Product Care and Maintenance
• Never expose the enclosure to heat sources such as radiators
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 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.
• Take care of your connector cables. Make sure that they
are not damaged, knotted or twisted.
• Do not force connectors and controls.
• Do not remove the protection grid.
• Make sure the mains power switch is off ('0') before
starting any connection.
Power supply connection:
• Make sure the system is switched off ('0').
• Check that mains voltage corresponds to the voltage
indicated on the panel (beside the main socket).
• Use the three wire power cord supplied with the enclosure.
• Always connect it to a grounded outlet.
Connection to the mixer:
• Always make sure to use only heavy gauge, high quality
SHILDED cables (signal cables).
• Always make certain that the mixer and the powered
enclosures are switched off before connecting them.
This will avoid annoying noises and signal peaks, which can
also be dangerous for the enclosures themselves.
See 'connection example' at page 14.
If the mixer has balanced outputs:
- they can be connected to the XLR or to the Jack inputs,
without distinction, using balanced XLR or Jack 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.
If the mixer has unbalanced Jack outputs:
- use mono jack plugs (the balanced jack inputs become
automatically unbalanced).
Parallel connection:
• Always make sure to use only heavy gauge, high quality
SHILDED cables.
See 'connection example' at page 14.
- use XLR or Jack connectors without distinction.
