Key Upgrades and Options

Cat. No. 735 Auditorium Assist Microphone

The Dolby Cat. No. 735 microphone, mounted permanently

and inconspicuously in the auditorium, works in conjunction

with the Auditorium Assist feature provided in all CP650s to

help you maintain consistently high performance from your

cinema’s sound system.

Once your room is initially

aligned, Auditorium Assist uses

the Cat. No. 735 to take meas-

urements of the frequency

response and level of each chan-

nel, plus the room’s ambient

noise floor, which are then stored within the CP650 as your

Auditorium Reference. Thereafter, whenever you run

Auditorium Assist, it takes the measurements again and

compares them to the Auditorium Reference, all in less than

90 seconds. You are alerted to any discrepancies to help you

diagnose and resolve faults that may have occurred in the

speakers or other system components.

Cat. No. 790 Dolby Digital Surround EX/Digital Input Card

The Cat. No. 790 card, which is standard in the CP650 and

CP650XO configurations, provides Dolby Digital Surround EX

decoding. It also provides four AES3 inputs that

accommodate up to eight channels of digital audio

(at 44.1 and 48 kHz) from sources such

as digital cinema servers,

disks, tape playback systems,

and satellite or cable links. The

CP650 converts the digital audio

to as many as six channels of analog

audio (up to eight channels with a Cat. No. 791 installed) for

playback through your sound system.

Cat. No. 778 Digital Input/Output Card (not shown)

For dubbing studios requiring digital input and output,

the Cat. No. 778 Digital Input/Output Card can substitute for

the Cat. No. 790 to provide four AES/EBU digital inputs and

up to five AES/EBU digital outputs.

(The Cat. No. 778 disables the CP650’s analog output.)

Cat. No. 791 Digital Crossover Card

Cat. No. 791 Digital Crossover

Card, which is standard in the

CP650XO, integrates two-

or three-way speaker crossovers

into the CP650 for your L, C, and R

screen speakers. It also provides outputs for full-range

Le and Re screen speakers.

All audio processing is in

the digital domain,

enabling extensive

settings and adjustments

via a PC software package

or built-in menus using the

front-panel main display.

As well as ensuring the

highest possible perform-

ance from your screen speakers, the Cat. No. 791 eliminates

the need for a stand-alone crossover unit.

(A Cat. No. 790 must be installed in the CP650 in order to

add the Cat. No. 791.)

The Dolby

CP650 is the only all-digital cinema processor

capable of playing back both digital and analog 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.

Four Configurations

The CP650’s most popular configuration, simply designated

CP650, processes Dolby SR and A-type analog, 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 analog 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.

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.

A built-in bypass power supply helps ensure that the show can

continue should a fault occur in the main CP650 power supply.

The Dolby CP650 is the best investment you can make in a cinema processor.
