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.

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.
