在设置Bed音频时，应该是什么样的声道顺序？

输出到杜比全景声渲染器的Bed音频必须使用SMPTE的通道顺序（不论是5.1还是7.1.2），即L=1, R=2, C=3, LFE=4, Ls=5, Rs=6, Lrs=7, Rrs=8, Ltm=9, Rtm=10。如果使用HDX、Native或Dolby Audio Bridge作为Pro Tools播放引擎，这个必须在I/O设置中的Output页面正确设置。如果使用实时Re-Render，需要在I/O设置中的Input页面中设置同样的通道顺序。

如果使用使用Nuendo通过硬件输出或Dolby Audio Bridge，可以在Audio Connections窗口中为Bed音频设置SMPTE通道顺序。

如果在Pro Tools中使用渲染器Send/Return插件与DAPS进行工作，在多个辅助轨道上使用Send插件向渲染器发送Bed音频时，为插件的Send设置如下通道顺序：L = Send 1, R = Send 2, C = Send 3, LFE = Send 4, Lss = Send 5, Rss = Send 6, Lrs = Send 7, Rrs = Send 8, Lts = Send 9, Rts = Send 10。当使用一个多重单声道的辅助轨道时，首先点灭插件的Link按钮，以将插件各通道解除关联，然后即可在Link按钮下方的菜单中为每个通道设置正确的Send通道。渲染器的扬声器输出返回工作站时也使用同样的通道顺序。

What channel order should be used for assigning bed audio to the Renderer ?

Bed audio output to the Dolby Atmos Renderer must use SMPTE channel ordering for 5.1 to 7.1.2 (L=1, R=2, C=3, Lfe=4, Ls=5, Rs=6, Lrs=7, Rrs=8, Ltm=9, Rtm=10). If using the HDX, Native, or the Dolby Audio Bridge as the playback enginer in Pro Tools this must be configured in the output page of the I/O Setup. Live Re-Renders require the same channel order if used and must be configured in the input page of the I/O Setup in Pro Tools.

If using hardware outputs or the Dolby Audio Bridge from Nuendo, SMPTE channel ordering for Bed audio is set in the Audio Connections window.

If using the Renderer Send and Return plugins with the Dolby Atmos Production Suite in Pro Tools, this channel order must be using when using multichannel aux tracks to send Bed audio to the Renderer. Sends should be assigned to the sends in the following channel order L = Send 1, R = Send 2, C = Send 3, LFE = Send 4, Lss = Send 5, Rss = Send 6, Lrs = Send 7, Rrs = Send 8, Lts = Send 9, Rts = Send 10. When using a multi-channel aux track “unlink” to assign each channel to the appropriate send from the channel drop down menu under the link button. Speaker outputs from the Renderer using mutlichannel aux tracks must use the same channel order
