Best Matrix Switchers for auditoriums

A hall rarely has one screen. It has the main projector, a confidence display facing the platform, an overflow room down the corridor and a feed to the recording rack, and they do not all want the same source at the same moment. That is the job a matrix exists for, and the count you need is outputs, which people habitually underestimate.

Protected content is the usual surprise. A source that refuses to appear on three destinations at once is behaving correctly, and the fix is planning rather than a different cable. Decide which destinations must carry protected sources before buying, and leave spare outputs, because the overflow room nobody mentioned always arrives later.
