    Dolby Digital Cinema Processor CP750

    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.

    Controlled from Anywhere

    The Dolby CP750 is ready for the network operations center (NOC) and can be monitored and controlled anywhere on the network for status and function. Hearing-impaired (HI) and auxiliary analog outputs complement the Dolby CP750's main eight-channel audio output.

    Cinema Sound Processors

    Dolby cinema processors deliver the highest-quality digital cinema playback of Dolby soundtracks, as well as the Dolby consumer codecs commonly used for alternative content.
