DESCRIPTIONS
In 2017 VL Audio moved into the forefront of the loudspeaker
technology with the introduction of the VEDA Series: a loudspeakers
range that was able to deliver perfect and powerful sound with a
lightweight cabinet strong enough to withstand everyday use. The
VL Audio R&D team kept evolving the VIVA technology during the
last decade, developing reference products such as the VIVA-718D
The VL Audio team always has the pertormer’s needs at the
forefront of the design in order to create new lines of speakers with
renewed features, Improved sound clarity and definition and even
lighter weight systems.
The latest iconic design is the VIVA Series: an evolution in the
active loudspeaker technology with a revolutionary design and sound.
Every detail of the 7 Series has been carefully studied in order to offer
musicians and professionals the perfect tool to amplify their performance,
night after night. High quality materials, precise manufacturing, careful
assembly and extensive quality control procedures complete the
groundbreaking design work of the VL Audio R&D team.
COMPONENTS
All the transducers in the VIVA Series speakers feature high
power magnets in order to guarantee a better performance and
make for easier transportation.
All Compression drivers and Transducers are precision built taking
advantage of VL Audio superior moulding, assembly technologies and a
wealthof professional knowledge and experience dedicated to achieving
extremely high standards.
AMPLIFIERS
VIVA 7 Series two-way speakers are equipped with a new generation
of 2,800 Watt Class-D bridge Amplifier.The result of this is very high
output,extremely low distortion and an incredible natural sound. Each
amplifier presets both XLR/jack (Combo) balanced inputs, XLR output
link,volume and a switchable Preset Mode (80Hz/90Hz/100Hz/
120Hz/End fire/Inverted stack), additional MIC/Line input switch. The
amplifier features a solid mechanical aluminium structure which not
only stabilize the amplifier during transportation but also assist in
the heat dissipation.
VIVA 7 Series amplifiers presents PFC power supply section in
order to produce maximum output even in case of tension drops
from main supply.
CABINETS
The new loudspeaker design looks aggressive whilst retaining
familiar VIVA ergonomics and is the result of extensive combined
functional and acoustic research.
The VIVA-718D two-way system cabinets are made of the best Baltic
birch plywood coated with a textured black finish. The subs are stackable
and light-weight, for easy set-up and tear down, thanks to the ergonomic
handles. A pole receptacle on top and side allows the use of the box
in various configurations. The powder coated front grille integrates a
special transparent-to-sound foam backing on the inside to further
protect the transducers from dust.
VIVA-718D
VIVA-718D is one of the most powerful 18” subwoofers in pro-sound
category. Featuring a high power, hypervented 18” woofer, with 4”
inside/outside voice coils, this cabinet is designed to deliver a serious
amount of low frequency. The amplifier section features 2,800 Watt
Class-D bridge Amplifier. with full DSP , the VIVA-718D can perform in
the most demanding situations. The input board includes volume
control, ground switch, preset switch, xover, end fire, inverted stack.

6 CLIP LED
The amplifier has a built in limiter circuit to prevent
cipping of the amplifiers or overdriving the transducers.
When the soft clipping circuit is active the LED blinks
orange. It is okay if the limit LED blinks occasionally.
If the LED blinks frequently or lights continuously, turn
down the signal level.

CONNECTIONS
The XLR connectors use the following AES standard:
PIN 1 = GROUND (SHIELD)
PIN 2 = HOT (+)
PIN 3 = COLD (-)
BEFORE CONNECTING THE SPEAKER
On the back panel you will find all the controls, the signal and current inputs. At first verify that the voltage selector on the speaker
is in proper position for your country (115 Volt or 230 Volt).
The switch shall be in proper position (unless moved from unauthorized people), but a fast check will avoid problems. In case is
necessary to change the voltage please call your vendor or authorized VL Audio SERVICE CENTRE. This operation require the
substitution of the fuse value and is reserved to an VL Audio SERVICE CENTRE.
BEFORE TURNING ON THE SPEAKER
At this point you can connect the power supply cable and the signal cable, but before turning on the speaker make sure that the
volume control is at the minimum level (even on the mixer output). It is important that the mixer is already ON before turning on the
speaker. This will avoid damage to the speakers and noisy “bumps” due to turning on parts on the audio chain. It is a good practice
to always turn on speakers at last and turn them off immediately after the show. Now you can turn ON the speaker and adjust the
volume control to a proper level.
INSTALLATION
A 35 mm socket for mounting the loudspeaker on a speaker stand is provided in the bottom of the cabinet. VL Audio speakers
MUST be used only with approved rigging hardware.
WARNING:
Never suspend VL Audio speakers by there handles. Handles are intended for transportation, not for rigging.
WARNING:
The use of these speakers with Stand and Pole Mount accessories can be done by qualified and experienced personnel
only, trained appropriately on professional systems installations. In any case it’s the user’s final responsibility to ensure the system
safety conditions and avoid any danger or damage to people, animals and objects.
WARNING:
To use this product with the subwoofer pole-mount, before installing the system, please verify the allowed configurations
and the indications regarding the accessories, on the VL website to avoid any danger and damages to people, animals and objects.
In any case, please assure the subwoofer which is holding the speaker is located on an horizontal floor and without inclinations.
PROTECTIONS
VIVA Series active speakers are equipped with a complete system of protection circuits. Two led on the amplifier back panel indicate
the working status of the amplifier: the green led indicate that the speaker is ON and the red led is on when the protection circuit
is active. The circuit is acting very gently on audio signal, controlling level and maintaining distortion at acceptable level. If this led
is ON for a long period is better to reduce immediately the signal level from the mixer or from the speaker volume control.
