The room is controlled with a 4-inch Crestron touchpanel. With the press of a button the projector turns on, the screen drops, audio ramps to the appropriate volume, and software on the dedicated PC is displayed on the projection screen.

In videoconferencing mode, the instructor can connect to any Level 2or Level 3 classroom on the Cal U campus or to any IP-based outside videoconferencing system. Four wireless handheld microphones and one wireless lavalier (lapel) microphone provide audio transmission for the presenter(s), who can send any two sources to the far-end participant simultaneously. As many as five additional classrooms can be connected through the videoconference.

A 15-inch Crestron touchpanel controls basic functions and all aspects of the audio-visual system, including videoconference-call dialing, source routing, volume and lighting.

• Each student seat has a push-to-talk microphone and an individual 4-inch Crestron touchpanel with keypad. Each student enters his or her name at the start of class; it appears on an LED board so the professor can identify each member of the class.
• When a student wishes to ask a question, he or she presses a button to activate the microphone. The videoconferencing camera zooms in on the student asking the question; when the button is released, the camera zooms back to full classroom view. 
• Touchpanels allow the instructor to poll students anonymously. Students use the keypad to answer multiple-choice questions, then view the real-time results on the touchpanel.

Presentations in Level 3 rooms can be recorded with a MediaSite recording system and then uploaded to a server, so students can log in and stream the sessions from anywhere in the world.
