6. If the amplifier begins to emit any strange odours or smoke, switch it off immediately and disconnect the power supply cable.!
7. Do not connect this product to any equipment or accessories not specified.!
For suspended installation, only use the dedicated anchoring points and do not try to hang this product using HANDLES or elements that are
unsuitable or not specific for this purpose.!
Also check the suitability of the support surface to which the product is anchored (wall, ceiling, structure, etc.), and the components used for
attachment (screw anchors, screws, brackets not supplied by VL Audio etc.), which must guarantee the security of the system/installation over
time, also considering, for example, the mechanical vibrations normally generated by the transducer.!
To prevent the risk of falling equipment, do not stack multiple units unless this possibility is specified in the instruction manual.!
8. VL Audio strongly recommends this product is installed by professional qualified installers (or specialised firms) who can ensure correct
installation and certify it according to the regulations in force.!
THE ENTIRE AUDIO SYSTEM MUST COMPLY WITH THE CURRENT STANDARDS AND REGULATIONS REGARDING ELECTRICAL SYSTEMS.!
9. SUPPORTS AND TROLLEYS!
The equipment should only be used on trolleys or supports, where necessary, that are recommended by the manufacturer. The equipment/
support/trolley assembly must be moved with extreme caution. Sudden stops, excessive pushing force and uneven floors may cause the
assembly to overturn.!
10. There are numerous mechanical and electrical factors to be considered when installing a professional audio system (in addition to those
which are strictly acoustic, such as sound pressure, angles of coverage, frequency response, etc.).!
11. HEARING LOSS!
Exposure to high sound levels can cause permanent hearing loss. The acoustic pressure level that leads to hearing loss is different from person
to person and depends on the duration of exposure. To prevent potentially dangerous exposure to high levels of acoustic pressure, anyone who
is exposed to these levels should use adequate protection devices. When a transducer capable of producing high sound levels is being used, it
is therefore necessary to wear ear plugs or protective earphones. See the technical specifications in the instruction manual for the maximum
sound pressure the loudspeaker is capable of producing.
CAUTION: to prevent electric shock hazard, do not connect to mains power supply while grille is removed
SAFETY PRECAUTIONS

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 RCF 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. !
