Equipment at the instructor's station

On the desktop:

• A remote control, mounted on the extreme left of the desktop. This remote control points at and controls the 3M projector hanging from the ceiling. This projector displays images from the computer, the videocassette recorder (VCR) and the laserdisc player. It does not control sound; for information on getting sound to play, see the section entitled "Getting sound to play," below.
• A Power Macintosh 7600 computer and AppleVision monitor are just to the right of the remote.
• A Panasonic television monitor and a Panasonic multistandard VCR are located to the extreme right of the desk. This monitor displays images from both the VCR and laserdisc player.

Under the desk:

• The top component is a Pioneer laserdisc player.
• The middle component is a Marantz amplifier. This box is what allows sound to go from the computer, VCR or laserdisc player through the speakers mounted on the wall to either side of the central projection screen.
• The bottom component is a tuner which allows cable TV to be fed to the monitor and the projector.

On the wall next to the instructor station:

There are five light switches located here.

• The switch to the extreme left controls the central projection screen. To bring the screen down, press this switch down. To raise the screen, press this switch up.
• The second switch from the left turns on a spotlight above the instructor station, to help you see better at the instructor station if you have the rest of the room dark.
• The last three switches control the three banks of overhead lights. Duplicates of these switches are also located by the door.

In addition, the Mellon Electronic Classroom contains a regular overhead transparency projector. If you wish to use it, feel free to wheel it to the center of the room and plug it in to the electrical outlets in the floor.

Finally, there is a slide projector at the rear of the room, just above the computer labeled "Language Lab #9". The power and fan switch is located on the left side of the slide projector as you face it, so you may need to turn it towards you to turn it on and off. The slide projector is intended for use with the smaller screen at the front of the room, located to the left of the main projection screen. This screen may be raised and lowered manually using the attached string.

Showing images and video

Image projection from the computer, VCR and laserdisc player is controlled from the remote control located on the extreme left side of the desk at the instructor station.
