Rooms 101 and 102 of Warren Weaver Hall are mirror images of one another and have identical A/V set ups. Each has a cabinet with a Windows computer and laptop connection, handheld and lapel wireless microphones and audio equipment, all connected to the projectors and speakers that serve each room. Switching from the PC to a laptop occurs automatically.with a few seconds delay. . Please review the instructions below.
Each room has a cabinet, which acts as both a podium and media rack. In general, the fronts of the cabinets are left open so instructors can access the in-room PCs, its DVD drives, and audio controls. Wireless microphones can be found in the supply drawers. The backs of the cabinets should remain locked. Please do not alter the cabling within the cabinets, as this could potentially disable some equipment, inconveniencing other users and the staff who would have to make any replairs.
The keyboard and mouse are in a tray at the top of the cabinet, just below the work surface, which slides in and out of the podium. There is also a light on top of the podium, with a brightness control knob at its base, to illuminate the work surface if desired.
Each contains the following components:
- A PC running Windows 7, and VGA and audio cables for a laptop.
- A switch that controls which input device is displayed on both the monitor and the projector.
- An audio amplifier that goes to the speakers in the room.
- Mixer Audio Controls: These allow you to control the volume for a particular piece of equipment.
- A storage drawer that contains some extra cables and the wireless microphones, as well as spare batteries for the microphones.
- MainSwitch: This main switch will turn off everything in the cabinet, so it MUST REMAIN ON AT ALL TIMES.
Using the Projectors
To power on and off the projector, use the switch on the wall next to the switch for raising and lowering the projectrion screen. Always select the COMP button for the computer. The projectors need a few minutes to cool down and warm up. PLEASE TURN THE PROJECTOR OFF AFTER EACH SESSION.
The switch auto-detects the input of a laptop. Otherwise it will display the output from the PC. Once the laptop cable (extending out of the top of the cabinet)is connected to a laptop, the input device should automatically change.
