Product Description

The Dolby Digital Cinema Processor CP750 provides easy-to-operate audio control in digital cinema environments. It supports innovative Dolby Surround 7.1 premium surround sound and integrates seamlessly with existing technologies.

Versatile Audio Processing for Digital Cinema

Designed specifically for digital cinemas, the Dolby® Digital Cinema Processor CP750 delivers the best in surround sound from all content sources. In addition to the digital cinema formats (Dolby Surround 7.1 and 5.1 digital PCM), it also decodes Dolby Digital Surround EX™ (bitstream), Dolby Pro Logic® II, and Dolby Pro Logic.

Integrates with Dolby Show Manager Software

Integration with Dolby Show Manager software gives you a drag-and-drop interface so that you can easily build volume cues and digital input selection into a show. You also get real-time volume control from any Dolby Show Manager client and seamless processing of ASCII commands from third-party controllers.
