5-Port 4K 60 Hz ARC Switch

The Mrocioa UK520-ARC connects five HDMI sources to a single display while passing audio return channel signals to a soundbar or receiver. It suits home-theatre owners who want to route multiple 4K devices through one TV input and keep external audio active across every source. Builders needing more than five inputs or 8K bandwidth should look elsewhere.

ARC on Port 1

Port 1 carries ARC and eARC audio back to the connected audio system, so sound follows the video even when you switch to ports two through five. If audio drops out, switching to port one for roughly 30 seconds restores the return path. The display must support ARC or eARC and Sonos users should disable auto switching.

Multifunctional Remote & Auto Switch

The bundled remote controls the switch and can also manage volume, playback and power on nearby CEC devices, replacing several handsets. Holding the switch button for three seconds or pressing the remote auto key toggles automatic input detection, letting you choose between hands-free switching and manual selection.
