 DRC

 is the Dynamic Range Control portion  of an Instance which provides loudness control 

and audio processing including downward expansion and parametric equalization (PEQ) in 
addition to mulriple stages of single band and wide band (WB) processing.  Each Instance has 3 
or more  DRC engines; DRC 1, DRC 2 and DRC 3 (also called DRC Local) are the minimum number 
for any instance.  In the AERO.100 interface, DRC 1, DRC 2 and DRC Local are sometimes 
referred to as DRC - Program 1, DRC - Program 2 and DRC - Local.  An AMX5x2 engine has five 
DRC engines; DRC 1a, DRC1b, DRC 1c, DRC 2 and DRC3 

DRC Local (

or just “Local”) is the DRC with the capability to replace the output of DRC 1(a), 

DRC2, or or both DRC 1(a) and DRC 2 programs, with locally inserted audio.  The replacement 
can be triggered by GPI, by IP command or manually. 

Please see the block diagrams of the AMX5.1 and AMX5x2 and AMX2.0 instances for more 
information about signal flow. 

DARS

 is “digital audio reference signal”.  This is an AES digital audio signal and can be silent or 

contain audio.  A timing reference is derived from the AES signal’s timing.  This is NOT word 
clock. 

DVS 

is descriptive video service 

SAP 

is secondary audio program

AERO.100 Basics    

The Linear Acoustic AERO.100 Audio Loudness Manager is a state-of-the-art, adaptive, 
multiband, broadcast audio loudness controller with one or (optionally) two processing 
Instances, each of which can be an AMX5.1, AMX5x2 or AMX2.0.  
 
Each processing engine within the configuration can apply loudness control to the incoming 
audio content.  An AMX5.1 can accept either discrete 5.1 audio or 2.0 content and upmix 2.0 
content to 5.1 surround.  The 2-channel DRCs can function as independent stereo processors 
for other audio programs such as SAP or DVS, or provide an Lo/Ro or Lt/Rt downmix of the 5.1 
output (including automatic replacement of a downmix in the absence of SAP audio) and,
