ADDITIONAL IMPORTANT SAFETY INSTRUCTIONS
1. Read this manual.
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 all the related PRODUCT INFORMATION documents before exploiting a loudspeaker system.
The product information document is included in the shipping carton of the related system component.
5. Strictly follow the installation instructions given in this manual.
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.
6. 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
advanced maintenance.
7. Inspect the apparatus before use.
If any sign of defect or damage is detected, immediately withdraw the apparatus from use for maintenance.
8. 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).
9. 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.
10. 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.
11. 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.
12. 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.
13. 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.
14. 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.
15. 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.
