6. Installation
6.2. Mounting
D Series is made for mounting in 19 inch racks. Four screw holes are available for attachment of the amplifier to the racks front rack rail. This device has no top or bottom vents; therefore, units may be stacked directly on top of one another. Sufficient space should be available at the rear to accommodate connectors and cables. In addition, allowance must be made for cable or loom bends within a rack.
6.2.1. Rear Mounting
Two rear support brackets, along with associated mounting hardware, are included with the D Series device. It is strongly recommended that these are used wherever possible. Fit the brackets to the vertical rails at the rear of the rack. The following diagrams 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 proper orientation depends on the rack depth and position of the rear rack rails.

6. Installation
6.2.2. Mounting front grille
The front grille is shipped on top of the amplifier inside the box to protect it during shipping. The front grille adheres to the amplifier with magnets. Hold the front grille with your fingers in each of the side cutouts and slide it gently into place straight from the front.
NOTE: Always ensure the dust filters behind the detachable front panel are clean to ensure maximum possible airflow. The exterior front panel is held in place by powerful magnets but is easy to detach by using your fingers in the openings at the each side. To clean the foam filter, detach it from the exterior front and gently use a vacuum cleaner or gently shake it. Remount with the opposite procedure. Never operate the amplifier without the dust filter installed.
6.3. Cooling and fan operation
D Series devices use a forcedair cooling system with airflow from front to rear, allowing high continuous power levels without thermal problems. To facilitate maximum air flow, ensure that no objects such as rack doors or lids are placed at the front or rear of the rack. Never attempt to reverse the airflow. Make sure an adequate air supply is provided in front of the D Series device, and that the rear of the device has sufficient space to allow air to escape. It is recommended to keep the ambient temperature around the device as cool as possible. An increased temperature can have a significant negative impact on the expected lifetime on the components inside the D Series device.
NOTE: 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 forcedair cooling.
If installing one or more D Series devices in a rack with other fancooled equipment, confirm that all other equipment also uses fronttorear 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 D Series devices.
The D Series device is equipped with a sophisticated temperature sensing system which protects it from any overheating which may occur as a result of inadequate ventilation.
6.4. Operating voltage
D Series has a universal power supply and its mains nominal and operating voltages are specified in the Technical Specifications. D Series can be ordered with a variety of mains plugs. 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 locallysourced one fitted instead. 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.
NOTE: Inrush current is controlled and limited during the softstart sequence. This enables multiple D Series Devices on the same AC mains circuit to be turned on simultaneously.

6.4.1. Low voltage country considerations
Although the D Series has a wide range of operating mains voltage, some considerations can be applicable for low voltage regions. D Series performs well throughout the specified nominal voltage range but has slightly better efficiency at higher voltages. For regions with nominal voltage below 140 V, one could consider connecting the amplifier in a three phase delta or two phase split-phase configuration, especially applicable for the bigger models, (D200, D120 and D80).

NOTE: Following connections applicable only for resulting voltage inside the amplifiers nominal voltage range.

Connecting the amplifier in three phase delta configuration In threephase configuration where the phases are 120 degrees apart, one can connect three balanced loads in a delta configuration. The connection is made between the phases instead of between the neutral and a phase.

11.1. Operation precautions
Make sure that the Standby button on the unit's front panel is either unlit (OFF), or red (STANDBY), before making any input or output connections. Ensure the AC voltage is within the range printed on the label adjacent to the AC mains connector. Ensure no input signal is present when powering on the unit to reduce the risk of any inadvertent bursts of high level audio.

Rational Power ManagementTM (RPM) is a unique Lab.gruppen feature that allows for flexible allocation of power across channels of a D Series unit. Power that is not used by one output channel is free for use by another output channel with greater demands. Unique to this series is that all models in the range have amplifier channels that can produce higher outputs than the average 25% of the total power, see the Technical Specifications for the maximum single channel power capacity. RPM automatically allocates power up to the total limits of the specific amplifier model and helps minimize unused power in the installation.

21 D SERIES Lake Operation Manual rev 3.0.1

11. Operation and performance
11.3.1. InterSample Voltage Peak Limiter (ISVPL)
The ISVPL is a high quality voltage limiter that can deliver seamless limitation to any desired level. It ensures that the voltage at the output terminals never exceeds the defined threshold. It operates on these principles: · The signal is delayed slightly to allow the ISVPL to lookahead and reduce the gain before voltage in excess
of the threshold can appear at the output. This results in zero voltage overshoot at the output with a rounded limitation up to the threshold. · The amplitude of the output signal between digital samples is predicted which permits the ISVPL to respond to analog peaks that may occur at the digital to analog converter. · The release time of gain reduction is adaptive depending on the dynamics of the signal. It is possible to select different ISVPL profiles for limiting optimization for a specific frequency band and personal preference. The profiles are divided into two categories, with one category optimized for low distortion and the other focusing on producing high sound pressure level (SPL). Within each category there are profiles optimized for the different frequency bands.
11.3.1.1. Low Distortion Profiles
· Universal The universal profile is a soft limiter that can be used for all frequencies and is conservative in its action upon VCL and CPL.
· Sub/LF The Sub/LF profile is tuned for frequency bands below 600 Hz. It has longer attack and release times and is less conservative when it comes to acting upon VCL and CPL.
11.3.1.2. High SPL Profiles
High SPL profiles do not use the adaptive release time feature. High SPL profiles optimized for high frequencies use less of the lookahead delay peakrounding feature; this feature is used most in the Sub profile and least the HF profile.
· Sub The Sub profile is optimized for frequencies between 20 200 Hz · LF The LF profile is optimized for frequencies between 20 1200 Hz · MF The MF profile is optimized for frequencies between 300 6000 Hz · HF The HF profile is optimized for frequencies above 1 kHz
11.3.1.3. ISVPL Voltage Settings
The ISVPL threshold may be set at any level between 17.8 V and 600 V in the Lake Controller software. For further details, please refer to the Lake Controller User Manual.
Lakeenabled amplifier devices (D Series Lake, PLM+, PLM) that have a smaller peak output voltage capability still allow ISVPL speaker threshold settings up to 600 V. When a threshold is set above the current maximum capability of a power output channel, the actual ISVPL will automatically be set to the maximum ISVPL for that channel. Therefore, the ISVPL threshold can be set at the Module for the speaker's maximum capability, and the Module file remains crosscompatible with all Lakeenabled amplifier devices.
Table 11.3 shows the theoretical maximum output power based on only the load impedance and the ISVPL setting. See the Technical Specifications, or use CAFÉ, to find the available power for a specific amplifier and load.

11.3.2. Current Peak Limiter (CPL)
The output Current Peak Limiter (CPL) ensures that the power output section will not be damaged by forcing it to deliver current levels at the outputs that exceed the maximum current ratings of the output transistors. The CPL keeps the output transistors within their Safe Operating Area (SOA). The CPL is nonadjustable.
This condition indicates an attempt to draw excessive current at the output. The output is attenuated until the output current falls below the maximum current rating. Limiting is performed by the ISVPL limiter in conjunction with the selected ISVPL profile.
CPL activity is shown by amber or red indication on Amp LED of the affected output channel and a corresponding text description in Lake Controller and CAFÉ software programs. Refer to Section 14.1 for more information on warnings and faults.

NOTE: If excessive current is indicated, check the output cables and examine the loudspeaker. If impedance appears normal, you may rectify the condition by altering the ISVPL settings or lowering input levels. CPL indication can be triggered by excessively low load impedance, possibly the result of too many loudspeaker cabinets connected in parallel.
11.3.3. Power Average Limiter (PAL)
The Power Average Limiter Active warning (PAL Active) will be displayed when the power supply is operating at the maximum average input power allowed for the PSU design. When this warning is displayed, gain limiting is being applied to the signal by a lowering of the ISVPL threshold.

11.3.5. Under Voltage Limiter (UVLTM)
The larger D Series devices (not D 20:4L and D 10:4L) are equipped with an under voltage limiter. With multiple, powerful devices on a mains distribution line, heavy current loads risk the reduction of voltage below that required for devices to function. The UVL reduces the mains current draw when voltage drops below 80 V. The amount of reduction applied increases as mains voltage drops towards 65 V; at 65 V the power supply is

11.3.6. Current Average Limiter (CALTM)
The Current Average Limiter (CAL) monitors the RMS current drawn from each power output channel to ensure that the power output stages are not overloaded. When activated, it regulates the current to a safe level to protect the channel. The CAL should not be activated in normal usage. If activated, this is shown by amber or red indication on the Amp LED of the affected output channel and a corresponding text description in Lake Controller and CAFÉ software programs. Refer to Section 14.1 for more information on warnings and faults

11. Operation and performance
NOTE: For Slimeline models, to optimize the CAL's behavior when playing into a low impedance load, manually set the desired ISVPL to reflect the real peak voltage output to allow for a higher average current.
11.3.7. Voltage Clip Limiter (VCL)
If current draw from the unit's power supply is too high, the PSU's regulation capability may be exceeded and the internal voltage rails may drop and cause clipping. If this occurs, the VCL acts rapidly to prevent clipping on the subsequent peaks. Limiting is performed by the ISVPL limite Indication of this condition is shown on the output LEDs. Refer to Section 14.1 for more information on warnings and faults.
11.3.8. Temperature Protection
D Series devices are equipped with a sophisticated temperature sensing system that provides protection from overheating which may occur as a result of inadequate ventilation or excessive power output. Thermal measurements are made at several points within each power output channel along with measurements in operate continuously, with the highest possible output, and prevent shutting down. If temperature in any area reaches a critical level, a warning is displayed. The warning is issued at approximately 80% of the maximum allowable temperature. If the temperature continues to increase, a limiter (ATL or PTL) is engaged that limits signal peaks to reduce further heat accumulation. Limiting is accomplished by gradual reduction of the ISVPL thresholds. In the extreme case where the limiter cannot reduce heat accumulation and temperature reaches a dangerous level, a fault is displayed and audio is muted. Each power output channel, the power supply, and DSP area have separate indications. For all temperature faults, temperature monitoring will continue at 0.5 second intervals, with the output remaining muted. When the area has cooled below the dangerous threshold, the fault condition is cleared and audio is restored.
11.3.8.1. Power Output Channels
A power output channel temperature warning or fault is indicated by the Amp LED for that channel and the Temp LED for the frame. · A warning is indicated by a static amber LED · · A fault is indicated with a static red LED An event report is sent to the Lake Controller software for both the warning and the fault. If a temperature fault condition arises on a power channel, the output of that channel will be muted.
25 D SERIES Lake Operation Manual rev 3.0.1

11. Operation and performance
If the amplifier output channel temperature keeps rising after reaching the temperature warning threshold, the Amp channel Temperature Limiter (ATL) will engage at approximately 95% of the maximum allowable temperature. When ATL is engaged, it will try to reduce the power output to avoid that the amp channel goes into temp fault, i.e. muting. Limiting is removed when temperature falls below the ATL threshold.
11.3.8.2. Power Supply / DSP
A power supply (PSU) or DSP temperature warning or fault is indicated by the Temp LED. · A warning is indicated by static amber LEDs · Power supply Temperature Limit (PTL) is indicated by an amber LED · A fault is indicated with static red LEDs
If the power supply temperature keeps rising after reaching the temperature warning threshold, the Power supply Temperature Limiter (PTL) will engage at approximately 95% of the maximum allowable temperature. When PTL is engaged, it will try to reduce the total amplifier output power to avoid that the power supply goes into temp fault, i.e. muting of all channels. Limiting is removed when the temperature falls below the PTL threshold.
11.3.9. DC Protection
The DC protection is implemented, individually, on each power output to prevent damage to connected loudspeakers or any D Series components. DC present at the output will cause the unit's power output module breaker to blow, causing a permanent hardware fault that prevents signal throughput. In this instance the channel's Amp LED will illuminate red and a service channel fault will be registered in the Lake Controller and CAFÉ status views (D200, D120, D80 only). For the D40, D20 and D10, no audio will be heard from the outputs.
NOTE: A blown breaker in the power output module is not a user serviceable fault condition and the unit should be returned for repair.
11.3.10. VHF Protection
The D Series includes protection circuits that detect Very High Frequency (VHF) content in the input signal. The detection is amplitude, frequency and timedependent. It is initiated from 10 kHz upwards and, if continuous VHF signals are detected above the threshold for more than the attack time, the output for a D200, D120 and D80 will attenuate the gain until the signal is below the VHF threshold. When this is done, VHF Warning is displayed. If the signal is above the VHF threshold and the maximum of -12 dB of gain reduction is not enough to take the signal below the VHF threshold, the signal will mute after 15 seconds, and retest the signal after 6 seconds. Note that the D40, D20 and D10 will go directly to mute upon VHF detection.
normal operation.
This protection system recognizes only continuous VHF signals at high levels that will not appear in speech or music. Any such content can therefore be considered as a fault condition. VHF protection is essential to avoid damage to HF drivers. VHF protection is dependent on a combination of output power level and frequency. Figure 11.4 shows a decreasing power threshold, from approximately 10 kHz upwards, which illustrates increasing sensitivity of the protection system with frequency. When continuous output power above the threshold line is detected, VHF protection becomes active.

11.3.11. Short Circuit Protection
A low impedance or short circuit at the power output terminals is detected when the output current is high (Current Peak Limiter is active) and, simultaneously, the peak output voltage is below a predetermined threshold. When this situation occurs, the output stage is muted to protect it from damage.

Operation of the short circuit protection system is indicated by Amp channel LED showing steady red and a corresponding text description will register in Lake Controller and CAFÉ software programs. Refer to Section 14.1 for more information on warnings and faults.

Should any of these fail, the power supply will shut down to prevent damage or limit severity of the failure. If the power supply shuts down audio will be muted. Power supply faults, or power supply needs service faults, are indicated by a red LED and associated error messages registered in Lake Controller and CAFÉ software programs. In the extreme event of simultaneous low mains voltage supply and high power demand, the amount of incoming

28 D SERIES Lake Operation Manual rev 3.0.1

11. Operation and performance
D Series features a universal power supply with power factor correction (PFC). The device can accept any mains voltage, from 65 V to 265 V, allowing it to function worldwide in many different configurations. The PFC reduces current peaks on the lines and reduces the requirements placed on the mains distribution system. D Series units offer an unparalleled power factor extremely close to one.
11.4.1. Low Inrush Current
High power amplifiers with inadequate inrush current limiting can draw considerable current from the mains at turnon, sometimes tripping a fastacting mains breaker. The D Series, however, has very low inrush current to prevent tripping of breakers. Several units can, under normal conditions, be powered up simultaneously. If you do experience problems powering up multiple units simultaneously, they must either be turned on manually in an ordered manner, or sequenced remotely using the Lake Controller software's Global Control feature. Alternatively, the capacity of the mains supply should be increased.
NOTE: If insufficient power is available to allow simultaneous powerup, then there is probably insufficient capacity for full power output during operation. It is recommended that additional capacity is added to the mains power distribution system.
11.4.2. Adaptive rail control
The D Series slimline models have Adaptive rail control available in Performance (default) and Green mode. In Green mode, this feature further increase the slimline models green credentials by lowering the idle consumption. This is achieved by lowering power supply's supply voltage, to the

NOTE: There is no Auto Power On feature on the return of signal, the device will need to be actively turned on after entering the standby mode via the Auto Power Down feature. This can be done from the network via the Lake Controller or the 3rd party protocol or via the front panel button.

11.6. LoadPilot Load Monitoring
11.6.1. Introduction
LoadPilot is a feature in D Series amplifiers that can continually monitor the integrity of loudspeakers and cables connected to the outputs to ensure that they are functioning properly and free from major anomalies or faults. By implementing LoadPilot, systems incorporating D Series amplifiers can be certified in compliance with voice evacuation standards such as EN5416 and NFPA72.
LoadPilot functions by automatically superimposing lowlevel pilot tones on the input signal (if any present) to the amplifier. One tone is below the range of human hearing (approximately 1020 Hz) and the other above (24 kHz), so the activity of LoadPilot is inaudible regardless of whether the system is currently reproducing program content. Highresolution current sensing on the outputs can calculate the impedance of the load at the frequency of the tones. Hence a stable measurement of the impedance of the load can be obtained and potential anomalies or faults can be detected that would indicate impaired loudspeaker function or total inoperability due to failure of the loudspeaker or faults in connected wiring. The superimposition of pilot tones and analysis is interleaved across the amplifier's output channels with a maximum total cycle time of around 20 seconds.
LoadPilot is implemented and configured in the CAFÉ software. Monitoring status and fault indication are displayed on the front panel and both in CAFÉ and Lake Controller.
LoadPilot may be configured with the automatic calibration or through a manual advanced mode, depending on monitoring requirements and characteristics of the connected loudspeaker loads.
11.6.2. Automatic calibration 11.6.2.1. Functional description
Automatic calibration is suitable for the following applications and requirements for error detection: · If one or two lowimpedance loudspeakers are connected; if two in parallel is default, it will warn if one is
missing. · If there are one or two "spurs" with 70V loudspeakers connected; if two in parallel is default, it will warn if one
is missing. · If there is a short circuit in the load. · If there is an open circuit (all loudspeakers missing). · For passive 2 and 3way loudspeakers, if one or two LF drivers are connected and working; if two in parallel
is default, it will warn if one is missing. · For some passive 2way designs, if one HF driver is disconnected. (However, with some loudspeakers the
HF impedance is dominated by a passive component i.e. crossover filter and the anomaly will not be detected.)
NOTE: LoadPilot is enabled only when the amplifier is On. It does not function while the amplifier is in Standby.
30 D SERIES Lake Operation Manual rev 3.0.1

11. Operation and performance
11.6.3. Manual configuration 11.6.3.1. Functional description
Manual configuration can be used in special cases where proper functioning requires setting of custom measurement frequencies, custom measurement levels, custom warning thresholds, or combinations of the three. Manual configuration addresses the following issues:
Speakers with non stable impedance For the LoadPilot feature to function the load itself needs to have a stable impedance at the frequency of the tone. Resonances in the speaker or other non linear phenomenons can make the impedance at a certain frequency unstable. Stability needs to be verified by examining the impedance response to make sure it is relatively flat at the tone frequencies and by verifying LoadPilot readings when playing signal through the speaker at the most extreme expected level. The frequency of the pilot tones can be changed within certain ranges and a tone can be disabled. If a frequency where the speaker is stable can not be found one tone can be disabled and LoadPilot relies solely on the remaining tone.
High noise levels To obtain accurate impedance measurements, it is necessary to drive a current sufficiently above the noise floor. However, it is important to keep the level low in order to prevent audible artifacts from cone travel. At very high impedances, the drive current may be insufficient. In the automatic mode, level is set around 60 mV which produces usable results for impedance up to 660 ohms.
Inductance in loudspeaker cables Loudspeaker cable inductance at higher frequencies is very high relative to passive resistance, and the inductance increases linearly with length. Consequently, monitoring at the 24 kHz pilot tone frequency can be problematic with very long cables. The automatic mode will estimate cable impedance for 24 kHz and allow it to be used as long as it is less than 33% of total impedance presented by the load and as long as the total impedance is below about 440 ohms.
DC blocking capacitors in loudspeakers Some loudspeakers incorporate a capacitor designed to block damaging voltages at very low frequencies. This may inhibit accurate measurements when using the 10 Hz pilot tone. In automatic mode, LoadPilot will disable the 10 Hz tone if total impedance is above about 440 ohms.
Constant voltage loudspeakers Loudspeakers driven via transformers in 70V/100V solutions are more likely to exhibit wide variations in measured impedance as music and/or pilot tones are reproduced by the system. Also, most constant voltage systems operate more than two loudspeakers in parallel. Therefore, in addition to manual configuration of LoadPilot, additional step may be required. These include:
· Insertion of a series capacitor in each loudspeaker to block the 10 Hz LF tone This will defeat measuring the loudspeakers with the LF tone, but will allow the LF tone to propagate through the entire cable run.
· Insertion of EOL (endofline) resistors This enables LoadPilot to detect cable faults in a spur of the system. · Insertion of EOL (endofline) inductor This is not mandatory, but it will avoid the loss of level at mid and high
frequencies due to the EOL resistor.
NOTE: Manual configuration of LoadPilot is implemented in CAFÉ versions 1.1.0. and later. For detailed information on manual configuration of LoadPilot, please refer to the integrated guide in the software program and to the CAFÉ Coach videos posted on the Lab.gruppen web site and on the Lab.gruppen channel on YouTube.

11.6.4. Indication
The LoadPilot feature constantly monitors the impedances at the two given pilot tone frequencies and compares to the measured thresholds. The following faults and warnings can be triggered.
· Speaker shorted warning Both tones below lower threshold. Corresponds to a distant short circuit that can either be in the cabling or in the speaker.
· Speaker damaged warning One of the tones is below or above thresholds. Corresponds to an unexpected impedance deviation of one of the tones, most likely a damage to the speaker.
· Under speaker count warning Both tones above upper threshold. Corresponds to an impedance increase across the impedance response and most likely a loss of speaker(s) in a parallel speaker connection.
· No load fault At least one tone above measurable area or significantly above upper threshold. Most likely corresponding to loss of the load.
· Short circuit fault LoadPilot analysis below short circuit threshold.

12.4. Loudspeaker Processor Overview
The Lake Processing system within D Series Lake devices may be configured with up to four processing Modules containing a total of up to twelve processing Module outputs that can be routed to any of the four power output channels. 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.
The Lake Processing system provides two distinct categories of crossovers: · Infinite Impulse Response filters (IIR) such as the classic Bessel, Butterworth or LinkwitzRiley 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.

12.6. Frame and System Presets
The entire processor configuration can be stored as a Frame Preset on this hardware device. Presets can be recalled) via the Lake Controller software or Preset Manager utility; presets can be stored using the Lake Controller software or Preset Manager utility. A maximum of 100 Frame Presets can be stored on this device. The data within a Frame Preset encompasses the configurations of all Modules in the Frame, including levels, crossover, EQ, input mixer, routing, and all other parameters. As Frame Presets are stored in the hardware device, recall is available without using a PC.
33 D SERIES Lake Operation Manual rev 3.0.1

13. System configuration tutorial
Using the System Presets function in the Lake Controller, entire system configurations can be stored and recalled across a network of Lake devices, including D Series Lake, LM, PLM and PLM+ Series devices. This enables fast retrieval and switching of entire system configurations as minimal data is being sent between the Controller and Processors.
13. System configuration tutorial
This section will describe how to get started with associated software and set up a basic system for operation.
13.1. Network setup
13.1.1. Network connections/topology
Each frame has two network ports; a primary and a secondary. See the below diagram for a typical network topology using the primary ports. By default, the secondary ports are configured in dual redundancy mode to support a second redundant network. The alternate configuration for the two ports is a switch mode which allows daisychaining devices in a single network. Daisy chain mode is not recommended for more than a few devices, and for not more than two if running Dante audio along with control data.

Alternate configurations would be DHCP for a managed network or fixed IP. To connect to the secondary network in dual redundancy mode the computer shall be configured with an IP address in the 172.31.0.0 172.31.255.255.
13.2. Software installation and firmware update
13.2.1. Lake Controller software suite
1. The Lake controller software suite includes the Lake controller and accompanying utilities: Lake LoadLibrary, Dante discovery services and documentation. Download the Lake Controller installation from www.labgruppen.com.
2. Execute the installer and follow the onscreen instructions. This is a typical software installation where the default settings are acceptable for the vast majority of users.
13.2.2. CAFÉ software
1. The CAFÉ software is available as a separate installer on www.labgruppen.com. 2. Execute the installer and follow the onscreen instructions. This is a typical software installation where the
default settings are acceptable for the vast majority of users.
13.2.3. Firmware update
The latest firmware for the product is included in the Lake controller installation. It is likely that firmware installed on the new product is older and requires updating.
1. Make sure all frames are powered on and connected through a wired network. 2. Launch the Lake firmware update utility LakeUpdate.exe. 3. Select the appropriate product range. 4. If more than one network adapter is enabled, a prompt will appear requiring selection of the adapter connected
to the frames. 5. If prompted, allow the application access through the Firewall. 6. Latest firmware is preselected. 7. Discovered frames are listed. Tap Select Old and Update to initiate firmware update of all outdated frames.
Frames already up to date will not be selected. 8. Read warning message and tap OK. 9. Wait for all updates to be completed. A wait indication will display on the unit(s) during updating. 10. Follow the on screen instructions. Amplifiers with firmware associated with Lake Controller 6.5.0 or later will
automatically power cycle the mains power, whereas amplifiers with older firmware will display a message that a manual power cycle is required. (Note: A manual power cycle requires the mains plug to be completely removed, the standby button does not complete the firmware update.) 11. If internal updates are needed, these will be performed by the frame after the power cycle. A wait indication is displayed. 12. Tap Exit to close the update utility.

13. System configuration tutorial
13.3. System setup
This tutorial provides a stepbystep guide for configuration of a typical professional loudspeaker system and provides an overview of the basic features and operation of the frame. This tutorial describes how to configure 4channel frame for use with a generic 3way loudspeaker system (with separate HF, MF and LF drivers), plus a separate subwoofer. It assumes that the system is fed with analog outputs from a mixing console with one fullrange main output and a separate sub feed.
1. Connect the loudspeakers to the four power output channels: a. Channel 1 Low Frequency Driver b. Channel 2 Mid Range Driver c. Channel 3 High Frequency Driver d. Channel 4 Subwoofer
2. Connect the main output of the mixing console to analog input 1 of the frame and the sub feed to input 2. While configuring, it is a good practice to make sure the volume is turned down on the console.
3. Ensure the frame is powered on and is in its default state, and that the computer has established an active Ethernet connection.
4. On the Tablet PC, launch the Lake Controller software application. Select the appropriate network adapter if more than one is enabled, and tap NO to the dialog asking whether to load the previous configuration.
5. Tap MODULES button on the menu bar at the bottom of the screen to access the Module Menu and scroll bar.
6. On the Module scroll bar, the frame is represented with a frame containing four discs. These are labeled A, B, C and D, each representing one of the four Lake processing modules.
7. Tap the frame to select it, then tap again in the MAIN area of the screen to place all modules of the frame in the current system configuration. The Lake Controller uploads settings from the frame.
8. Tap the icon for Module A; its border will turn yellow to confirm selection and an LED on the front panel of the associated device will illuminate.
9. Tap the Module Store/Recall button on the Modules Menu; the menu will change to show additional options. 10. Doubletap the Default Modules folder, then doubletap the Contour Classic Crossovers folder. A set of
loudspeaker symbols will be displayed. 11. Tap CL3way, and then tap the RECALL button. This configures the DSP for the Module A as a 3way
crossover for the 3 way speaker. 12. Tap Yes when asked to confirm that all data will be overwritten. 13. An Output configuration dialog will pop up to allow for routing of module outputs to power channels. Tap the
orange number buttons in the matrix to unroute, freeing up a power channel. Tap a blue number button at the intersection of the appropriate module output and power channel, routing the module output to the power channel. Proceed until you have routing according to the picture below and tap the bottom right return button to exit the dialog.
36 D SERIES Lake Operation Manual rev 3.0.1

13. System configuration tutorial
14. The B module is already a CL1way as default and can be used to drive the sub. 15. Tap Store/Recall EXIT to return to the Modules Menu. 16. Ensuring Module A (or any other module that you want to control) is selected (yellow border), tap I/O Config.
17. The right side of the I/O CONFIG screen displays a block diagram for the Modules. Tapping the different blue blocks will access the configuration screens for Input mixer, Levels, Input EQ, Delay and Output EQ/Crossover respectively. The magnifying glass at the far right end accesses the output configuration. (NOTE: Tapping the blue return button (left arrow), or the EQ/Levels EXIT button in the menu bar returns to the I/O Config screen from the various configuration screens.)

47 D SERIES Lake Operation Manual rev 3.0.1

14. Appendix 14.3. Maintenance
During normal operation a D Series device provides troublefree service. If the front panel display requires cleaning, use a soft cloth only; do not use solvent cleaners. The dust filters on both sides of the front panel, behind the grilles, should occasionally be removed and cleaned to ensure maximum airflow through the device. Disconnect the unit from mains power prior to removing dust the filter, and ensure the dust filter is replaced prior to turning the unit back on. In extreme cases it may be necessary to clean the inside of the device. This procedure should only be carried out by qualified service personnel. Internal cleaning may be necessary if the device has had prolonged operation in an extreme environment such as one where cracked oil smoke machines are in use. If the device is used in extreme conditions, it is recommended to have it serviced every three years as a preventative measure.
