Be aware of sound levels.
Be aware of excessive loads.
Kg
in outdoor envinroments it is advisable to have an anemometer. Flying loudspeakers overhead at
wind force higher than 6 bft (20 knots), is not recommended.
If the wind force exceeds 8 bft (35 knots):
- Make sure that no people remains in the closer proximity of the array
- Lower and secure the array (Flown & Clustered speakers).
Pay attention, excessive loads can cause permanent personal injury. Please check and respect the
regulations relating to maximum load handled per person.
Loudspeaker systems are capable of producing very high sound pressure levels (SPL) which can
instantaneously lead to permanent hearing damage to performers, production crew and audience
members. Hearing damage an also occur at moderate level with prolonged exposure to sound. Check
the applicable laws and regulations relating to maximum sound levels and exposure times.
In connection with a laser inclinometer take precautions to prevent anyone from looking directly into
the laser beam and wear appropriate eye protection. Laser beams can cause permanent personal
injury.

Quadra2, "The Two", extra-small sized, is the smallest speaker of the range. With all sides of 100 mm, it can
be quite literally handled in your hands. Weighs no more than 0,5 Kg and it can t wherever you need,
even in the most unthinkable places.
Two, is the transducer dimension (2in.), it's the only one installed on-board and it's the smallest Loud Pro
Full Range driver ever used before.
Logically supported in the lower frequencies response, it is capable of delivering an extraordinary sound
impact as you cannot expect from speakers of that size.
Designed to be easily integrated in all kind of installations where a distributed line is required, such as
malls, shops, restaurants, lounge bars, it also shows itself extremely useful for residential uses and private
ceremonies, physically blending in the architecture and disappearing from the sight, mostly thanks to its
ultra-compact dimensions and to the customizable colors of the box and the front cloth.
A complete range of accessories makes it happen. Quadra2 can be wall/ceiling mounted using its own
bracket xable on both sides (Left/Right & Top/Bottom), due to the four M6 threaded inserts.
All Quadra Full Ranges can be installed on a microphone stand or on a standard speaker stand, this one
using a dedicated bracket adapter. The speakers can be tilted both cases.
A pole mounting kit allows the speaker to be installed on top of a Sub/Bass unit (QuadraS - HP, NucleoS,
GammaS8), boosting its LF contour down to 45 Hz as a stand alone system.
It's reasonable to think this system usable for small-sized live performance venues, but only if properly
congured.
The rear side features a single 4 pole Phoenix™ connector, extremely helpful for installed applications.
Signicant construction criteria, combined with the latest technologies and innovative materials, ensure
a great reliability over time.
Quadra2 cabinet is constructed from marine Birch-ply and has an impact and weather protected PCP
(Polyurea Cabinet Protection) nish.
A color range (RAL Architectural program) makes all Quadra speakers, for an easy integration, most appro-
priate for each installation depending on the architectural and furniture requirements.
Applications: Conference Halls, Theaters, Shops & Commercial Centers, Small Clubs, Pubs, Lounge Bars &
Restaurants, Houses & Apartments, Ceremonies.

Quadra5, "The Five", is the mid-sized speaker of the range. With all sides of 160 mm, it can be quite literally
handled in your hands. Weighs no more than 2 Kg and it can t wherever you need with ease.
Five, is the transducer dimension (5in.), featuring a coaxial Full Range driver, that provides an exceptional
wide frequency response from 90 Hz up to 22 kHz.
The Neodymium tweeter (0.55in.), coaxially mounted on the same Mid-bass magnet structure, delivers a
really smooth and at response for a clear and precise Mid-Hi frequency reproduction.
Logically supported in the lower frequencies, Quadra5 is capable to perform an extraordinary sound

Six, is the transducer dimension (6.5in.), featuring a coaxial Full Range driver tuned in a bass reex vented
box. The system provides a really wide frequency response from 75 Hz up to 22 kHz.
The Neodymium tweeter (0.55in.), coaxially mounted on the same Mid-bass magnet structure, delivers a

QuadraS - HP maintains the same look of all Quadra speakers, it's boxy in appearance but simply elegant!
It's an installation-specic Sub/Bass unit, featuring a single long excursion 8in. in a Band-pass design, that
provides incredible High Performances, even if a small diameter transducer is in charge of it.
The Band-pass design produces signicant performance benets in terms of eciency, low distortion and
deepest bass extension down to 45 Hz (40 Hz @ -10dB), not comparable to traditional vented box of equal
size, always providing a clear and smooth response for the maximum listening comfort.
QuadraS - HP has been designed to increase the Quadra Extended Range speakers headroom, boosting
their LF contour and oering a really wide operating range from 40 Hz up to 20 kHz.
The close coupling of the two sub-systems (Sub/Bass and Extended Range speakers), thanks to the right
alignment, allows to obtain a true stand alone Point source element, delivering a coherent wavefront
output across the entire reproducible frequencies spectrum.
Two M6 threaded inserts on the top panel of QuadraS - HP make it easier and faster. A M20 built-in
adapter, on the same top panel, allows all Quadra speakers to be pole mounted.
QuadraS - HP can also be hanged on the ceiling, a special bracket favors the hanging of this unit, with or
without each Quadra Extended Range combined together.
QuadraS - HP is ideally suited for permanent or temporary installed specic applications and it is also
particularly useful for all applications where high standard SPL are not required, as well as distributed
sound in small venues, Small clubs, Lounge Bars & Restaurants and more others.
it is also an ideal companion for Home Dolby Cinema applications as well as Broadcast and Studio Record-
ing, thanks to its ability to extend the response toward the low-end region.
Signicant construction criteria, combined with the latest technologies and innovative materials, ensure
a great reliability over time. QuadraS - HP cabinet is constructed from marine Birch-ply and has an impact
and weather protected PCP (Polyurea Cabinet Protection) nish.
