You can play a DVD/BluRay through the computer or through the BluRay player in the rack The remote for the player is located in the 810 Annex.

  • Retrieve the remote from the 810 annex.
  • Insert the disk into the player in the rack
  • Change the Input Selector on the rack to 2
  • The remote control for the player can be found behind the monitor of the teacher's station.




Check the topmost panel on the rack and make sure all the volume knobs are set to 6


  • Control the volume using your regular Mac keyboard buttons.
  • Audio output should be set to "Headphones" for the classroom speakers. To use the headphone jack on the USB hub, select "USB audio CODEC."


If you can't hear audio in an editing program or when viewing your clips in finder, try playing a YouTube video. If the audio works, that indicates that the problem is with the program or your clips.  

Open the NLE's Audio Preferences and make sure that the output is set to Headphones.
