What is an AV selector box?

An AV selector box is a device used to switch between multiple audio and video sources, allowing users to choose which input to display on a single output device, such as a television or projector. It typically features various input ports for different devices, like DVD players, gaming consoles, and streaming devices, and a single output port for connecting to the display. This enables seamless switching without the need to constantly plug and unplug devices. AV selector boxes are commonly used in home theaters, classrooms, and professional AV setups.
