Clark Library Audio Visual Equipment

The below information is legacy information,
this page will be updated with details of the new
ClarkTV equipment set-up by late-summer 2022.


Lectures and conferences at the Clark Library are held in the building’s elegant, wood-paneled drawing/music room. Due to the nature of the space, the AV equipment is portable and temporary. For each event requiring AV, a screen, audio system, digital projector, and “smart” podium are brought in. Presenters should know that the drawing room is 50′ long. Consequently, lecture attendees sitting at the back of the room might be 45–50′ away from the screen. The projector creates an image that is approximately 100″ wide on the screen. If you are preparing a digital presentation, 18–24 pt. fonts are the minimum recommended size for any text in your slides.

Please be aware that equipment at the Clark is permanently wired together for ease of use and reliability. As such, it is not possible to set up your own equipment in combination with the Clark’s (e.g., your own laptop cannot be hooked up and used for projection).

Speakers taking the time to familiarize themselves with the Clark’s systems and preparing their materials accordingly have had great success using the equipment. Please look over the list of equipment and its uses, and the hints and tips section.

All Clark equipment is maintained by technologist Alastair Thorne. Please contact him directly with any technical questions at alastair@humnet.ucla.edu.

Alastair will be happy to test your presentations on our equipment if they are sent to him at least two weeks in advance of the event at which you are speaking.

Hints & Tips

PowerPoint Presentations

  • If you plan on using audio in your presentation (music, video, sound effects, recorded spoken word etc.) please let us know at least 2 weeks before your presentation. [We need to do special wiring for these situations.]
  • Please bring your PowerPoint presentations on a CD, DVD-Rom, or on a USB keydrive.
  • Compress your pictures as jpegs, and resize them before putting them into your presentation.
  • If your presentation was created using standard fonts, text generated directly in PowerPoint, and jpeg digital photographs, it is very unlikely that you will encounter any compatibility problems.
  • Try to avoid placing text or images against the very edges of your slides. It’s a good idea to allow a 5–10% margin on all sides of a slide to accommodate different projection settings in different venues. [At the Clark our projector crops roughly 3% from the right and left edges of every slide.]
  • If your presentation contains linked or embedded elements from other programs’ unusual or premium fonts (e.g. musical notation, Sanskrit, Adobe Pro fonts, etc.), audio and video clips, or non jpeg photographs there is a small chance you may encounter some compatibility problems.
  • Make sure you bring separate copies of all the files used in your presentation as a safeguard (this is particularly imperative when using music and video clips).
  • Taking care to align your images and text-boxes consistently will avoid the appearance of pictures and text “hopping” around the screen as you move from slide to slide.
  • Our equipment uses PowerPoint 2016 and Keynote 9 (both are backward compatible with earlier versions).
  • One of the most effective means to incorporate audio and/or video in your presentation is to include clips directly into your PowerPoint presentations. This preparation avoids shuffling between equipment during your presentations and allows exact clips to be played. You can find very helpful tips regarding audio and PowerPoint here, and similar tips regarding video and PowerPoint here.
  • Controlling media with a mouse while presenting can be confusing. The following trick allows you to start and stop your media by simply advancing slides.
    1. When you create a slide with embedded media in it, duplicate the slide twice (right click on slide and select “duplicate slide”). You should now have three copies of your media slide.
    2. Delete the media element from copy #1 and copy #3.
    3. Set the media on slide #2 to play automatically.
    4. Now when you advance to slide copy #1, the audience sees your text/pictures but no music (or video) yet; then you advance to copy #2, and the music starts (but the text/image doesn’t noticeably change). When you advance to copy #3, the music stops.
      N.B. This trick only works with simple static slides (i.e., it won’t work with animated bullet lists, etc.). (If you want to play multiple media clips over the same text/image just create more copies.)
