The Junior DeForest Phonofilm and Phonodisc is a typical DeForest achievement for theatres of 750 seats or less. This gives the smaller theatre an opportunity to have the best sound in town for $4,975 for all production either on film or disc. The units are leased separately also; the Phonofilm at $3,995 and the Phonodisc at $2,745. Any one of the six can be procured on the most liberal time payments that have ever been offered exhibitors. A moderate down payment, with the balance in sixty weekly payments, will secuie any of the devices. Details of the plan, according to which equipment you desire, can be secured from any authorized distributor for General Talking Pictures Corporation or by communicating directly with us. PHONOFILM PHONOFILM, as the name implies, is sound-on-film equipment. It is the invention of Dr. Lee DeForest, who turned his attention to talking motion pictures in 1918, to develop a new use for his audion tube. His audion tube is the only means of controlled sound amplifica- tion and is an essential part of all talking picture equipment, as well as radios and long-distance telephone lines. In 1919 Phonofilm came into being, and the present Phonofilm reproducing device is the result of a decade of constant improving and simplifying. Unhampered by any fear of patent infringements, for General Talking Pictures Corporation owns the only sound-on-film patents which are now in the Federal Courts for adjudication, Dr. Lee DeForest and a corpse of engineers were free to make any changes, simplifications and improvements which were indicated by actual operation of DeForest Phonofilm reproducing devices in American and foreign theatres since 1923. Six years of actual theatre experience stands behind the perfection which has now been attained by Phono- film. "The show must go on,” the one imperative rule of the theatre business was adopted as the slogan of the Phonofilm engineers. Every change that was made dictated by an inflexible order that the quality of reproduction must not be impaired, and that it must add surety of continuous performance under any circumstances. The result is that only the same ordinary care that is bestowed upon a projecting machine and a radio is necessary to keep Phonofilm running efficiently week in and week out. Exciting lights do burn out. Phonofilm has a second one that can be snapped into place and automatically lighted in a flash of a second. It is double channel throughout. An exclusive device called "the spin wheel” insures the smooth running of the sound track past the photo electric cell which explains the constant efficiency which is noted only in Phonofilm projection. Numerous other features con- tribute to the smooth, continuous, efficient service given by Phonofilm
