(KA tape machines, similar to those used in 1 programming satellites for space probes. Each lone of these machines sends 14 channels of sound into the voice of the system, a series ct 56 speakers carefully-positioned under tahks and in other unseen locations. Sound of Events Given Depth and Presence The speakers were engineered and built by James B. Lansing Sound, Inc., Los Angeles. Unlike ordinary stereophonic sound which, good though it is, is limited in feeling and lepth of movement, the Stereo-Rama Fourteen process reproduced the sound of an event in perfect depth and presence.

In addition to research l\)r the setting, and li^ many problems inherent in development of 111 sound system, Mr. Stuart and his staff spent (more than two years digging into the history !)f the Continental Congress and the lives of ts members. Thousands of original documents vere examined to uncover the backgrounds and opinions of the 56 delegates assembled in InIcpendence Hall.

Among the large Stereo<ama Fourteen cast are such illustrious radio, ilm and stage voices as those of Jay Jostyn. Jrainarcd Duffield, David Bond, Marvin Miter, Nestor Paiva. and Ted de Corsia.

Again they were wrong, for on July 4, 1967, first anniversary of the opening of Independence Hall/ West Coast. 450,000 visitors had come under the spell of the presentation, and the project clearly has settled in for a run of at least several hundred years. • * * * Engineered for Fidelity Stereo-Rama Fourteen"s mechanism is a pair of .Anipex AG-300-14 solid state professional audio recorders. This is equipment from the 300-scries modified to handle one-inch wide. 1.5 mil magnetic tape and to provide 14 channels. The machines run at cither T'/i or 15 inches per second. Ten of the channels carrv dialogue, three are used for special sound effects, and the final track controls the room lights, candles, and audio special effects switching from speaker to speaker. The Ampex equipment is rack-mounted in a spacious projection room on the building's second floor ... in space which in the original building in Philadelphia was rarely used until the beginning of the nineteenth century, when it housed a museum complete with stuffed birds. Set Up for Duplicating and Standby Use To provide duplicating and standby capacity, one unit is a record reproduce machine, and the other is a reproducer only. The recorders are used on alternate days, leaving the extra unit for standby. The combination allows operators to make their own play copies of tapes CrdNriNLtD 0\ IMF FOLLOWING I'XGE 46) .\bove: liiiilinj nj SinmiUi i\ .Sui////*! >/if/e projectors used to depict historic moments in historij virteed htj audiences at start of tours leithin the modern Little Theater (below). 45
