Playback Voices (In Pro Tools)

This is the total number of audio streams that you can route to and from Pro Tools audio

tracks, and physical audio outputs and inputs on your Pro Tools audio interfaces. In a

Dolby Atmos system, the primary Pro Tools audio interfaces are two Avid

HD MADI

interfaces. This is the recommended configuration when working in Pro Tools directly.

When working with a mixing console (such as an Avid System 5 or AMS Neve DFC),

there are typically several Pro Tools playback machines with smaller source sessions.

Multichannel Mixing Format

This is the number and type of channel outputs required for Dolby Atmos. In Pro Tools,

the 9.1 format represents the bed, and is mapped as a 7.1 bed output, plus a stereo

overhead output. Objects are mapped individually to mono and stereo outputs.

Channels and Track Layout

These are the default channel assignments (or mono subpaths) and their ordering (for

example, in channel outputs and meters). Channels are configured in

I/O Setup and are

available for use as track outputs and sends in the session. For greater-than-stereo

multichannel tracks, Pro Tools internal routing uses standard film channel ordering.

Note:

Channel layout for Pro Tools outputs and meters do not match the

ordering of the MADI inputs of the Dolby RMU. Internally, Pro Tools uses

film channel ordering. RMU Inputs use SMPTE/ITU channel ordering. See

Routing Pro Tools Physical Outputs to RMU MADI Inputs.

3.1.2 Routing Pro Tools Physical Outputs to RMU MADI Inputs

The Dolby RMU MADI inputs use SMPTE/ITU channel ordering. When configuring Pro

Tools physical output paths in

I/O Setup, order the outputs to match the ordering of the

MADI inputs of the RMU, according to the assignments listed in the following table.
