CHARACTERISTICS AND PROTECTION
The speakers’s components in the box are protected by 1,2mm DVX D8HP and D10 HP
DVX D12HP and D15 HP metal steel grille covered by foam on backside.
Front Grille
()
or 1,5mm ( )
Cooling
Thermal control is provided by the internal microprocessor which, by means of two sensors,
controls the temperature of the amplifier and of the power supply, avoiding overheating by
limiting the overall volume.
In case of overheating (> 80 degrees) the volume decreases proportionally to the
temperature increase, making the change unnoticeable.
The correct volume and all the functions are automatically restored when standard
operating temperatures are reached.
Switch on
The amplifiers are equipped with a microprocessor to control the DSP and the amplifier.
The correct switch on of the amplifier is ensured by an initialization procedure; during this
test stage the LEDs ( LIMITER , SIGNAL AND READY ), located on the amplifier
module, remain off for approx. 2 sec.
At the end of the switch on procedure, on the amplifier module, the READY green LED
only remains steadily on.
In case of severe failure of the speaker, on the amplifier module, the LIMITER red LED
flashes. The speaker switches to “mute”.
Failure indications and safeties
The microprocessor is able to signal three different kinds of failure by flashing the “LIMTER”
red LED on the amplifier panel before the lighting up of the “READY” green LED. The three
types of failure are:
1) WARNING: a non severe error or auto-ripristinate malfunction is detected and the
performance of the speaker is not limited
2) LIMITATION: an error is detected and the performance of the speaker is limited (the
sound level is reduced by 3dB).
This does not affect the operation of the speaker since it continues to operate.
However, it is necessary to call the service centre to solve the issue.

3) FAILURE: a severe malfunction is detected. The speaker switches to “mute”.
Flashing Indication
1 or 2 Warning
3 or 4 Limitation
from 5 to 8 Failure
In case of failure, the “READY” green LED remains off.
Perform the checks listed below:
- Check if the speaker is properly connected to the power supply.
- Make sure that the power supply is of correct voltage.
- Check that the amplifier is not overheated.
- Disconnect the speaker from the mains power supply, wait for a few minutes and
connect it again.
If this error signaling remains active contact the authorized service center to resolve the
problem.
WARNING
Never use the handles to hang the speaker!
ROTATING HORN
When used horizontally, the loudspeaker allow to maintain the same coverage angle by
featuring a rotating horn.
The speakers are always supplied by the manufacturer with the horn positioned horizontal
at 90°by default for D8 HP and D10 HP speakers and with the horn positioned horizontal at
60°by default for D12HP and D15 HP speakers.
If you wish to change the coverage angle (FIG.A page 33, 34):
- unscrew the fixing screws of the grille
- remove the front protective grille by slightly pressing on one side and taking the grille
off the recessed slots
- unscrew the eight fixing screws of the horn
- rotate the horn in the desired position (the horn should never be removed from the
driver!)
- tighten the fixing screws of the horn
- put the grille back in the recessed slots and tighten the screws of the grille.
LOUDSPEAKER INSTALLATION
WARNING
Make sure that the loudspeaker is securely installed in a stable position to avoid any
injuries or damages to persons or property.
For safety reasons do not place one loudspeaker on top of another without proper
fastening systems. Before hanging the loudspeaker check all the components for
damages, deformations, missing or damaged parts that may compromise safety during
installation.
If you use the loudspeakers outdoors avoid places that are exposed to bad weather.
The loudspeaker has the following mounting options:
- bookshelf (Fig. 1 page 35)
- floor (monitor) (Fig.2 page 35)
- on speaker stands (Fig.3 page 36)
- suspended with eyebolts (Fig.4 page 36,37) or flytracks - excluded DVX D8HP -
(Fig.5 page 37)
- brackets supplied by the manufacturer
EXACT!
WRONG! EXACT!
WARNING only for DVX D8HP
To hang the loudspeaker use only one eyebolt for each hanging point
The hanging points are of M8 threads.
Do not unscrew both bolts recessed in the housing!
