The Dolby^® CP650 Digital Cinema Processor is the exhibition industry's preferred cinema processor worldwide. Continuing the long evolution of Dolby cinema sound, it is the only all-digital cinema processor for the playback of all Dolby soundtrack formats, combining advanced signal-processing technology, highest-quality components, and sophisticated manufacturing processes to provide the best sound and utmost reliability.

Thanks to built-in features such as Dolby Digital Surround EX™ decoding and four AES-3 digital inputs, the Dolby CP650 Digital Cinema Processor is the most cost-effective Dolby processor. Excellent reproduction of analog soundtracks is facilitated by fully digital implementations of Dolby A-type and Dolby SR decoding.

Thanks to the compact, cost-effective Dolby CP45 Cinema Processor, even the smallest of cinemas on the tightest of budgets can install a Dolby sound processor. This means that the audience can hear analog Dolby soundtracks as they were meant to be heard, and you can use the widely recognized Dolby logo to promote your commitment to a quality motion picture experience. 

At the heart of the CP45 is genuine Dolby processing for Dolby SR analog soundtracks, which are standard on all 35 mm release prints today, including those that also have digital tracks. With the CP45, any cinema can afford to play back Dolby SR soundtracks with outstanding clarity and fidelity. Dolby A-type noise reduction is also included for older prints.

The cost-effectiveness of the CP45 results in part from the use of integrated circuits developed in response to the wide demand for Dolby technologies. It also benefits from a simplified power-supply design, and a new approach to speaker EQ that features seven bands for each screen channel, plus tunable high- and low-frequency shelving controls. Selectable electronic crossovers for biamplifying the screen channels are also built in.  

With the addition of the Dolby DA20 Digital Film Sound Processor, the CP45 can be used to play back Dolby Digital soundtracks. However, cinemas intending to equip for Dolby Digital within a foreseeable timeframe should start with the more flexible Dolby CP650SR processor, which can be upgraded to Dolby Digital and Dolby Digital Surround EX simply by adding an upgrade kit.  

As with all Dolby sound processors, the purchase of a CP45 includes the unrivaled support of Dolby Laboratories. Hundreds of technicians worldwide have been trained by Dolby engineers in the installation and maintenance of Dolby equipment. Emergency technical assistance is available on call, as is backup from the most experienced distributor network in the industry. The CP45 is the only cinema processor in its price range backed by a decades-long history of making films sound better.

The Model CP65 is the fourth generation in the series of Dolby cinema processors that reaches back to the introduction of Dolby Stereo itself. In a familiar, easy-to-operate format, it provides a unique combination of flexibility, high performance, and cost-effectiveness. 

Two channels of Dolby SR are incorporated within the CP65 to take advantage of the higher quality soundtracks on Dolby Stereo SR prints without the cost and complexity of an external adapter. Dolby A-type noise reduction is provided in addition for conventional Dolby Stereo playback, so that the CP65 is equipped as standard to play all current 35 mm analog optical formats. 

Dolby Cat. No. 702 Digital Soundhead

The Dolby^® Cat. No. 702 Digital Soundhead is a penthouse-type reader that bolts directly to many current and older projectors, enabling playback of Dolby Digital and Dolby Digital Surround EX™ soundtracks.  

Designed for high performance and long-term durability, the Cat. No. 702 is a reference standard for Dolby Digital soundtrack reproduction. To read the Dolby Digital track on 35 mm Dolby Digital release prints, the Cat. No. 702 uses a newly designed, more efficient CCD board and lens, an LED level indicator and adjustment, an integral power supply that requires no AC connection, and the latest in LED technology. The resulting signal is fed to the cinema's Dolby Digital processor or decoder.  

To ensure smooth film motion, the Cat. No. 702 features an easily threaded Davis tight loop configuration with twin tension arms for superior film guidance.  

With benefits that include high sound quality, on-film soundtrack placement, and ease of print manufacture, Dolby Digital is the standard for multichannel sound around the world. The Cat. No. 702 soundhead facilitates upgrading cinema systems to take full advantage of Dolby Digital, including Dolby Digital Surround EX with its third, rear surround channel.

Dolby SA10 Surround Adapter

PDF File

The Dolby SA10 adapter upgrades any existing 5.1-channel digital cinema sound system to play back the three surround channels on digital prints prepared using the Dolby Digital Surround EX process.

With Dolby Digital Surround EX, a center surround channel is reproduced by the speaker array at the back of the theatre, while left and right surround is reproduced by the side arrays (see illustration). This configuration enables true 360-degree pans, more realistic front-to-back and back-to-front transitions, and ambient sound reproduction that is less affected by the width of the cinema.

In most cases, equipping an existing 5.1-channel digital installation for Dolby Digital Surround EX is simple and economical. All it usually requires is wiring the surround speakers into left, left back, right back, and right groups; providing additional surround amplification; and installing the SA10 in the booth between the existing cinema sound processor and the power amplifiers. Dolby Digital Surround EX playback may be selected manually by the projectionist, or automatically by means of a digital data flag that film producers can incorporate into the soundtracks of Dolby Digital Surround EX releases.

For each of the three surround channels, the SA10 provides seven-band equalizers operating in conjunction with tunable high- and low-frequency shelves to ensure smooth surround-speaker response to the international standard curve. Front-panel controls include a mode selector (5.1 or Dolby Digital Surround EX), signal-present channel indicators, and a backup power supply selector. Rear-panel connections make it possible to select the Dolby Digital Surround EX mode remotely with automation systems.

The Dolby DA20 makes it possible to decode and play back Dolby Digital soundtracks in cinemas equipped with analog cinema processors. Interface kits are available from Dolby Laboratories for the CP45, CP65, CP55, and CP200.

The DA20 is equipped for use with two projectors outfitted with either inboard Dolby Digital soundtrack readers or Dolby Laboratories' penthouse-style digital soundhead. Once installed, its operation is essentially transparent, requiring virtually no attention from the projectionist. There are no operating controls. LEDs indicate digital or analog operation, the modulation level of each channel on Dolby Digital soundtracks, signal presence at the unit's outputs, and which projector is in use.
