What is one of the main purposes of a cascading AV switcher?

A cascading AV switcher is primarily designed to allow multiple sources to be managed easily. In an audiovisual setup, where different video and audio sources may need to be routed to multiple displays or output devices, a cascading switcher enables you to connect several switchers together in a series. This creates a larger, scalable system that can effectively manage and switch between many input and output signals without requiring complex rewiring or manual changes.

This setup is especially beneficial in environments such as conference rooms, event venues, or educational settings, where multiple presentations may need to be accessed rapidly. By managing sources efficiently, it streamlines the operation, ensuring that content can be displayed as needed without interruption, thus enhancing the workflow of AV systems.
