Final Stage 
 

This final section of the processor is where the final look-
ahead peak limiter and bass soft clipper are adjusted. The 
look-ahead limiters are wideband, limited to 6dB of gain 
reduction, are extremely fast, and due to their look-ahead 
nature are virtually transparent even at full gain reduction. 
Their purpose is to control peaks that make it through the 
multiband section. Adjustable parameters are: 
 

•

 

Final Limiter Drive: -6dB - +6dB (default: -5dB). Sets 
the level at which the wideband sum of all bands is fed 
to the final limiter. 
 

•

 

Output Level: -36dB - 0dB (default: -13dB for PGM1, -
11 dB for PGM2). Sets the output level for the current 
preset. Can be used to match the measured loudness 
of one preset to another. This is useful as more 
aggressive presets will measure differently from less 
aggressive versions.

tm

  

Surround Field Adjustments 

The “surround field” can be adjusted with the Center channel Width 
control and the Surround channel Depth control. 
 

AutoMAX-II Transition Speed 

When the upmix operates in AutoMAX-II

tm

 mode, the speed of the 

transitions from 2.0 to 5.1, and 5.1 to 2.0, can be configured to 
provide smooth and unobtrusive changeovers. 

•

 

Set the “Upmix-to-Pass” and “Pass-to-Upmix” transition 

speeds independently, over the range 

Instant

 to

 Very Slow

 

5.1/2.0 Detection Threshold 

This parameter is used when the upmix operates in AutoMAX-II

tm

 

mode to detect silence on some of the 5.1 channels to determine if 
5.1 or 2.0 is detected. 
 

LFE Output Channel 

The bass enhancement signal for the LFE channel is derived from 
the Left, Center and Right channels. The LFE checkbox and LFE 
Channel Level slider control the LFE output
