Troubleshooting: DPL2 Teacher Station


    The teacher station in DPL2 has the ability to project from the desktop, your laptop, a DVD, or Blu-ray. All of these options are controlled via the HDMI switcher (red buttons) in the rack to the right of the teacher station. Simply use the number that corresponds to your input


    • Input 1: Teacher Station Computer
    • Input 2: Blu Ray Player
    • Input 3: HDMI input (open HDMI port on the rack)
    • Input 4: Visitor HDMI (cable hanging under the desk)



    Unless otherwise indicated below, you need to use the projector remote (white) to first turn on the projector (this may take a minute to warm up) and then to select HDMI 1 as the source.

    To play audio from your laptop, use the auxiliary cable and check your laptop's output.



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

    Playback through Computer

    • Insert the disk into the silver player/burner attached to Teacher Station via USB
    • Launch DVD Player for a DVD or BluRay4Mac for a BluRay.  Note that sometimes this app can be glitchy.

    Playback through Blu Ray Player

    • 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 the middle position (white lines pointing straight up).


    • Control the volume using your regular Mac settings on the keyboard.
    • Ensure that you are outputting audio through the Headphones output. Check this by clicking and holding the volume icon in the top right of the screen. Select "Headphones" from the dropdown menu.  To use the headphone jack on the 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.
