The CLC is one of Grainger Halls most unique classroom designs. 2290 is the smaller portion of the overall room, and 2294 is a larger portion of the overall room. When the rooms are combined, they are sometimes referred to as 229X. This split is achieved with a divider wall and is accounted for in the programming of the AV system. Besides the ability to split the room, 2294 currently contains laptops for anyone to use should they wish to, and rather than a traditional single projection screen for all of the class to look at, due to the layout of the room, there are wall or stand mounted 55" monitors beside each table. There is one display per table, and in fact each individual display is paired with one table. Every table has an HDMI cable present that can be used for someone at that table to share content to the whole room, or to just their paired monitor, depending on what the instructor wants. Because of these factors, the rooms AV touch panel has some very distinct features that we'll get into below. 

The CLC has two podiums, one in 2290, and the other in 2294, and each one has an AV touch panel on top of it. When the rooms are combined (229X) the touch panels will both work for controlling the AV system in the same way and will mirror each other. When the room is divided, meaning the wall is up, the AV system will reflect this change by preventing someone in 2290 from altering the AV system in 2294, and vice versa.

The room can also be used for basic audio+shared content only web-conferencing, or recording via Zoom, only on the Podium Computer. Neither side of the room has a camera, but the wireless microphones in both halves of the rooms can be used for communication and recording via Zoom. 

When the system is off, the touch panel will display a "Press Here to Begin" screen. As with the rest of our classrooms, we do not use any passcodes or keys. When you touch the "Press Here to Begin" button the system will begin to turn on, and after the warm up period of 10 to 20 seconds, you will be ready to make an input selection.

Once you have turned the system on by tapping the "Touch Here to Begin" button, and the system has warmed up, you will see this input selection screen:

Inputs

At this point, you have the capability to project video and audio information from a selection of devices. These include:

	The Podium Laptop source button allows you to connect a laptop or other mobile device to the AV system via an HDMI connection present at the podium. Simply plug the cable into your device, and select the Podium Laptop button.
	The Podium PC is a computer that is permanently in the room. Its monitor is on the podium, and you'll find a keyboard and mouse on the podium to use with it. You can sign into the Podium Computer either with your Grainger Credentials if you have them, or with your NetID@wisc.edu for the username, and your NetID password.
	The Document Camera allows a user to project non-digital content onto the projector screen. Lift the Document Camera to turn it on, then select this button to project it. This device does not share any kind of audio.
	The Table Breakout Mode button will set every individual monitor to display the content from its paired table's HDMI connection. If nobody is connected to the HDMI cable at their table, their display will show a message asking them to connect. Once a user plugs the HDMI cable into their laptop, their laptops content will appear on just their paired monitor. This is best used for small group work and collaboration.
	The Table Input button will bring up a map of the room, restricted based on if you are using only one side of the room, 2290 or 2294, or both of the rooms combined. This map will show the tables, based on their real world positions, as well as with their numbers. When you select a table, whatever is connected to the HDMI cable at that individual table, will be projected throughout the room.

There is also a "Video Mute" button. This button will temporarily blank the video feed that is going to the projection system. Press it once to activate it, and then press it again to turn it off once you're ready to display your content again.

Presentation Audio

Along the bottom of the Presentation page, you will see your volume controls. This will allow you to raise or lower the audio volume coming from your selected input. To increase the volume, press the volume up button on the right side. To decrease the volume, press the volume down button on the left side. The audio mute button is just to the left of the volume down button.

Audio Page:

This page specifically controls the volume levels for the wireless microphones in the rooms, as well as some basic controls for web-conferencing and recording. The wireless mic volume slider works much the same as the presentation volume slider on the main presentation page. But we additionally have the options to Mute Incoming Audio, which will specifically mute anyone in a Zoom call, or any other kind of web-conferencing app, but will not mute the presentation audio coming from the podium computer. And Mute Outgoing Audio will mute the the microphones in Zoom, but will not mute their voice amplification in room.
