1949 RECORDING EQUIPMENT 241 Disk reproducers are available which provide 33 Vs and 78revolution-per-minute speed operation, both with a flutter content of less than 0.1 per cent. One motor is used for both speeds, the change in speed beng accomplished by reversing the direction of rotation of the motor and translating this reversal into a speed change by means of specially designed overriding clutches. Two types of reproducers are available. Either can be used for both vertical and lateral reproduction but one is slightly more suitable for vertical while the other favors lateral reproduction. The Westrex re-recording mixer consoles are made on the buildingblock plan in self-contained sections of four positions each. The first section includes the monitoring and intercommunication facilities. Additional sections may be added to increase the number of input channels as required. The unit shown in Fig. 3 is a two-section console with a capacity of eight input channels. More than 70 channels of these new equipments have already been installed in studios throughout the world. To achieve continuing good results it is essential that these studios keep up to date on progress in recording techniques and equipment developments. To assist in achieving the desired results Westrex has built up an organization of trained recording personnel located in London, Paris, Bombay, Shanghai, and Buenos Aires. This service program has already shown worth-while results in maintaining recording standards, and should assist the foreign studios to keep abreast of developments in Hollywood and to bring worth-while developments from abroad to the attention of Hollywood, to the benefit of the industry as a whole.
