Important !
Product care and maintenance:
• Do not expose the enclosure to heat sources (heaters or other
products that produce heat).
• Never expose the enclosure to direct sunlight, excessive vibrations
or mechanical shocks.
• Avoid operating and storing the enclosure in damp or dusty
places: this may lead to malfunctions and premature degrading
of specifications.
• Avoid using the enclosure close to strong sources of electro-
magnetic interferences (e.g. video monitors, high power electrical
cabling). This may lead to degradation of audio quality.
• When setting up the system up outdoors, be sure to protect it
against rain.
• Care should be taken so that objects do not fall and liquid is
not spilled onto the enclosure. In public event don't let people,
musicians, technicians or anyone put glasses, cups, ashtrays or
cigarettes on the enclosure.
• Always leave the protective grid mounted on the enclosure.
• Use a soft brush or a jet of air to clean the enclosure.
Do not use alcohol, solvents or detergents.
• Take care of your connector cables. Make sure that they are
not damaged, knotted or twisted.
• Do not force connectors and controls.
• Make sure the mains power switch is off ('0') before starting
any connection.
Power supply connection:
• Make sure the mains power switch is off ('0').
• Check that mains voltage corresponds to the voltage
indicated on the panel, under the mains socket.
• Use only the factory supplied mains cable or, if a different plug
style is needed, a suitable cable with a ground connection and
marked with the safety approvals valid in the country of use
Connection to the mixer:
If the mixer has XLR balanced outputs:
- use standard balanced XLR connectors.
If the mixer has XLR unbalanced outputs:
- in this case, unless using a Montarbo mixer, make sure that the
XLR outputs on the mixer are unbalanced to IEC 268 standard:
1 = GND, 2 = HOT, 3 = GND.
If the mixer has JACK balanced outputs (stereo jacks):
- it is possible to use stereo Jack-stereo Jack cables or stereo
jack-XLR adapters, wired according to IEC 268:
pin 1 = ground (sleeve), pin 2 = tip, pin 3 = ring.

3-way, bi-amplified, active loudspeaker systems
If the mixer has JACK unbalanced outputs (mono jacks):
- use suitable Jack-XLR male adapters unbalanced according
to IEC 268: pin 1=ground, pin 2= tip, pin 3=ground
☛ See 'connectors' at page 15.
• Always use only heavy gauge, high quality SHIELDED cables
(signal cables).
• Always make sure that the mixer and the powered enclosures
are switched off before connecting them.
This will to avoid annoying noises and signal peaks, which can
also be dangerous for the enclosures themselves.
Parallel connection of two or more systems:
• Always make sure to use only heavy gauge, high quality
SHIELDED cables.
Connect the LINK OUT of the first system to the LINK IN of the
second one, the LINK OUT of the second system to the LINK IN
of the third one and so on.

Hanging the T18A speaker. Tips and warnings.
The T18A loudspeaker system is equipped with M10 threaded
fittings to accommodate accessories for suspensions of the
enclosures. The first thing to do is decide which of the anchoring
points will be used for suspension. Once the anchoring points have
been determined, remove the dummy screws and replace them
with M10 eye bolts.
ATTENTION: whenever the eye bolts are removed you must be sure
to replace them with the dummy screws.
Please bear in mind that all hanging installation jobs are carried out
under the sole responsibility of the person doing the actual work
and must be done in full compliance with all the applicable safety
rules and regulations.
We do not attempt to provide detailed guidelines for all the potential
ways in which these extremely flexible systems can be installed,
but do want to remind you that to ensure a safe installation, it is
necessary to adhere to the following:
1 - When hanging the speakers, use only means of suspension (in
accordance with the safety regulation valid in the country of use)
having a carrying capacity rated and guaranteed by the manufacturer.
2 - Never depend on only one means of suspension for hanging
speakers (for example one chain); always use at least two of them
and make sure they are sufficiently strong. So, if one fails the other
will sustain the load.
3 - Never hook a speaker to the one above. Each speaker must be
individually hooked to the supports.
4 - Always make sure that the truss structure intended to support
the speakers is sturdy enough to hold their weight, even under
stressful, adverse conditions. Always consider the effect of additional
loads (for example, the wind in case of outdoor installations).
