New functionality

[PLM, LM & LC] Most of the communication between PLM Series and LM 26 devices and the
Controller has been converted from UDP Broadcast to UDP Unicast, resulting in far less traffic
on the network. This improves performance using the Lake Controller over Wi-Fi access
points.

[PLM & LC] Bridge Mode configuration for all PLM Series models are added!
o ISVPL configuration now extends the upper configuration to 600 V to incorporate for
the double voltage of a bridge channel.
 Note: The “Level limits” available on the Control tab (in Designer mode) in
the Events & Control of the Controller will need to be extended if this has a
lower limit set.
o IMPORTANT: When Bridge Mode is activated, CLASS 3 WIRING is required.

[PLM & LC] Enhanced faults and warnings indications for PLM 20000Q. See PLM Series
Operation Manual for full details.

[PLM & LC] Digital clock slipping indication added on work area for PLM Series, LM 26 and
the Dolby Lake Processor (DLP). For PLM it is also added in Status tab and on front panel.

[PLM] Dante Clock master front panel indication added in the lower left corner of home view.

[PLM] After a complete firmware upgraded it is prompted to cycle mains power to complete
the firmware upgrade on the front panel.

[PM] Added support for PLM 20000Q in Preset Manager.

[LC] Added an illegal Dante channel name block. This will only allow standard a to z, capital
and lower case letters and 1 to 9 complemented by “-“. This due to the former ability to use
illegal characters without a proper warning and having issues with assigning Dante channels.

[PLM] Added a PSU temperature warning.

[PLM] Added a DSP area temperature warning, and the DSP area temperature will also
influence the fan speed.
o Note: DSP area temp fault will from here on not mute audio, but continued operation
without improved air ventilation is not recommended.

[PLM & LC] The Mains Current Limiter has been renamed to Breaker Emulation Limiter
Configuration.
o Also: Fuse selector -> Breaker characteristics, Slow characteristic -> Universal
characteristic.

[LC] Improved error message if the UDP port 6004 already is in use by another program and
the Lake Controller is unable to start.

[LC] Removed the confusing “AUX” string from the “Input router” selection in the LM 26 Output
routing.

[PLM] More robustness added to the PLM 20000Q PSU, so that it now can tolerate a mains
glitch (short dropout of mains voltage) and/or a mains spike.
rd
[PLM & LM] New 3 party control protocol, DLM v2, released. Please contact us for more
information.

Issues corrected

[LC] Improved performance of the Batch Replace window, particular the performance on
Windows 7 systems has been significantly improved.

[LC] Fixed a memory leak that could cause the Controller to close unintentionally.

[PLM] Updated CAL configuration for improved amplifier module protection during continuous
signals.

[LC] Fixed an issue where the use of the command line “emulation” would cause a crash after
minimize and maximize. Adding “Emulation” as a command line will improve the performance
when using the Controller in a VNC setup.
o Note: In Windows® 7, Windows Aero needs to be disabled (See Windows .

Known Issues
Windows 7 support area:
The Lake Controller is still not yet fully optimized to Windows 7. On some computers the Controller
can feel un-responsive and slow. There are a few things that can be configured in order to improve
performance:
1. Disable Power saving and Power management options
Disable all power saving options. These can be either the Windows 7 default
configuration “Control Panel\All Control Panel Items\Power Options\Edit Plan Settings
-> Change advanced power settings” or for some laptop/tablet computer brands a
standalone Power Management application that is supplied. The important
configurations that can be made in order to improve performance is:
The options for CPU and/or PCI bus and/or PCI Express. By default these are set to
Automatic/… power savings/Dynamic. Set them to Disable automatic, Off for power
savings or Maximum Performance and reboot the computer.
2. Run the Lake Controller in XP mode
Windows XP mode for Windows 7 is a feature available in Windows 7 Professional
edition only, and provides a virtual Windows XP environment in Windows 7. Use the
following link to find information and installation:

3. Turn off multicore CPU in BIOS
It has been tested that on some computers it might help to disable the multicore CPU
functionality. This is done from BIOS. Please refer to your computer manual.
4. Windows Vista display driver in Windows 7
It might increase performance of the Lake Controller to use a display driver intended
for Windows Vista instead. For some more detailed testing and explanations of this go

1. Right click on desktop and choose “Personalize”
2. Scroll down and select the Windows 7 Basic or Windows Classic theme.
Known issues with the Lake Controller and firmware

[LM] There is an issue with thought product, linked AES distribution, on the LM 26 together
with use of Dante. (J#2020)
o Workaround: Pay attention when using Dante with multiple AES clock inputs. Clock
slipping might be a potential issue. Do not route both Dante and AES between LM
26s.

[LM] AES inputs and outputs that lock to the SRC clock will not have the input and output
clock phase aligned.

[LC] When subscribing Dante channels on a receiving unit, and multiple NIC’s are active, a
error might occur if the NIC communicating to the Lake/Dante network is on another range
then 169.254.X.Y.
o Workaround: The network interface needs to be in the same IP subnet as the devices
you wish to communicate with. In this case, 169.254.X.Y. Or only have one NIC
active.

[PLM] Very rarely during the Amp firmware upgrade, the front panel can halt before 100% of
the firmware update is reached.
o Workaround: Please power cycle the frame and the firmware update will be
completed.

[LC, PLM & LM] When running a dual redundant Ethernet network, there is a possibility to run
the Controller on the secondary network if the IP on the Controller computer is changed to
range 172.31.x.x and Subnet mask to 255.255.0.0. Attaching a Controller to both the Primary
and Secondary network connections simultaneously is not possible. (J#775)

[LC] There can be issues with Super Modules if 2-way from A and B modules are combined.

[LC] When shifting Dante sample rate between 96 and 48 kHz mode, Dante needs to be
disabled and re-enabled, otherwise the channels will not be displayed. (J#1537)

[LC] Many modules on work area when enabling Dante can make the Controller close
unintentional during Dante input configuration. (J#1517)
o Workaround: Add all frames to work area, enable Dante on all frames without doing
the input configuration and channel subscription. When all frames in the system are
locked to Dante, start to configure the channels. Don't forget to change the Dante
channel name, before doing any subscription.

[PLM] When downgrading from firmware 2.68 to earlier firmware, it is required to perform a
factory reset before downgrading, and one after the downgrade. (T#1520)

[LC] With multiple Controllers 2-aux module files will not sync changes to EQ AUX-tabs
between primary and secondary. (J#1437, 1386)
o Workaround: Use 3-aux module files instead, or add any filters needed from primary
Controller.

[LC] Recalling old system files might lead to a “Mute indication” on the group icon on Work
area.
Copyright © 2010 Lab.gruppen AB. All Rights Reserved
Installer 35 - Lake Controller v5.6 build 008 – Release Notes
o
7 (21)
Workaround: De-assign all assigned modules and enter the Levels page for the group
and un-mute.

[LC] If the GEQ is changed too rapidly on different frequencies this can lead to problems
transferring and recalling settings. (J#1162, J#1201, J#1207)

[LC] When implementing very large systems, please use a computer with specifications above
the minimum requirements. Status bar error message 8, 14 and 1158 are indications of
Windows resource being exhausted. The Windows resource setting that is proposed in the
installer can help to resolve these issues. (J#708, J#660, J#769, J#861)

[LC] A system with more than one secondary Lake Controller has communication problems.
There are also a few minor security problems with secondary Controllers (J#523, J#524,
J#667, J#668, J#657, 724)

[LC] If connection to primary Controller is lost from secondary Controller, Events and Control
popup values can still be edited from secondary Controller – however these changes never
reach the frames and when connection is established to primary Controller again all changes
done on secondary will be lost. (J#1431)

[PLM & LC] LoadSmart™ warning messages can sometimes fail to be displayed on the front
panel and in the Lake Controller. (T#1133)

[LC] A Classic 3-way module loaded to module B presents an incorrect channel name on the
crossover page for the low channel (shows high instead of low). (J#578)

[PLM & LC] User interface does not synchronize front panel changes when the Controller is on
the Module B levels page. (J#585)

[LC] Amp Clip factory setting is not automatically set to the power output channel’s theoretical
clip voltage. (J#455)

[LC] The Ambient temperature can, during some operations, return to the default value.
(J#965, J#967, J#1167, J#1168)

[LC] Frames added to work area after a secondary Controller has been disconnected might
not show up on secondary Controller after a re-connect. (J#1316)

[LC] Multiple Controllers work incorrectly in systems above 65 units.

[LC] The fast sync between Controller and processors does not work as expected in all
situations, and slightly longer sync times can sometimes occur. (J#1343)
o Workaround: Store and recall the system might help in some cases.

[LC] Super Modules do not indicate on work area if the module is part standby. (J#830)
o Workaround: Double check on All-page that all frames are online.

[LC] Faults and warnings are not indicated on Super Modules that are part standby or offline.
(J#1665)
o Workaround: Double check on All-page that all frames are online.

[LC] Groups with many assigned Super Modules will have a few seconds processing time
before changes made from the group have been synced correctly. During this time there is a
GUI issue where the group name tab will flicker (J#1353)

[LC] Multiple recalls of the same Subsystem places the modules on top of each other even if
the “auto arrange” feature is turned on. (J#614)

[LC] If Recall Last System Configuration is used after a Controller restart the sorting on Allpage is altered to all A-modules and then all B-modules. (J#1436)
o Workaround: Store the system as a System file and recall this, however this will not
solve the issue for virtual modules.

[LC] The Levels page meters may lose high update rate after a re-sync. (J#489)
o Workaround: Close and open the Levels Page.

[LC] Recall compare does not work for virtual frames. (J#707)

[LC] Storing a Sub-system will update the name on the current system. (J#860)

[LC] Recalling LP 4-way module files where DSP channel 3 has maximum delay might cause
an error message to be displayed. (J#791)
Copyright © 2010 Lab.gruppen AB. All Rights Reserved
Installer 35 - Lake Controller v5.6 build 008 – Release Notes
o
8 (21)
Workaround: Re-route the specific muted power output channel to unlock the
unwanted mute.

[LC] Loading or adding virtual frames to an offline system may replace the offline real frames.

[LC] The polarity can occasionally change back to default when altering input mixer
configuration for input two. (J#1187, 1310)

[LC] Recall Compare can alter the input mute indications. (J#1163)

[LC] Storing an altered LP 4-way module file as a “New Store” will result in some Events and
control parameters being lost. (J#1426)
o Workaround: Double check the Events and control parameters for this module.

[LC] Cable data for LoadSmart functionality does not get copied during a copy / paste action.
(T#1492)

[LC] Copying of LP 3-way might cause rounding errors on Xover frequency. (J#908)
