Main Hall Classroom Technology Guide

Turning On/Off the Projector

The A/V control panel is located next to the projection screen in Main Hall classrooms.

  • Press ON to turn on the projector. Allow 30 seconds for the projector to warm up before an image is displayed.
  • Press OFF when the projector is no longer needed.

Using the Lectern Computer

Each room is equipped with a built-in lectern computer. You do not have to turn on the computer, but if you do not see any display on the monitor, it might be in standby mode.

  1. Press any key on the keyboard to wake up the computer.
  2. If the computer does not resume from standby, you may power it on by pressing the power button.

    3. Connecting My Device

    If you have a personal device, i.e. laptop, you may connect it to Trinity’s audio/visual equipment using the built-in cable on the lectern. Main Hall classrooms only have HDMI connections available. If your device does not support HDMI output, you will need to bring the appropriate adapter for your specific device.

    1. Connect your personal device using built-in cable on the side of the lectern by lifting the panel cover plate and extending the wire.
    2. After your device is connected, press the Guest button on the A/V wall control panel.

    Adjusting the Volume

    You can adjust the classroom’s speaker volume using the Vol+ and Vol- buttons on the A/V wall control panel.

    Wireless Projection from Apple Devices

    All Main Hall classrooms are equipped with AirPlay technology, and can project wirelessly from Apple devices, including MacBooks, iPhones, and iPods.
