CHARACTERISTICS AND PROTECTION

Front Grille
The speakers's components in the box are protected by 1.2mm metal steel grille covered
by foam on backside.
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.

DESCRIPTION
The DVX series bi-amped speakers are equipped with DIGIPRO series class D amplifier.
This high-efficiency amplifier delivers high output power in a compact size and low weight.
Thanks to its high efficiency the cooling of the amplifier module is obtained statically, thus
avoiding the use of a fan.
The power supply circuits of the DIGIPRO amplifier has been conceived to work in full-
range mode; thanks to the SMPS (Switched-Mode Power Supplies) technology with PFC
(Power Factor Correction) the operation with supply voltages between 100 Vac and
240Vac is guaranteed by ensuring the same sound performances even with floating and
non-stabilized power supply systems.
DVX D12
The D12 bi-amped active speaker is equipped with a
DIGIPRO amplifier delivering 500W RMS for the bass
section and 250W RMS for the high frequency section.
The D12 active two-way speaker features a neodymium 12"
" (voice coil 3") woofer and a neodymium 1.4" (voice coil 2.5")
compression driver installed on a 60°x40° aluminium CD-
horn.
"
The speakers' horizontal directivity is 60° by default factory
setting.
The speaker is made of 15mm birch ply wood, the 3 handles,
the 6 flytracks, the 6 M10 threads and the 4 flypins located on
the sides and the back of the spekaer are enabling easy
transport and installation.
The speaker has been designed to be used also as stage
monitor (45° angle). By rotating the horn you can maintain the
same coverage angle also when the speaker is used as
monitor.
In the bottom of the box there is a standard pole mount cup
(D36mm) made of aluminium.
DVX D15
The D15 bi-amped active speaker is equipped with a
®
DIGIPRO amplifier which is capable to deliver 500W RMS for
the bass section and 250W RMS for the high frequency
section.
