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 Automatic Loudness
Control (ALC) option is the solution to this
need. It uses Miranda’s proprietary
wideband
ALC algorithm.

Depending on the model, different channel configurations are possible as listed in the table above. The 2-channel
ALC supports only two independent programs (either one 2.0 program, or 2 mono programs). All other ALC models
supports up to 4 independent programs (mono channel, 2.0 channels, 3.0 channels, 4.0 channels, 5.1 channels and
7.1 channels).
Note: The ALC works with PCM audio. If non-PCM audio like
Dolby-E or AC-3 is fed to the module, it will be ignored and
all the program channels will be bypassed to prevent
interference with the other PCM audio channels.

Channels per program
Pull-downs are available to select the number of channels
per program. Depending on the ALC model, you may have
different possible selections, from 1 to 8 channels per
program.
Input channels selection
An input shuffler allows any combination of the available
channels to be used as inputs to each ALC program.
Note: An input channel cannot be assigned to more than one
(1) program.
