This guide will walk you through the basics of using the Hokin Hall (623-109) lecture hall. This hall has a large projection screen, a lectern on stage with a lectern computer, document camera and a guest laptop connection. This lecture hall also contains two cameras and microphones for hybrid learning/streaming events.
Select which section you would like to jump to or keep reading for the full guide.
To power on the audio/visual equipment, use the Press to begin button in the center of the lectern touchscreen (the small screen mounted to the lectern). If there is no image on this screen, touch it once to wake it from it's sleep state and then press the button. Once the button is pressed the classroom display will power on.
VIDEO SOURCES
Along the top of the screen are your video sources. Touch a button to display that source upon the screen.
Select Room PC if you would like to use the lectern computer. It is located below in the lectern. Look in the rack for the computer pictured below. The power button is on the left side of the computer. There are USB and USB-C ports on the front of the computer for flash drives.
You may need to power on the computer by pressing the computer's power button (a small circular button located on the front of the computer). On a Lenovo computer, you can tell if the computer is on or off by the small LED light in the middle of the power button. If it is lit, then it is already on. When the computer is powered off, the light is not lit. If you see a pulsing light on the power button, then the computer is in sleep mode. Try pressing a key on the keyboard or clicking a mouse button to wake the computer for use.
Once the computer has started, you will need to log in using your Columbia College Chicago credentials. You will need to use their Columbia College email address as the user name (example: jsmith@colum.edu) and the same password that they have chosen to access their email and other Columbia services. If it is your first time logging into the computer for the semester, please allow a few minutes as your profile is created. This will only happen once per semester.
Select Laptop if you would like to use your own laptop (or other device with an HDMI output). Open the little door next to the touchscreen controller to find the HDMI cable. Plug the cable into your laptop for both video and audio.
Select Bluray if you would like to play a Blu-Ray, DVD or CD. The player is located in the lectern below. You can use the onscreen display to control the player.
Select Document Camera if you would like to use the included camera located on the lectern shelf.
You can use the document camera to project papers, books or any object you wish to the projection screen. To begin, make sure that the camera is powered on.
At the base of the camera you will find the power button along with zoom and focus buttons. You can also adjust the camera arm in any position you like.
The camera also includes a light built into the camera for low light situations. Use the switch located on the camera head to switch the light on and off.
AUDIO CONTROL
On the right side of the screen you will find the main Volume control. Slide the blue dot up and down to adjust the volume of whatever volume you may be displaying.
You can click the small speaker icon under this slider if you would like to mute the audio completely. Press it again to unmute.
CAMERA CONTROLS
This room is outfitted with two cameras and numerous microphones for video conferencing/streaming. The cameras are controllable through the touchscreen controller and feed into the lectern computer for use with whichever conferencing/streaming software you desire (Teams/Zoom/Panopto/etc).
In the bottom left corner is the Camera Controls button. Press this button to open the camera controls.
On the camera control page, to the right you will see the camera select buttons. Cam 1 and Cam 2 will select either the instructor camera or the audience camera.
In the middle you will find controls that will allow you to move the camera to any position you may need for your class. Press the arrow button to pan or tilt the camera. You can also use the + or - buttons to zoom in and out. Next to the camera controls you will see three numbered buttons. These are preselected camera positions that you can use to quickly get the camera angles needed for a class. Each camera has their own presets.
Video Conferencing/Streaming
As stated above, the room cameras feed into the lectern PC (along with audio from the microphones) for use with video conferencing and streaming software. We will now go over the basics of conferencing software settings to take advantage of this equipment.
Teams
In Teams, open the settings page by clicking on the three dots in the upper left hand corner of the Teams window. This is right next to your profile picture.
In the drop down menu, select the Settings option.
In the following menu, select devices. This is where you can adjust the audio and video inputs of your Teams meetings.
The device page will be broken into two main sections: Audio and Video.
In the Audio section you will see a setting for Speaker listed first. This should be set to ExtronScalerD. This should be the same as the main computer audio output.
Below that are the settings for Microphone. This should be set to Echo Cancelling Speakerphone. When this is selected you will now receive audio from any of the room microphones (lectern mic, handheld mics and lavaliers). You must use one of these microphones in order to talk to any participants speaking remotely.
From this menu you can also click the Make a test call button to test your audio settings before you start a meeting.
In the Video settings section you will see a large preview of your camera feed. Below that is your camera select option. There should only be one option available, a camera named AV Bridge 2x1. This camera input includes both the Audience and Lectern cameras installed in the classroom. To change between cameras, use the Cameras option on the touchscreen controller.
Zoom
You can access your Zoom settings by opening the small arrow in the lower left hand corner of the taskbar. This will open a new menu. Click on the small Zoom icon to open the settings window.
Select the Video & effects option from the menu on the right.
Again, make sure that you have AV Bridge 2x1 selected as your camera. This will make sure that you have both the lectern and audience cameras selected for your meeting. While in this menu, it's also a good idea to make sure that you have HD video turned on as well. Zoom does not turn this option on by default. You should also turn on Maintain original ratio so that your online audience gets a nice widescreen image from the cameras. To change between the two cameras (Lectern and Audience) use the touchscreen controller on the lectern.
Once you have the video options taken care of, select Audio from the left hand menu.
This will open the Zoom audio preferences. Make sure that you have ExtronScalerD selected for your Speaker option (this should always be the same as the main computer audio output). You can click the Test speaker button if you want to double check that audio is playing in the room.
Now make sure that you have Echo Cancelling Speakerphone selected for your Microphone. Click the Test microphone button to make sure that your microphones are working. This will record a little bit of audio and play it back for you. Use one of the classroom microphones, either the lectern mic, a handheld or a lavalier mic.
MICROPHONE CONTROLS
This lecture hall is outfitted with a lectern microphone, four wireless handheld microphones and connections for up to six tabletop microphones (for guest panel discussions).
If you would like to use the lectern microphone, first make sure that it is powered on. There is a small power button located at the base of the microphone. You will see a small green LED light up if the microphone is powered on. If you do not want to use this mic, feel free to turn it off.
If you would like to use the wireless microphones or the tabletop microphones, please coordinate in advance with the IT Media Services department.
On the left side of the screen (above the Camera Controls button) are the microphone controls. To access these options press the Audio button.
This will open a small audio mixer to adjust the volume of the microphones. The lectern mic is the first option. Use the slider to turn the volume up or down.
Press the small microphone icon at the bottom of each slider to mute or unmute a microphone
. Press the arrow button to access a second page of volume sliders. These are the wireless microphone volume sliders.
When you are finished, please use the power button in the lower right corner.
When you press this button a screen will pop-up asking if you are sure you want to shut down the system. If you are, press the Power Down option. This will shut down the displays and reset the room for the next class.
If you need help with any audio or video equipment, please call IT MEDIA SERVICES 312-369-7550.
