Kramer Electronics 20-80548090 4x1 Hdmi Switcher

Product Description

The KRAMER ELECTRONICS 20-80548090 is a 4x1 HDMI switcher designed to consolidate four HDMI video sources into a single display output. It supports 4K60 resolution at full 4:4:4 chroma sampling, preserving color fidelity at high frame rates without subsampling. AV integrators and low-voltage technicians install this unit in boardrooms, control rooms, home theaters, and commercial AV rack systems where multiple source devices must share one display. The switcher handles demanding signal requirements for modern 4K content delivery over HDMI infrastructure.

This switcher fits installations where up to four HDMI sources such as media players, computers, cameras, or streaming devices need to route to a single HDMI-equipped display or presentation system. It is suited for both permanent rack-mount installations and flexible desktop AV setups in commercial and residential environments. AV professionals and systems integrators are the typical installing trade for this category of signal processing accessory.
