Instructions on the use of the audiovisual technology in standard classrooms.
Standard Classroom Audiovisual System Instructions
The University of St. Thomas is currently in the middle of a multi-year classroom standardization project. As such we currently have three different types of AV systems in our standard classrooms. All classroom AV systems support projected video and amplified audio from either a designated instructor PC or a laptop and include a PTZ camera and boundary microphone for videoconferencing or lecture capture. What differs is how you interact with these systems.

This is our current standard.

System Control

To share a laptop – Press LAPTOP on the button panel.
Volume Control
Volume can be controlled at the button panel. It can also be controlled at the PC/Laptop and media players such as VLC and Youtube. Note that if any of these volume controls are turned down you may not hear any audio in the room.
AV Controls Software
This is an older standard where the AV system is controlled by software on the instructor PC.


System Control
To use the projector you must log into the room PC. Once logged into the computer a window that looks like the above left image should open. If it doesn’t, you can start the system by selecting the A/V Control icon on the desktop. After pressing START the above right A/V Control window (above right image) will open.
Source Selection
To share the room PC – Select COMP and then PC
To share a laptop – Select COMP and then LAPTOP
Volume Control
Volume can be controlled in the A/ Controls software. It can also be controlled at the PC/Laptop and media players such as VLC and YouTube. Note that if any of these volume controls are turned down you may not hear any audio in the room.
Remote Control
This is a simple interim standard where a remote control is used to turn the projector on and raise or lower the volume levels.

System Control
Press ON on the projector remote control to turn the projector on.
Source Selection
To share the room PC – The room PC is the default source that will display on the projector.
To share a laptop – When a laptop is plugged into the laptop HDMI cable the system will auto-switch to display the laptop. The system will default back to the room PC when the laptop is unplugged.
Volume Control
Volume can be controlled with the projector remote control. It can also be controlled at the PC/Laptop and media players such as VLC and YouTube. Note that if any of these volume controls are turned down you may not hear any audio in the room.
Hybrid Peripherals
The PTZ camera, boundary microphone and HoverCam work identically in all types of rooms. Please note that these can only be used with the room PC.
Using the PTZ camera and boundary microphone
- Position the panel microphone. It picks up audio best in front and to the sides of it, but directly behind the microphone pickup is weak.
- Start a Zoom call and ensure that within Zoom the correct microphone, speaker and camera are selected.
- Microphone = Microphone (USB Audio Codec)
- Speaker = ExtronScalerD (AMD High Definition Audio Device)
- Camera = PTZ Pro 2
- Use the Logitech remote control to adjust the PTZ camera.
Using the HoverCam as a Document Camera
- On the PC desktop, open the Flex 11 software.
- Once open, physically adjust the HoverCam over the paper document you wish to project on the AV system. Tip: Press the AF-L button on the base to lock the focus. Otherwise, focus tends to wander.
The HoverCam can also be used as a second camera in Zoom/Panopto and has a microphone.
