series last generation. These highly efficient amplifiers provide high power with limited weight and dimension. Thanks to the low power dissipated, the cooling of the amplifier module does not require a fan. The digital preamplifier with DSP (Digital Signal Processing) controls the audio crossover between the acoustic components, the frequency response, the limiter, and the acoustic alignment. A selector enables to select one of two different equalizations - “FLAT” or “PROCESSED“ - to provide high versatility for the different applications. The amplifiers DIGIPRO

for LVX 12 and LVX 15 speakers use power supplies featuring SMPS (Switched-Mode Power Supplies) technology. This technology increases power supply efficiency and minimizes its weight.

LVX 8 The LVX 8 bi-amped active speaker is equipped with a DIGIPRO

amplifier delivering 400W (Power PRG). LVX 8 active two-way speaker features woofer 8” (voice coil 1,5”) and a driver 1” (voice coil 1”) on 90°x70°horn. The speakers’ horizontal directivity is 90° by default factory setting. The speaker is made of 12mm ply wood, the one top handle housing and the 10 M8 threads located on the sides and the back of the speaker are enabling easy transport and installation. The speaker has been designed to be used also as stage monitor (40° angle), by rotating the horn you can maintain the same audio coverage angle of high frequencies also when the speaker is used as monitor. In the bottom of the box there is a standard pole mount cup (D36mm).

LVX 12 The LVX 12 bi-amped active speaker is equipped with a DIGIPRO

amplifier delivering 800W (Power PRG). LVX 12 active two-way speaker features woofer 12” (voice coil 1”) and compression driver 1” (voice coil 1,5”) on a 90°x40° horn. The speakers’ horizontal directivity is 90° by default factory setting. The speaker is made of 15mm birch plywood, the three plastic handles and the 12 M10 threads located on the sides and the back of the speaker 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 audio coverage angle of high frequencies also when the speaker is used as monitor. In the bottom of the box there is a standard pole mount cup (D36mm).

LVX 15 LVX 15 bi-amped active speaker is equipped with a DIGIPRO

amplifier delivering 800W (Power PRG). LVX15 active two-way speaker features a woofer 15” (voice coil 2”) and a compression driver 1” (voice coil 1,5”) on a 90°x40° horn.

1) “Balanced Input” - “Link” - “Input Link” CONNECTORS

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

2) “Ready” INDICATOR LIGHT

This indicator shows green to indicate that the main power voltage is correct. The LED shows green normal operating conditions.

3) “Signal” INDICATOR LIGHT

This indicator shows green to indicate the presence of the audio signal (at a level of -20dB).10

This indicator shows red to indicate that the internal limiter circuit has tripped. This prevents amplifier distortion and protects the speakers against overloads.

5) “Sensitivity” INPUT SENSITIVITY CONTROL

This control adjusts the sensitivity of the signal amplifier input. This control does not affect the “Link” - “Input - Link” output level

This two-way switch allows to choose between two different system presets. The “Flat” position allows linear response of the speaker, which is mainly suitable for the “live” application. The “Processed” position emphasizes the low frequency and regulates the mid frequency. It is suitable for music play back

7) “Input Sens” SWITCH

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

8) POWER CABLE SOCKET “MAINS”

Used for connecting the power cable supplied.

This switch can be used to switch the diffuser on and off.LVX Professional Active Speaker

Front Grille The speakers’s components in the box are protected by 1,2mm (LVX 8 and LVX 10) or 1,5mm (LVX 12 and LVX 15) 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 and 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, the front LED lights up (if enabled) and on the amplifier module the “Ready” green LED only remains steadily on. In case of severe failure of the speaker, the LED on the front panel flashes several times and on the amplifier module, the “Limiter” red LED flashes and the speaker switches to “mute”. Failure indications and safeties The microprocessor is able to signal three different kinds of failure by flashing the “Limiter” red LED on the amplifier panel before the lighting up of the “Ready” green LED. The three types of failure are: - WARNING: a non-severe error or auto-ripristinate malfunction is detected and the performance of the speaker is not limited - 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 center to solve the issue. - FAILURE: a severe malfunction is detected. The speaker switches to “mute”. Flashing

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 after these tests the red “LIMITER” LED is still on, please contact an authorized service center.12

Loudspeaker allows to maintain the same coverage angle by featuring a rotating horn. The speakers are always supplied by the manufacturer with the horn positioned horizontal by default at 90° for LVX series. If you wish to change the coverage angle (Fig. 1): - 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 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.

5. 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 - floor (monitor) - on speaker stands - suspended with support rails or brackets supplied by the manufacturer

WARNING Never use the handles to hang the speaker!

WARNING To hang the loudspeaker use only one eyebolt for each hanging point The hanging points are of M8 threads for LVX 8 / LVX 10 and M10 threads for LVX 12 / LVX 15 Do not unscrew both bolts recessed in the housing! NO! YES! YES!LVX Professional Active Speaker
