Digital Cinema Processor
Dolby CP750 Digital Cinema Processor Features
Freestanding Digital Cinema Processor Saves cost of maintaining a legacy cinema processor coupled with a D/A adapter when film processing is no longer a requirement
Eight-Channel Digital Input (4 × AES/EBU) for Digital Cinema Server Plays up to eight-channel soundtrack; provides access to hearing- and visually-impaired narrative tracks when provided on 7/8
Two Digital Pair Inputs (1 × AES/EBU Each) Connects alternative content sources (preshow server, satellite receiver, etc.) for additional revenue
Toslink Digital Input Connects alternative content sources that output optical digital audio
Eight-Channel Analog Input Connects existing film sound processor for hybrid installations or retrofits
USB Connector Enables easy system setup from PC
Ethernet Connector Connects with Dolby TMS network and/or can be monitored, controlled, or upgraded anywhere on the network for glitch-free shows
Dolby TMS Software Integration Builds volume cues and digital input selection into shows with drag-and-drop ease for seamless control
