| Almost every item of Westrex equipment involved in the 6-track stereophonic sound recording of "Oklahoma!" in the TODD-AO process was especially designed by Westrex. Two 6-channel stereophonic production recording systems were supplied which were used both on location and on the stages at MGM Studios. These systems consisted of mixer input facilities capable of accommodating six stereophonic microphone inputs, a 6-channel RA-1547 recorder and associated power supply equipment. Both of these systems were mounted in van type mobile units containing their own power supplies. A special stage at the Studios in Culver City was completely equipped to do the complex re-recording work necessary. This installation required a special console capable of accepting 96 separate input circuits. To reproduce the music, dialogue, and sound effects tracks associated with the re-recording operation, Westrex furnished 12 RA-1551 type six-track stereophonic reproducing machines. Two additional RA-1547 six-track stereophonic recording machines also were furnished for "Oklahoma!" recording. | More in 70mm reading: Todd-AO The Todd-AO Projector Showmen’s Trade Review, October 15, 1955: Oklahoma! in Todd-AO Todd-AO Magna Theatres Todd-AO Corporation Philips Collaborated On Projector Design Todd-AO Projection and Sound Six track recording equipment All-Purpose Sound Reproduction Rodgers & Hammerstein II Six track recording equipment Internet link: |
