A-CHAIN ALIGNMENT
The A-chain is the part of the sound system that covers the film path, solar cell,
optical preamplifier, slit loss equalizer and Dolby processing circuit.
The CP45 does not contain a magnetic A-chain but has facilities for switching
external magnetic preamplifiers into the B-chain via the Aux inputs. These inputs
may also be used for connecting digital film sound processors such as the Dolby
Model DA20.
