Lake Controller Designer Mode Manual v3.2
Chapter 1: Introduction to Designer Mode
The Lake Controller software provides two modes of operation: User and Designer Mode.
This manual describes the Designer Mode and should be used in conjunction with the Lake
Controller User Mode Manual.
Some important functions that Designer Mode activates include:
ƒ
Global Access Security
ƒ
Individual Overlay/Screen Access Security
ƒ
Level Limits
ƒ
Factory Levels (Adjust Factory Mode)
ƒ
Password Protection of Modules and Base Configurations
ƒ
All Pass Filters
ƒ
Designer Worksheets
ƒ
Polarity Locking
This document provides detailed descriptions of these functions. An example system design
illustrates the utility of Designer Mode functions. A quick reference guide provides a high
level overview of Designer Mode functions.
We recommend reading the Lake Controller User Mode Manual before reading this
document.
This document refers to a Contour processor in the examples, although all features (with the
exception of crossovers) also apply to the Mesa EQ processor.
1.1 Security Levels
Designer Mode provides three levels of password-protected security that can be applied to
a system configuration.
1.1.1 Global
At the global level, a simple selection makes system-wide changes that affect what
can be seen or adjusted in User Mode. A system designer can choose to hide any
combination of EQ overlays, crossover/HPF/LPF tabs, levels, and meters. These
items can also be set to View Only, allowing a User Mode operator to view, but
not change certain information.
NOTE: Global settings are saved in the system configuration file.
7
Lake Controller Designer Mode Manual v3.2
1.1.2 Module
Individual EQ overlays and crossover tabs can be hidden or set to View Only.
Additional settings normally invisible in User Mode can also be adjusted and
hidden at module level.
At the module level, changes are specific to individual modules and Groups.
Discrete password protection can be applied to modules, providing an additional
level of security.
1.1.3 Base Configuration
Base Configuration is the lowest level of security, enabling the system designer to
define an underlying base EQ curve and crossover settings along with factory
levels and level limits. A system designer can restrict what can be seen or adjusted
and provide optional password protection to the underlying settings.
NOTE: The Lake Controller is not shipped with base configuration files. These can be created if
required using the default module files as explained in section 2.1.4.
1.2 Designer Mode
The functions available in Designer Mode can be used with or without password
protection. By default, the Designer Mode password is empty, allowing unprotected
access to Designer Mode in a new installation of the Lake Controller software.
To access Designer Mode:
1. From the Home level, tap User Preferences
2. Tap Designer Functions
3. Tap Designer Mode
Additional buttons on the button-bar become active, providing functions specific to
Designer Mode as shown in Figure 1-1.
Figure 1-1
When Designer Mode is active, the characters ‘DM’ appear next to the Lake logo in the
bottom left of the screen:
Figure 1-2
8
Lake Controller Designer Mode Manual v3.2
1.2.1 Password Protection of Designer Mode
Each software installation has one Designer Mode password. This password is
stored on the host computer and is relevant for any system configuration.
To password-protect Designer Mode:
1. Tap the Change Password button
2. Enter a password and tap OK
3. Confirm the password and tap OK
It is important that you record the Designer Mode password in a safe place. Once
the password is set, it will always be required to enter Designer Mode.
NOTE:
If the Designer Mode password is forgotten, please contact
support@proaudio.lake.com for details on password retrieval.
1.2.2 Simple Designer Mode System Security
If multiple levels of security are not required for your Lake Controller installation,
exiting Designer Mode activates all security features described in this document
without needing to lock or password-protect individual modules or base
configuration files.

Lake Controller Designer Mode Manual v3.2
Chapter 2: Designer Mode Security
2.1 Security for the Base Configuration
A base configuration file contains EQ, levels, crossover, HPF/LPF information for a
particular speaker type. A base configuration file can be used to create a standard starting
point for a particular make and model of speaker; this can then be used in a variety of
system configurations and fine-tuned using module and group settings.
The base password is saved with the base configuration file, and is stored at the hardware
level when loaded into a processor. This prevents access to certain data stored in the base
configuration file, even if you are in Designer Mode in the Lake Controller. Using a base
password allows hiding of your custom settings from any user of the Lake Controller
system.
NOTE: The base configuration file hides EQ curves, crossovers (Contour) or HPF/LPF (Mesa
EQ) and converts group and module levels to hidden ‘Factory’ values. The use of base
configuration files is recommended only for experienced Lake Controller users who
require this additional level of security and functionality. Module files provide additional
functionality to base configuration files and can be used instead of base configuration
files in most circumstances.
2.1.1 Crossover and Output EQ
All information in the Xover screen (Contour) or HPF/LPF screen (Mesa EQ) is stored
in the base configuration file, including crossover frequencies, crossover type (e.g.,
Bessel, Butterworth, or Linkwitz/Riley) along with any output-specific EQ, HPF/LPF
settings, and crossover access status. All data in the Xover screen can be adjusted for
each module, unless the designer has applied security to the base configuration file. See
section 3.4.2 for further information on locking a base configuration file.
A base configuration file cannot be loaded into a module running a different DSP
program. For example, a 2-way base configuration file cannot be loaded into a module
that is currently running a 3-way module program; a 2-way module program must be
loaded first.
2.1.2 PEQ and GEQ
All module and group EQ overlays are combined and stored as an invisible default EQ
curve for the new base configuration. Once stored in the base configuration files, this
default EQ curve cannot be viewed or adjusted, although further EQ overlays can be
created at the module or group level. When the new base configuration file is loaded into
a different module, the main EQ appears flat. Output-specific EQ from the XOVER or
Output EQ screens can still be viewed or adjusted, unless the system designer has
protected it.
11
Lake Controller Designer Mode Manual v3.2
NOTE: The EQ curve created in the PEQ and GEQ overlays is separate from any outputspecific EQ created on the Xover page. (Applicable to Contour processors only)
2.1.3 Levels
With the exception of Limiter Time Constants, and Limiter/Soft Clamp Corners, current
module and group levels are combined and stored as factory levels when a base
configuration file is saved. The factory levels can be viewed and adjusted in Designer
Mode after activating the Adjust Factory option in the Levels/Meter Options menu.
Level Limits, also stored with a base configuration file, can be viewed and adjusted from
Levels/Meter Options->Levels Limits.
2.1.4 Base Configuration Tutorial
This tutorial illustrates important features of base configuration files, using a Contour
processor as the example. For Mesa EQ processors, use the only output available on
each module instead of output 2/3 etc. and ignore the steps regarding crossovers.
Adjust Levels and Level Limits:
1. Navigate to the Gain levels page of Module A.
2. Adjust the Output 2 gain to -9 dB.
3. Tap the Delay button and increase Output 3 delay to 6.00 ms.
4. Tap Meter Options then tap Level Limits.
5. Select Gain/Delay Limits.
6. Tap the Max Delay value highlighted in blue for the Input channel. This is
located on the left of the screen, 2nd from bottom and should initially read 1800.00
7. Enter 0 (zero) and tap OK.
Setting a maximum value identical to the minimum value removes the fader when in
User Mode, or when the base configuration file or module is locked.
Adjust Crossover Settings:
8. Tap the EQ tab (top-left) and select XOVER (Contour) or HPF/LPF (Mesa EQ)
9. With the first output (low frequency) selected, tap Crossover Select
(Contour only)
10. Select 36dB Butterworth from the scroll-bar (Contour only)
11. Tap Crossover Set then tap YES to the warning message (Contour only)
12. Tap HPF Enable located at the top-left of the screen (Contour and Mesa EQ)
13. Tap Xover Functions from the button-bar then tap Crossover View Only
This hides the crossover screen (Contour) or HPF/LPF screen (Mesa EQ) when in User
Mode, or when the base configuration/module is locked.

Lake Controller Designer Mode Manual v3.2
2.1.5 Summary
Base configuration files enable low-level security allowing control over individual
aspects of the system. The system designer can fine tune a speaker configuration
(Contour), or system EQ (Mesa EQ) and protect the settings by hiding or setting them as
view only.
The base configuration files can be saved and loaded into other modules in the same
system, or in different systems. This provides a starting point from which the module
can be fine-tuned by another designer or user.
NOTE: The Module Properties screen displays the name of the base configuration file that was
originally loaded, or most recently saved. Module Properties can be found under the
Modules menu.
2.2 Security for Module Functions
All settings that can be protected for a base configuration can also be protected for a
module. Base configuration settings are overwritten by module settings, unless access has
been restricted in the base configuration file, in which case certain parameters will not be
accessible. The base configuration file itself will not be affected by any changes made to a
module after the file is loaded.
The module password is saved with the single module file, and is stored at the hardware
level when loaded into a processor. This prevents access to certain data stored in the
module file, even if you are in Designer Mode in the Lake Controller. Using a module
password allows hiding of your custom settings from any user of the Lake Controller.
The following features are available for both base configuration and module files:
ƒ
Adjust and lock factory levels
ƒ
Adjust and lock access to crossover settings
ƒ
Hide unused channels
ƒ
Adjust level limits
ƒ
Disable individual level faders or entire level sections from other designers (using
Level Limits and Module Lock)
In addition to these features, a system designer can also adjust and lock access to
individual PEQ and GEQ overlays.
2.2.1 Module Tutorial
The tutorial below illustrates Designer Mode’s most important features about modules.
It also includes some functions that relate to both base configuration and module files,
such as Level Limits. Use the same Designer Mode Tutorial system configuration from
section 2.1.4. Ensure you are in Designer Mode and the base configuration is unlocked
before proceeding.
15

already locked following loading the module file). All updates made in section
2.1.4 also remain.
2.2.2 Summary
Modules can store and secure all data that a base configuration can. In addition,
the module can restrict access to Input EQ overlays.
2.3 Security for Group Functions
Groups are used to connect and adjust multiple modules. Groups cannot be locked or
password-protected, but individual EQ Overlays can be hidden. Global Access settings
described in section 2.4 Security for Global Access Functions also apply to groups.
Security for levels and crossovers is not relevant for groups.
A group may contain various types of modules, each with different security settings.
However, group levels are restricted by the level limits set for the modules within the
group. For example, if changing a group level causes one or more modules to exceed their
min/ max level limits, the action is not permitted.
2.3.1 Group Tutorial

14. Tap Designer Mode to return to User Mode (button becomes blue)
15. Tap Home then tap the Group 1 icon and navigate to EQ
PEQ1 is hidden and its filter is not displayed in the EQ curve, although its effect is
still audible. GEQ2 is displayed as View Only and most functions are disabled.
2.3.2 Summary
Because a group may contain various types of modules with different security
settings, group security is limited to EQ overlays only. Crossovers are not relevant
to groups, and all security for levels is controlled via individual modules.
2.4 Security for Global Access Functions
Global Access settings affect all modules and groups within a system configuration. To
enable Global Access Mode:
1. From Home, tap User Preferences
2. Tap Designer Functions (ensure Designer Mode is active – orange)

3.3.3 Restrict Level Adjustments
Level Limits are used to restrict minimum and maximum levels for a module.
Although a group’s Level Limits cannot be set, they adhere to the limits of all
modules that are assigned to it. For example, if changing a group level causes any
of its modules to exceed their allowable range, the action is not permitted.
1. Navigate to module Levels, tap Meter Options then tap Level Limits
2. Tap Gain/Delay Limits or Limiter/Soft Clamp Limits
3. Tap the relevant min/max level.
Each channel is displayed in the same order as the channel faders (from left to
right: Input, Output 1, Output 2 etc.)
4. Enter the limit and tap OK
Figure 3-2
3.3.4 Disable Level Adjustments
If the minimum and maximum level limits are identical for a particular channel
and level type, that control is effectively disabled. The fader for the associated
channel and level type is not visible in User Mode or when the module is locked.
Follow the steps in section 3.3.3 - Restrict Level Adjustments and set both the
minimum and maximum values of a particular level output and level type to the
same value. To verify that the fader has been removed and the level fixed, either
lock the module or base configuration, or switch to User Mode.
23
Lake Controller Designer Mode Manual v3.2
3.3.5 Disable access to a Levels Function
To disable access to an entire level function (e.g. Delay) set identical minimum
and maximum delay level limits for every channel for the module. Follow the
steps in section 3.3.3 Restrict Level Adjustments and set the minimum and
maximum values of all inputs/outputs for a particular level type to the same value.
Figure 3-3
Figure 3-2 shows an example of identical min/max settings for delay. These
settings disable the levels function on the EQ/Levels menu (Figure 3-3) in User
Mode or when the module or base configuration is locked.
Figure 3-4
3.3.6 Disable/Enable Unused Output Channels
To completely hide a levels meter/fader, set the name of fader to unused:
1. Navigate to the relevant module Levels page and tap Meter Options
2. Tap Label Channel then tap the mute/label button of the relevant channel
3. Type unused and tap OK
The meter and fader will be invisible on the software controller and the meter is
also disabled on the front panel of the processor. To enable the channel again,
change the channel label to something other than unused.
3.3.7 Set Hide/View Only Status for All Levels Screens
This function affects all Levels screens in the current system configuration.
1. From Home, tap User Preferences
2. Tap Global Access then tap Levels Hide or Levels View Only
The selected button is illuminated orange.
3.3.8 Digital Offset
This option applies only to processors with a Digital Input.
Digital Offset provides the facility to compensate for the gain difference between
the analog and digital signals. The offset for each available input can be set
independently.
1. In Designer Mode, access the module properties for an online module
24
Lake Controller Designer Mode Manual v3.2
2. Tap In A Dig Offset (Contour) or Input 1 Dig Offset (Mesa EQ)

3.4.5 Creating Descriptions/Assigning Graphics for Module Files
Text files (.txt) and bitmap files (.bmp) with the same filename as a module file
can be placed in the data/user/modules directory of your Lake Controller
installation.
When a text file is present with the same filename, the controller displays the text
when the module file is selected on the Module Store/Recall scroll-bar. When a
bitmap file is present, the graphic is displayed in place of the default module icon.
Follow the steps below to create and view module file descriptions:
1. Store a module with the filename example at the module root directory
2. Minimize the controller and using a text editor (e.g. Microsoft Notepad)
create a text file containing the text: ‘Example description for Example
Module.’
3. Store this text file in the directory:
Program Files/Lake/Lake Controller/data/user/modules directory as
example.txt (see Figure 3-5)
Figure 3-5
4. Maximize the Lake Controller and navigate to Module Store/Recall
5. Select the Module File example from the scrollbar
The text you entered appears above the Module as shown in Figure 3-6.
