Once your film has been edited and the magnetic track applied by a specialist laboratory, you have the material for a masterpiece of your own making. The BOLEX SM8 projector provides unlimited scope for your imagination and ingenuity while its ease of operation will delight you. 1. A guide to recording When the green telltale lamp is alight, this indicates that the projector is connected to the mains and that the sound head is in playback position. The recording relay is engaged when the record player plug is introduced into the socket 19 of the projector. On pressing the two red keyboard switches simultaneously, the red telltale lamp comes on and the projector is ready to record. To return to playback position, presse the centre green switch: the relay is disengaged and the red telltale lamp goes off. When using the microphone, continuous pressure on the microphone switches governs recording and superimposition by remote control. Note: To safeguard against accidental erasure, the recording relay does not engage unless a plug has been introduced into the projector socket 19. If, by mistake, the two red switches are pressed simultaneously, the recorded sound will be diminished during this time, when the projector is running. 17 · Recording involves the total erasure of a previous recording, except in the case of superimposition (see page 21). · As soon as the red telltale lamp goes on - in other words, at the beginning of recording - the built-in or external loudspeaker operates at very low strength, making it possible to monitor the passage being recorded and follow the course of the recording very easily. In order to concentrate the operator's attention on sound and picture synchronization, only one socket is provided for the record-player or microphone input. Thus the musical background is recorded first and speech is superimposed during a second passage of the film. The microphone has two switches and two functions: · Recording (with complete erasure of a previous recording), operated by simultaneously pressing the red and black switches. · Superimposition (see following page), operated by press·ing red switch alone. In both cases, this remote control replaces the use of the projector keyboard switches. As soon as the microphone switches are released, the red telltale lamp goes out and the sound head returns to playback position. · By way of a triai run, without starting the projector, press the two microphone switches and speak at a normal level. In the loudest passages, the indicator needle should not appreciably exceed the black segment on the dial or distortion will result during playback. · Position the film and return the counter to zero (see preceding page). · Run the projector in reverse for a few moments until the figures 997 (or lower), appear in the counter. · Move the control switch to M: the projector is running. · Watch the counter. [. . . ] Lubrication We recommend regular lubrication: one or two drops of fine oil should be applied to the lubrication points shown on page 9 after every 20 hours of actual operation. 2. Replacing and centering the projection lamp Remove the lamp-house cover by loosening the screw p. When inserting the new lamp (12 V/100 W), avoid touching it with the fingers which damages the quartz. If this happens accidentally, clean the lamp at once with cotton wool dipped in alcohol. [. . . ]
