When a 6.x channel layout is selected, the second extra channel (i.e. the third fader in each group) will 
not be selectable as it is not required for the selected channel layout. Furthermore, when using the 6.x 
Discrete channel layout, only the 
 is valid. If this button is not activated for the 6.x 
Discrete channel layout, an error message will be displayed informing the user to activate this button. 
  Note: When selecting 5.1-channel downmix values for all stream types except DTS-HD Master 
Audio, the L, R, C, LFE, Ls and Rs channels must have the same scaling value. In the DTS-HD 
Master Audio stream type case, for a 5.1 channel downmix, the scaling value for these channels 
can be different. 
  Note: If the selected channel layout is 5.0, 6.0 or 7.0, the faders under LFE will be deactivated as 
this channel is not included in the selected channel layout. 
7.4.2  Downmix Saturation Check 
The Downmix Saturation Check feature allows a user to check for Saturation (or clipping) in the 5.1 
downmix. When the 
 button is clicked, a File Save browser will display to allow a user 
to pick the output directory and file name for their saturation check results log file. Once a directory and 
file have been selected by the user, a new job will appear in the Encode Queue with an identical name to 
the file name they just chose. When run in the Queue, the Downmix Saturation Check will perform a 
‘fake’ encode which will result in a log file containing all saturation warnings (clipping) that were 
encountered. No encoded file will be created. 
  Note: A saturation or clip in the downmix will be recorded anytime 0dBFS is reached for 3 or 
more consecutive samples.  
  Note: Downmix Saturation Check will be disabled when the ‘Folder-Based Encode’ function is 
active 
  Warning: Downmix Saturation Check ONLY checks Saturation in the 5.x downmixes for 7.x 
(Master Audio and High Resolution) and 6.x Discrete (Master Audio) channel layouts. 
  Warning: The Downmix Saturation Check runs a ‘mock’ encode based on the parameters of the 
Encoder at the time the 
 button is clicked. If ANYTHING is changed that would affect 
the Downmix after the Saturation Check is performed, the previously run Saturation Check 
should be considered invalid. Each Final Encode log file should always be looked at to ensure 
the final ‘Actual’ encoded file does not contain Saturations in the Downmix. (All Saturations 
will be located towards to bottom of the related encodes log file)
