1. Introduction

Thank you for choosing to upgrade your TT24 Digital Live Mixing Console with the LP48 Lake Processor expansion card. Dolby Laboratories designed the highly regarded Lake Contour™ Digital Loudspeaker processor, and worked with us here at Mackie to develop the ﬁ rst integrated Lake EQ and Lake Loudspeaker modules for a digital console.

The TT24 with an LP48 expansion card provides 10 channels of Lake Insert EQ processing, or eight channels of Lake Loudspeaker processing, or a combination of the two (ﬁ ve channels of EQ processing and four channels of Lake Loudspeaker processing).

The inputs to the LP48 are assigned in the TT Control software application running on your PC from virtually any point in the TT24 signal path. The loudspeaker processor outputs from the LP48 card can be routed to any physical output connector on the console or the DS3232 Digital Snake.

LP48 conﬁ guration is done within the TT Control software Setup>Expansion menu.

Insert EQ Features

The Lake EQ Mode provides ten EQ processors that can be inserted into any of the TT24 digital insert points. Each EQ processor can operate with the Lake Ideal Graphic EQ (28-bands) or the Lake Mesa EQ (parametric EQ).

Unlike standard graphic equalizers whose adjacent ﬁ lters interact and add to each other, the Lake Ideal Graphic EQ provides a frequency response curve exactly like the curve of the user interface sliders. This allows you to have more precise control over your sound. What you see is what you get!

Lake Loudspeaker Processor Features

The Lake Loudspeaker Processor Mode provides a four input by eight output speaker processor (two input by four output when in split mode). It has two DSP engines that split up the work between them.

In split mode, you can conﬁ gure the processor as follows:

• Two two-way crossovers

• One three-way crossover

• One four-way crossover

• Two Aux mode

When the whole card is conﬁ gured in Lake Loudspeaker Processor mode, you can conﬁ gure the processors as follows:

• Four two-way crossovers

• One four-way crossover and one three-way

• One four-way crossover and two two-way

• Two four-way crossovers

• Two three-way crossovers

• Two Aux mode

You can select from the following crossover types for each individual crossover ﬁ lter, using ﬁ lter orders from 6 dB/octave up to 48 dB/octave:

2 Aux mode

2-way Xover

3-way Xover

3-way

Xover

4-way Xover

• Bessel

• Butterworth

• Linkwitz-Riley

Important default presets allow you to set up and change between the various crossover types. Presets for EAW and Mackie loudspeakers are also provided.

Getting Started

Installing the Card

The ﬁ rst thing to do is to install the LP48 expansion card into your TT24. See the “TT24 Expansion Card Installation Instructions” that came with your LP48 for instructions on how to install the expansion card.

Updating the Software

The next thing is to make sure you have the latest ﬁ rmware for the TT24 and the latest TT Control software application for your PC. Version 1.7 or greater is required to run the LP48 card.

If you don't know the software version you are currently using, you can check your software ver sion and build number by pressing the “HELP” button on the console, application.

You can ﬁ nd the latest version of the TT24 ﬁ rmware and TT Control PC application on the Mackie website: http://www.mackie.com/products/tt24/software.html

Be sure to follow the instructions when upgrading to new software, as described in the TT24 Firmware/Software Installation guide found in the link.

It is VERY IMPORTANT that you always update the ﬁ rmware in the following order:

1. DS3232 Digital Snake (if present)

or by clicking Menu > About in the TT Control PC

2. Expansion Cards (if present)

3. The TT24 Console.

Opening the LP48 Setup Screen

Now you have installed the LP48 expansion card and updated the ﬁ rmware and software, you are ready to turn on the TT24 and start conﬁ guring the LP48 Lake Processor Card.

To conﬁ rm that the LP48 card is installed and properly recognized:

1. Press the SETUP button in the QuickMix area.

2. Touch the EXPANSION button in the MENU SELECTION window.

2. Modes of Operation

Overview

There are three Card Modes from which to choose in the Lake Card Edit window: 10 Insert Equalizers, 4x8 Speaker Processor, and 2x4 Speaker Processor with 5 Insert EQs. Select the mode of operation you want to use from the window shown below. If you make a change, you will be prompted to conﬁ rm your choice:

10 Insert Equalizers

4x8 Speaker Processor

2x4 Speaker Processor with 5 Insert EQs

Page 7

10 INSERT EQUALIZERS Lake EQ Mode

When this mode of operation is selected, the LP48 supplies up to ten 1/3-octave graphic equalizers or parametric equalizers, each of which can be inserted into the pre- or post-inserts for each channel (Analog 1-24 pre or post, Digital 25-48 pre or post, card return 1-8 pre or post), the insert for an aux send (Aux Send 1-12), or the insert for the Main Left, Right, or Mono output.

The Lake Ideal Graphic EQ™ provides tighter ﬁ lter control over traditional analog (and digital) graphic EQs. It features “raised cosine” algorithms that provide a frequency response that truly matches the curve established on the graphic interface.

If one were to the boost a conventional graphic equalizer by 6 dB at 500, 750, 1000, 1250, 1600, and 2000 Hz, the resulting frequency response would resemble the wavy curve in the top trace of the illustration below. The bottom trace shows that the same adjacent ﬁ lters in the Lake Ideal Graphic EQ sum to a ﬂ at frequency response, providing a response curve just like the one you expect when you adjust the Graphic EQ sliders.

The Lake Mesa EQ™ offers the classic shelving and parametric ﬁ lters of traditional parametric EQs. But it goes one step further by providing asymmetric ﬁ ltering for independent control over upward and downward slopes of a parametric ﬁ lter section. This is particularly useful when performing corrective adjustments to the asymmetric response patterns of all loudspeakers.

4x8 SPEAKER PROCESSOR Lake Loudspeaker Processor Mode (4x8)

When this mode is selected, the LP48 provides four 1x2 crossover modules, each accepting an input from an aux send (Aux Send 1-12), Matrix Out (Matrix A-H), or the Main Left, Right, or Mono output. can also be conﬁ gured as 1x3 (3-way) or 1x4 (4-way) crossovers, or a 1-input, 2-aux preset can be chosen.

Each input and output has a delay function for time alignment of delay stacks and drivers. In addition, each output has a limiter function to provide protection for each driver. An extensive library of presets are provided, tailored for many popular loudspeaker systems, including EAW and Mackie loudspeaker products.

The crossover modules

2x4 SPEAKER PROCESSOR with 5 INSERT EQs Split Mode (2x4 Lake Loudspeaker Processor with 5 Lake Insert EQs)

This mode provides a combination of the ﬁ rst two modes: two 1x2 crossover modules and ﬁ ve insert EQ modules. The features remain the same for each type, only the number of modules has been reduced by half for each type.

Refer to this manual’s sections regarding Lake EQ Mode and Lake Loudspeaker Processor Mode for an explanation of each of the modes contained within Split Mode.

LP48 Card Outputs

For Inserts EQs, the processed output from the card is routed to the insert point. For Loudspeaker Processor outputs, the output from the LP48 card (either 8, or 4 in split mode) can be routed using the TT Control Routing Output screen of software version 1.7 or greater.

Page 8

3. Lake EQ Mode (10 Insert Equalizers)

When this mode is selected, you can choose between a 28-band graphic EQ (Lake Ideal Graphic EQ) or a fullfeatured parametric EQ (Lake Mesa EQ) for each insert.

Source Assign

You must assign a source for each insert EQ. You can select from any analog input (1-24 pre/post), digital input (25-48 pre/post), card channel (1-8 pre/post), aux send (1-12 post), or the main left, right, or mono outputs (post). Since these are insert points, the processed signal is returned to the signal path at the selected insert point.

Edit

Click the EDIT button to open the EQ Edit window. This is where you select either the graphic EQ or parametric EQ, and conﬁ gure the various parameters of the equalizer.

EDIT

NOTE: After clicking EDIT, there may be a warning that the graphics need to be 16 bit. Usually it is OK to ignore this warning, but if you have any trouble then adjust your computer display to suit.

Page 9

The parametric EQ is the default selection when you enter the EQ Edit window. The EQ Edit window consists of a graph, with the x-axis (horizontal) representing frequency, and the y-axis (vertical) representing amplitude. The icons at the top of the graph represent a low-shelf EQ, parametric EQ, Mesa EQ, and high-shelf EQ. The the bottom of the graph provide access to other EQ options.

To conﬁ gure the parametric EQ, simply click one of the blue icons at the top of the graph and move it to the approximate point in the graph where you want it to be, then click again to place it.

Default Modules

Click on the default modules to bring up...well....the default modules.

These are the main gateway for you to create new modules from existing standard crossovers.

Default Modules

The four default crossovers are: 2 Auxiliary Outputs Classic 2-Way Classic 3-Way Classic 4-Way

Classic 2-Way

2 Auxiliary Outputs

Each of these is a standard crossover that can be altered to suit your system. EQ can be added where required, ﬁ lter slopes and types changed, and all sorts of fun.

The 2 Aux Outputs is a special case, and is shown on page 30.

Two Auxiliary Outputs

This special default module allows one input to feed two aux outputs. Each Aux can then be shaped with high and low-pass ﬁ lters, and EQ added. The details of how this is done can be found in the XOVER tab and LEVELS tab section of this manual. The 2-aux has its own set of

2 Aux mode

buttons, with similar features found in non-2-aux land. For an example of aux, suppose we have two speaker systems fed from the same source. We could shape one aux

so one speaker system receives the range from 100 Hz and up, and the other speaker system receives 60 Hz and up.

2 Auxiliary Outputs

This is the Aux-1 tab of the crossover graph.

This is the Aux-1 with HPF ﬁ lter added. Different ﬁ lter types and slopes can be added, such as Bessel, Butterworth and L-W.

XOVER Tab

For modules that are not 2-Aux outs, the following details apply.

EQ/Levels

Click the EQ/Levels button to open a graphical world representing the crossover, with frequency on the x-axis (horizontal) and amplitude on the y-axis (vertical).

Each section of the crossover can be adjusted and additional EQ ﬁ lters added to each.

With a module selected, there are two tabs at the top of the edit window, XOVER and Levels. The XOVER tab opens by default. The buttons along the bottom also change to crossover buttons and ﬁ lter buttons.

Click and drag left or right on the crossover icon at the bottom of the window to change the crossover frequency.

Here we have moved the crossover frequency down a few octaves. The low frequency section is highlighted in a nice shade of Paciﬁ c NorthWest fungus green. If you want to change the frequency by small amounts, double-click the small green box above the crossover point on the graph until the text inside it is greyed out. Moving the bottom crossover icon left and right will now change the frequency by smaller amounts, giving more ﬁ ne control. Or, you can press the Filter Edit button in the bottom row and enter the exact frequency in the pop-up keyboard. Again, do not be tempted to use the real keyboard.

Green shapes and boxes in the graphical work area refer to crossovers, and blue refers to the EQ ﬁ lters.

Click on the high frequency side of the bottom crossover icon to view and edit the high frequency section.

Click the Crossover Combine button to recombine the two output sections and lock them at the –3 dB or –6 dB point.

Crossover Select

This button gives you access to a plethora of crossover ﬁ lters that can be applied to the beginning and/or end of each band. The ﬁ lters range from 6 dB/octave to 48 dB/octave and the following designs:

Bessel Butterworth Linkwitz-Riley

These icons pop up in a scrolling window above the buttons. Use the >> and << buttons to move between the selections.

Note: The Linkwitz-Riley ﬁ lter is only available in 12 dB, 24 dB, 36 dB, and 48 dB versions. The 12 dB and 36 dB Linkwitz-Riley crossovers require a polarity inversion between adjacent crossover pairs in order to maintain a constant magnitude characteristic. For example, when using a 2-way 36 dB Linkwitx-Riley crossover, invert the polarity of the high output channel. When using a multi-way crossover, invert the polarity of every other output channel.

Crossover Set

This button highlights in blue when you select a crossover. Select the crossover you want to use, and it will be

highlighted with a yellow border outline. Click the Crossover Set button and the crossover choice will be applied after a short conﬁ rmation.

Limiter Max

This button opens up a few options for setting the limiter display and levels:

Max RMS Level

The Limiter Max button displays the true rms limiters for each output. You can adjust the limiter to activate anywhere between -30 dB to +30 dB. This is the maximum rms value allowed at that output.

Max RMS Corner

The limiter corner setting softens the limiting action by gradually introducing limiting before hitting the maximum rms value. If the limiter is set to a maximum rms value of 20 dB, and the limiter corner is set at –6 dB, limiting begins gradually at 14 dB and increases until maximum limiting occurs at 20 dB. This function is similar to an audio

compressor’s “knee” function.

Limiter Attack and Limiter Release

These buttons allow you to adjust the attack and release time of the true rms limiters. In order to maintain a true rms response, the limiter’s attack and release should be set to the same time constant. These functions are similar to an audio compressor’s attack and release functions.

Max Peak Level

The Limiter Max button displays the peak limiters for each output. You can adjust the limiter to activate anywhere between -30 dB to +30 dB. This is the maximum peak value allowed at that output.

Press Limiter Max EXIT to return to the main levels tab.

Enable Mute

This button locks and unlocks the mute buttons directly under each meter. The mute buttons are unlocked by default. When the button is orange, the mute buttons are enabled.

4.4 Groups

Groups

Groups provide powerful control over all modules in a system. Modules can be assigned to multiple groups, and each module can be a member of up to 28 different Groups.

Some of the functions that Groups enable include:

• Master Level, Limiter, and Delay control over an entire system or subsections (e.g. speaker clusters)

• HPF/LPF/Crossover/Auxiliary Output ganging, enabling a change to a crossover, or output speciﬁ c EQ to be reﬂ ected across all modules of the same type within the group

• Simpliﬁ ed control over multiple speakers or zones

Once your speakers are conﬁ gured, the modules that control the detailed individual response for each speaker can be protected with the access privileges and security provided by Designer Mode.

You can use multiple Groups to logically partition a large scale loudspeaker system. Group all modules driving the left loudspeaker array to create a left sub-master. Create Groups for the center cluster, the right loudspeaker array, and any sideﬁ ll, down-ﬁ ll, front-ﬁ ll and delay systems. Then create a single master group to enable a system-wide interface for EQ and Levels, making instant adjustments to all hardware processors on a distributed network system with a single click of your mouse.

5. Introduction to Designer Mode

The LP48 Loudspeaker Processor software provides two modes of operation: User and Designer Modes. This chapter describes the Designer Mode.

Some important functions that Designer Mode activates include:

1. Global Access Security

2. Individual Overlay/Screen Access Security

3. Level Limits

4. Factory Levels (Adjust Factory Mode)

5. Password Protection of Modules and Base Conﬁ gurations

6. All Pass Filters

This chapter 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.

Security Levels

Designer Mode provides three levels of password-protected security that can be applied to a system conﬁ guration.

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 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 conﬁ guration ﬁ le.

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 the module level.

At the module level, changes are speciﬁ c to individual Modules and Groups. Discrete password protection can be applied to Modules, providing an additional level of security.

Base Conﬁ guration

Base Conﬁ guration is the lowest level of Module security, enabling the system designer to deﬁ ne 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 LP48 Loudspeaker Processor software is not shipped with base conﬁ guration ﬁ les. These can be created if required using default module ﬁ les.

Page 55

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 LP48 Loudspeaker Controller software.

To access Designer Mode:

1. From Home, click User Preferences.

2. Click Designer Functions.

3. Click Designer Mode.

Additional buttons on the button-bar become active, providing functions speciﬁ c to Designer Mode. When Designer Mode is active, the text ‘Designer Mode’ appears above the toolbar.

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 conﬁ guration.

To password-protect Designer Mode:

1. Click the Change Password button.

2. Enter a password and click OK.

3. Conﬁ rm the password and click 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 us for details on password retrieval.

Simple Designer Mode System Security

If multiple levels of security are not required for your LP48 Loudspeaker Controller installation, exiting Designer Mode activates all security features described in this chapter without needing to lock or password-protect individual modules or base conﬁ guration ﬁ les.

Page 56

Designing and Protecting an LP48 Loudspeaker Processor System

This section discusses how to use Designer Mode to protect your system by developing an example system. The example includes detailed instructions to deﬁ ne a base conﬁ guration, lock individual module level settings, and enforce global security.

System Setup for Designer Mode Tutorial

Follow the steps below to prepare for the tutorial. Access Designer Mode:

1. From Home, click User Preferences.

2. Click Designer Functions.

3. Click the Designer Mode button and enter your Designer Mode password if prompted. (If the Designer Mode button is orange, you are already logged in to Designer Mode.)

4. Click Home to return to the main menu.

5. Place the Modules of a factory-preset processor in the work area.

Save the system:

1. Click Home then System Store/Recall.

2. Navigate to, or create a folder in which to store the ﬁ le.

3. Click New Store, enter the ﬁ lename as Designer Mode Tutorial, and click OK. Your system conﬁ guration is now ready for the following tutorials.

Designer Mode Security

Security for the Base Conﬁ guration

A base conﬁ guration ﬁ le contains EQ, levels, crossover, HPF/LPF information for a particular speaker type. A base conﬁ guration ﬁ le 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 conﬁ gurations and ﬁ ne-tuned using module and group settings.

The base password is saved with the base conﬁ guration ﬁ le, and is stored when loaded into the processor. This prevents access to certain data stored in the base conﬁ guration ﬁ le, even if you are in Designer Mode. Using a base password allows hiding of your custom settings from any user of the LP48 Loudspeaker Controller system.

Note: The base conﬁ guration ﬁ le hides EQ curves, crossovers or HPF/LPF and converts Group and Module levels to hidden ‘Factory’ values. The use of base conﬁ guration ﬁ les is recommended only for experienced LP48 users who require this additional level of security and functionality. Module ﬁ les provide additional functionality to base conﬁ guration ﬁ les and can be used instead of base conﬁ guration ﬁ les in most circumstances.

Crossover and Output EQ

All information in the Xover screen (Lake Contour) or HPF/LPF screen (Mesa EQ) is stored in the base conﬁ guration ﬁ le, including crossover frequencies, crossover type (e.g., Bessel, Butterworth, or Linkwitz/Riley) along with any output-speciﬁ c 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 conﬁ guration ﬁ le.

A base conﬁ guration ﬁ le cannot be loaded into a Module running a different DSP program. For example, a 2-way base conﬁ guration ﬁ le cannot be loaded into a Module that is currently running a 3-way Module program; a 2-way Module program must be loaded ﬁ rst.

Page 57

Levels

With the exception of Limiter Attack, Release and Limiter Corners, current Module and Group levels are combined and stored as factory levels when a base conﬁ guration ﬁ le 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 conﬁ guration ﬁ le, can be viewed and adjusted from Levels/Meter Options > Levels Limits.

Base Conﬁ guration Tutorial

This tutorial illustrates important features of base conﬁ guration ﬁ les, using loudspeaker modules as the example. 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. Click the Delay button and increase Output 3 delay to 6.00 ms.

4. Click Meter Options, then click Level Limits.

5. Select Gain/Delay Limits.

6. Click 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 click OK.

Setting a maximum value identical to the minimum value removes the fader when in User Mode, or when the base conﬁ guration ﬁ le or module is locked.

Adjust Crossover Settings:

1. Click the XOVER tab (top-left) and select XOVER.

2. With the ﬁ rst output (low frequency) selected, click Crossover Select.

3. Select 36 dB Butterworth from the scroll bar.

4. Click Crossover Set then click YES to the warning message.

5. Click HPF Enable located at the top-left of the screen.

6. Click Xover Functions from the button-bar then click Crossover View Only.

This locks the crossover screen when in User Mode, or when the base conﬁ guration ﬁ le or module is locked.

Add EQ:

1. Click the low-shelf ﬁ lter icon at the top of the screen and drag it to the work area. Add the low-shelf ﬁ lter around 80 Hz, with 3 dB of gain

2. Click Home.

Lock the base conﬁ guration:

1. Click Modules then click Module A to select it.

2. Click Label & Lock. The options are displayed.

3. Click Set Base Password, type demo, and click OK.

4. Type demo again to conﬁ rm, and click OK to message.

Page 58

5. Click Base Unlocked.

This button changes to read Unlock Base and the password is now required to unlock this base conﬁ guration ﬁ le. The Xover page will be displayed as View Only until it is unlocked. Any user, even a system designer, cannot adjust the settings unless they ﬁ rst unlock the base conﬁ guration ﬁ le.

Level Limits and Adjust Factory options are locked out in both User and Designer Modes, and the input delay fader is removed when in User Mode.

Save the new base conﬁ guration ﬁ le:

1. Click Label Exit then Module Store/Recall.

2. Click Base Conﬁ guration.

3. Navigate to the desired folder location or create a new folder.

4. Click New Store, enter “Base Conﬁ g Test” and click OK.

The ﬁ le is stored in the folder you navigated to prior to storing and the screen appears. In addition to locking the crossover, HPF/LPF, etc., of a base conﬁ guration ﬁ le, the entire ﬁ le can be protected

from accidental deletion. Secure the base conﬁ guration ﬁ le:

1. Click File Utilities.

2. Select the Base Conﬁ g Test base conﬁ guration ﬁ le from the scroll-bar.

3. Click Read Only. Notice that the Delete button is now disabled for this ﬁ le.

Note: For further protection, base conﬁ guration File Utilities are disabled when in User Mode.

Load the new base conﬁ guration ﬁ le into Module B of the processor:

1. Click File Util EXIT, then click the Module B icon to select it.

2. Select the Base Conﬁ g Test ﬁ le on the scroll-bar and click Recall.

3. Click Yes to the warning message.

All data changed during this tutorial is loaded into Module B, and because the base conﬁ guration was locked, some data is now invisible or protected. Navigate to the various sections of Module B to verify the changes made to the base conﬁ guration ﬁ le.

To Check... Navigate to...

Factory Levels are locked. EQ/Levels -> Levels Tab -> Meter Options – the Adjust

Factory button normally present is not available until the base conﬁ guration ﬁ le is unlocked.

Summary

Page 59

Base conﬁ guration ﬁ les enable low-level security allowing control over individual aspects of the system. The system designer can ﬁ ne tune a speaker conﬁ guration or system EQ and protect the settings by hiding or setting them as view only.

The base conﬁ guration ﬁ les 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 ﬁ ne-tuned by another designer or user.

Security for Module Functions

All settings that can be protected for a base conﬁ guration can also be protected for a Module. Base conﬁ guration settings are overwritten by Module settings, unless access has been restricted in the base conﬁ guration ﬁ le, in which case certain parameters will not be accessible. The base conﬁ guration ﬁ le itself will not be affected by any changes made to a Module after the ﬁ le is loaded.

The Module password is saved with the single module ﬁ le, and is stored when loaded into a processor. This prevents access to certain data stored in the Module ﬁ le, even if you are in Designer Mode in the LP48 Loudspeaker Controller. Using a Module password allows hiding of your custom settings from any user of the LP48.

The following features are available for both base conﬁ guration and module ﬁ les:

• Adjust and lock factory levels

• Adjust and lock access to crossover settings

• Hide unused channels

• Adjust level limits

• Disable individual level faders or entire level sections from other designers (using Level Limits and Module Lock)

Summary

Modules can store and secure all data that a base conﬁ guration can.

Page 61

Security for Group Functions

Groups are used to connect and adjust multiple Modules. Groups cannot be locked or password-protected. Global Access settings also apply to Groups. Security for levels and crossovers is not relevant for Groups.

A Group may contain various 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.

Adjust Factory

A button labeled Adjust Factory is available on the Meter Options menu from the levels page of a Module. When this button is active (orange) a label reading [ADJUST FACTORY] appears at the top of each levels page to conﬁ rm this special mode of operation. Factory levels are not applicable for Groups.

In this mode a different set of ‘factory’ levels are displayed for each level type. These are displayed using the same faders and meters used for the adjustment of user levels; the fader positions and gain values change to indicate the factory level instead of the user level.

Note: The sum of Factory, User, and Group levels are combined to provide the actual total. Factory levels are not included in the total level value, which is shown in brackets in user mode.

The table below shows which level types are available in Adjust Factory mode:

Level Type Available?

Gain Yes Delay Yes Limiter Max RMS Yes Limiter Corner No Limiter Attack and Release No Input Headroom No Output Amp Clip Level Yes

To set factory levels:

1. From the Levels page, click Meter Options, then Adjust Factory.

2. Click Meter Opts EXIT and navigate to the relevant Levels page.

3. Enter the values required using the fader or keyboard entry.

4. Click Meter Options, then Adjust Factory to exit this mode. Note: Factory levels can be hidden from the end user by locking the Module or exiting from Designer Mode.

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, click Meter Options, then click Level Limits.

2. Click Gain/Delay Limits or Limiter/Soft Clamp Limits.

3. Click 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 click OK.

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.

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 ﬁ xed, either lock the Module or base conﬁ guration, or switch to User Mode.

Page 65

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. Set the minimum and maximum values of all inputs/outputs for a particular level type to the same value.

The ﬁ gure above shows an example of identical min/max settings for delay. These settings disable the levels function on the EQ/Levels menu in User Mode or when the module or base conﬁ guration is locked.

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 click Meter Options.

2. Click Label Channel, then click the mute/label button of the relevant channel.

3. Type unused and click OK. The meter and fader will be invisible on the Levels screen. To enable the channel again, change the channel label

to something other than unused.

Creating Descriptions/Assigning Graphics for Module Files

Text ﬁ les (.txt) and bitmap ﬁ les (.bmp) with the same ﬁ lename as a module ﬁ le can be placed in the data/user/ modules directory of your Lake Controller installation. All the Mackie and EAW modules use this method to provide

When a text ﬁ le is present with the same ﬁ lename, the controller displays the text when the module ﬁ le is selected on the Module Store/Recall scroll-bar. When a bitmap ﬁ le is present, the graphic is displayed in place of the default module icon.

Follow the steps below to create and view module ﬁ le descriptions:

1. Store a module with the ﬁ lename example at the module root directory.

2. Minimize the controller and using a text editor (e.g. Microsoft Notepad) create a text ﬁ le containing the

text: ‘Example description for Example Module.’

3. Store this text ﬁ le in the directory:

Program Files\TT24\Data\User\Modules directory as example.txt

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 the ﬁ gure below. Module descriptions can be modiﬁ ed by editing the text ﬁ le, or deleted by deleting the text ﬁ le. Note: Folder descriptions can also be created by placing a text ﬁ le with the same name as the folder in the same

directory as the folder. Note: If bitmap ﬁ les are used to replace the standard module graphics, these must be 24-Bit Windows format

bitmaps of 80x80 pixels maximum dimension. Module name text will overwrite the bottom portion of this 80x80 bitmap.
