bi-amped, active loudspeaker system

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.
• Never operate and store the enclosure in damp or dusty
places: this will avoid malfunctions and premature degrading
of specifications.
• Avoid using the enclosure close to strong sources of
electromagnetic interferences (e.g. video monitors, high
power electrical cabling).
This may lead to degradation of audio quality.
• Care should be taken so that objects do not fall and liquid
are not spilled into the enclosure. In public event don't let
people, musicians, technicians or anyone put glasses, cups,
ashtrays or cigarettes on the enclosure.
• Use a soft brush or a jet of air to clean the enclosure.
Do not use alcohol, solvents or detergents.
• Do not remove the protective grid.
• 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.
Hanging the speakers. Tips and warnings.
The M22A 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).
Connection to the mixer:
- If the mixer has XLR balanced outputs: use standard
balanced XLR connectors.
- If the mixer has XLR unbalanced outputs, unless you are
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.
☛ See 'connectors' and 'connection example' at pages
17 and 18.
• 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 shall to avoid annoying noises and signal peaks, which
can also be dangerous for the enclosures themselves.
Parallel connection of two or more systems:
• Always use only heavy gauge, high quality SHIELDED
cables (signal cables).
Connect the first W22A's LINK OUT to the second's LINK IN,
the second's LINK OUT to the third LINK IN, and so on.
