Audiovisual equipment in classrooms

On this page we summarize some guidelines regarding the use of the (audiovisual) equipment in the classrooms at Ghent University.

In the video below, we take AUD B Walter Soete in building T2 of the Technicum as an example.

Keys

To open the door of the classroom and/or desk:

  • use your badge, or
  • use your key, or
  • ask for a key from a receptionist, the dean's office or other contact person on the campus.

Important: Always lock the auditorium and the desk after use to prevent theft, damage, ...

Power

If the equipment inside and on inside the desk has no power, first turn on the general power switch. This button (if present in the classroom) is labeled and is normally located inside/on the desk.

Auditorium PC

Turn on the auditorium PC

  1. Turn on the auditorium PC inside the desk
  2. Log in with your UGent username and password
  3. Let the computer fully boot up until the desktop appears
  4. Select the appropriate input channel 'PC' for the projector

Choose the right image channel

  • 'PC' on the Extron console on the desk (this option is active when the button turns red), or
  • 'PC' on the switch inside the desk

Presentation on USB

If you bring your presentation on a memory stick, you can connect it to:

  • the console's USB inputs, or
  • on the side of the PC screen on the desk, or
  • on the auditorium PC

However, we recommend uploading your presentation in advance within the Ufora course and opening and playing it from there.

Laptop

Connect your laptop

  • to a power outlet
  • with the HDMI or VGA cable on the desk
  • with the internet cable on the desk

If you no longer have certain inputs on your device (e.g., USB, HDMI, VGA, Internet, etc.), bring a dongle that you will have pre-registered with the Netadmin team (ICT Department).

Choose the right image channel

  • 'HDMI' or 'VGA' on the Extron console on the desk (this option is active when the button turns red), or
  • 'Laptop' on the switch inside the desk

Sound system

Inside the desk

  1. an amplifier
  2. a charging station
  3. a headset with microphone

Sound level in the lecture recording/livestream

  • Always use the headset in the classroom. Only then you will also be audible in the lecture recording and/or livestream.
  • If the volume of the microphone in the classroom is good, it will normally be the same in the lecture recording and/or livestream.

Turn on the amplifier

Versterker geluidsinstallatie

  1. Turn on the amplifier using the 'Power' button
  2. Turn up the volume of the 'PC/laptop' channel halfway (if present on the amplifier)
  3. Turn up the volume of the 'headset' channel halfway (if present on the amplifier)
  4. Turn up the volume of the 'master' channel halfway (if present on the amplifier)
  5. Press the 'All' button at 'Speaker selector' on the amplifier (if present on the amplifier)

Turn on the headset

This instructional video shows how to operate the headset.

  1. Take the headset out of the charging station
  2. Switch the headset on by pressing the on/off button for 2 seconds (to do this, first open the front cover via the two side buttons)
  3. If the headset display shows the message MUTE, move the 'Mute' button at the top of the headset

Replace headset battery

This instructional video shows how to operate the headset.

  1. Remove the battery from the headset if the status is too low
  2. Place the empty battery in the charging station:
    • note the corners for the correct direction
    • the red light illuminates when the battery is charging
  3. Remove the charged battery from the charging station
    • the green light lights up when the battery is 100% charged
  4. Insert the battery in the headset (note the correct orientation)
  5. Always put the headset back in the charging station properly after use!

Still no sound coming through the speakers?

If the amplifier is on (see above) and the sound from your auditorium PC or laptop (e.g. a movie or audio clip played) still does not come through via the speakers:

  1. select the speaker icon on the auditorium PC or laptop
  2. select ExtronScalerD

  3. move the sound bar to the right until 100

Projection

Extron consoleTurn on the projector

  • Via a conventional remote control, or
  • Via the 'On' button under 'Display' on the Extron console on the desk (and wait until the 'On' button turns red). It takes about 40 seconds for the projector to fully boot up. During start-up, the 'On' button flashes. Please do not press anything until the projector is fully booted up.

Projection screen

This instructional video shows how to operate the projection screen.

Move the projection screen up and down via:

  • the Extron console on the desk, or
  • a conventional switch inside the desk, or
  • a conventional switch on the wall

Duplicate ScreenProjecting the computer screen

  1. Select the appropriate image channel 'PC' or 'Laptop' on:
    • the Extron console on the desk (this option is active when the button turns red)
    • the switch inside the desk
  2. Check that your desktop is displayed on the projection screen. If this would not happen automatically, you can use:
    • the console to briefly select 'Laptop' and then 'PC' again, or
    • the key combination Windows + P to duplicate the computer screen to the projector

Capture agent

Opencast PC

  1. Make sure the Opencast PC is on. Please never turn off this computer so that Team Multimedia can remotely troubleshoot any problems.
  2. Never disconnect cables from this Opencast PC. Otherwise you will endanger a lecture recording or livestream. This PC is normally correctly connected to the auditorium PC, the projector, the sound system, the Opencast camera, ...

Opencast screen

The Opencast screen on the desk displays 3 things:

  1. the sound level of the headset
  2. a preview of the camera image and the computer image
    • The camera image preview is a sequence of screenshots and not a live feed
    • The preview of the computer image is a live feed though
  3. the upcoming lecture recordings (date, time, title, ...)

If the Opencast screen does not show this information, it's best to:

  • turn on the screen, or
  • taking the screen out of sleep mode via the mouse or a finger, or
  • set the input channel of the display to "HDMI"

Opencast camera

  1. On the Opencast screen, check whether the fixed camera image is displayed. If not, switch on the camera via the remote control.
  2. Communicate to students that it is better not to sit in the front rows if they do not want to be recorded (e.g. for privacy reasons).

Remote control of the camera

The remote control of the PTZ cameras lies either:

  • inside/on the desk
  • with the ICT contact of the faculty or campus.

Via this remote control you can:

  • turn on the PTZ camera
  • setting presets via the number keys
  • restore the focus of the camera usually by pressing preset 1 or 2 once.

Recording light

The recording light of a capture agent can take on 3 different colors:

  • Green = The capture agent is ready for use, but there is no lecture recording in progress in this auditorium.
  • Red = There is a lecture recording going on in this auditorium.
  • Orange = There is a technical problem with the capture agent in this auditorium.

Lighting

  • Via the touch screen on the desk, or
  • Via a conventional light switch inside the desk, or
  • Via a conventional light switch on the walls

Darkening

  • Via the touch screen on the desk, or
  • Via a conventional switch inside the desk, or
  • Via a conventional switch on the walls
