Sem1 AVclassrooms
Seminar 1 Newly renovated for the spring 2026 quarter, Sem1 contains numerous AV classrooms, most of which support Hy-flex integration. We are developing resources as the contractors complete our AV system installations, and hope to grow this into a complete training and reference resource for these spaces.
status note: as of April 3, 2026 AV systems in Sem1 are still undergoing commissioning work. They are mostly complete, and a punch list has been submitted to our project manager so the contractor can address the remaining aspects. Please bear with us as we endure this crossover transition of using classrooms and technology before it is fully completed.
Training
System
- The Audio Video systems of Sem1 classrooms are controlled via touch panels. Larger rooms have touch panels on the lectern, smaller rooms have a 3-inch touch panel mounted on the wall. For more details, visit the Touch Panel Overview.

- The Sem 1 - Classroom AV racks hold the core of each classroom's AV system in a wall mounted enclosure. The Mac Mini is mounted here, and there are 2 USB-C ports on the front (we will soon be adding a USB-A hub on one of these) for connecting peripherals you may want to use.

Catchbox Mics Lanyard/Clip Mic - The power button is on the back - it is behind the clip!
Is there some way to turn on the mini mac? Yes, next to where the face of the mac mini shows in the rack, just down from one of the corners is a black button - that is attached to a mechanism that depresses the power button on the bottom of the mac mini. So if its off, tap that should bring it on. Its also possible if it is in standby the keyboard may be able to wake it. under normal conditions they don't need to be turned off, they will go to a powersave mode when not in use, and reboot at 7AM every day.
