NLC5.1 User Manual Revision A.1 for firmware 4.01.01. 

NLC5.1ST Key Features 

 

 

Simultaneous 5.1 surround and 2.0 auxiliary stereo loudness control signal flows 

 

Industry-standard ITU-R BS.1770/1 and DTS-Neural Loudness Measure (NLM) 
algorithm; simultaneous measurement for 5.1 surround and auxiliary stereo inputs 

 

Robust DSP platform – no PC operating system to hang; no lengthy boot-ups 

 

Three factory-defined loudness control parameter presets and four user-
controllable presets to instantly tailor the operation of NLC5.1ST to match the 
program material 

 

GPIO interface allows for automatic selection of bypass modes or changing 
presets 

 

Ethernet interface for long-term logging and field software updates 

 

Optional HD/SDI input for de-embedding program audio for loudness control
