OPERATION OF SOUND EQUIPMENT 595
an occasional word or sentence of the dialogue. Where either condition obtains, discriminating theatre patrons (and their number is rapidly increasing) either lose their taste for motion pictures or else seek some place of entertainment where sound projection is better managed. If there be none such available, the interval between their theatre visits lengthens very noticeably and the theatre box office suffers.
(14) Such conditions are not ordinarily due to any fault of the projectionist. The fault rests squarely on the shoulders of the management or the manager. It is due entirely to the fact that either he has not installed any system of volume control, or if he has one it fails in its purpose.
The monitor horn unfortunately cannot be made to supply a reliable guide to auditorium sound volume. It serves merely to assure that the sound equipment is operating and for the receipt of sound cues.
(15) In all except a very few theatres the only practical system of volume control under all conditions is by means of an "observer," and a bell and buzzer located preferably on the front projection room wall, between the motion picture projectors.
This bell or buzzer is controlled by a bell button located in some inconspicuous place in the rear of the auditorium, not too near an entrance. On the back of one of the aisle seats in the rear row is usually the best location.
This bell is for use by the observer, who by a prearranged signal code is enabled to advise the projectionist as to sound level.
Provided the right person is selected for the observer, and further provided he attends solely and continuously to that duty, the results will be very greatly improved and the cost of the observer unquestionably will be much more than covered by retention of patronage and new patronage attracted by excellence of the entertainment.
(16) This is, however, something that unfortunately cannot be directly checked. It is a matter upon which the manager must use common sense and his reasoning powers. His showmanship must be his guide.
