Back row reads 10pt slides
Delay-ring PA aligns sound to furthest tier while 98" canvas or dual projection keeps spreadsheet detail legible from row K — students stop photographing slides blurrily. Lectern PTZ and doc cam feed overflow rooms and LMS so enrollment caps flex without building new wings.
