IMPORTANT SAFETY INSTRUCTIONS
Explanation of Graphical Symbols
The lightning flash with arrowhead symbol within an
equilateral triangle is intended to alert the user to
the presence of uninsulated “dangerous voltage”
within the product’s enclosure that may be of
sufficient magnitude to constitute a risk of electric
shock to persons.
The exclamation point within an equilateral triangle
is intended to alert the user to the presence of
important operating and maintenance instructions in
the literature accompanying the product.
1. Read these instructions.
2. Keep these instructions.
3. Heed all warnings.
4. Follow all instructions.
5. Do not use this apparatus near water.
6. Clean only with dry cloth.
7. Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions.
8. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus
(including amplifiers) that produce heat.
9. Do not defeat the safety purpose of the grounding-type plug. A grounding-type plug has two blades
and a third grounding prong. The third prong is provided for your safety. If the provided plug does not
fit into your outlet, consult an electrician for replacement of the obsolete outlet.
10. Protect the power cord from being walked on or pinched particularly at plugs, convenience
receptacles, and the point where they exit from the apparatus.
11. Only use attachments/accessories specified by the manufacturer.
12. Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer, or
sold with the apparatus. When a cart is used, use caution when moving the cart/apparatus
combination to avoid injury from tip-over.
13. Unplug this apparatus during lightning storms or when unused for long periods of time.
14. Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been
damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects
have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate
normally, or has been dropped.
15. WARNING: To reduce the risk of fire or electric shock, this apparatus should not be exposed to rain
or moisture and objects filled with liquids, such as vases, should not be placed on this apparatus.
16. To completely disconnect this equipment from the mains, disconnect the power supply cord plug from
the receptacle.
17. The main plug of the power supply cord shall remain readily operable.

ADDITIONAL IMPORTANT SAFETY INSTRUCTIONS
1. Read this document.
2. Read all SAFETY INSTRUCTIONS carefully as well as DANGER and OBLIGATION warnings.
3. Never incorporate equipment or accessories not approved by L-ACOUSTICS®.
4. Read the USER MANUAL before installing and operating the apparatus.
Use the system components described in the user manual and follow the associated instructions.
To ensure sufficient ventilation, install the apparatus in an open area so that the front and rear panels are located
at a minimum distance of 30 cm from any external object or structure.
5. Read the MAINTENANCE MANUAL –LEVEL 1 before performing any maintenance operation on the
apparatus or in case of malfunction.
This manual only contains the maintenance operations authorized for the End User. Contact L-ACOUSTICS®for
advanced maintenance.
6. Inspect the apparatus before use.
If any sign of defect or damage is detected, immediately withdraw the apparatus from use for maintenance.
7. Only use the apparatus in a conformed electro-magnetic environment.
Conformed environments are specified in EN55103-2 standard as E1 (residential), E2 (commercial and light
industrial), E3 (urban outdoors), and E4 (controlled EMC environment, ex. TV studio).
8. Avoid radio interference.
This apparatus has been tested and complies with the limits indicated in the EMC (Electro Magnetic Compatibility)
directive. These limits are designed to provide reasonable protection against harmful interference from electrical
equipment, but it cannot be guaranteed that interference will never occur.
9. Verify the electrical conformity and compatibility of the mains supply.
Only connect the apparatus to an AC power outlet rated 100-240 V, 50-60 Hz, with the following current values:
20 A for 100-120 V, 10 A for 200-240 V.
WARNING: An apparatus with CLASS I construction shall be connected to a mains socket outlet with a protective
connection to earth.
10. Verify the electrical conformity and compatibility of the three-phase circuit.
Verify that each phase works, in particular the neutral one.
Balance the loads between the three phases.
Never try to reproduce a 230 V circuit connecting an apparatus to two live wires of a 120 V three-phase circuit.
Never try to reproduce a 200 V circuit connecting an apparatus to two live wires of a 100 V three-phase circuit.
11. Always interconnect a Class C thermal circuit breaker between the apparatus and the mains supply.
The circuit breaker current rating depends on the mains voltage rating as follows:
20 A for 100-120 V, 10 A for 200-240 V.
12. Be aware of over power risks.
The apparatus is very powerful and can be potentially dangerous to both loudspeakers and humans alike.
Even reducing the gain it is still possible to reach very high output power if the input signal level is high enough.
13. Do not use the apparatus outside its operating temperature range.
The apparatus operates at a room temperature between 0 °C and +50 °C.
Do not expose the apparatus to direct sun.
14. WARNING: TERMINALS marked with the lightning flash symbol are HAZARDOUS LIVE.
The external wiring connected to these TERMINALS requires installation by an INSTRUCTED PERSON
or the use of ready-made leads or cords.
Never attempt to touch any exposed speaker wiring while the apparatus is operating: first disconnect the
connector from the apparatus.
Mute all output channels before connecting a speaker to the apparatus.
Do not connect a speaker output in parallel or series with any output of another amplifier.
Do not connect the speaker outputs to any other voltage source, such as a battery, power mains, or
power supply, regardless of whether the apparatus is turned on or off.

8. Evite interferencias de radio.
Este aparato ha sido probado y cumple con los límites indicados en la directiva de compatibilidad electro
magnética EMC (Electro Magnetic Compatibility). Estos límites se han diseñado para proporcionar una protección
razonable frente interferencias perjudiciales generadas por equipos eléctricos, pero esto no garantiza que no se
puedan producir alguna vez.
9. Verifique la conformidad y la compatibilidad de la corriente.
Conecte el aparato solamente a un enchufe o base de corriente alterna en un rango de 100-240 V, 50-60 Hz, con
los siguientes valores de intensidad de la corriente: 20 A para 100-120 V, 10 A para 200-240 V.
ATENCION: Un aparato de construcción CLASS I debe ser conectado a una base de corriente con conexión a
tierra.
10. Verifique la conformidad eléctrica y la compatibilidad del circuito trifásico.
Verifique que cada fase trabaje normalmente, en particular el neutro.
Reparta la carga entre las tres fases.
No intente reproducir un circuito de 230 V conectando un aparato a dos fases de un circuito trifásico de 120 V.
No intente reproducir un circuito de 200 V conectando un aparato a dos fases de un circuito trifásico de 100 V.
11. Intercale siempre un circuito de protección magneto térmico de Class C entre el aparato y la toma de
corriente.
El magneto térmico debe tener estos valores de amperaje:
20 A para 100-120 V, 10 A para 200-240 V.
