SAFETY INSTRUCTIONS

CAUTION: TO REDUCE THE RISK OF

ELECTRICAL SHOCK, DO NOT
REMOVE THE COVER (OR BACK). NO
USER SERVICEABLE PARTS INSIDE;
REFER SERVICING TO QUALIFIED
PERSONNEL.

WARNING: TO REDUCE THE RISK OF FIRE OR

ELECTRICAL SHOCK. DO NOT
EXPOSE THIS APPARATUS TO RAIN
OR MOISTURE.

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.)

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.

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.

IMPORTANT NOTES

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.

OPERATING PRECAUTIONS

- 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.

CONNECTION

- 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.

PROTECTION SYSTEM

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.

Unplug this apparatus during lightning storms or when unused for long periods of time.

Care should be taken so that objects do not fall and liquids are not spilled into the enclosure through
openings.

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.

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.

COMMANDS AND FUNCTIONS

1) “VOLUME” CONTROL

The knob regulates the diffuser's volume.
This control does not affect the output “LINK” levels.

2) “INPUT SENSITIVITY” SENSITIVITY SWITCH

Position the switch in LINE to use a line level source (0 dB) or MIC to use a
microphone.

3) “LIMITER-PROTECTION” INDICATOR LIGHT

The “LIMITER-PROTECTION” indicator light comes on red during start (for a few
seconds) and when the internal audio limiter engages. This avoids the amplifier's
distortion and protects the loudspeakers against overloads.

4) “POWER ON - READY” INDICATOR LIGHT

The “POWER ON - READY” indicator light comes on green to indicate that the
amplifier is switched on and it is working properly.

6) “BALANCED INPUTS LINK” CONNECTORS

These balanced inputs can be used to connect balanced or unbalanced
microphones or audio sources at line level (0dB) (eg. preamplifier, mixer, recorder,
CD player, musical instrument, ...).
The balanced connector is connected in parallel and can be used to send the audio
signal to other amplified speakers, recorders or supplementary amplifiers.

7) POWER SWITCH “POWER”

This switch can be used to switch the diffuser on and off.

8) POWER CABLE SOCKET “MAINS”

Used for connecting the power cable supplied.

9) FUSE CARRIER “FUSE”

Mains fuse housing.

10) VOLTAGE CHANGE “VOLTAGE SELECTOR”

For changing the power voltage of the speaker (240/120V).
This switch is preset and protected by the manufacturer.

The blue indicator light indicates speaker start.

AMPLIFIER PANEL (FIG. 1)

SPEAKER FRONT (FIG.2)

1) INDICATOR LIGHT

5) EQUALIZATION CONTROL

This control permits the equalization of the speaker.
The "FLAT" central position permits a linear sound reproduction of the speaker. By
turning the control towards “VOICE”, the response curve of the speaker highlights
the mid frequencies while if the control is turned towards ”MUSIC”, the low and high
frequencies are highlighted.
This control does not affect the level of the output signal (link).
