SETTING UP MULTI-MEDIA
PROJECTION EQUIPMENT

Slide-cassette and filmstrip-cassette programs are audio-visual presentations that show a series of still pictures. They change in a certain order to go along with an audio cassette tape. As the narrative on the tape progresses, the visuals go from picture to picture at a pace determined by the tape. Usually, this is controlled by an inaudible tone on the tape.

The visuals may also be changed manually. The viewer hears a loud, audible tone and pushes a button to advance the next picture.

SOFTWARE CLASSIFICATION

Any LRC software package that is marked "SLCT" includes a tray of 35mm slides and an audio cassette. The audio cassette provides signals to change the slides.

A special type of cassette player is hooked up to a Kodak Carousel slide projector. As the cassette tape progresses, the slides change automatically. The pictures may be viewed on a large screen by a large audience.

When only a small number of people view a slide-cassette program, a Kodak Caramate projector can be used. A Caramate is a self-contained unit which includes a slide projector, an audio cassette player, and a built-in screen.

Do not confuse the "SLCT" software with the software labeled "FSCT." FSCT materials are played back on a Dukane filmstrip projector. Like the slide-cassette program, the filmstrip-cassette software includes pictures which are advanced by an audio cassette tape. An audio cassette player is normally built into the filmstrip projector. Both desk-top and large-room units are available.

Instead of a tray of individual slides, the filmstrip-cassette program includes a number of still pictures which are joined together into a single, compact strip of film. The filmstrips are each stored inside a small, plastic, cylinder-shaped case. Several cases of filmstrips, and the tapes that go with them, may be stored in a single box.

SETTING UP SLCT AND FSCT PROGRAMS

You should pay attention to how a program is organized. Most programs have identical narration on both sides of the audio cassette. One side automatically advances the visuals, using an inaudible tone. The other side contains an audible tone which signals the listener to manually advance the picture. Therefore, if you want the program to advance automatically be sure to use only the side of the tape which is marked AUTOMATIC or INAUDIBLE.

Before starting the program, be sure that the proper side of the cassette is facing you in the machine. Then, press the cassette unit REWIND button and allow all of the tape to wind onto one side of the cassette.

Set the tray of slides or filmstrip at the point where the program begins. Normally, a tray of slides is set for slide no. "O;" the point where a filmstrip starts is usually indicated by instructions on the filmstrip itself.

To repeat, whenever an audio cassette has both an AUTOMATIC or INAUDIBLE side and a MANUAL or AUDIBLE side, play the AUTOMATIC or INAUDIBLE side to achieve automatic visual advance.

However, there are some programs which have both their audible and inaudible tones on the same side of the cassette. With the proper equipment, the visuals advance automatically, but an audible tone allows the option of manual advance. This frees the other side of the cassette for other uses.

The second side may contain additional narrative for the same slides or filmstrip. It may provide the audio for a second program. It may be a separate audio-only program, not directly connected to the visuals. It may also be left completely blank.

As you can see, you have to look carefully at each program to avoid confusion. It is good practice to conduct a trial run of a program, paying attention to how the audio and visual media are organized. It is also a good idea to study the manual for the particular equipment that you will be using.
