3.4. User responsibility
3.4.1. Mains connection grounding
Your amplifier must be connected to a grounded socket outlet.

3.4.2. 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.

3.4.3. Radio interference
A sample of this product has been tested and complies with
the limits for the European Electro Magnetic Compatibility
(EMC) directive. This equipment has also been tested and
found to comply with the limits for a Class A digital device,
pursuant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful
interference from electrical equipment. This product uses
radio frequency energy and if not used or installed in
accordance with these operating instructions, may cause
interference to other equipment, such as radio receivers.
This Class A digital apparatus complies with Canadian ICES-003.
Cet appareil numérique de la classe A est conforme à la norme NMB-003
du Canada.

However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which
can be determined by turning the equipment on and off, the
user is encouraged to try to correct the interference by one or
more of the following measures:
• Reorient or relocate the antenna.
• Increase the separation between the equipment and
receiver.
• Connect the equipment to an outlet on a circuit different
from that to which the receiver is connected.
• Check if the affected unit complies with the EMC limits for
immunity, (CE-labeled). If not, address the problem with
the manufacturer or supplier. All electrical products sold
in the EC must be approved for immunity against
electromagnetic fields, high voltage flashes, and radio
interference.
• Consult the dealer or an experienced radio/TV technician
for help.

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
the warranty.

3.3. Attention
Pour réduire le risque d’incendie et de choc électrique, ne
retirez pas les vis. Aucune pièce interne n’est réparable par
l’utilisateur. Confiez toute réparation à des techniciens de
maintenance qualifiés.

3.4. Responsabilité de l’utilisateur
3.4.1. Mise à la terre de la prise secteur
Votre amplificateur doit être connecté à une prise de terre.

3.4.2. Danger aux sorties pour enceintes des
		amplificateurs
Les amplificateurs sont capables de produire des tensions
de sortie dangereuses. Pour éviter tout choc électrique, ne
touchez aucun fil d’enceinte nu quand l’amplificateur est en
service. Le câble externe connecté aux borniers d’enceintes
doit être préparé par une personne qualifiée, sinon des
cordons tout prêts de capacité appropriée doivent être
utilisés.
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
conformément à ces instructions d’utilisation, peut causer
des interférences avec d’autres appareils, tels que les
radiorécepteurs.

This Class A digital apparatus complies with Canadian ICES-003.
Cet appareil numérique de la classe A est conforme à la norme NMB-003
du Canada.

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 :
• 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

3.4.1. Toma de tierra de la conexión eléctrica
Debe conectar este amplificador a una salida de corriente dotada
de toma de tierra de seguridad.

3.4.2. Riesgos de las salidas de altavoces de los
amplificadores
Los amplificadores son capaces de producir voltajes de salida
potencialmente peligrosos. Para evitar una descarga eléctrica, no
toque ningún cable de altavoz desnudo mientras el amplificador
esté en marcha. La conexión de cables a las terminales
de altavoces debe ser realizada por un profesional, o debe
asegurarse en todo caso de usar cables específicos para ello y
de unas especificaciones adecuadas.
Dado que los canales de salida de potencia de los amplificadores
producen un alto voltaje, no conecte ni desconecte cables de
altavoz con la unidad encendida.

3.4.3. Interferencias de radio
Se ha verificado que este aparato cumple con los límites
establecidos por la directiva europea de compatibilidad
electromagnética (EMC). También se ha verificado que este aparato
cumple con los límites establecidos para dispositivos digitales de
clase A, de acuerdo a lo expuesto en el apartado 15 de las normas
FCC. Estos límites han sido diseñados para ofrecer una protección
razonable contra las interferencias molestas procedentes de
aparatos eléctricos. Este aparato usa energía de radiofrecuencia
y, si no es instalado y usado de acuerdo a lo indicado en estas

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 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
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
PLM+ Series has a universal power supply and its mains nominal and operating voltages are specified in the
Technical Specifications (see section 15). 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
PLM+ Series Devices on the same AC mains circuit to be turned on simultaneously.

9. Operating voltage

9.1. Low voltage country considerations
Although the 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.

11. Product overview

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 full PLM+ Series Operation Manual. Additional
information is also available in the Lake Network Configuration Guide.

Note: Additional processor configuration is required for a dual redundant network setup. See the Lake
Controller Operation Manual for further details.

Note: Do not create a closed loop when configuring multiple devices in an Ethernet network; this will
cause a network malfunction.

6 Secondary Network Connector – The secondary network connector can be used to daisy-chain multiple
PLM+ Series 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.

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.

13.4. 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.

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
