Environment
This applies to faculty, staff, and students using standard technology-equipped classrooms at Bowdoin College. Most of these rooms use a Crestron touch panel and a Mac Mini instructor computer.
- Who: Anyone presenting or teaching in a general-purpose classroom.
- Systems: Crestron AV control, Mac Mini instructor computer, in-room projector/display, and (in some rooms) Zoom or Microsoft Teams for conferencing.
Resolution
Most classroom issues can be resolved on your own with a few standard steps. Use the sections below for the type of issue you are seeing.
Audio issues
No sound coming from the instructor computer. Make sure the audio output is set to the correct device. In most rooms with a touch panel, output should be set to Crestron:
- Click the Apple menu in the menu bar.
- Click System Settings.
- Click Sound.
- Under the Output tab, select CRESTRON.
Note: There is usually more than one CRESTRON output listed. If you still have no sound, try selecting the other CRESTRON output.
No sound coming from Microsoft Teams or Zoom. When using the instructor computer, check the app's audio output:
- In Zoom, set the speaker output to Same as System.
- In Microsoft Teams, set the output to CRESTRON.
Remote attendees can't hear the room. This is usually caused by the wrong microphone being selected in your conferencing application. Select the room/Crestron microphone as the input device.
Video issues
If the instructor computer's display is not visible on both the touch panel and the projector — for example, the macOS login screen appears to be missing when the system is first turned on — press Command and F1 at the same time to "mirror" the Mac Mini to both the projector and the touch panel/monitor.
Computer issues
Instructor computer is not on. If there is no small pulsing white light on the front of the Mac Mini after you try to wake it with the mouse or keyboard, the computer is most likely off. Press the power button, located in the lower right-rear corner. After a few moments the computer should power on.
Note: The number and type of ports may vary from the ones shown above; however, the location of the power button will not change.
Classroom etiquette
Classrooms are used by many people throughout the day. Please do your part to keep them working for everyone:
- Don't power off the computer. When you finish class, log out to protect your data and ready the computer for the next person, but do not shut it down.
- Don't unplug anything from the computer. An HDMI cable with a USB-C video adapter is available in every room for personal laptops, and wireless presentation via Apple TV or a Solstice Pod is available in many spaces.
- If you do unplug something, be sure to plug it back in exactly where you took it from.
- Unless another class is coming in right behind you, please shut down the AV system using the touch panel (or shut down the projector in rooms that only have projection).
