3.4.1. Mise à la terre de la prise secteur

Votre ampliﬁ cateur doit être connecté à une prise de terre.

3.4.2. Danger aux sorties pour enceintes des ampliﬁ cateurs

Les ampliﬁ cateurs sont capables de produire des tensions de sortie dangereuses. Pour éviter tout choc électrique, ne touchez aucun ﬁ l d’enceinte nu quand l’ampliﬁ cateur est en service. Le câble externe connecté aux borniers d’enceintes doit être préparé par une personne qualiﬁ ée, sinon des cordons tout prêts de capacité appropriée doivent être utilisés.

Comme les canaux de sortie de puissance des ampliﬁ cateurs produisent une tension élevée, les câbles d’enceintes ne doivent pas être branchés ou débranchés quand l’appareil est sous tension.

3.4.3. Interférences radioélectriques

Un échantillon de ce produit a été testé et déclaré conforme aux limites ﬁ xées par la Directive européenne sur la compatibilité électromagnétique (CEM). Cet équipement a aussi été testé et trouvé conforme aux limites ﬁ xées pour un appareil numérique de Classe A par la partie 15 de la réglementation FCC. Ces limites sont conçues pour assurer une protection raisonnable contre les interférences nuisibles causées par des appareils électriques. Ce produit utilise des ondes radioélectriques et, s’il n’est pas installé et utilisé conformément à ces instructions d’utilisation, peut causer des interférences avec d’autres appareils, tels que les radiorécepteurs.

L’absence d’interférences n’est toutefois pas garantie pour une installation donnée. Si cet équipement provoque des interférences nuisibles à la réception de la radio ou de la télévision, ce qui peut être déterminé en allumant et en éteignant l’équipement, l’utilisateur est encouragé à essayer de corriger les interférences en prenant une ou plusieurs des mesures suivantes :

• Réorienter ou déplacer l’antenne.

• Augmenter l’espace séparant l’équipement du récepteur.

• Brancher l’équipement à une prise d’un circuit différent de celui auquel est branché le récepteur.

• Vériﬁ er si l’unité concernée est conforme aux limites de CEM pour l’immunité (étiquetage CE). Sinon, résolvez le problème avec le fabricant ou le fournisseur. Tous les produits électriques vendus en UE doivent avoir une immunité certiﬁ ée contre les champs électromagnétiques, les surtensions, et les interférences radioélectriques.

• Consulter le revendeur ou un technicien radio/TV expérimenté pour obtenir de l’aide.

3.4.4. Dommages causés aux enceintes

Un ampliﬁ cateur est très puissant et peut être potentiellement dangereux à la fois pour les enceintes et pour les êtres humains. De nombreuses enceintes peuvent être facilement endommagées ou détruites si on les soumet à une puissance excessive. Vériﬁ ez toujours les puissances admissibles par l’enceinte, en continu et en crête. Bien que des atténuateurs d’ampliﬁ cateurs puissent être utilisés pour réduire le gain général, une augmentation du signal d’entrée peut conduire à une sortie à pleine puissance risquant d’endommager les enceintes connectées.

3.4.5. Entretien

Pour un fonctionnement sûr et ﬁ able, les ﬁ ltres à poussière, des deux côtés de la face avant derrière les grilles, doivent être retirés et nettoyés régulièrement aﬁ n d’assurer une circulation maximale de l’air au travers de l’appareil.

Ne pas entretenir les ﬁ ltres à poussière entraîne des risques pour la sécurité ; par exemple, une surchauffe interne peut amener la poussière à s’enﬂ ammer, déclenchant un incendie. Il existe également un risque de mauvais fonctionnement de l’unité car celle-ci nécessite un débit d’air constant de l’avant vers l’arrière. Si les ﬁ ltres à poussière ne sont pas propres et si l’appareil ne fonctionne pas correctement, les problèmes qui en résultent ne sont pas couverts par la garantie.

Every Lab.gruppen 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.

7.1.1. Included in the box

In addition to the D Series device, the shipping carton includes the following items:

• D Series Lake Quick Start Guide (this document)

• AC mains lead (power cable) with Neutrik powerCON connector (D 200, D 120 and D 80) or locking IEC connector (D 40, D 20 and D 10) and AC socket plug according to ordering selection

• Rear brackets for additional rear rack support (pair) along with associated mounting hardware

• Connector kit including all needed connectors

• Front grille and dust ﬁ lter assembly

NOTE: Depending on the model, the connector kit might include more connectors than applicable for the product you have. Select those connectors required for your unit and application.

Please keep the original carton and associated packaging to facilitate shipping of the device should the need arise.

7.2. Mounting

D Series is made for mounting in 19 inch racks. Four screw holes are available for attachment of the ampliﬁ er 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. Sufﬁ cient 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.

7.2.1. 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 ﬁ tting options for ﬁ xed and removable installation. The support brackets are reversible and may be ﬁ tted 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.

7.2.2. Mounting front grille

The front grille is shipped on top of the ampliﬁ er inside the box to protect it during shipping. The front grille adheres to the ampliﬁ er with magnets. Hold the front grille with your ﬁ ngers in each of the side cutouts and slide it gently into place straight from the front.

NOTE: Always ensure the dust ﬁ lters behind the detachable front panel are clean to allow maximum possible airﬂ ow. The exterior front panel is held in place by powerful magnets but is easy to detach by using your ﬁ ngers in the openings at the each side. To clean the foam ﬁ lter, detach it from the exterior front and gently use a vacuum cleaner or gently shake it. Remount with the opposite procedure. Never operate the ampliﬁ er without the dust ﬁ lter installed.

8. Cooling and fan operation

10. Grounding

D SERIES Lake Quick Start Guide rev 3.0.3

8. Cooling and fan operation

D Series devices use a forced-air cooling system with airﬂ ow from front to rear, allowing high continuous power levels without thermal problems. To facilitate maximum air ﬂ ow, 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 airﬂ ow. Make sure an adequate air supply is provided in front of the D Series device, and that the rear of the device has sufﬁ cient 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 signiﬁ cant 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 forced-air cooling.

If installing one or more D Series devices in a rack with other fan-cooled equipment, conﬁ rm that all other equipment also uses front-to-rear airﬂ ow for cooling. If this precaution is not observed, there is a risk of overheating, as units with the reverse airﬂ ow 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.

9. Operating voltage

D Series has a universal power supply and its mains nominal and operating voltages are speciﬁ ed in the Technical Speciﬁ cations (Section 15). D Series can be ordered with a variety of mains plugs. If the mains plug (AC plug) ﬁ tted to the mains cable (AC cord) is not appropriate for your country it can be removed and a locally-sourced one ﬁ tted instead. If you are not 100% conﬁ dent of your competence to replace the mains plug (AC plug), the task should be carried out by qualiﬁ ed personnel.

NOTE: In-rush current is controlled and limited during the soft-start sequence. This enables multiple D Series Devices on the same AC mains circuit to be turned on simultaneously.

9.1. 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 speciﬁ ed nominal voltage range but has slightly better efﬁ ciency at higher voltages. For regions with nominal voltage below 140 V, one could consider connecting the ampliﬁ er in a three phase delta or two phase split-phase conﬁ guration, especially applicable for the bigger models, (D 200, D 120 and D 80).

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

Connecting the ampliﬁ er in three phase delta conﬁ guration

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

12. Signal ﬂ ow and processing

12.1. Signal ﬂ ow

The ﬁ gure below depicts the audio signal ﬂ ow for a D Series Lake device. It is worth noting that this sophisticated device provides seven points in the signal chain where the signal level can be adjusted, muted or disconnected.

Figure 12.1: D Series Lake Signal Flow Diagram

The input section (inputs, input router and input mixer) allows for mixing capabilities as well as redundant and

prioritized inputs with automatic switch-over in case of signal failure

Up to four Lake Processing modules provide user EQ and loudspeaker processing, including LimiterMax limiting

The Output router allows free routing between module outputs and power output channels

Each power output channel provides individual channel processing, including ISVPL limiter, RPM and

load monitoring

Power ampliﬁ er

12.2. Level Adjustments & Mute Points

The following points in the signal ﬂ ow can adjust level or mute the signal:

1 Input Router Stage Input selection and MUTE 2 Input Mixer Stage Router on /off connection to mixer and gain settings 3 Module Input Stage Mute and gain settings 4 Module Output Stage Mute and gain settings 5 Output Router Stage Output on /off routing connections 6 Attenuation Stage Power output channel mute and attenuation settings 7 Amp Gain Stage Ampliﬁ er gain control

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

13. System conﬁ gration 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 conﬁ gured in dual redundancy mode to support a second redundant network. The alternate conﬁ guration for the two ports is a switch mode which allows daisy–chaining 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.

NOTE: If using Dante audio in the network, the audio trafﬁ c needs to be ﬁ ltered from reaching the wireless links.

13.1.2. Network conﬁ guration

Frames are conﬁ gured by default to obtain IP addresses automatically. The frame will assign itself an IP address in the link local range (169.254.1.0 through 169.254.254.255). If a computer is conﬁ gured the same way (which should be default on modern operating systems), it will reside in the same subnet as the devices and communication can be established. Alternate conﬁ gurations would be DHCP for a managed network or ﬁ xed IP. To connect to the secondary network in dual redundancy mode the computer shall be conﬁ gured with an IP address in the 172.31.0.0 – 172.31.255.255.

Ampliﬁ ers with ﬁ rmware associated with Lake Controller 6.5.0 or later will automatically power cycle the mains power, whereas ampliﬁ ers with older ﬁ rmware 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 ﬁ rmware 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.

13.3. System setup

This tutorial provides a step–by–step guide for conﬁ guration of a typical professional loudspeaker system and provides an overview of the basic features and operation of the frame. This tutorial describes how to conﬁ gure 4–channel frame for use with a generic 3–way 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 conﬁ guring, 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 conﬁ guration.

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 conﬁ guration. The Lake Controller uploads settings from the frame.

8. Tap the icon for Module A; its border will turn yellow to conﬁ rm 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. Double–tap the Default Modules folder, then double–tap the Contour Classic Crossovers folder. A set of loudspeaker symbols will be displayed.

11. Tap CL3way, and then tap the RECALL button. This conﬁ gures the DSP for the Module A as a 3–way crossover for the 3 way speaker.

12. Tap Yes when asked to conﬁ rm that all data will be overwritten.

13. An Output conﬁ guration dialog will pop up to allow for routing of module outputs to power channels. Tap the orange number buttons in the matrix to un–route, 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.

13. System conﬁ gration tutorial

D SERIES Lake Quick Start Guide rev 3.0.3

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 Conﬁ g.

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 conﬁ guration screens for Input mixer, Levels, Input EQ, Delay and Output EQ/Crossover respectively. The magnifying glass at the far right end accesses the output conﬁ guration. (NOTE: Tapping the blue return button (left arrow), or the EQ/Levels EXIT button in the menu bar returns to the I/O Conﬁ g screen from the various conﬁ guration screens.)

Input Mixer Conﬁ guration – Drag sliders and tap ON/OFF buttons to control input mixer settings.

Levels Control - Drag sliders and tap mute buttons for module

input and output channels.

Delay Control - Drag sliders to control input and output delay Crossover control – Select ﬁ lters and drag on the bottom

frequency bar to adjust crossover frequency. Crossover types may be changed by selecting the Crossover Functions button.

Parametric EQ control – Select ﬁ lter on the top squares and adjust ﬁ lter properties by dragging the controls. Sliders at the bottom control center frequency and Q (bandwidth). Gain is controlled in the main window area. Additional ﬁ lters can be added by tapping the top ﬁ lter objects and placing new ﬁ lters on the main area.

18. Tap the Input Gain button in the block diagram and unmute the Module Input Mute. Tap EQ/Levels Exit to return to IO Conﬁ g.

19. The left side of the IO conﬁ g screen holds frame conﬁ guration and summary for Clock conﬁ guration, Input conﬁ guration, Dante conﬁ guration, Breaker Emulation Limiter conﬁ guration and Analog Iso–Float & AES Termination conﬁ guration. All these conﬁ gurations should be correct by default for this example.

20. From I/O conﬁ g, tap Ampliﬁ er Events & Control and navigate to the Status tab. Unmute the power channels and slowly increase the volume on the appropriate feed from the mixing console. Audio should now be active at the outputs and heard through the loudspeakers. Close the Ampliﬁ er Events & Control dialog with the return button and

return to the main area by tapping the I/O Conﬁ g EXIT button.

Ampliﬁ er Events & Control, Status tab – Drag sliders to adjust power channel attenuation and tap mute buttons to control power channel mute. Metering and Status monitoring is available for each power channel.
