SECTION 4

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 noise reduction circuit.

The CP65 does not contain a magnetic A-chain but has facilities for switching external
magnetic preamplifiers into the B-chain. An overview of external magnetic A-chain adjustments
is given at the end of this section.
