Troubleshooting: VEL Teacher Station

VEL

The teacher station in the VEL 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 rack on the desk to the right of the teacher station. The HDMI Selector allows you to switch between different sources easily; simply use the number that corresponds to your source under Input Selector. Unless otherwise indicated bellow, 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 as the source. To do so, press the "HDMI 1" button on the remote, located in the silver-colored section in the middle area of the remote.

For any projection source, you'll need to make sure the audio on the rack is set correctly.

Look at the topmost panel on the rack and make sure all the volume knobs are set to the middle position (white lines pointing straight up).

  • Make sure the volume on the computer is turned all the way up. You can check by clicking on the volume icon in the top right of your screen
  • Ensure that you are outputting audio through Blackmagic Audio. Do this by holding down ALT and clicking on the volume icon in the top right of the screen. Select "Blackmagic Audio" from the dropdown menu.

  • 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.  

Desktop

To display the desktop of the teacher station, change the Input Selector on the rack to 1.

There are two main ways to display the desktop - as a mirror of the teacher station screen, or as a second monitor. Which you choose depends on how you like to project your screen, but note that mirroring can distort both displays. To toggle between these two, open System Preferences and choose the "Displays" option. Under the Arrangement tab, toggle "Mirror Displays" on or off.

Full-screen from Avid

There are two ways to get full-screen playback from Avid - from the software or out the Blackmagic I/O.  While image quality is better coming out the Blackmagic I/O, you may find it easier to toggle full-screen from within the application.

 

Full-screen from Application:

To enable full-screen (Shift+Cmd+F) within the application, simply disable the Hardware by clicking on the Hardware/Software button in the timeline window adjacent to the volume meters.  You should see a red circle with a line indicating that the Blackmagic hardware is being bypassed.

Your Laptop

To display your laptop's screen, you'll need an HDMI or VGA cable to connect to the visitor ports. You can check either out from the Lab Assistant in room 810. Once you are connected, change the Input Selector on the rack to 4, and your screen should display.

Blu-ray/DVD

To display a Blu-ray or DVD, power on the Panasonic player in the rack. Change the Input Selector on the rack to 2. The Blu-ray player should now appear on the projector. The remote control for the player can be found on top of the rack.

VHS/Other Decks

To play a VHS tape, you'll first have to check out the VHS deck and an RCA cable from the Lab Assistant in room 810. Connect the VHS deck to power and then connect the RCA cable to the righthand RCA outputs on the back of the VHS deck. Connect the other end of the RCA cable to the three RCA inputs in the teacher station rack. Change the Input Selector on the rack to 4, and switch the projector's mode to "Video/S-Video" using the 4 button on the projector remote. Use the controls on the VHS deck itself to control playback.

Any other decks behave in the same manner, simply connect the RCA cable to the appropriate RCA outputs from your deck.
