6.5 N-channel ALC and upmix licensed by Linear Acoustic
Minimizing loudness differences between
segments in a playout channel is an important
issue in a world where multiple programs
originating in different formats from different
sources must be integrated seamlessly. The
MOD-LA-ALC Automatic Loudness Control
(ALC) module is the Miranda/Linear Acoustic
solution to this need. It uses Linear Acoustic’s
AeroMAX
tm
multiband loudness control
algorithm.
• Identified as MOD-LA-ALC-X-YYY on the module tab where X can be 2, 6 or 8 input channels and –YYY is the
optional –DUP UpMAX
tm
module. The table shows the available MOD-LA-ALC models.

PGM 1 PGM2
MOD-LA-ALC-2 2-Channel ALC licensed by Linear Acoustic Up to 2.0 N/A
MOD-LA-ALC-2-DUP 2-Channel ALC and upmix licensed by Linear Acoustic Up to 5.1 N/A
MOD-LA-ALC-6 6-Channel ALC licensed by Linear Acoustic Up to 5.1 N/A
MOD-LA-ALC-6-DUP 6-Channel ALC and upmix licensed by Linear Acoustic Up to 5.1 N/A
MOD-LA-ALC-8 8-Channel ALC licensed by Linear Acoustic Up to 5.1 Up to 2.0
MOD-LA-ALC-8-DUP 8-Channel ALC and upmix licensed by Linear Acoustic Up to 5.1 Up to 2.0
Depending on the model, different channel configurations
are possible as listed in the table above.
The 6-channel ALC supports only a single program (either
5.1 or 2.0, but 4, 3 and 1 can be used), but the 8-channel
ALC supports 2 independent programs.
• The first program (PGM 1) can only be configured as
a single program 5.1 ALC or a 2.0 ALC. It is not
possible to configure it as a 3x2, a 6x1 or any other
channel combination with more than one program. If
you are using only 3 channels (left, right and center),
you can use the 5.1 configuration and leave the
other 3 channels assigned to silence channels. You
can even use the 5.1 ALC for a single mono channel
as long as the other channels are assigned to
silence channels.
• The second program (PGM 2) can only be
configured as a 2.0 stereo program, but you can use
it as a single mono program.
