The minimum active space required is 7.5 meters by 7.5 meters by 3.5 meters high, or, 25 feet by 25 feet by 12 feet high. The major consideration in terms of space is the total avoidance of ambient light. The space should be painted a non-reflective black and no light source should exist, other than the one that emanates from monitors themselves. Also include a low bench seating four or five people. The entrance must be well insulated from light and sound. Most ideal is a double trap door with sound insulating material. (See floor plan and entrance diagrams.)

NOTE: The tech equipment except the monitors and speakers should be located outside the exhibition space in a small adjacent tech area.
The Vasulkas can provide all the equipment listed below, or share resources with the exhibitor. This will be reflected in both shipping and equipment budgets.
  15 or 18 matching video monitors 3 Pioneer Video Laser Disk Players, LD-V Series
3 program video laser disks NTSC, color
1 three channel synchronizer
3 stereo audio amplifiers (6 audio channels)
6 speakers (internal speakers of superior quality may be used)
6 speakers stands or wall mounts
15 video cables
3 pairs of stereo cables
4 speaker cables
22 power outlets
1 circular rug (optional)
NOTE: The laser disk synchronizer used by the Vasulkas is custom built and interfaces only with Pioneer Industrial Laser Disk Players (2200 to 8000 Series). It is not interchangeable with laser disk players from other manufacturers, such as Sony and Phillips, which require a commercially available synchronizing.
The fifteen (or eighteen) monitors must be matching in size and manufacture. They are placed on the floor in a circle facing inward without spacing in between, tilted about 30 degrees upwards. Some monitor models are designed to make this easy; with others, wedges must be built to be put under the monitors to tilt them upwards from the floor. These wedges must be custom-made (one for each) to fit the size and shape of the monitors.

Place a circular rug (provided along with the other installation equipment) in the middle of the room. The rug provides a convenient way to establish a center around which the monitors can be placed in an approximate circle. An alternate method is to draw an erasable circle on the floor.
   First connect the players to the monitors (see drawings). Channel one connects to the first on the line, skips the next two, connecting to the fourth, seventh, etc. Channel two connects to the second, fifth, eight monitors, etc. Channel three connects to the third, sixth, ninth, etc., monitors in the circle. If the monitor speakers are of very good quality, the audio can be chained the same way as the video (six discreet audio channels), so the sound emanates from each monitor in equal intensity.
   After verifying that all audio and video cabling is working, lift the front of each monitor one-by-one about 30 degrees up to place the pre-fabricated wedges underneath. Now push the monitors toward the middle, an equal distance from the edge of the rug, so that the front edges of the monitors touch. Once the circle is perfect, all the cables should be tucked under the monitors and tied down. Finally, remove the rug or erase the drawn circle.

Connect the two stereo cables from each player to the three amplifiers, and the six speaker cables to the speakers. The speakers should be hung on the walls at equal distances.

Treble should be normal and bass at maximum. All 75 ohm terminators located on the back of the monitors must be switched to open, except for the last monitor on each chain. Contrast should be high and brightness below middle. The basic rule here is to set up the proper deep color black as a reference to the maximum contrast and brightness. With that, the other components (hue, color saturation) can be assigned. The persons installing the environment must use their esthetic judgment as to the proper monitor settings for maximum visual impact.

Power up the monitors, disk players, and synchronizer. Wait a short while to verify that the installation is starting synchronously. If not, turn power off and on again for the players and synchronizer. If problem persists, notify Steina by phone, fax, or e-mail.

Turn power off the monitors, disk players and synchronizer.

The monitor screens need to be cleaned with a soft cloth at least once a week.
