This audio tape has the recorded narration and music on one track with inaudible cue signals ¥ ^^f u Making fina! citijuiiiiieiits on the mobile projection counter is Hal Guzofsky, president of Audiovisual Consultants and Colorado Visual Aids. on the other track. The cues advance the punch tape programmer a step at a time in perfect synchronization with the audio script. Whenever the instructor might wish to interrupt the program for comment or discussion, he merely stops the audio tape, and then can continue the automated program by starting it again. With the manual override feature, he can depart from the prepared program, reverse slides to a previous image to answer a question or assist in a discussion, return to the point where he departed from the program and then continue by starting the tape again. Program versatility Some programs are best used where the instructor presents the script "live" rather than pre-recorded on tape. However there may be complex cues to the multi-media program which require several slide changes simultaneously, or perhaps turning off two slide projectors while starting the 16mm film all at die same time etc. The program complete with these complex cues can be fully programmed and automated on the punch tape. The instructor tells the story according to the script and merely presses the single step-advance button on the control panel to advance the punch tape to the next event according to the script. The event counter shows the instructor exactly which event the program is at, and he can be certain he is at the correct point in the script. The instructor can make his presentation at his own pace, he can ad-lib, vary the presentation, stop for questions and discussion . . . and whenever he is ready to return to the script, he can call for the next event merely by pressing the step advance button. The system is not only flexible, it is completely mobile, and when more permanent quarters are decided upon for the training division, the entire system can be easily re-located. In fact, several rooms can be pre-wired to accept this audio-visual system. The custom remote control consolette and the entire equipment package on the custom projection counter can be taken to any pre-wired room and pluggedin to make it a complete multimedia facility in minutes. 30 BUSINESS SCREEN
