How to Use Rangos Self-Service AV Equipment

  • A screen, projector, and speakers

  • Two cameras for video conferencing

  • A touch panel and equipment cabinet

CMU community members can request to use this equipment for meetings or events hosted in one of these three spaces. If you intend to use multiple spaces and/or the stage, you must request event support services.
