NLC5.1ST User Manual 

The root display shown on NLC5.1ST when first entering the menu is demonstrated above. To enter 
the root programming menu, press the ENTER key from the home screen while the unit is unlocked. 
From the main menu screen you may navigate to the desired sub-menu by pressing ENTER.  
 

Algorithm Meters Menu 

 
 
 
 
 
 
 
 
 
 
 
 
 
The Algorithm Meters menu contains all the real-time loudness readings that NLC5.1ST generates for 
the audio—both before and after processing. Each measurement is rounded up to two decimal places 
of precision.  
 

5.1 In Short Average

: The measured short term smoothed combined average of the 5.1 signal input.  

 

5.1 In True Peak

: The measured instantaneous highest true peak value of the 5.1 signal input during 

the current measurement period.  
 

5.1 Out Short Average

: The measured short term smoothed combined average of the 5.1 output.  

 

5.1 Out True Peak

: The measured instantaneous highest true peak value of the 5.1 signal output 

during the current measurement period.  
 

5.1 Out Correction

: The amount of attenuation or gain that was applied to the 5.1 input signal in order 

to bring the loudness within the target.  
 

5.1 Out Compression

: The amount of dynamic range compression that was applied to the 5.1 input 

signal in order to bring the loudness within the target.  
 

ST In Short Average

: The measured short term smoothed combined average of the auxiliary stereo 

signal input.  
 

ST In True Peak

: The measured instantaneous highest true peak value of the auxiliary stereo signal 

input during the current measurement period.  

 
ST Out Short Average

: The measured short term smoothed combined average of the auxiliary stereo 

signal output.  

 
ST Out True Peak

: The measured instantaneous highest true peak value of the auxiliary stereo signal 

output during the current measurement period.
