This is a short (but quite rare) document on operating the photophone (1929).
Provenance: Harold E. Sunde, with his initials in pen at top left front cover, and signed by him on final page. Sunde (1910-1990) was responsible for the explanation and demonstration of the RCA "Photophone" invention--one of the earliest simultaneous sound-on-film recorders and projectors, and introduced the machine to England and Russia, where true sound-on-film motion pictures were seen for the first time. He was also JHU APL, Sandia, Radiological Defense at Bureau of Ships, USAF). This document appears just a month or so before the showing of the first successful synchronized sound-on-film picture in England, A. Hitchcock's “Blackmail”. This a sound-on-film incunable. This means the pamphlet was printed within the first few years of the first "talking" (synchronized sound, or sound technologically coupled to image) motion picture. The first feature length film using sound throughout the length of the movie was The Jazz Singer, which was released in 1927 and used a sound-on-disc2 system of recording. That means that the audio portion of the film was recorded onto records, and then synchronized in playback with the film to match up the audio and video--this technology was obviously not the future.
The technology of sound-on-film would take the day, and in very short order, leading to four different systems, of which the Photophone was one. Photophone's share of the prospective studio users was pretty good: the earliest major producers/licensees included Walt Disney Productions (after 1932), RKO Radio Pictures, Republic Pictures, Warner Borthers, and Pathe.
" From the producer's standpoint, variable area film recording has one great advantage that places this system in a class far ahead of all others".
Content: following a general intro to the equipment, which is followed by four section, including the auditorium, the projection room, the power supply, and the power equipment. The auditorium notes interestingly describe what the operator of the photophone should pay attention to in the building, touching on the location of the speaker, but particular attention was made for the architectural properties of the auditorium and how they might affect sound quality. This is followed by the projection room comments, and then the power supply needs and the power equipment itself, the ending item being the “synchronous disk requirements”.
