passive loudspeaker system
W400P
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 W400P
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
®
socket 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
Ω
, 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
Ω
, and for
4 system to 2
Ω
.
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.
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.
