Abstract: A new dubbing (re-recording) and scoring (music recording) building recently completed on the Republic lot consists of a recording stage, scoring monitor room, machine room, projection booth, power room, maintenance room, and a recording truck testing platform. The recording equipment consists essentially of two complete RCA high-fidelity recording channels, together with their associated equipment of film recorders, film phonographs, amplifier racks, power rectifiers, dubbing and scoring consoles, “acetate” recorder and projection equipment. The stage is of the live-end-dead-end type, and has dimensions which conform to the recommended 1:2:3 ratio. The live-end is provided with permanent side wall and ceiling reflecting panels which increase the reverberation and diffusion of sound. The remainder of the stage is treated with 4-inch rockwool battens, placed between the studs and retained in place by a dual muslin covering. The measured reverberation characteristic of the stage, fulfilling recommended requirements, is between 0.95 and 1.00 second for the frequency band of 540 to 7000 cps. The stage is equipped also with an eight-position mixer console so that dubbing may be monitored in a room having approximate theater sound characteristics.
