IMPORTANT SAFETY INSTRUCTIONS
CAUTION: TO REDUCE THE RISK OF ELECTRICAL
SHOCK, DO NOT REMOVE THECOVER
(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 APPLIANCE TO RAIN OR
MOISTURE.
This symbol, wherever it appears, alerts you to the presence of uninsulated
dangerous voltage 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 appliance is operated.
Keep these instructions:
The safety and operating instructions should be retained for future reference.
Heed all Warnings:
All warnings on the appliance 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 appliance should be situated so that its location or position does not interfere with its proper
ventilation.
Heat:
Do not install the appliance near any heat sources such as radiators, heat registers, stoves, or other
appliance (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 appliance should be connected to a power supply only of the type described in the operating
instructions or as marked on the appliance. 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 at 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 tha
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 seaker 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.
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;
- Objects have fallen, or liquid had been spilled into the appliance;
- The appliance has been exposed to rain or moisture;
- The appliance does not appear to operate normally or exhibits a marked change in
performance;
- The appliance had been dropped.
The user should not attempt to service the appliance beyond that is described in the Operating
Instructions.All other servicing should be referred to qualified service personnel.

“NOISE GATE” function
NOISE GATE, or residual noise suppressor, is a function to reduce noise of the speaker
without input audio signal applied.
NOISE GATE starts to work when there is no audio signal on input, after a few seconds, it
sets the amplifier section in MUTE state . MUTE state is indicated by slow flashing, of
“MUTE/PROT” yellow led. As soon as the audio signal passes he input section, the
speaker is set out of MUTE status automatically.
This option can be enabled and disabled according to the follow procedure on the
amplifier’s module.
1) How to check NOISE GATE status
The NOISE GATE status is visualized by the leds located on the amplifier panel during
switching on the module.
Function enabled =all leds flashes steady for 5-6 second.
Function disabled = only “MUTE/PROT” yellow led flasches steady for 5-6 second
2) NOISE GATE enabled/disabled
NOISE GATE enabled/disabled can be done each time when switching ON and OFF the
amplifier module with “SET-UP MODE” selector on position “9 “(service use only).
To enable/disable NOISE GATE function follow this procedure:
- Amplifier switched OFF
- Set “SET-UP MODE” selector in position "9"
- Switch ON the amplifier module and check following:
* if “LIMITER" red led steady flashes for a few seconds, the NOISE
GATE is enabled.
* if “LIMITER" red led flashes fast for a few seconds, the NOISE
GATE is disabled
Warning!
After enabling or disabling the NOISE GATE function, switch off the amplifier, select
“SET-UP MODE” selector in any equalization position (except of "9" position) and
switch the system ON.

DVA system has obtained the TÜV certification for suspension of DVA T4 and DVA
S10 speakers through flybar stirrup DRK 10.
The report certifies that the maximum weight applying to DRK 10 flybar is 250Kg.
The DRK 10 flybar attests that the maximum number of DVAT4 is 16.
Refer to table 1 to determine the total weight borne by flybar according to the different
DVAT4 configurations.

The modular structure of DVA system permits mixed suspension configuration between
DVA T4 and DVA S10. It is necessary to consider that one DVA S10 hanging subwoofer
corresponds, in weight terms, to four DVAT4 speakers.
For this reason it is necessary to calculate the total weight according to the different
configurations.

Always install parts in accordance with these installation instruction!
Compile and store all DVAsystem documents in a safe place!
Warning
If the security norms and total weight calculations are not observed, dB Technologies
is not responsible for any possible damage to people and things.
During installation ensure that carrying structure of the system has added in the total
weight also the DRK 10 flybar weight, chain hoists, motors, cables and further weights.
§ 39, VBG 9a of the German employers' liability insurance association's accident
prevention regulations requires that load-carrying equipment be inspected by a qualified
