3.4.4. 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.
3.4.5. Maintenance
For safe and reliable operation, the dust fi lters on both sides
of the front panel, behind the grilles, 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 fi lters are not clean and the unit
malfunctions, any resulting problems will not be covered by

Comme les canaux de sortie de puissance des amplificateurs
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 fixées par la Directive européenne sur la
compatibilité électromagnétique (CEM). Cet équipement a
aussi été testé et trouvé conforme aux limites fixées 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

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 :
• R
éorienter 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.
• Vérifier 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 certifiée 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 amplificateur 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. Vérifiez toujours les puissances admissibles par
l’enceinte, en continu et en crête. Bien que des atténuateurs
d’amplificateurs 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 fiable, les filtres à poussière,
des deux côtés de la face avant derrière les grilles, doivent
être retirés et nettoyés régulièrement afin d’assurer une
circulation maximale de l’air au travers de l’appareil.
Ne pas entretenir les filtres à poussière entraîne des risques
pour la sécurité ; par exemple, une surchauffe interne peut
amener la poussière à s’enflammer, 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 filtres 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.

3.4. Verantwortung des Anwenders
3.4.1. Erdung Netzanschluss
Ihr Verstärker muss an eine geerdete Steckdose angeschlossen
werden.
3.4.2. Lautsprecherausgang an Verstärkern – Gefahr
Verstärker können gefährliche Ausgangsspannungen erzeugen.
Um einen elektrischen Schlag zu vermeiden, dürfen Sie freiliegende
Lautsprecherkabel nicht berühren, während der Verstärker in Betrieb
ist. Der Anschluss externer Kabel an die Lautsprecherklemmen muss
von einer hierfür qualifizierten Person vorgenommen werden, oder es
müssen vorgefertigte, hierfür geeignete Kabel verwendet werden.
Da an den Leistungsausgängen von Verstärkern Hochspannung
anliegt, dürfen Lautsprecherkabel nicht angeschlossen oder
abgezogen werden, so lange der Verstärker mit Netzspannung
versorgt wird.
3.4.3. Rundfunkstörungen
B nach Abschnitt 15. Diese Einschränkungen sollen angemessenen
Schutz vor schädlichen Störungen durch elektrische Geräte
gewährleisten. Dieses Gerät verwendet Hochfrequenzenergie. Wenn
es nicht entsprechend der Anleitung installiert und verwendet wird,
erzeugt es möglicherweise beeinträchtigende Störungen bei anderen
Geräten, beispielsweise Rundfunkempfängern.
Dieses digitale Gerät der Klasse A entspricht den
kanadischen Bestimmungen für Interferenz verursachende
Geräte ICES-003.
Cet appareil numérique de la classe A est conforme à la
norme NMB-003 du Canada.
Es kann jedoch nicht garantiert werden, dass es bei einer bestimmten
Aufstellung nicht zu Interferenzen kommt. Wenn dieses Gerät
Störungen bei Radio- und Fernsehempfangsgeräten auslöst – was
durch Aus- und Anschalten des Gerätes überprüft werden kann –
sollten Sie die folgenden Maßnahmen ergreifen:
• Richten Sie die Antenne neu aus oder stellen Sie die Antenne an
einer anderen Stelle auf.
• Vergrößern Sie den Abstand zwischen dem Gerät und dem
Empfänger.
• Schließen Sie das Gerät an eine Steckdose an, die zu einem
anderen Stromkreis als der Empfänger gehört.
• Prüfen Sie, ob das betroffene Gerät den EMV-Grenzwerten für
Störfestigkeit (CE-Kennzeichnung) entspricht. Wenn dies nicht
der Fall ist, müssen Sie das Problem mit dem Hersteller oder
Lieferanten dieses Produkts klären. Für alle elektrischen Produkte,
die innerhalb der EU verkauft werden, muss eine Zulassung
vorliegen, welche die Störfestigkeit gegen elektromagnetische
Felder, Spannungsüberschläge oder Funkstörungen bestätigt.
• Bitten Sie Ihren Händler oder einen erfahrenen Radio-/
Fernsehtechniker um Hilfe.
3.4.4. Beschädigung der Lautsprecher
Dieser Verstärker verfügt über eine sehr hohe Leistung und
kann sowohl angeschlossene Lautsprecher als auch Menschen
gefährden. Viele Lautsprecher können durch zu hohe Leistung
leicht beschädigt oder zerstört werden. Achten Sie stets auf die
Dauer- und Spitzenleistung der verwendeten Lautsprecher. Obwohl
Dämpfungsglieder im Verstärker zum Absenken der Ausgangsleistung
verwendet werden können, wird möglicherweise bei einer Anhebung
des Eingangssignalpegels die volle Ausgangsleistung abgegeben,
was zu Schäden an den angeschlossenen Lautsprechern führen
kann.
3.4.5. Wartung
Um einen sicheren und zuverlässigen Betrieb zu gewährleisten,
sollten die Staubfilter auf beiden Seiten der Frontplatte, hinter den
Gittern, in regelmäßigen Abständen entfernt und gereinigt werden, um
einen maximalen Luftstrom durch das Gerät zu gewährleisten.
Wenn die Staubfilter nicht instandgehalten werden, kommt es zu
Sicherheitsrisiken. So kann es beispielsweise zu hohen Temperaturen
im Geräteinneren kommen, die den Staub entzünden und ein Feuer
auslösen können. Es besteht auch die Gefahr von Fehlfunktionen,
da für den Betrieb des Gerätes ein konstanter Luftstrom von der
Vorderseite zur Rückseite erforderlich ist. Wenn die Staubfilter nicht
sauber gehalten werden und es zu einer Funktionsstörung des
Gerätes kommt, so werden die resultierenden Probleme nicht durch

radio/TV para que le ayuden.
3.4.4. Daños en los altavoces
Los amplificadores son muy potentes y pueden llegar a
resultar potencialmente peligrosos tanto para los altavoces
como para las personas. Muchos altavoces pueden resultar
dañados fácilmente o incluso destruidos por una sobrecarga.
Verifique siempre cuáles son las capacidades de potencia
continua y en picos del altavoz. Aunque puede usar los
atenuadores del amplificado para reducir la ganancia global,
un aumento de la señal de entrada puede dar lugar a una
señal a máxima potencia de salida, capaz de dañar los
altavoces conectados.
3.4.5. Mantenimiento
Para garantizar un funcionamiento seguro y fiable, debe retirar y
limpiar de forma regular los filtros de polvo que se encuentran a
ambos lados del panel frontal, detrás de las rejillas, asegurando
así un correcto flujo de aire.
El no realizar este mantenimiento preventivo de los filtros puede
dar lugar a riesgos de seguridad; por ejemplo, la elevada
temperatura interna puede hacer que el polvo llegue a arder

7. Installation
7.2. Mounting
PLM+ 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.
7.2.1. Rear Mounting
Two rear support brackets, along with associated mounting hardware, are included with the PLM+ 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 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.

8. Cooling and fan operation
8. Cooling and fan operation
PLM+ devices use a forced-air 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 PLM+ 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 K&F PLM+ 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 PLM+ devices in a rack with other fan-cooled equipment, confirm that all 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
K&F PLM+ Series devices.
The PLM+ 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
K&F PLM+ Series has a universal power supply and its mains nominal and operating voltages are specified in the
Technical Specifications (see section 15). K&F PLM+ 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 locally-sourced 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: In-rush current is controlled and limited during the soft-start sequence. This enables multiple K&F
PLM+ Series Devices on the same AC mains circuit to be turned on simultaneously.
K&F PLM+ SERIES Quick Start Guide rev 2.0.0

9. Operating voltage
9.1. Low voltage country considerations
Although the K&F PLM+ Series has a wide range of operating mains voltage, some considerations can be
applicable for low voltage regions. PLM+ 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.
Note: Following connections applicable only for resulting voltage inside the amplifiers nominal
voltage range.
Connecting the amplifier in three phase delta configuration
In three-phase 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.

13. Quick Start 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 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 traffic needs to be filtered from reaching the
wireless links.
13.1.2. Network configuration
Frames are configured 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 configured 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 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 range.

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
and Dante discovery services. Download the Lake Controller installation from www.labgruppen.com.
2. Execute the installer and follow the on-screen 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 on-screen 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.
(Four corner LEDs will blink yellow in circular pattern.)
10.Tap OK and cycle the mains power on all updated frames by completely removing the power plug and
reinserting it. (Note: 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. This process can take ten minutes or more. When concluded, if the top left LED blinks yellow,
another power cycle is required.
12.Tap Exit to close the update utility.

13. Quick Start Tutorial
13.3. System setup
This tutorial provides a step-by-step guide for configuration of a typical professional loudspeaker system and
provides an overview of the basic features and operation of the frame. It describes how to configure 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.

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
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.
Ensure the frame is powered on and is in its default state, and that the computer has established an active
Ethernet connection.
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.
Tap MODULES button on the menu bar at the bottom of the screen to access the Module Menu and scroll
bar.
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.
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.

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.
Tap the Module Store/Recall button on the Modules Menu; the menu will change to show additional options.
Double-tap the Default Modules folder, then double-tap the Contour Classic Crossovers folder. A set of
loudspeaker symbols will be displayed.
Tap CL3way, and then tap the RECALL button. This configures the DSP for the Module A as a 3-way
crossover for the 3 way speaker.
Tap Yes when asked to confirm that all data will be overwritten.
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 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 across. Tap the bottom right return button
to exit the dialog.

22. Use the control options mentioned in 17 to tune your loudspeakers. For larger systems, modules can be
placed in groups (Groups menu from the MAIN page) for control of multiple units.
13.4. Rational Power Management™
Rational Power Management™ (RPM) is a unique Lab.gruppen feature that allows for flexible allocation of power
across channels of a PLM+. Power that is not used by one output channel is free for use by another output
channel with greater demands. RPM allocates power up to the total limits of the specific amplifier model. RPM
exists in two modes. See the image below.

13. Quick Start Tutorial
Auto RPM:
The frame will automatically allocate power per output channel according to the ISVPL settings in the Lake module.
If the ISVPL settings taken together allow total output higher than the capabilities of the amplifier, RPM will reduce
the ISVPL limiter thresholds evenly based on a proportional reduction in dB. When RPM is active, an RPM icon will
be displayed next to the “Actual ISVPL” values in the Events & Control section.
Custom RPM:
The Café software allows users to create an advanced custom power allocation scheme. Switching to Custom
mode disables the Automatic mode. When RPM is active an RPM icon will be displayed next to the “Actual ISVPL”
values in the Events & Control section. Please find more information about this in the CAFÉ Operation Manual
