1.7 User Responsibility

1.7.1 Mains Connection Grounding
Your apparatus must be connected to a grounded socket outlet.
1.7.2 Speaker Output Hazard on Amplifiers
Amplifiers are capable of producing hazardous output voltages. To avoid electrical shock, do not touch any exposed speaker wiring while the amplifier is operating. The external wiring connected to the speaker terminals shall be installed by a qualified person, or ready-made leads or cords of appropriate capacity shall be used.
As the power output channels on amplifiers produce high voltage, do not connect or disconnect speaker cables when the mains power is on.
1.7.3 Speaker Damage
Amplifier apparatus is very powerful and can be potentially dangerous to both loudspeakers and humans
alike. Many loudspeakers can be easily damaged or destroyed by overpowering them. Always check the speaker’s continuous and peak power capabilities. Although the amplifiers attenuators can be used to reduce the overall gain, an increase of the input signal can result in full output power, which may cause damage to connected speakers.
1.7.4 Maintenance
For safe and reliable operation, the dust filter on should be removed and cleaned regularly to ensure maximum airflow through the device. If the dust filters are not maintained there will be safety risks; for example, high internal temperatures could ignite the dust and start a fire. There is also a risk that the unit will malfunction since it is dependent on constant airflow from front to rear.
If the dust filters are not clean and the unit malfunctions, any resulting problems will not be covered by the warranty.

3. The Flashline System

The Flashline TFS-900 System is a complete, fully integrated, large scale, five-way two-box line array sound reinforcement system. It comprises mid/high and sub-bass loudspeakers, amplification and system control racks, flying hardware, and transport cases in a very powerful and space-efficient format.
The Flashline system is designed to allow integration of systems around the world with guaranteed ‘out of the box’
compatibility.

3.1 TFS-900H mid/high loudspeaker

The TFS-900H is a four-way line array module covering the frequency range above 70Hz and containing three 1” high frequency compression drivers loaded by Dendritic waveguides, two 6.5” high-mid cone transducers loaded by Polyhorns, four 6.5” horn-loaded low-mid cone transducers, and two 12” horn-loaded low frequency transducers.
The rigging hardware is integrated into the end-cheeks on each side of the TFS-900H cabinet, which also provide grab handle positions. Drop links at the front and rear of the box engage in the flygear of the box below it in the array to give a range of inter-cabinet angles from 0° to 5°. TFS-900H cabinets are normally transported four-up on the TFS-DOLLY and can be flown right off the dolly in blocks of four, with the rigging hardware already pre­configured for use. A simple TFS-GRID and TFS-TIP system is used to fly a typical array; no additional external parts are required to fly the system.
The cabinet is finished in black TourTough finish.

CONFIGURED FOR TFS-900H CONFIGURED FOR 4-WAYCONFIGURED FOR TFS-900B/L

4.2 Damping Factor in cable

Turbosound recommends that for large scale PA use the total system damping factor should be 15 or greater. Longer cables will reduce the overall damping factor of the system. In order to keep the damping factor over 15 it will be necessary to increase the impedance of the load to keep the damping factor. Therefore for long runs Turbosound recommends no more than two enclosures per amplifier. Turbosound recommends using 4mm2 cable as standard.

5. System Configurations
5.1 Suggested amplifier loading for the TFS-900H
user manual
Flashline
Each amplifier powers three enclosures. Whilst in theory the amplifier can power four enclosures this presents the bass and low-mid with a 2 ohm load, which does not offer optimum performance.
BASS loading 2.6 ohms LOW loading 2.6 ohms MID loading 4 ohms HIGH loading 6 ohms
Each amplifier is connected to one of the three phases on the power supply. For optimum loading on large systems it is good practice to load all phases equally.
Flashline User Manual
page 15
user manual
Flashline
5.2 Suggested amplifier loading for subwoofers
Each amplifier powers up to six TFS-900B or TFS-900L enclosures. Each NL4 connector can power three subwoofers. Each subwoofer has a drive unit wired to each pair of pins on the NL4 connectors.
Do not use the NL4 and NL8 connections simultaneously on one amplifier.
In this configuration speaker cable lengths should not be greater than 20m due to damping factor considerations.
Each amplifier is connected to one of the three phases on the power supply. For optimum loading on large systems it is good practice to load all phases equally.

5.3 Suggested amplifier loading for subwoofers in cardioid mode
user manual
Each amplifier powers four TFS-900L or TFS-900B enclosures. The first NL4 on each amplifier powers the rear facing cardioid unit, while the second NL4 powers the three forward facing units.
In this configuration speaker cable lengths should not be greater than 20m due to damping factor considerations.
Do not use the NL4 and NL8 connections simultaneously on one amplifier.
Do not use the NL4 and NL8 connections simultaneously on one amplifier.

7. Rigging the Flashline system

7.1 Overview

The rigging system consists of the following main components:
• TFS-GRID – a rectangular box section flying frame that supports a column of up to 20 cabinets
• TFS-TIP – a central bar which provides front and rear pick up points
• TFS-FT900 – the fly trunk houses two TFS-GRID flybars and associated parts such as shackles and locking bolts. It
is designed so as to allow the flybar to be connected and lifted out of the case with minimal manual handling
• Flex Array cabinets can be flown underneath as downfills using the CF-900 conversion frame
• RECLINE laser pointer allows remote monitoring of the vertical inclination of the array

• If the inter-cabinet angles have not already been set during warehouse preparation do this now. Set the angles
between cabinets with the front top pin on each cabinet by lifting the drop link of the cabinet above and inserting the pin into one of the marked holes, reading the required angle settings from your EASE Focus2 prediction. Ensure the pin is engaged in one of the four drop link holes and not in the central slot.

• Check that the rear pins are engaged on both sides of the cabinet. Note: never lift the array without the rear
pins engaged. Regardless of how many people are rigging the array, it is one person’s job to always check that the angles are set identically and correctly and that pins are fully engaged on both sides of each cabinet.
• The first block of four cabinets is now ready to lift. Check that all links are correctly fitted and secure. Take both
motors up together and lift the cluster clear of the TFS-DOLLY. The fronts of the cabinets will now open up as the cluster lifts clear of the TFS-DOLLY depending on the angles set between them, creating a gradual smooth curve to the front of the array.
• Fit the lower front pins on cabinets #1, #2 and #3 into the holes marked LOCK on both sides of the cabinets in
order to lock the array into a rigid structure. Do this now because if left until later it will not be possible to reach them.
• A spanset and shackle can now be attached to the rear of the TFS-GRID flybar to feed the speaker cabling
through, allowing enough length to allow the cables to reach the lowest cabinet in the final cluster.
• Connect the first NL8 cable run to cabinet #1 and link down to the next two cabinets, making a total of three
cabinets on the first NL8 run. Connect the second NL8 cable run to cabinet #4.

• Locate the top rear pins on cabinet #5 in the LOCK/GRID position. Set the angles on cabinets #5, #6, #7 and #8
using the top front pins if these have not been done already. Take both motors up together and lift the second block of cabinets off the TFS-DOLLY. As before the fronts of the cabinets will now open up depending on the angles set between them.
• Fit the remaining lock pins to stabilise the array.
• Continue this procedure until the required number of cabinets are flown.
• Raise the array to the height specified by your EASE Focus2 prediction using a tape measure or laser system to
check the height of the array

• The TFS-DOLLY wheelboards can be stacked using the woodwork rebates provided Fold the TFS-COVERS and
stack them on top of the wheelboards.

7.4 De-rigging the Array

• Taking the cluster down is a simple reversal of the rigging procedure. Bring the cluster down until the bottom
box is approximately a foot off the ground, and take the lock pins out at the front of the lowest four or more boxes (depending on the curvature of the array) to allow the cabinets to close up, and place them in the stow position. Lower the back motor gently to get the bottom box reasonably horizontal.
Make sure you always know the total weight of the cluster. Never put more weight on a rigging point than it is rated for, and always calculate how much weight is on each rigging point.
• Carefully lower the cluster down onto a TFS-DOLLY. Disconnect the top pins from the fourth box.
• Carefully raise the array to free the lower four boxes.
• Ensure the drop link of the bottom box is up and into its locked position. Do not land the cluster on the drop
link or you will bend the rear hinge. Do not leave the front lock pins in for trucking, always put them in the store position.
• Leave both pins in on the rear assembly because it is designed to allow the cabinets to touch each other in a
truck rather than the rigging hardware.
• Having de-rigged each block of cabinets onto a TFS-DOLLY one by one, put the covers on and stow the NL8
links in the cover.
• Finally lower the TFS-GRID flybar into the TFS-FT900 flytrunk in, disconnect the motors and lift the motors to a
safe position above head height.
• Stow the shackles in the trunk, slide the TFS-TIP tipper bar out, put the bolts back in the trunk and replace the
tipper bar in its stowed location.

9. Amplifier Installation

9.1 Unpacking

Carefully open the shipping carton and check for any damage to the device or the supplied accessories. Every Turbosound product is tested and inspected before leaving the factory and should arrive in perfect condition. If any damage is discovered, please notify the shipping company immediately. Only the consignee may initiate a claim with the carrier or their insurers for damage incurred during shipping. Save the carton and packing materials for the carrier’s inspection.
In addition to the 20000DP amplifier, the shipping carton include the following items:
• 20000DP Quick Start & Field Reference Guide
• AC mains lead (power cable) with Neutrik® powerCON® connector
• Rear brackets for additional rack support (pair) along with associated mounting hardware
• Software Installer and Documentation CD-ROM
Please keep the original carton and associated packaging to facilitate shipping of the device should the need arise.

9.2 Mounting

Airflow for cooling the 20000DP is from front panel (intake) to rear panel (exit). Please ensure that no object, such as rack doors or lids are placed at the front or rear of the rack to ensure that airflow is maximized. This device has no top or bottom vents and therefore may be stacked directly on top of each other. Sufficient space should be available at the front of the rack to accommodate the handles, and at the rear to accommodate connectors and cables; allowance must be made for cable or loom bends within a rack.

9.3 Rear Mounting

Two rear support brackets along with associated mounting hardware are included with the 20000DP, as shown in Figure 1; it is recommended that these are used wherever possible. Fit the brackets to the vertical rails at the rear of the rack. Figure 2 and Figure 3 show the fitting options for fixed and removable installation. The support brackets are reversible and may be fitted to point either to the front or rear of the rack; the orientation used depends on the rack depth and position of the rear rack rails. Two mounting methods are possible; note that the method shown in Figure 2 additionally provides extra security against unauthorized removal. For situations where rapid removal and replacement is required, the method shown in Figure 3 should be used.

9.4 Cooling

9.4.1 Overview
The 20000DP uses a forced-air cooling system with airflow from front to rear, allowing high continuous power levels without thermal problems. Front-to-rear airflow is preferable as air at the front of a rack is cooler than that at the rear in nearly all situations; never attempt to reverse the airflow. The operation of the cooling system is dependent on front-to-rear airflow; it will not function effectively with external airflow in the opposite direction.
Make sure an adequate air supply is provided in front of the 20000DP, and that the rear of the amplifier has sufficient space to allow air to escape. If the amplifier is rack-mounted, never operate the unit with any front or rear rack doors or covers in position. It is recommended to keep the ambient temperature around the amplifier as cool as possible. An increased temperature can have a significant negative impact on the expected lifetime on the components inside the amplifier.
Fit solid blanks (not ventilation blanks) to unused rack spaces to ensure effective air circulation. Leaving gaps in between items of equipment degrades the effectiveness of forced-air cooling.
If installing one or more 20000DP amplifier in a rack with other fan-cooled equipment, be sure that all the other equipment also uses front-to-rear airflow for cooling. If this precaution is not observed, there is a risk of overheating, as units with the reverse airflow will be drawing in air which has already been heated by the amplifiers.
9.4.2 Temperature Sensing and Protection
The 20000DP is equipped with a sophisticated temperature sensing system which protects it from any overheating which may occur as a result of inadequate ventilation.

9.5 Operating Voltage

The 20000DP is equipped with a universal power supply operating from 80 to 265 V. Only connect the mains cable (AC cord) to an AC source of the voltage shown on the label. The 20000DP uses primary switching, which means the mains power is rectified on the primary side of the transformer. This makes the power supply insensitive to mains frequency variation, and it will operate normally on line frequencies from 45 to 75 Hz. If the mains plug (AC plug) fitted to the mains cable (AC cord) is not appropriate for your country, it can be removed and a locally-sourced one
fitted instead, observing the color coding in the table below:
PowerCON Pin 230V version 115V version
L Brown Black
N Blue White
E Green/Yellow Green
If you are not 100% confident of your competence to replace the mains plug (AC plug), the task should be carried out by qualified personnel.
Once a suitable AC power supply is connected, the device can be turned on using the front panel power button. When turned on, a diagnostic routine is performed and the power button LED changes from red (Standby) to green (Active).
Flashline User Manual
page 35
user manual
Flashline
In-rush current is controlled and limited during the soft-start sequence. This enables multiple amplifiers on the same AC mains circuit to be turned on simultaneously.

9.6 Grounding

Analog inputs feature Iso-Float™ ground isolation, a technology which combines the benefits of transformer­coupled isolation with the advantages of clean, direct-coupled inputs. The audio converters are galvanically isolated, and not connected to the main ground. High-speed transformers and opto-isolators create a barrier between the device and the outside electrical environment.
The Iso-Float feature is activated by default, but may be disabled via the Lake Controller software, or via the front panel menu.
Use correctly-shielded balanced audio input connections to minimise hum and interference. NEVER disconnect the earth (ground) pin on the mains cable (AC power cord).

10. Product Overview

10.2.1 Connectors
10.2.1.1 Analog Inputs
Analog inputs are available on two standard XLR3F latching connectors. The inputs are electronically balanced and feature Lake Iso-Float circuitry. The impedance is 20 kohms, and the inputs can accept a maximum input level of +26 dBu.
10.2.1.2 Analog Links
Two latching XLR3M connectors are fitted adjacent to the analog input connectors. These are paralleled to the input connectors to provide an unprocessed analog loop-through to feed additional amplifiers, or other equipment.
10.2.1.3 AES3 Input
A latching XLR3F connector is provided which accepts an AES3 digital audio signal. Input impedance is 110 ohms, please ensure that 110 ohm digital audio cables are used; standard XLR microphone cables are rarely suitable for reliable digital audio transmission.
AES3 is a stereo digital format, and therefore both PLM inputs are fed via a single connector. Selection of the analog or digital inputs is made via the front panel display or control software.
10.2.1.4 AES3 Link
A latching XLR3M connector is fitted adjacent to the AES3 input connector. This is paralleled to the input connector to provide an unprocessed AES3 loop-thru to feed further amplifiers, or other equipment. An AES3 110 ohm termination load is enabled by default when the amplifier is the last unit connected within an AES3 daisy-chained system. The termination may be disabled, if desired, via the front panel menu and within the Lake Controller
software.
10.2.1.5 SpeakON Connectors
The 20000DP is provided with Neutrik speakON® power output connectors, and allows for Bridge Mode operation which is activated from the Lake Controller software. Please refer to the Lake Controller Operation Manual and the 20000DP Operation Manual for further information on Bridge Mode.
The power outputs are simultaneously available on a single 8-pole speakON connector, and on two 4-pole speakON connectors. The two 4-pole connectors carry the outputs of channels 1 & 2 and 3 & 4 respectively.
Bridge Mode can be enabled via the Lake Controller software, please refer to the Lake Controller Operation Manual and to section 8.1.2 of this Operation Manual for further details on standard and Bridge Mode wiring for speakON
connectors.
10.2.1.6 Primary Network Connector
The primary Neutrik RJ45 etherCON® con nection provides integration into an Ethernet control network which may include other Lake Processors and the Lake Controller software. Network connection permits full control of all functions along with real-time metering from a remote position. This device supports the Dante audio networking protocol, which allows transmission of multichannel, high-definition digital audio over the same Ethernet connection.
Flashline User Manual
page 39
user manual
Flashline
Use the primary connector when using a star network topology, consisting of individual Cat-5e connections between the devices and an Ethernet switch. Alternatively this connection can be used to daisy chain directly to another Lake Processor. The daisy chain topology should not be used with Dante.
For a technical reference of the Ethernet Port, please refer to the 20000DP Operation Manual. Additional information is available in the Lake Network Configuration Guide.
The Ethernet ports operate at the Ethernet data rate of 100 Mbps, and allow straight or crossed network cables. Two LEDs above each port indicate valid network connection (LINK) and network activity (ACT).
10.2.1.7 Secondary Connector
The secondary network connector can be used to daisy-chain multiple 20000DPs, LM 26 and legacy Lake devices. Alternatively, a Dante dual-network topology can be created by connecting all secondary network connectors to a separate Ethernet switch, ensuring full redundancy in the event of a network component failure.

If the required audio signal is not passing correctly, verify the connection, mute and volume settings at all seven stages.

11.3 Power Output Section: Limiting and Sensitivity

The Current Peak Limiter (CPL) dynamically limits the drive to the power stage based on three parameters: sensed output current level, feedback from the output stage, and sensed voltage clip from the ISVPL. This ensures that power output is maintained within the design limits of the amplifier.
The adjustable Inter-Sample Voltage Peak Limiter (ISVPL) sets the 20000DP’s maximum output voltage and therefore also the maximum output power. The ISVPL setting is made via MENU > MODULE > LIMITERS > ISVPL, and can also be set from the Lake Controller software.
The sophisticated output section monitors faults and generates warnings when appropriate; warnings are displayed on the front panel of the 20000DP and also sent as messages over the control network. In the rare event that maximum ratings are significantly exceeded, the amplifier will shut down until the condition has been rectified or the incorrect setting has been readjusted. Sensing circuits also transmit local output power stage temperature, processor card temperature, and PSU temperature to the appropriate protection circuits. The table below lists analog input sensitivity in dBu and Vrms for various Amp Gain settings and maximum/minimum ISVPL settings, assuming an analog input headroom of 26 dBu.

11.4 Lake Processing and Control

As outlined in section 2.2.3, this device integrates seamlessly into the Lake Processing environment, providing all features, functionality and connectivity associated with all Lake Processors. The internal Lake Processing includes programmable crossovers, EQ, dynamics and other functions, and can be fully controlled via the supplied Lake Controller software. Additionally, many functions can be controlled or accessed directly via the front panel.
The Lake Controller Operation Manual and Lake Network Configuration Guide are supplied on the accompanying CD-ROM and additional documentation is available from the Start Menu after software installation.

11.5 Modules and Frames

11.5.1 Overview
A Frame represents one physical Lake Processor (e.g. a 20000DP). A maximum of two Modules are contained within each Frame; these are referred to as Module A and Module B. The number of Modules shown in a given Frame is dependent upon the signal processing configuration of that Frame.
Each Module can be configured as a Classic Crossover (Bessel, Butterworth, Linkwitz-Riley), as a Linear Phase Crossover, or as multiple full bandwidth Auxiliary Outputs. The default configuration is 2 x 2-Auxiliary Output Modules, providing a total of four module outputs.

11.6 LoadLibrary™ and Fingerprints

In addition to the standard loudspeaker presets (Module files), the Lake Controller also includes a set of enhanced Module files specifically for use with the 20000DP.
These supplementary Module files, known as the LoadLibrary, incorporate both Lake DSP parameters along with 20000DP specific data; LoadLibrary Module files include parameter settings for the 20000DP’s Amplifier Gain and ISVPL limiter. Additionally, LoadLibrary loudspeaker types may also include data relating to the electrical characteristics of a particular loudspeaker.
Flashline User Manual
page 43
user manual
Flashline
Electrical characteristic data is used to enable load verification (LoadSmart) and monitoring facilities (SpeakerSafe) to be performed on the 20000DP. This data set is termed a Fingerprint. When a 20000DP-specific loudspeaker type is loaded, its Fingerprint load characteristics are included. These load characteristics are stored in a file with a “.mdl” suffix and are loaded simultaneously with the module file.
LoadLibrary Modules and standard Module files are cross-compatible, although when a LoadLibrary Module is loaded into a legacy Lake product the extra data within it is ignored.

11.7 Super Modules

Super Modules allow control of multiple Modules of the same type, distributed across multiple Frames, as a single entity within the Lake Controller software. A change made in the Super Module is replicated across all assigned Modules, resulting in improved efficiency in system configuration and a reduction of on-screen icons within the Lake Controller software.
The key benefit of this feature is the ability to connect and control crossovers, levels and EQ across multiple hardware devices simultaneously from the Lake Controller. For example, one device may be driving sub and low­frequency speakers, while another device controls mid-range and hi-frequency drivers. Using a single adjustment the crossover points between the two devices can be changed simultaneously.
Please refer to the Lake Controller Operation Manual for further information regarding Super Modules.
11.8 Loudspeaker Crossover Configuration Overview
The Lake Processing system may be configured with up to two inputs and up to six Module outputs, although the number of power outputs will be either two or four depending on the PLM model being used. To make use of the extra processing channels, multiple hardware devices may be connected together using the Super Module feature as summarized in section 5.3.3.
Each set of processing elements is referred to as a Module and can be configured as crossovers, full bandwidth auxiliary outputs, or a combination of the two. The relationship between inputs and outputs is defined via the Lake Controller or via the front panel Input Config Menu.
The Lake Processing system provides two distinct categories of crossovers:
• Infinite Impulse Response filters (IIR) such as the classic Bessel, Butterworth or Linkwitz-Riley types; these are
available with slopes ranging from 6 dB/octave to 48 dB/octave.
• Finite Impulse Response filters (FIR) providing zero phase shift with steep transition slopes at the crossover
frequencies. These are also referred to as Linear Phase Crossovers.

11.9 Files and Presets

The Lake system provides various methods for storing and recalling Module, Frame, or system-wide data. A overview is provided below; for further information please refer to the Lake Controller Operation Manual.
11.9.1 Module, System and Sub-System Configuration Files
Module, System and Sub-System Configuration files are stored on the Lake Controller PC, and data is passed across the network when recalling or storing these type of files.
Flashline User Manual page 44
user manual
Flashline
• A Module file is the smallest set of data that can be stored and recalled; it contains crossover, gain, delay, and
limiter information for an individual loudspeaker. A Module file may be recalled into other Lake devices. It is not possible to store a Module File directly on the hardware device.
• A System or Sub-System Configuration File contains a set of Module file information in addition to Frame related
information such as I/O routing, along with Group control information.
11.9.2 Frame and System Presets
This device allows the complete processor configuration to be stored as a Frame Preset on the hardware unit itself. Presets can be recalled via the front panel (please refer to section 7.11.7) or via the Lake Controller software (please refer to the Lake Controller Operation Manual).
A maximum of 100 Frame Presets can be stored on this device. The data within a Frame Preset includes the configurations of both Modules in the Frame, including all levels, crossover, EQ, input mixer, output routing, and all other Module, Frame and Group parameters. As Frame Presets are stored in the device, complete processor configurations may be recalled without the need to connect the device to a PC.
Using the System Presets function in the Lake Controller, entire system configurations can be stored and recalled across a network of LM 26, PLM, Mesa Quad EQ, Contour Pro 26, and Dolby Lake Processors. This enables fast retrieval and switching of entire system configurations as minimal data is being sent between the Controller and Processors.

This device provides control, monitoring and digital audio functionality via an Ethernet network. For further information on the setup and configuration of an Ethernet network, please refer to the Lake Controller Operation Manual and the Lake Network Configuration Guide.

12.4 Gain Structure

The 20000DP architecture provides gain adjustments at various points in the signal path and therefore, various places for muting and level adjustment. Each mute or gain adjustment point serves a different purpose.
Detailed information on signal flow and gain structure is available in the 20000DP Operation Manual. The signal flow diagrams in chapter 5 (Figure 5-1 and Figure 5-2) are useful signal path references, and the following sections describe the various adjustment points, all of which are available via the Lake Controller software.
12.4.1 Input Headroom (Analog Inputs Only)
Input Headroom should be set to 12 dBu if the source can be limited to 12 dBu; otherwise it should be set to 26 dBu. This setting does not affect the other gain stages, or the overall noise floor; it allows control of the appropriate headroom at the input stage only.
12.4.2 Input Mixer
Input Mixer gains can remain at 0.00 dB for most configurations; if only one input channel is used per Module, the other can be set to -INF.
12.4.3 Module Input Gain
Input Gain is used to adjust the level between different speaker cabinets in the system. This gain can remain at 0.00 dB unless a lower level is required for the cabinet/s driven by this Module.
12.4.4 Module Output Gain (Levels)
Flashline User Manual
page 47
user manual
Flashline
Factory and User Gain are provided for each Module output. These two stages provide a level of security and control for the system designer (Factory) and a further level of adjustment for the user (User), both of which combine to balance the level between frequency bands in a multi-way crossover.
Generally, output gain values are configured within a Module / loudspeaker preset file and should not need to be adjusted further.
12.4.5 Attenuator
An attenuator gain adjustment is provided for each power output channel in the 20000DP. This control replaces the traditional volume control found on conventional amplifiers and should typically be left at 0 dB during use.
12.4.6 Amp Gain
The Amp Gain corresponds to the gain adjustment in a conventional separate loudspeaker processor and amplifier system. When using a pre-defined Module loudspeaker preset file, the Amp Gain settings will normally remain as defined in the file. The limiter and output gain settings of the Module were configured with this gain setting and will not be automatically compensated if changes are made. This configuration scheme, though unusual, allows for compatibility with legacy Dolby / Lake products.

12.5 Gain / Level Optimization

12.5.1 Maximize Volume Capability
To maximize the volume capability of the device, ensure there is sufficient headroom in the signal path to avoid clipping before the limiters engage. It must be possible to achieve enough gain through the device to engage the limiters and realize a high average SPL. As an optimal setting, allow for a headroom of 10 dB or more for all channels; the simplest way to accomplish this is to increase the Module input gain.
12.5.2 Minimize Noise
To help provide the best volume to noise ratio, use an AES or Dante digital input signal wherever possible. If using analog inputs, ensure that unused or unnecessarily high headroom is not introduced at the input to the device. If full or high average power is not required, the Module input gain may be reduced.
