The Dolby Cinema Processor is the central element of the theatre sound system.
The projector, the Dolby Processor, the power amplifiers and the loudspeakers,
as well as the auditorium itself, must be considered when aligning the system
for optimum performance.
The system alignment procedure is divided into two parts—the A-chain
alignment which covers the projector, optical preamplifier, and Dolby noise
reduction adjustments—and the B-chain alignment which covers the portions
of the system from the room equalization circuits to the CP45 fader through to
the loudspeakers.
The alignment instructions in this Manual are presented in three columns. The
first column, Action, contains a drawing of the item to be adjusted and a
caption containing a brief description of the action to be taken. The second
column, Indication, contains a visual indication of the desired results, where
applicable. The third column, Notes, contains information which amplifies
and supplements the other two columns.
If you are familiar with alignment of other Dolby Cinema Processors you need
to follow only the information in the first two columns. If you are unfamiliar
with the equipment or face special situations that require complete information
you should consult the Notes column.
CAUTION
This Installation Manual is for use by qualified
personnel only. To avoid electric shock do
not perform any servicing other than that
contained in the Users' Manual unless you
are qualified to do so.
