Troubleshooting: DPL2 Teacher Station

Overview

The teacher station in DPL2 has the ability to project from the desktop, your laptop, a DVD or Blu-ray, or an external VHS deck. All of these options are controlled via the HDMI switcher in the rack to the right of the teacher station. Simply use the number that corresponds to your Source under Input Selector.

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.  See Troubleshooting Audio guides here for more assistance.
