An AMX5x2 Instance is capable of processing five stereo programs. One source can be
5.1 or mixed 5.1 and stereo. The 5.1 source will be downmixed. AMX5x3 is also referred
to as 2+2+2+2+2.
In addition to multiple independent loudness control processors (called DRC1, DRC2, or
DRCLocal) an Instance has many other processing functions. These include:
•
Two UPMAX II upmixers, one for main program and one for local insert. (In AMX5.1
instances only)
•
Automatic and seamless switching between surround and upmixing of stereo inputs
(AutoMAX)
•
Downmixing (Lo/Ro or Lt/Rt)
•
Creation of dual channel mono from one channel of an input pair (for SAP, DVS and local
emergency audio)
•
Automatic replacement of SAP (or any stereo/mono source) with a downmix of the main
channel
•
SDI source pair shuffling and embedding of AES digital audio inputs into the SDI output
•
Local program insertion
•
EAS or local emergency audio insertion
A
DRC
is the Dynamic Range Control portion of an Instance which provides loudness control.
Each Instance has 3 or more DRC engines; DRC 1, DRC 2and DRC Local are the minimum
number for any instance. In the AERO.2000 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 1, DRC2, DRC 3, DRC4 and DRC5 (or DRC Local
DRC Local (
or just “Local”) is the DRC with the capability to replace the output of DRC 1, DRC2,
or or both DRC 1 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 5.1 and 2.0 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.
AES
is sometimes used in the manual as an abbreviation for an AES-3 digital audio connection.
