Dolby Laboratories CP650 User Manual
The Dolby®CP650 is the only all-digital cinema processor
capable of playing back both digital and analogue Dolby
soundtrack formats. Its high quality, proven reliability,
unrivaled versatility, and ease of setup have earned it a
place in thousands of flagship cinemas worldwide. It can
also accommodate new technologies such as digital
cinema, ensuring a long and useful product life.
Five Configurations
The CP650’s most popular configuration, simply
designated CP650, processes Dolby SR and A-type
analogue, Dolby Digital, and Dolby Digital Surround EX
™
soundtracks. It also provides four AES3 inputs for digital
cinema audio. To these features, the top-of-the-line
CP650XO adds built-in crossovers for screen speakers,
eliminating the need for a stand-alone crossover unit.
For tighter budgets, the CP650SR comes equipped to
process Dolby SR and A-type analogue soundtracks only,
while the CP650D adds Dolby Digital decoding; neither of
these models includes Dolby Digital Surround EX decoding
or digital audio inputs. However, as your needs change and
new formats are introduced, you can upgrade any CP650
configuration with plug-in circuit cards and new software.
For digital cinema installations that do not require replay of
film sound tracks, the CP650DC provides digital audio
inputs for connection to a digital cinema server whilst
removing the additional cost of 35mm support.
Exceptional Features
Built-in installation tools (including a real-time analyzer
and the unique EQ Assist
™
system) significantly reduce
alignment time. In day-to-day operation, the Auditorium
Assist
™
feature can alert you to discrepancies from the
sound system’s initial calibration, signaling a fault such as
a speaker driver failure.
The CP650 is most efficiently installed and calibrated with
the help of a laptop PC running comprehensive setup
software (available in several languages). Calibration can
also be accomplished using the CP650’s front-panel
controls and main display. Software upgrades are
conveniently accomplished from a PC.
A built-in Ethernet interface makes it possible to control
and monitor the CP650 from a remote location – a head
office hundreds of miles away from the cinema, for
example.
The Dolby CP650 is the best investment you can make in a cinema processor.
