Advanced Audio Control with eARC and De-Embedding

To complement video switching, the switcher supports high-resolution audio formats such as Dolby Atmos®, DTS:X™, and LPCM. Additionally, it includes digital (SPDIF) and analog (3.5mm) audio outputs for easy integration with external speakers or AV receivers. With both ARC and eARC passthrough, users can return audio from a smart TV back to the AV system—streamlining installation and reducing cable clutter.

Flexible and Convenient HDMI Switching

Users can switch between HDMI inputs using an IR remote, DIP switches on the front panel, or auto-sensing mode. Furthermore, the switcher includes IP control via the built-in Gefen API, making it easy to manage from a control system. These options ensure smooth operation in both professional and residential AV environments.

Compact Design with Upgradeable Features

Because space often comes at a premium, the switcher features a durable, compact metal enclosure with LED indicators for input and power status. It also includes USB-C connectivity for quick firmware updates, helping to future-proof the system. Whether you mount it in a rack or place it behind a display, the unit is engineered for flexible installation.
