passive loudspeaker system

Product care and maintenance:
• Do not expose the enclosure to heat sources (lamps, lights,
high power light sources, 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 may lead to malfunctions and premature degrading
of specifications.
• 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.
• Always leave the protective grille mounted on the enclosure.
• Take care of your connecting cables. Make sure that they are not
damaged, knotted or twisted.
• Do not force connectors and controls.
• Before performing any connection, make certain that the power
amplifier or the powered mixer are switched off.

Connection to the input sockets.
• Use only loudspeaker cables (unscreened) having suitable cross
section (at least 2 x 1 mm 2 ) and quality. Do not twist or sharply
bend the cables and do not allow for knots to be formed, because
they may result in insulation damage.
• When using cables with jack plugs, make sure of using a sturdy
type, suitable for speaker use.
Do not use low quality connectors: they may easily lead to short
circuits or intermittent contacts.
Parallel connection of two or more systems.
• Connect the second system to the first one using the second
(free) socket. Both sockets may be used for input or output.
Obviously, it is always possible, if needed, to connect the power
amplifier to the first speaker system using the jack sockets, and the
first speaker system to the second one using the Speakon
or vice-versa.
• PAY SPECIAL ATTENTION TO THE PARALLEL IMPEDANCE:
if two systems are parallel connected, the resulting load
impedance for the amplifier will be 4 Ohms, a value that
is within the allowed range for all power amplifiers and
powered mixers manufactured by Montarbo and by other
manufacturers. For 3 parallel connected systems, the resulting
total impedance decreases to 2,7 Ohms, and for 4 system to
2 Ohms. Some power amplifiers and powered mixers cannot
operate reliably with these low values of load impedance.
Always check the technical specifications of your amplifier or
powered mixer for the value of the minimum load impedance.
