8 sIGNAL FLOW AND PROCEssING
When a PLM-specific loudspeaker type is loaded,
its load characteristics are included. The load
characteristics are stored in a file with a ".mdl"
suffix and is loaded with the module file with the
same name. The PLM's LoadSmart and SpeakerSafe
systems use this data to verify and monitor the loads
before and during performance. See Dolby Lake
Controller User Manual PLM Edition Addendum
for more information concerning LoadSmart and
SpeakerSafe operation.

8.3.2 super Modules

A Super Module allows the user to control multiple
Modules of the same type, distributed across
multiple Frames, as a single entity within the DLC
PLM Edition software. Any changes made within
the Super Module are replicated in all the assigned
Modules, resulting in improved efficiency in system
configuration and a reduction in on-screen icons
within the DLC PLM Edition software.
Consider the case of Modules in three PLMs being
configured as Classic 3-Way Crossovers. In this case
each PLM has Hi, Mid and Low outputs, but one
spare input and one spare output is available on each.
In this case, a total of three spare inputs and outputs
are available. In order for these not to go to waste it
is possible to combine them as a Super Module. By
allowing utilization of available DSP across multiple
frames, this Super Module is capable, for example,
of providing an additional 3-way crossover.
In this example, it would be necessary to parallel the
'spare' inputs on each of the three PLMs together.
The Hi, Mid and Low outputs would be spread across
the three PLMs.

8.4 Presets

The Dolby system provides four types of Presets:
Module Files, Frame Presets, Subsystem Presets
and System Presets. These can be used to store
Module configuration data on a per-Module or per-
Frame basis, or globally across the entire system of
networked PLMs.

8.4.1 Module files

Once a Module has been configured for a specific
26 PLM Series Operation Manual
speaker system (including crossover, EQ, limiter and
delay settings) it is good practice to store the data in
the PC. This allows the Module configuration data
to be loaded into other Modules on the network or
stored for future use. It is not possible to store a
Module File (or configuration file) within the PLM. For
further details on storing Module data see chapter 7.5
(Module Store/Recall) of the Dolby Lake Controller
User Manual. Module files based on modules from
the LoadLibrary will also include the loudspeaker
specific fingerprint data.

8.4.2 Frame Presets

A maximum of 100 Frame Presets can be stored
within the PLM's processor. The data within a Frame
Preset includes the configurations of all Modules in
the Frame: gain, delay and limiter levels; input mixer
configurations; and output routing information. As
Frame Presets are stored within the PLM, complete
processor configurations may be recalled without the
need to connect the PLM to a PC.
Frame Presets can either be recalled via the DLC
PLM Edition software, or via the PLM front panel
display. See chapter 9.12.6.1 (Recall Frame Preset
submenu) in this document and chapter 5.7.3 (Frame
Presets) of the Dolby Lake Controller User Manual
for further information.

8.4.3 subsystem Presets

The Subsystem Presets function allows selected
Module and Super Module configurations to be
stored from a larger system of networked PLMs
and Dolby Lake Processors.
For further information see chapter 6.7 of the Dolby
Lake Controller User Manual.

8.4.4 system Presets

The System Presets function allows entire system
configurations to be stored in a network of PLMs and
Dolby Lake Processors. This enables fast retrieval and
switching of configurations as there is minimal data
being sent between the Controller and processors.
For further information see chapter 6.7 of the Dolby
Lake Controller User Manual.
