CONNECTION TO THE INPUT SOCKETS
Only use power leads (unshielded) of a suitable section (at least 1.5 mm
2
)
and quality. Do not twist or bend the cables sharply and do not allow knots
to form; these can damage the insulation.
PAY SPECIAL ATTENTION TO THE PARALLEL IMPEDANCE:
If two 8-
Ω systems are parallel connected, the resulting load impedance
for the amplifier will be 4
Ω
, a value that is within the allowed range for
all amplifiers and amplified mixers manufactured by Montarbo
®
and by
most other manufacturers. When 3 systems are parallel connected, the
resulting total impedance decreases to 2.7 Ω; 4 parallel connected systems
will be 2
Ω.
Some amplifiers and amplified mixers cannot operate safely with such low
values of load impedance. Always check the technical specifications of your
amplifier or amplified mixer.
PRODUCT CARE AND MAINTENANCE
·
Position the speaker away from heat sources (radiators or other heat-
producing objects).
· Never expose the speaker direct sunlight or excessive vibrations or sudden
impacts.
· Avoid operating and storing the device in damp or dusty places: this may
cause malfunction and premature deterioration of performance.
·
Care should be taken to ensure that objects do not fall and liquids are not
spilled onto the device. In typical conditions of use, pay careful attention
to the position of the device in order to avoid the public, musicians,
technicians or anyone else from placing glasses, cups, food containers
and drinks, ashtrays or lit cigarettes on it.
·
Always leave the protection grille in place.
·
Use a soft brush or a jet of air to remove dust. Do not use alcohol,
solvents or detergents.
·
Take care of your connecting cables; wind them up to avoid knots and
twists.
·
Do not force connectors.
·
Before establishing any connection, make certain that the amplifier or
amplified mixer is switched off.
