Demystifying Dolby Atmos - The Dolby RMU


What is the Dolby RMU?

There are technically 2 variations on the Dolby Rendering and Mastering Unit (RMU). The Dolby RMU for theatrical applications and the Dolby / Dell RMU for near field (home theater), designed for Blu-ray, digital delivery (streaming) and VR content. Although both of these devices have much in common, they are not interchangeable.

The Dolby Rendering and Mastering Unit (RMU) for near field application is a powerful, Dell Server host computer custom built by RSPE Audio Solutions and housed in a 19 inch rack unit. The RMU does all of the processing for managing pans, room calibration and configurations and houses MADI IO for input and output to your Pro Tools rigs, and speaker monitoring system. Each RMU is built and certified by one of RSPE Audio's Certified Dolby Specialists.

The RMU features preinstalled software to perform various tasks in a Dolby Atmos authoring and mix workflow. The Dolby Atmos Designer application is used to calibrate the mix stage and create the room's speaker configuration. The Dolby RMU web client in tandem with the Monitor application, is used to modify Renderer software operations such as loading room configurations, audition a Dolby Atmos mix, record a print master, or play back a print master.

The Dolby RMU for theatrical use is not available for sale. It is only available through a special loan and licensing agreement between Dolby and the filmmaker that also requires the attendance of Dolby engineer when creating final theatrical printmasters.
