Dolby CP850 Cinema Benefits

Dolby Atmos® provides a unique approach to cinema audio, giving filmmakers unprecedented power and freedom to realize their creative visions. In your cinema, Dolby Atmos gives audiences a natural and enveloping sound experience that fully reflects the original artistic intent.

Benefits include:

  • Plays up to 64 audio channels for an unmatched audience experience
  • Sophisticated EQ processing optimizes playback for all content types, even in acoustically challenging environments
  • Flexible configurations provide all the common I/O interfaces for the modern digital cinema
  • Automated calibration ensures consistent, high-quality playback for each movie

Dolby Commissioning Service

Each Dolby Atmos Cinema Processor CP850 includes the Dolby Commissioning Service: a complimentary review of the speaker configuration design and an initial room equalization. Our Content Services consultants will review your design drawings and equipment selection to ensure that your theatre delivers the highest-quality experience possible.

Dolby Atmos Interface DAC3201

The Dolby Atmos Interface DAC3201 allows you to use legacy amplifiers in Dolby Atmos installations. The DAC3201 employs an audio-over-Ethernet protocol, to receive the digital audio stream from the CP850. It then converts the digital audio to analog audio for connection to amplifiers. Each DAC3201 supports up to 32 analog outputs.

A Dolby® CP850 cinema processor together with a single DAC3201 can support up to 48 output channels. Installations with more than 48 output channels will need two DAC3201 units.
