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

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

For tighter budgets, the CP650SR comes equipped to process Dolby SR and A-type analog soundtracks only, while the most popular configuration, designated 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.

The 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.

Unique 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 exceptional 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 serial and Ethernet interface accommodate PC control and cinema network connectivity. 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 available in a variety of configurations to suit every projection requirement.
