This symbol, wherever it appears, alerts you to the presence of uninsulated
dangerous voltage inside the enclosure - voltage that may be sufficient to constitute
a risk of shock.
This symbol wherever it appears, alerts you to important operating and
maintenance instructions in the accompanying literature. Read the manual.
DETAILED SAFETY INSTRUCTIONS:
Read these instructions
All the safety and operation instructions should be read before the apparatus is operated.
Keep these instructions
The safety and operating instructions should be retained for future reference.
Heed all warnings
All warnings on the apparatus and in the operating instructions should be adhered to
Follow all instructions:
All operation and user instructions should be followed
Water and moisture
Do not use this apparatus near water (e.g. near a bathtub, washbowl, kitchen sink, laundry tub, in a wet
basement, or near a swimming pool etc.) except expressly allowed
Cleaning
Clean only with a dry cloth. Do not use solvents, alcohol, benzene or volatile substances for cleaning
the exterior parts.
Ventilation
Do not block any of the ventilation openings. Install in accordance with the manufacturers instructions.
The apparatus should be situated so that its location or position does not interfere with its proper
ventilation.
Heat
Do not install the apparatus near any heat sources such as radiators, heat registers, stoves, or other
apparatus (including amplifiers) that produce heat.
Grounding or Polarization
Do not defeat the safety purpose of the polarized or grounding/type plug. To prevent the risk of
electrical shock, the metallic parts of the speaker must be earthed. A polarized plug has two blades
with one wider than the other. A grounding type plug has two blades and a third grounding prong. The
wide blade or the third prong are provided for your safety. When the provided plug does not fit into your
outlet, consult an electrician for replacement of the obsolete outlet.
Speaker shall be connected to a MAINS socket outlet with a protective earthing connection.
Power Source
The apparatus should be connected to a power supply only of the type described in the operating
instructions or as marked on the apparatus. In order not to jeopardize the safety of the speaker, it must
only be connected to the mains using the power cable provided.
DPDT Mains Switch is used as the disconnect device located at the rear.
Power Cord Protection
Protect the power cord from being walked on or pinched particularly al plugs, convenience receptacles,
and the point where they exit from the apparatus.
Accessories
Only use attachments/accessories specified by the manufacturer.

PROTECTION SYSTEM
Carts and stands
Use only with a 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.
Non-use Periods:
Unplug this apparatus during lightning storms or when unused for long periods of time.
Object and Liquid Entry
Care should be taken so that objects do not fall and liquids are not spilled into the enclosure through
openings.
Damage Requiring Service
Refer all servicing to qualified service personnel. Servicing is required when:
- the apparatus has been damaged in any way;
- the power-supply cord or the plug has been damaged;
- the liquid had been spilled or objects have fallen into the apparatus;
- the apparatus has been exposed to rain or moisture
- the apparatus does not operate normally or exhibits a marked change in performance;
- the apparatus had been dropped.
Servicing:
The user should not attempt to service the apparatus beyond that is described in the Operating
Instructions. All other servicing should be referred to qualified service personnel.
This manual is to be considered an integral part of the product, and must always accompany the
speaker when it changes ownership as a reference for correct installation and operation as well as for
the safety regulations.
dB Technologies will not assume any responsibility for incorrect installation of the speaker.
- Do not force the amplifier incorporated in the speaker to work in overload for extended periods
of time.
- Never force the control elements (switches, controls, etc.).
CAUTION
- Make sure that the speaker is positioned in a stable and secure way in order to avoid any
dangerous conditions for persons or objects.
CAUTION
- For connecting the speaker, use only qualified and experienced personnel having sufficient
technical knowledge or specific instructions for making the connections correctly and thus
preventing electrical dangers.
- To prevent the risk of electrical shock, the speaker must only be supplied from the mains after all
connections have been completed.
- Before powering up the speaker, it is advisable to re-check all the connections, making sure in
particular that there are no short circuits.
- The entire sound system must be designed and installed in compliance with the current
standards and regulations regarding electrical systems.
CAUTION
- To prevent inductive phenomena from giving rise to hum or disturbance which would jeopardize
efficient speaker operation, the cables that transmit microphone signals or line level signals
(e.g. 0 dB/V) must be screened and should not be run in the vicinity of:
1) Equipment that produces strong magnetic fields (e.g. large power supply transformers)
2) Electrical energy conductors
3) Lines that supply speakers.
The speaker is equipped of a exclusive system, which protects the loudspeakers against overheating,
ensuring the maximum reliability in all professional applications. In addition, a sophisticated system
incorporated in the amplifier handles the limiter circuits and the protection against overheating and
short circuits.
