Routing Channels for Dolby AtmosĀ® Bed Mixing

Mixing for a 7.1.2 Dolby Atmos audio bed requires a signal routing to a 7.1.2 output bus.

When mixing for a Dolby Atmos audio bed, the following applies:

  • You must route the source channel to a 7.1.2. output bus or group channel.

    To ensure the correct routing for the Dolby Atmos mix, we recommend to route the first 10 device ports of your audio interface to the 7.1.2 output bus. You can select the device ports in the Audio Connections window.


    In Nuendo, the order of surround busses and side busses differs from the Dolby specification for side surround busses (Lss, Rss) and surround rear busses (Lsr, Rsr). To meet the specification for the Dolby Atmos Renderer, swap the device ports of surround busses and side busses.

  • You can route mono, stereo, or 2D surround channels to a 7.1.2 bus or group channel. If you route a 7.1.2 channel to a bus or group channel in 7.1.2 or another 3D channel configuration, MixConvert V6 is used for panning.

  • Plug-ins that are used in a 3D bus or group channel must support a corresponding number of channels.
