I understand that the troubles were largely mechanical, since an attempt was made to use almost the same star used in the smaller intermittent movement, and the heavier film naturally produced greater wear and gave quite a "slap." If the Grandeur film were run at 24 frames per second, the linear velocity of the film would be approximately 112 feet per second, which, as explained above, would improve the high frequency response. Even at 20 frames per second the velocity is slightly higher than that of the 35-mm. film, and the high frequencies are somewhat improved. Even greater improvement is possible, however, since it is possible to decrease the "thickness" of the light beam and improve the highs and yet get more output than is possible with the standard .080 of an inch track. One problem has arisen with the wide-scope film that has not been serious with the standard film, and this is the problem of sound source illusion on the stage. In a number of demonstrations o_f the Grandeur film, _ an operator monitored the output of the amplifier and shifted the output to different speakers on the stage as the character moved about. A number of suggested methods have been advocated, and this problem like others will be solved satisfactorily. With these improvements in recording and reproduction, and with the equipment that is now available or will be available in the immediate future, I believe that the greatest improvements in the future will be in the theatres themselves — taking the form of careful, scientific acoustical correction in the older houses, and careful design in the new ones. Many improvements must be made in the recording end and in the selection of suitable subject matter, and careful consideration must be given the psychological problems involved. LOW FREQUENCY CONTROL DEVICE A DEVICE called a frequency suppressor by the manufacturer, has been developed by the Gates Radio & Supply Company of Quincv, 111. It is a frequency control designed especially for installations with dynamic cone speakers. The control is variable, it is said, allowing full bass reproduction, slight or total suppression of the low frequencies. Mellaphone in Europe ROCHESTER, N.
