Note: To play back Dolby Atmos content in a CP950A, the macro must have Dolby Atmos sync
assigned to channel 14.
Note: The Dolby CP950/CP950A actively monitors any AES3 channels that are in use for the current
macro and sends alerts if the system detects that one or more channels is intermittent or
disconnected. If you are using Dolby Fidelio or another accessibility system that removes channels 7
and 8, you must edit your 5.1 and 7.1 Dolby Surround macros to prevent false alerting. To edit these
macros, change from the Dolby preset to the custom preset, and then change channels 7 and 8 to not
used.
To change the Dolby presets, click on the custom button, and then click in the respective fields to select the
desired channel assignments, as shown in the following figure, which uses a CP950A as an example.
