Dolby Laboratories CP650 Key Upgrades and Options

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

measurements of the frequency

response and level of each

channel, 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,

CP650DC, and CP650XO configurations, provides

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.

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 analogue 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

performance 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.)
