new EASTMAN Digital Sound Recording Film 2374 (Estar base) lets you take
advantage of the new Cinema Digital Sound technology.
Now, the impact of today's digital technology
to the movie theatre with astonishing true-to-life sound.
The CINEMA DIGITAL SOUND system consists of the Model
Processor and the Model CDR-7035 Reader.
The CDR-7035 Cinema Digital Reader is
on the projector, or penthouse of the projector, and reads the digitized
sound track that has been written on the film. The Reader can perform
and decoding functions on both 35mm and 70mm motion picture film sizes.
The signal output of the Reader is directed to the CDP-1OOO Cinema
Processor for processing and conversion to analog signals to drive
the auditorium speakers.
Error correction circuits in the CDP-1OOO Processor
adjust for any imperfect travel of the film, imperfections
on the film sound track and film splices. The resulting sound is free of
hiss, pop, clicks, and other extraneous noise. Only the sound that was
recorded and mixed by the film maker in the sound studio is delivered to
the auditorium sound system.
The translated (digital-to-analog) output of the
is directed to the house amplifiers and speakers for the enjoyment of
most critical listener - the audience.
